One such abnormality is known as mesial temporal sclerosis, in which the inner part of the temporal lobe, a section of the brain that sits above the ear on both sides and mediates emotions and memory, becomes scarred.

They most commonly arise from the mesial temporal lobe, particularly the amygdala, hippocampus, and neocortical regions.Trescher, William H., and Ronald P. Lescher 2000, p. 1750. A common associated brain abnormality is mesial temporal sclerosis. Mesial temporal sclerosis is a specific pattern of hippocampal neuronal loss accompanied by hippocampal gliosis and atrophy.

The mesial view shows a slight tipping of the crown to the lingual. Both roots have flutings but they are more prominent on the mesial root. The mesial root is broader buccolingually and its apex is more blunted. The height of contour on the buccal is in the gingival third and the occlusal two thirds of the surface is flat.
|
|
From a lingual aspect, they have well developed mesial and distal marginal ridges and a well-developed cingulum. A prominent lingual ridge divides the lingual aspect in half and creates the mesial and distal lingual fossae between the lingual ridge and the marginal ridges. From a proximal aspect, they resemble the incisors, but are more robust, especially in the cingulum region. Incisally, they are visibly asymmetrical, as the mesial incisal edge is slightly shorter than the distal incisal edge, which places the cusp slightly mesial to the long axis of the tooth.
|
|
These are found on all primary teeth but only on the permanent molars. Cusp ridges are ridges that radiate from cusp tips. There are two marginal ridges, mesial and distal, present on all teeth. On anterior teeth, they are located on the mesial and distal borders of the lingual surface; on posterior teeth, they are located on the mesial and distal borders of the occlusal surface.
|
|
The mesial view of this tooth considers the portion of the tooth visible from the side closest to where the middle line of the face would be.the mesial axis should be parallel to the midline. The mesial side of the maxillary central incisor shows the crown of the tooth as a triangle with the point at the incisal edge and the base at the cervix. The root appears cone shaped with a blunt apex.
|
|
Furthermore, a cross-section of the tooth at the cervical line would show a general triangle appearance. One of the triangle's sides would be the facial surface, and the other two sides would be the mesial side and the slightly shorter distal side. Mesial view.

X-ray film depicts some of the teeth in the lower right quadrant. The arrows point in the following directions: distal ←, mesial →, coronal ↑, apical ↓. complete maxillary denture. The green line, indicating the dental midline, is the defining line when it comes to mesial-distal direction.
|
|
The abdomen underside is grey with a mesial black line. The forewing upperside is also grey, with a black basal patch on the hind margin and a black line in the discal cell. The hindwing upperside is grey with diffuse, dark, basal mesial and submarginal bands.
|
|
The distal view of this tooth considers the portion of the tooth visible from the side furthest from where the middle line of the face would be. This side of the tooth is very similar to the mesial side. A greater portion of the tooth surface facing the lips is visible from this view compared to the mesial view because the labial surface tilts distally and lingually. Also, the cervical line curves less in comparison to the mesial view.
|
|
The movable connector attaches the pontic to the mesial abutment, enabling this abutment tooth limited movement in a vertical direction.
|
|
As the anatomical crown and root tapers towards the apex, the mesial-distal dimension decreases, and so the mean mesial-distal dimension at the marginal crest of bone, which lies approximately 2 mm apical to the CEJ, is smaller. The tooth has the apico- coronal distance from the marginal crest of bone to the contact point in order to increase from the much narrower mesial-distal dimension to the greater mesial-distal dimension, and this distance is subgingival (below the gum line). Running room refers to this subgingival apico-coronal distance. In general, it is recommended that implants be given approximately 3mm of running room in compliance with the rule of thumb that implants should be placed as deep as necessary and as shallow as possible.

Universal numbering system). Tooth #3, the upper right first molar, has an MO (mesial-occlusal) gold inlay. This molar is both posterior, as well as distal, to the premolars in front of it. Most of the principal terms can be combined using their corresponding combining forms (such as mesio- for mesial and disto- for distal).
|
|
Most of the surfaces are smooth, but the mesial surface of the root may have a developmental groove or a concavity.
|
|
The anterior outer tritor is situated on a prominence located labially and near the mesial one third of the middle tritor.
|
|
Compared to the maxillary central incisor, the maxillary lateral incisor has more rounded mesial and distal incisal angles. The distal outline is always more rounded. The root is often tapered distally, often with a sharp curve distally and to an apex; however, the curve can be absent. The mesial and distal contacts are more cervical than the central incisor.
|
|
The upper lateral teeth of the species have a long, acute, strongly sigmoid main cusp. This cusp is serrated and has a dispal cusplet. The main cusp of the antero-lateral teeth is triangular and carries eight mesial cusplets that increase in size along the lower mesial face. The antero-lateral teeth have six main cusplets, the sixth of which is very small.
|
|
Each arch also possesses its own midline, which can be used to refer to the location of contact between the mesial surfaces of the central incisors. Thus, if an individual's mandibular teeth are shifted over to the left in a mesial-distal dimension, by 2 mm, for example, that individual's midline would be said to be deviated 2 mm to the left.
|
|
Epilepsy of the mesial temporal lobe is associated with HHV-6 infection. Within this region of the brain exists three structures: the amygdala, hippocampus, and parahippocampal gyrus. Mesial temporal lobe epilepsy (MTLE) is the most common form of chronic epilepsy and its underlying mechanism is not fully understood. Researchers consistently report having found HHV-6 DNA in tissues that were removed from patients with MTLE.
|
|
The mandibular central incisor is the tooth located on the jaw, adjacent to the midline of the face. It is mesial from both mandibular lateral incisors.
|
|
The pterygoids, on both anterior and middle aspects, show a considerable number of small pointed teeth. The marginal teeth are serrated on the mesial and distal edges.
|
|
Variations in the MT-ND4 gene are associated with age-related macular degeneration (AMD), Leber's hereditary optic neuropathy (LHON), mesial temporal lobe epilepsy (MTLE) and cystic fibrosis.
|
|
Premolars are found distal to canines and mesial to molars. They are divided into first and second premolars. The functions of premolars vary. There are no deciduous premolars.
|
|
A cantilever is a bridge where a pontic is attached to a retainer only at one side. The abutment tooth may be mesial or distal to the pontic.
|
|
The offset lies at an angle to the mesio-distal axis of the tooth, and causes the mesial portion of the central groove to be located further buccally than the distal portion. This buccolingual shift correlates with a relative difference in size between the mesial and distal cusps on these teeth - the mesiolingual cusp is larger than the mesiobuccal cusp, but the distobuccal cusp is larger than the distolingual cusp. It also allows for the buccal groove to be located mesial to the lingual groove which is mandatory to accommodate the relative sizes of the three cusps on the buccal and two cusps on the lingual of the occlusal surface of the tooth.
|
|
Most of the remaining permanent teeth are preserved in their crypts. ZT 299’s sex was determined by observing the beginnings of a deep mesial groove in the canine crowns.
|
|
The lingual fossa is bordered incisally by the lingual incisal edge, mesially by the mesial marginal ridge, distally by the distal marginal ridge, and cervically by the cingulum. Developmental grooves are found on the cingulum and lying into the lingual fossa. This side of the tooth tapers in size from the labial side of the tooth. As a result, the mesial and distal sides of the tooth are further away on the labial side than on the lingual side.
|
|
The curvature of the cementoenamel junction (CEJ) or the cervical line sharply inclines towards the incisal ridge. The mesial view of the lateral incisor fits into the geometric shape of a triangle.

A study published by Ghosh et al. in 1996 stated that the mean maxillary first molar distalization was 3.37 mm, with a distal tipping of 8.36° and the mean reciprocal mesial movement of the first premolar was 2.55 mm, with a mesial tipping of 1.29°. They also stated that the eruption of maxillary second molars had minimal effect on distalization of first molars. In addition, the reported increase of Lower Anterior Facial Height for patient's who had pre-existing vertical growth.

|
The palpus is grey and the thorax underside darker. The abdomen underside has ill-defined buffish-grey mesial patches on the proximal segments. The hindwing upperside base is more extensively black than in similar species.
|
|
Varying symptoms may be used to determine which of the two diseases the subject has. Amnesia, seizures, and mesial temporal lobe structural abnormalities are features of LE, whereas myokymia, hyperhydrosis, and insomnia favor Morvan's Syndrome.
|
|
The buccal cusp ridges exhibit slight concavities that extend over the buccal surfaces as developmental grooves into the gingival embrasure. The contacts with adjacent teeth are in the occlusal third of the tooth with the distal height of contour slightly closer to the gingival than the mesial height of contour. The root is generally straight with slight curvature to the distal in the apical third. Viewed from the mesial or distal the buccal height of contour is in the gingival third of the tooth.

Macroglossum eichhorni is a moth of the family Sphingidae. It is known from the Solomon Islands. The length of the forewings 24–25 mm. The head and thorax uppersides are brown, with a dark mesial stripe.
|
|
Gracey curettes have sharp cutting edges on only one side of their blades. There are two site-specific Gracey curettes -- posterior mesial (white ring) and posterior distal (blue ring), in addition to the anterior curette (red ring).
|
|
Furthermore, there was no mortality in the surgery group, while there was seizure-related mortality in the medical therapy group. Therefore, ATL is considered the standard of care for patients with medically intractable mesial temporal lobe epilepsy.
|
|
For maxillary first molars, the mean root trunk length is 3-4 mm on the buccal aspect, and 4-5 mm on the mesial aspect and 5-6 mm on the distal aspect. As with mandibular molars, the root trunk lengths for maxillary second and third molars are either the same or slightly greater than for first molars, although the roots may be fused. For maxillary first premolars, there is a bifurcation 40% of the time and the mean root trunk length is 8 mm from both mesial and distal.
|
|
The portion of the central groove between the central pits is termed the Lewis offset and is mandatory to account for the locations of the buccal and lingual grooves (buccal groove being more mesial than the lingual groove while they are parallel). From the buccal (buccal view), two roots are present. The distal root is generally straighter, although both often have a slight distal curvature. The heights of contour on the mesial and distal contact the adjacent teeth and are located at the junction of the occlusal and middle thirds of the crown.
|
|
The labial view of this tooth considers the portion of the tooth visible from the side where the lips would be. The mesial outline of the tooth is straight or slightly convex, whereas the distal outline is much more convex.Maxillary Incisors , hosted by the University of Oklahoma College of Dentistry, accessed on June 8, 2006. Consequently, the height of curvature (the point furthest away from the central axis of the tooth) is closer to the mesioincisal angle on the mesial side while more apical on the distal side.

|
The dental morphology of Vilevolodon is characterized by a dual “mortar-and-pestle” occlusion of molars in which the tallest distal cusp of the upper molar occludes into the deepest distal basin of the opposite, lower molar. The tallest mesial cusp of the lower molar occludes into the mesial basin of the opposite upper molar, simultaneously. Analysis using STL models and tomography scans suggest that this occlusal pattern allows for a complex mechanism of dual crushing and grinding capabilities. A similar occlusal pattern is seen in other Haramiyids, Arboroharamiya and Xianshou.
|
|
There is a creamy white streak located above the eye. The abdomen underside is dirty white, with brown mesial spots. The underside of both wings is brownish-yellow, although darker brown distally. The hindwing upperside is blackish brown.
|
|
Macroglossum phocinum is a moth of the family Sphingidae. It is found in the Solomon Islands. The length of the forewings is about 25 mm. The head and thorax upperside are deep olive green, with a dark mesial stripe.
|
|
Furthermore, the abdomen upperside is similar to that of Manduca rustica, both having three yellow side patches, two rows of white dots and a mesial row of indistinct black dots. The underside of the body has a chalky colour.
|
|
Only multirooted teeth have furcation. Therefore, upper first premolar, maxillary and mandibular molars may be involved. Upper premolars have one buccal and one palatal root. Furcation involvement should be checked from the mesial and the distal aspects of the tooth.
|
|
Macroglossum particrolo is a moth of the family Sphingidae. It is known from India and Sri Lanka. The upper side of the body and forewing is drab grey. The head and thorax upper side has a russet-brown mesial line.
|
|
Sphinx adumbrata is a moth of the family Sphingidae. It is known from Mexico. The thorax upperside, head upperside and palpi are grey. There is a narrow, black mesial line on the abdomen upperside with five elliptical, pale yellow spots.
|
|
The 3 premaxillary, 19 maxillary, and 14 dentary teeth are all thin, curved, and blade-like. There are serrations on the distal (rear) edge of all the teeth, and the maxillary teeth also have serrations on the mesial (front) edge.
|
|
The central groove is not straight but runs down the center of the tooth mesially to distally and contains four pits (mesial, central, central, and distal). The distobuccal groove runs from the distal pit in the central groove distobuccally separating the distal and distobuccal cusps. The lingual groove runs from the more distal of the central pits in the central groove toward the lingual surface between the mesiolingual and distolingual cusps. The buccal groove runs from the more mesial of the central pits in the central groove toward the buccal surface between the mesiobuccal and distobuccal cusps ending in the buccal pit.

Little irregularity index was first written about in his published paper The Irregularity Index: a quantitative score of mandibular anterior alignment. The Littles Irregularity index is generally used by public health sectors and insurance companies to determine the need for treatment and the severity of the malocclusion. It is said that the method is “simple, reliable and valid” of which to measure linear displacement of the tooths contact point. The index is used by creating five linear lines of adjacent contact points starting from mesial of right canine to mesial of left canine and this is recorded.

Assessment of the tooth size – arch length relationship in the mixed dentition determines the presence or absence of any future or existing discrepancy, whether it is crowding or spacing. It involves the prediction of tooth size of the unerupted permanent canines and premolars. A caliper or a fine line divider is used to measure the combined width of teeth in each segment using study models. The circumferential measurement is made on the plaster cast from mesial aspect of first molar on one side to the mesial aspect of the first molar on the opposite side, and this measurement is recorded.

The causes of TLE include mesial temporal sclerosis, traumatic brain injury, brain infections, such as encephalitis and meningitis, hypoxic brain injury, stroke, cerebral tumours, and genetic syndromes. Temporal lobe epilepsy is not the result of psychiatric illness or fragility of the personality.
|
|
The central incisors have fossa on their lingual surfaces. Their mesial and distal proximal contacts are located in the incisal third. The facial and lingual heights of contour are in the cervical third, as is the case with all incisors and canines.
|
|
Studies have demonstrated a tendency for HHV-6 to aggregate in the temporal lobe, with the highest concentrations in astrocytes of the hippocampus. However, one group of researchers ultimately concluded that HHV-6 may not be involved in MTLE related to Mesial Temporal Sclerosis.
|
|
In primitive placental mammals there are four premolars per quadrant, but the most mesial two (closer to the front of the mouth) have been lost in catarrhines (Old World monkeys and apes, including humans). Paleontologists therefore refer to human premolars as Pm3 and Pm4.
|
|
In the lower molars the accessory denticles on the mesial edges are replaced by a deep groove called the reentrant groove. The apical cusp is the primitive protoconid. M2 and M3 are morphologically very similar. M3 is sitting high on the ascending mandibular ramus.
|
|
The buccal surface of each post- canine is smooth. The teeth are also slightly angled so that the posterior of one tooth contacts the anterior of the next. The posterior accessory cusps of teeth 2 and 3 curve upwards towards the top of the tooth. The 4th tooth shows posterior accessory cusps as well as at least one cusp mesial to the main cusp. The 5th tooth only shows one posterior accessory cusp, but the lack of other accessory cusps is “probably due to wear.” The 6th tooth on to the 9th tooth have multiple posterior accessory cusps as well as at least one mesial cusp.
|
|
Maxillary molars have three roots, a mesio-buccal root, disto-buccal root and a palatal root. Thus, check for furcation from buccal, mesio-palatal and disto-palatal aspects. Mandibular molars have one mesial and one distal root, and so, check for involvement from buccal and lingual aspects.
|

Because of the dopaminergic action of the drugs and previous findings from electrode stimulation of the brain (e.g. Bancaud, Brunet-Bourgin, Chauvel, & Halgren, 1994), Taiminen and Jääskeläinen speculate that déjà vu occurs as a result of hyperdopaminergic action in the mesial temporal areas of the brain.
|
|
It is similar in colour to Macroglossum gyrans. The sides of the thorax and legs are dull drab russet. The abdomen underside is without white mesial patches and the underside of the tail is the same colour. The forewing upperside has prominent antemedian black double lines.
|
|
Macroglossum milvus is a moth of the family Sphingidae. It is known from Réunion (formerly known as Île Bourbon) and Mauritius. The head and thorax uppersides have a dark mesial line. The abdomen upperside has four orange lateral patches, of which the first is the smallest.

His research is centered on the use of Magnetic Resonance Imaging and its applications to epilepsy and on unraveling the major developmental brain malformations in epilepsy. He was the first to recognize and prove that mesial temporal sclerosis, a common cause for difficult epilepsy, can be identified with MRI.

Eusthenodon possesses a small parasymphysial plate attached to the splenial via the small attachment of the plate onto the anterior portion of the mesial lamina. The shape and size of the parasymphysial plate exhibited in Eusthenodon is present in all tristichopterids and is a diagnostic characteristic of the family.
|
|
The abdomen upperside has small yellow spots. The underside of the palpus, middle of the thorax and mesial patches of the abdomen are white and the side tufts of the abdomen are white-tipped. The forewing upperside is slightly variable. Both wings undersides are grey at the extreme base.
|
|
The thorax underside, the legs, the greater part of the first abdominal sternite and the mesial spot on the second and third are creamy. Both wing undersides are maize-coloured at the extreme base, otherwise coloured like the upperside of the hindwing. The hindwing upperside is chestnut-red.
|
|
The abdomen upperside has one yellow lateral patch. The underside of the palpus, middle of the thorax and the mesial abdominal patches are all greyish white. The sides of the thorax, legs and abdomen are deep brown. The forewing upperside has a basal area shaded with reddish grey.

The collar with a thin, almost white, transverse line. The abdomen upperside has a series of small mesial dots and a longitudinal lateral band that are brownish black, and two widely separated rows of whitish dorsal dots. The body underside is grey. The forewing upperside is grey with brownish black markings.
|
|
The species was thought to have lived 6.1 to 5.7 million years ago. Fossil remains have provided very important information regarding dental morphology. Orrorin had smaller teeth relative to body size and the enamel was thicker. The upper canines contain a mesial groove which differs from both Australopithecus and Ardipithecus.
|
|
L. phyllis Christ. (81 g). Male above sea-green, with a silvery silky gloss; female dark brown, with a distinct discocellular spot on the forewing. On the underside both sexes have a very sharply defined conspicuous mesial streak which extends from the base across some ocelli to the outer margin.
|
|
Occasionally they are congenitally missing. From a facial aspect, maxillary canines are approximately one millimetre narrower than the central incisor. Their mesial aspects resemble the adjacent lateral incisors, while their distal aspects anticipate the first premolars. They are slightly darker and more yellow in color than the other anterior teeth.
|
|
The blue arrow, which indicates a mesial direction, applies to the opposite side as well up until the green line. The red arrow is directly buccal to the right first maxillary molar, and the name label for the patient (Martin) is embedded in the resin directly palatal to the same tooth.
|
|
In 2007, David B. Norman and colleagues regarded this as unfounded. They instead found Tatisaurus to be a dubious basal thyreophoran, showing a single thyreophorean synapomorphy; a ventrally deflected mesial end of the dentary. If considered a thyreophoran, it would be one of the oldest known members of the group.

Celebochoerus cagayanensis is an extinct species of suid in the genus Celebochoerus. The first fossil specimen was discovered in 2016 in the Philippines. It differs from the Sulawesi species Celebochoerus heekereni in that it has mesial and distal enamel bands on its upper canines. It also has huge upper tusks.
|
|
Reelin In the mid 1980s, human herpesvirus 6 (HHV-6) was suggested as a possible causal link between febrile convulsions and mesial temporal lobe epilepsy. However, although the virus is found in temporal lobe tissue at surgery for TLE, it has not been recognised as a major factor in febrile seizures or TLE.
|
|
Compared to the tooth's mesial view of the cervical line, the distal cervical line is slightly more cervical by close to a millimeter. There may be a developmental groove present for all or most of the length. The distal view of the lateral incisor fits into the geometric shape of a triangle.
|
|
The teeth of Crosbysaurus are triangular in outline with serrations on both edges. Almost all specimens have "compound denticles"; serrations with their own subdivisions. The serrations on the trailing (posterior/distal) edge of the tooth are always larger than the leading (anterior/mesial) edge. The teeth are small, approximately 3-5 millimeters tall.

A powerfully built insect with strong neuration in the forewing. The frons is either quite black or bears a yellow mesial line, never a yellow lateral streak along the eye. The antennae are long, yellow, with thin club; the frons has a yellow mesial stripe, the breast is diagonally streaked with yellow, the abdomen is for the most part yellow, the costal margin of the forewing is not dentate, the cell of the forewing is broad and the hindwing is rounded, without a tail. The spots of the forewing orange, the marginal ones yellow; hindwing orange, a marginal band enclosing a yellow submarginal spot, a basal subcostal area, a patch in the extremity of the cell, as well as several spots on the disc, black.
|
|
Its antenna shows a basicerite bearing an acute, ventrolateral tooth. Its mouthparts are the same as for Alpheus tricolor: its incisor process bearing less than 10 teeth. The epipodial plate on the coxa of its third maxilliped bears thick, blunt setae. Its merus is slightly crenellated on the mesial margin, and contains no teeth.

Macroglossum aesalon is a moth of the family Sphingidae first described by Paul Mabille in 1879. It is known from Madagascar, Mauritius and the Comoro Islands. The abdomen upperside has four orange lateral patches, the first and fourth generally small. There is also a black mesial spot at the base of the anal brush.
|
|
This often results in posterior open bite in patients mouth who have primary failure of eruption. This phenomenon can occur in any quadrant of the mouth. There are two types of primary failure of eruption. Type I involves failure of eruption of teeth distal to the most mesial affected tooth to be all same.
|

Underside somewhat paler brown than upper, with distinct ocelli, but no basal ocelli on the forewing. In South-East Europe, from Hungary and Galicia through the Balkan Peninsula and Asia Minor to Mesopotamia; also in Spain. — ripartii Frr. (81 f), has on the hindwing below a white mesial streak which extends from the base to the outer margin.

Cytosolic acyl coenzyme A thioester hydrolase is an enzyme that in humans is encoded by the ACOT7 gene. This gene encodes a member of the acyl coenzyme family. The encoded protein hydrolyzes the CoA thioester of palmitoyl-CoA and other long-chain fatty acids. Decreased expression of this gene may be associated with mesial temporal lobe epilepsy.
|
|
It eats lizards, small mammals and large insects. The adult has a grey head, breast and neck, white throat, black moustaches and mesial stripes, brown back and upperwings, and brown bars on white underparts and underwings. The juvenile is brown and mottled above, pale below with brown streaks, and has a broad white supercilium and brown face.

Raymunida insulata is a species of squat lobster in the family Munididae from the Pacific and Indian oceans. The species can be distinguished by its morphology (subtle morphological characteristics, such as length of the mesial spine on the basal antennal segment, the length of its walking legs, and color pattern) and its mitochondrial cytochrome c oxidase subunit I sequences.
|
|
Macroglossum calescens is a moth of the family Sphingidae. It is known from Papua New Guinea. The head upperside is dark grey with a blackish mesial stripe and a distinct white line above the eye. The thorax and abdomen uppersides are black with a chestnut tint, although the anterior part of the thorax is speckled with white tipped scales.
|
|
The head and thorax uppersides have no dark mesial stripe. The underside of the palpus and middle of the thorax are dirty grey, the white scaling mixed with drab-brown scales, the sides darker. The abdomen underside is grey. Both wing undersides are dark walnut-brown, dull, becoming somewhat olive distally, without a distinct brown border.
|
|
The mesial margin of some of its teeth have a pronounced distal curvature. Additionally, its palatines are strongly convex with a pronounced ridge along the midline. In palatal view, the palatine width narrows anteriorly from the suborbital fenestrae to the midline, in a distinct elongate triangular shape. The maxillopalatine suture midline terminus is level to the fourth maxillary alveolus.
|
|
The distal and mesial marginal ridges are evident and the cingulum is prominent. The lingual fossa is more concave than the central incisor. The cingulum will often have a deep developmental groove on the distal side that can continue well into the root. The lingual view of the lateral incisor fits into the geometric shape of a trapezoid.
|
|
The mandibular central incisor is the tooth located on the jaw, adjacent to the midline of the face. It is mesial (toward the midline of the face) from both mandibular lateral incisors. As with all incisors, its function includes shearing or cutting food during mastication, commonly known as chewing. There are no cusps on the tooth.
|
|
The females are slightly larger. The mesial stripe on the throat is dark but narrow. In flight the male seen from below shows a light wing lining (underwing coverts) and has blackish wing tips. When seen from above the tail bands are faintly marked on the lateral tail feathers and not as strongly marked as in the Eurasian sparrowhawk.

|
Usually used for treatment of adolescent patients who will require a more permanent design once they are fully grown. The lifespan of a composite veneer is approximately 4 years. In contrast, a porcelain veneer may only be indirectly fabricated. A full veneer crown is described as "a restoration that covers all the coronal tooth surfaces (Mesial, Distal, Facial, Lingual and Occlusal)".
|
|
It is larger than the neighboring lateral incisor and is usually not as convex on its labial surface. As a result, the central incisor appears to be more rectangular or square in shape. The mesial incisal angle is sharper than the distal incisal angle. When this tooth is newly erupted into the mouth, the incisal edges have three rounded features called mammelons.

Transpalatal arch or TPA may also be used as an adjunct in keeping anchorage in an extraction treatment in Orthodontics. A paper by Zablocki et al. showed negligible statistically significant difference between patients who received TPA vs patients who don't receive TPA. However, many other papers have showed that TPA cannot provider absolute anchorage to prevent any mesial movement of the posterior molar.

The permanent maxillary central incisor is the widest tooth mesiodistally in comparison to any other anterior tooth. It is larger than the neighboring lateral incisor and is usually not as convex on its labial surface. As a result, the central incisor appears to be more rectangular or square in shape. The mesial incisal angle is sharper than the distal incisal angle.

It differs from most similar species Dolbina exacta by the presence of large black patches and extremely small black dots on the underside of the abdomen. The main distinguishing character however, is the presence of a crescent hook on the aedeagus apex. The abdomen and wings undersides are brownish grey. There are large black mesial patches on the abdomen underside.

The squid are a reddish orange colour with a large complement of chromatophores. The suckers of the arms possess blunt teeth. On the meaty ends (clubs) of the tentacles, there are four rows of suckers; the inner two (mesial) rows are three times as large as the outer two (marginal) rows. The larger suckers have horny rings with up to 45 teeth.

Adequate running room is necessary to allow the implant-supported crown to exhibit a tooth-shaped contour despite the smaller diameter and circular nature of implant platforms.Smith RB, Tarnow DP. _Classification of molar extraction sites for immediate dental implant placement: technical note_. Int J Oral Maxillofac Impl 2013;28:911-916 For example, the mean mesial-distal dimension of a maxillary central incisor at the points at which it contacts the adjacent teeth is 8.6 mm, and the mean mesial-distal dimension of the same tooth at the cementoenamel junction (CEJ) is 6.4 mm.Scheid RC, Woelfel JB. Woelfel's Dental Anatomy: its relevance to dentistry, Lippincott Williams & Wilkins, 2007 Even though the implant diameter chosen for the maxillary central incisor is usually around 4-5 mm, the supragingival tooth contours need to mimic those of the natural tooth if esthetic success is intended.

Its third maxilliped counts with an epipodial plate bearing thick setae, while its first chelipeds are found with their merus bearing a strong disto-mesial tooth; its third pereiopod has an armed ischium, with a simple and conical dactylus. Its telson is broad, distally tapering, with 2 pairs of dorsal spines. The species is named after its characteristic colour pattern, including white, red and orange.Anker, Arthur.

BPOP is located in the parasagittal and mesial regions of the parieto-occipital cortex. This form has been associated with IQ scores that range from average intelligence to mild mental retardation, seizures, and cognitive slowing. The age of seizure onset has been found to occur anywhere from 20 months to 15 years, and in most cases the seizures were intractable (meaning hard to control).

The radix entomolaris is an additional root in human's mandibular molar teeth. The human mandibular teeth have two roots usually. In rare cases, however, a root may develop between the distal and the mesial roots which is called entomolaris, if it is located lingual to the tooth. Such a phenomenon is named radix paramolaris in case an extra root is buccal to a molar tooth.
|
|
On the lingual side, two long furrows are visible, and on the buccal side breakage exposes three long infundibula, of which the most mesial one is the longest and the most distal one the shortest. In the occlusal surface, these three infundibula merge into a single islet. In addition, three dentine lakes are visible in the occlusal surface, which has dimensions of 4.58 × at least 2.52 mm.

|
The upper molars extend onto the zygomatic arch and are considerably smaller than their neighbouring premolars. Like P4, their distal root is wider than the mesial and formed by the fusion of two roots. The profiles of the molars are more rounded than those of the premolars. Similar to the upper incisors, the lower incisors are simple conical teeth curved distally and aligned with the cheek teeth.
|
|
The front teeth, including the first maxillary teeth, do not have serrations. Teeth in the middle of the dentary are more strongly recurved and possess serrated rear edges. At the rear of the dentary, the teeth are short and stout with serrations on both, mesial and distal, edges. Caihong probably has ten neck vertebrae, thirteen back vertebrae, five sacral vertebrae and twenty-sic tail vertebrae.

Adjacent areas of the body are represented by adjacent areas in the cortex. When body parts are drawn in proportion to the density of their innervation, the result is a "little man": the cortical homunculus. Many textbooks have reproduced the outdated Penfield-Rasmussen diagram [ref?], with the toes and genitals on the mesial surface of the cortex when they are actually represented on the convexity.

Adults are pale dusty ochreous, the costa of the forewings broadly washed with blackish brown, absorbing the rather large dark discal spots. There is an exterior dotted line and a terminal series of blackish dots. The hindwings have a terminal dotted line before the fringes and an extra mesial dotted line, as well as a discal dot.The Canadian Entomologist Vol 13 Adults are on wing from June to September.

Viewed from the buccal the buccal cusp is centered over the root as in the three cusp variety. Viewed from the mesial or distal its heights of contour are similar to the three cusp variety. Sometimes, premolars are referred to as bicuspids. Even though the terms are synonymous, "bicuspid" refers to having two functional cusps, and the mandibular second premolar is an example of a premolar with three functional cusps.

The rostrum (beak) is acuminate and has lateral spines. It has a closed areola (the hourglass shaped lines on the back). It is very similar to Faxonius difficilis but has a central projection that is longer and more curved, with a more smoothly curved expanded mesial process. It can be distinguished from F. palmeri by its shorter gonopods (which may reach the third coxa) and a shorter and stouter central projection.

Individuals with schizophrenia, as well as patients being successfully reconditioned with quetiapine for blunted affect, show activation of the prefrontal cortex (PFC). Failure to activate the PFC is possibly involved in impaired emotional processing in individuals with schizophrenia with blunted affect. The mesial PFC is activated in aver individuals in response to external emotional stimuli. This structure possibly receives information from the limbic structures to regulate emotional experiences and behavior.

It includes assessment of tooth mass, arch form, arch length, skeletal pattern, skeletal growth potential, orofacial musculature, facial aesthetics, oral habits and hereditary assessment of parents and siblings. The most favorable morphologic factors for serial extraction include class 1 malocclusion, a favorable morphogenetic pattern – one that does not change, a flush terminal plane or a mesial step relationship of the primary second molars, minimum overjet and minimum overbite.

Gingivitis is a category of periodontal disease in which there is no loss of bone but inflammation and bleeding are present. Each tooth is divided into four gingival units (mesial, distal, buccal, and lingual) and given a score from 0–3 based on the gingival index. The four scores are then averaged to give each tooth a single score. The diagnosis of the periodontal disease gingivitis is done by a dentist.

Damage to the frontal lobe has been related to changes in personality. The frontal lobes are crucial for the development of personality, sense of self, and humor development. Anatomically, there are meaningful connections between the frontal lobes (specifically the polar and ventral/medial areas) and other brain regions related to affective-emotional responses. Early cases of witzelsucht observed damage to the mesial-orbital region of the frontal lobe.

The occlusal table (the area bounded by the cusps, cusp ridges, and marginal ridges) is rectangular. The groove pattern is shaped like a “Y” with the tail pointed to the lingual and placed between the distolingual and mesiolingual cusps one third of the distance form the distal to the mesial. The contacts with the adjacent teeth are positioned buccal to the midpoint. Viewed from the buccal the buccal cusp tip is centered mesiodistally.

21, 9856. In addition, the ability of individuals with AN to activate remote memories, learn new information, plan ahead, regulate actions according to environmental stimuli, and shift behavioural sets appropriately are all implicated. Some individuals with anorexia nervosa (AN) have an inability to change their pattern response behaviours, which has been linked to disturbances found in the cortical and subgenual cingulate - mesial temporal pathways of these individuals.Kaye, W.H., Frank, G.K., Bailer, U.F., & Henry, S.E. (2005).

L. damone Ev. (81 h). At once distinguished from damon by the quite different tint of the blue in the male: the name-typical form, moreover, has a narrow black border. The white mesial streak of the hindwing beneath is either absent or present, but in the latter case is mostly much less conspicuous, diffuse, obsolescent or shortened. Female above dark brown, usually with obsolescent reddish yellow submarginal spots on the hindwing.

This option also negates the risks and costs that comes with prosthodontic treatment and the impression that there is no missing tooth. Some factors need to be considered when making a decision whether to undergo space closure. These include facial profile, size and dimension of canine, the shade of colour of the teeth and the gingival contour and height. Group function occlusion is usually present as a result of the mesial movement of the canine.

|
The cingulum reaches incisally a great length and is large enough to create small fossa on either side of it. Depicted by the cementoenamel junction, the cervical line is the border between the root and crown of a tooth. On the mesial and distal surfaces, the cervical line curves incisally, which is also seen in the permanent maxillary central incisor. The root of this tooth is cone-shaped with a rounded apex.
|
|
The maxillary central incisor is a human tooth in the front upper jaw, or maxilla, and is usually the most visible of all teeth in the mouth. It is located mesial (closer to the midline of the face) to the maxillary lateral incisor. As with all incisors, their function is for shearing or cutting food during mastication (chewing). There is typically a single cusp on each tooth, called an incisal ridge or incisal edge.

Adult, note the pale appearance to the median upperwing coverts This slim and small hawk is easily identified by its white iris and the white throat and dark mesial stripe. A white spot is sometimes visible on the back of the head. When perched, the wing tip nearly reaches the tip of the tail. The ceres are distinctly yellow and the head is dark with the underside of the body darkly barred.

The mesial band is broad, brownish filled and black edged, the edge lines straight, the inner angled on the submedian, the outer at vein 4, curved below. The inner half of the median band is more strongly dark-filled than the outer, intensified on the submedian fold. There is a dark diffused shade on the margin, touching the projection of the median band. The hindwings are whitish, with a grey discal point and terminal border.Insec. Insc. Mens.

The also reported anchorage loss when the anterior teeth moved mesially by the 1.8-mm anterior movement of the upper first premolars, with a mesial tipping of 1.5°. Both the abovementioned studies, observed slight maxillary first molars intruded and slight first premolars extrusion. This study also saw increase of lower anterior facial height by 2.2 mm but they found no significant difference in lower anterior facial height increase between patients of high, neutral, or low mandibular plane angles.
|
|
The mandibular second premolar is the tooth located distally (away from the midline of the face) from both the mandibular first premolars of the mouth but mesial (toward the midline of the face) from both mandibular first molars. The function of this premolar is assist the mandibular first molar during mastication, commonly known as chewing. Mandibular second premolars have three cusps. There is one large cusp on the buccal side (closest to the cheek) of the tooth.
|
|
Surfaces nearest the junction of the crown and root are referred to as cervical, and those closest to the apex of the root are referred to as apical. The tissue surrounding apex is called periapical. Mesial signifies a surface closer to the median line of the face, which is located on a vertical axis between the eyes, down the nose, and between the contact of the central incisors. Surfaces further away from the median line are described as distal.

A permanent maxillary central incisor The maxillary central incisors are usually the most visible teeth, since they are the top center two teeth in the front of a mouth, and they are located mesial to the maxillary lateral incisor. The overall length of the deciduous maxillary central incisor is 16 mm on average, with the crown being 6 mm and the root being 10 mm.Ash, Major M. and Stanley J. Nelson.

In the lower molars, the talonid is situated in front of the trigonid, such a unique dental form is distinct from the typical tribosphenic pattern. In this "pseudotribosphenic" trait, the mesial cingulid is expanded to form a pseudotalonid, and its distal talonid is underdeveloped. It shares with Australosphenida a thin, slender lower jaw but differs from the non-monotreme Ausktribosphenida by having more developed postdentary trough. Its dental formula has been reconstructed as: p4, m3 (four premolars, three molars).

The lamella of its scaphocerite is not reduced. Its third maxilliped counts with an epipodial plate bearing thick setae, while its first chelipeds are found with their merus bearing a strong disto-mesial tooth; its third pereiopod has an armed ischium, with a simple and conical dactylus. Its telson is broad, distally tapering, with 2 pairs of dorsal spines. The species is named after Frédéric Fasquel, a photographer who contributed rare shrimp specimens for the Muséum national d'histoire naturelle.

The palatal view of this tooth considers the portion of the tooth visible from the side where the tongue would be. The palatal side of the maxillary central incisor has a small convexity, called a cingulum near the cervical line and has a large concavity, called the lingual fossa. Along the mesial and distal sides are slightly raised portions called marginal ridges. The lingual incisal edge is also raised slightly to the level of the marginal ridges.

The type species, D. amazighi, is known from the Ksar Metlili Formation in the Atlas Mountains, dating to the Berriasian. It is known from several molars, about 1.85 mm long. These teeth are noted for being rather high and narrow crowned, bearing three main cusps that decrease in height posteriorly, as well as two minuscule mesial cusps. D. indicus is known from a single lower molar tooth from the Kota Formation, dating to the Hettangian-Pliensbachian.

This reactivation has been associated with many clinical manifestations. Reactivation can occur in locations throughout the body, including the brain, lungs, heart, kidney and gastrointestinal tract. In some cases, HHV-6 reactivation in the brain tissue can cause cognitive dysfunction, permanent disability and death. A growing number of studies also suggest that HHV-6 may play a role in a subset of patients with chronic neurological conditions such as multiple sclerosis, mesial temporal lobe epilepsy, status epilepticus and chronic fatigue syndrome.

Bone loss from aggressive periodontitis that led to an exposed furcation on an upper molar. In health, the bone exists about a millimeter and a half away from the cementoenamel junction, which is the line that separates the crown from the root trunk (the line can be seen clearly in the photo). mesial vertical defect on the same tooth. The bent "stick" on the left of the tooth is a piece of gutta percha being used to trace the defect.

294, BYU 9438 and BYU 13068 are indeed pedal unguals. This suggestion was confirmed by Senter in 2007. According to Kirkland et al. in 1993, Utahraptor can be recognised by the following autapomorphies: claws on the hand that are more specialized as cutting blades than in other dromaeosaurids; a lacrimal bone with distinctly parallel mesial and outer sides, giving it an elongate subrectangular appearance in top view; and a base of nasal opening on the premaxilla parallel to the premaxillary tooth row.

This included reduction of the buccal cusp in the upper teeth and the lingual cusp of lower teeth in the frontal plane. Additionally, on the sagittal plane reductions are made on the mesial cusp for upper teeth and distal cusp of the lower teeth. Schuler developed this rule on an articulator whose movement is converse to the natural mandibular movement. One of the key factors in establishing the balanced occlusion is the assumption that condylar guidance of the patient is constant or fixed.

The manus is moderately broad and its breadth is equal to its length. The dorsum is slightly convex longitudinally, strongly convex laterally, with teeth in the middle continuing onto the distal half. The carpus (third segment from the distal end of the leg) bears a large, broad, hook-shaped mesial spine (missing on left cheliped). The angle of the distoventral or ventromesial condyle (a heavily sclerotized projection of the mandible's dorsal surface) is not produced into a spine or tubercle.

The mandibular first premolar is the tooth located laterally (away from the midline of the face) from both the mandibular canines of the mouth but mesial (toward the midline of the face) from both mandibular second premolars. The function of this premolar is similar to that of canines in regard to tearing being the principal action during mastication, commonly known as chewing. Mandibular first premolars have two cusps. The one large and sharp is located on the buccal side (closest to the cheek) of the tooth.

Vertical strokes are used on the anterior regions of the mouth and on the distal and mesial surfaces of the posterior teeth, while oblique strokes are used on the facial and lingual surfaces of the posterior teeth. When working on the line angles of posterior teeth and the midlines of the facial or lingual surfaces of anterior teeth, horizontal strokes are used. The number of strokes should be limited to areas where calculus is present as to minimize stress to the muscles of the hand.

The tooth at the end of each region was less genetically stable and hence more prone to absence. In contrast, the tooth most mesial in each region seemed to be more genetically stable. A subsequent theory hypothesised the teeth at the end of each region were possibly “vestigial bodies” that became obsolete during the evolutionary process. At present, it has been theorised that evolutionary change is working to decrease the human dentition by the loss of an incisor, premolar and molar in each quadrant.

The use of veneers can also be used instead of composite however, these are more expensive and more time consuming. There have been several studies which showed the advantages of orthodontic space closure without prosthodontic space replacements. The main advantage mentioned is the early completion of the treatment during early adolescence and the long lasting result of the treatment outcome. In individuals with a high smile line, the mesial re-positioning of canine maintains the normal soft tissue architecture is important in maintaining the aesthetic appearance.

The interdental plate refers to the bone-filled mesial-distal region between the teeth. The word "interdental" is a combination of "inter" + "dental" (meaning "between the teeth") which originated in approximately 1870. In paleobiology, the presence or absence of the interdental plate can determine the place of an animal in the evolutionary scale, and paleontologists use the interdental plate when trying to classify a new specimen. Thecodont reptiles and theropod dinosaur fossils have an interdental plate, whereas acrodont reptiles such as Sphenodontia do not.

The height of contours have great functions to oral cavity # They allow the food to be deflected allowing proper degree of massage to the gingiva # They prevent the food of being accumulated at the tooth # Holding the gingiva under definite tension #Protection of the gingiva surrounding the tooth #Formation of a contact point between teeth, where the mesial and distal surfaces of adjacent teeth meet The height of contour must be replicated in restorative dental work to serve the functions that a natural contour would provide.

Cortical bone is known to resorb slower than the medullary bone. Therefore, cortical anchorage is used in orthodontics to allow for slower movement of teeth, especially molars in the posterior dentition. A clinician may produce a movement which allows the buccal roots of the permanent molars to move buccally (outside), eventually contacting the cortical bone. It is claimed that by using cortical bone against posterior teeth, mesial movement of posterior teeth can be prevented which helps in anchoring the posterior teeth in the back of the jaw.
|
|
Type II involves a greater eruption pattern, not complete, among the teeth distal to the most mesial affected tooth. It is difficult to diagnose between these two types of failure of eruption because 2nd molar does not erupt until a patient is 15 years of age. Plenty of times, patient's receive orthodontic care much before they turn 15 years old. Therefore, to properly diagnose between two types, a patient needs to be over 15 and a definitive proof of uneruption of 2nd molar is required.

The white-eyed buzzard (Butastur teesa) is a medium-sized hawk, distinct from the true buzzards in the genus Buteo, found in South Asia. Adults have a rufous tail, a distinctive white iris, and a white throat bearing a dark mesial stripe bordered. The head is brown and the median coverts of the upper wing are pale. They lack the typical carpal patches on the underside of the wings seen in true buzzards, but the entire wing lining appears dark in contrast to the flight feathers.

Accompanying the onset of epilepsies is hippocampal sclerosis, also known as Ammon's horn sclerosis. Individuals afflicted suffer unilateral volume loss, as evidenced by MRI scans.Johns, P., Thom, M. (2008) Epilepsy and hippocampal sclerosis: cause or effect? Neuropathology Article, 8, 16-18 Hippocampal sclerosis involves neural loss and a selective mesial temporal sclerosis (MTS) danger and is likely caused by an overactivation of N-methyl-D-aspartate (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors by the surplus signaling of excitatory neurotransmitters.

Molar distalization is a process in the field of Orthodontics which is used to move molar teeth, especially permanent first molars, distally (backwards) in an arch. This procedure is often used in treatment of patients who have Class 2 malocclusion. The cause is often the result of loss of E space in an arch due to early loss of primary molar teeth and mesial (forward) migration of the molar teeth. Sometimes molars are distalized to make space for other impacted teeth, such as premolars or canines, in the mouth.

Musicogenic seizures are generally defined as a focal seizure, as the lateral and mesial temporal, and orbitofrontal areas of the brain are affected. Musicogenic seizures have complex stimuli due to the broad scope of possibilities of triggers. A wide spectrum of triggers has been noted to stimulate musicogenic seizures and musicogenic epilepsy as the type of music and method of perceiving music varies from one patient to another. It has been reported that 17% of music-evoked seizures are induced solely by music, while 53% are induced by miscellaneous musical stimuli.

Ruben Kuzniecky, M.D. is Vice-chair academic affairs and professor of neurology at Northwell Health specializing in the field of epilepsy, epilepsy surgery and neuro-imaging. He was one of the first to recognize and prove that mesial temporal sclerosis, a common cause for difficulty in controlling temporal lobe epilepsy, can be identified with MRI scans. He also described the Kuzniecky Syndrome in 1991, also known as perisylvian polymicrogyria. The syndrome is characterized by seizures, cognitive abnormalities, and a peculiar inability to use the mouth and tongue muscles.

Ettinger animals models carried inferotemporal or latero-ventral prestriate ablation. In 1966 George Ettlinger, together with the psychologist Colin Blakemore and the neurosurgeon Murray Falconer, described the results of a study on correlation between pre- operative intelligence and the severity of mesial temporal sclerosis in temporal lobe specimens excised to treat intractable epilepsy. Such study It is known as a forerunner of what has become one of the potentially most interesting techniques for exploring the relationship between certain aspects of human memory and temporal lobe structures.Oxbury, J. M., & Oxbury, S. (1998).

It is evident that its expression depends on neural paths arising in close association with the telencephalic and diencephalic centers concerned with respiration. Wilson considered the mechanism to be in the region of the mesial thalamus, hypothalamus, and subthalamus. Kelly and co-workers, in turn, postulated that the tegmentum near the periaqueductal grey contains the integrating mechanism for emotional expression. Thus, supranuclear pathways, including those from the limbic system that Papez hypothesised to mediate emotional expressions such as laughter, probably come into synaptic relation in the reticular core of the brain stem.

Eruption typically occurs between the ages of nine and ten years of age. From a facial aspect, the mandibular canine is notably narrower mesiodistally than the maxillary one, even though the root may be just as long (and at times bifurcated). A distinctive feature is the nearly straight outline this tooth has compared to the maxillary canine which is slightly more bowed. As in the maxillary canine, the mesial incisal edge (or cusp ridge) is shorter than the distal side, however, the cusp is displaced slightly lingual relative to the cusp of the maxillary canine.
|
|
The distal outline of the crown is more convex than the mesial outline, and the distoincisal angle is not as sharp as the mesoincisal angle. After the mammelons are worn away, the incisal edge of the maxillary central incisor is straight mesiodistally. The center of the incisal edge curves slightly downward in the center of the tooth. The cervical line, which is seen as the border between the crown and the root of the tooth, is closer to the apex of the root in the center of the tooth.

The 20 specimens found as of 2007 include: the posterior part of a mandible in two pieces; a symphysis and several isolated teeth; three fragments of femora; a partial humerus; a proximal phalanx; and a distal thumb phalanx. Orrorin had small teeth relative to its body size. Its dentition differs from that found in Australopithecus in that its cheek teeth are smaller and less elongated mesiodistally and from Ardipithecus in that its enamel is thicker. The dentition differs from both these species in the presence of a mesial groove on the upper canines.

The maxillary second molar is the tooth located distally (away from the midline of the face) from both the maxillary first molars of the mouth but mesial (toward the midline of the face) from both maxillary third molars. This is true only in permanent teeth. In deciduous (baby) teeth, the maxillary second molar is the last tooth in the mouth and does not have a third molar behind it. The function of this molar is similar to that of all molars in regard to grinding being the principal action during mastication, commonly known as chewing.

There are slow spindles in the range of 11 – 13 Hz that are associated with increased activity in the superior frontal gyrus, and fast spindles in the range of 13 – 15 Hz that are associated with recruitment of sensorimotor processing cortical regions, as well as recruitment of the mesial frontal cortex and hippocampus. There is no clear answer as to what these sleep spindles mean, but ongoing research hopes to illuminate their function. K-complexes are single long delta waves that last for only a second. They are also unique to NREM sleep.

After all of the decay had been removed, (D), the pulp chamber had been exposed and most of the mesial half of the crown was either missing or poorly supported. It is possible for both tooth decay and periodontal disease to be missed during a clinical exam, and radiographic evaluation of the dental and periodontal tissues is a critical segment of the comprehensive oral examination. The photographic montage at right depicts a situation in which extensive decay had been overlooked by a number of dentists prior to radiographic evaluation.

|
When pulp testing results are inconclusive and that patients cannot localise or specify the pain or symptoms, an anaesthetic would be helpful and be used. The most posterior tooth in the area where the pain resonates undergoes anaesthesia by either infiltration or intraligamentary injection until pain diminishes. If the pain is still present, the procedure is repeated on the mesial teeth, one by one until the pain diminishes and is gone. If one can still not determine the source of the pain, the procedure will be repeated on the opposite arch.

Decreased reelin expression in the hippocampal tissue samples from patients with temporal lobe epilepsy was found to be directly correlated with the extent of granule cell dispersion (GCD), a major feature of the disease that is noted in 45%–73% of patients. The dispersion, according to a small study, is associated with the RELN promoter hypermethylation. According to one study, prolonged seizures in a rat model of mesial temporal lobe epilepsy have led to the loss of reelin-expressing interneurons and subsequent ectopic chain migration and aberrant integration of newborn dentate granule cells. Without reelin, the chain-migrating neuroblasts failed to detach properly.

Various teeth of Razanandrongobe; wear patterns marked as ws In 2006, Maganuco and colleagues analyzed wear patterns on the surface of Razanandrongobes teeth. For the teeth at the sides of the jaw, most of the wear is present on the outer (lingual) surface of the teeth, on which a U-shaped chip is present on the top third of the crown. There is also a thinner chip on the front (mesial) edge of the tooth, flattening some of the serrations. By contrast, for the teeth at the front of the jaw, the wear is more present on the inner (labial) surface.

It was initially believed to be a coelurosaur due to the upturned anterior process of the postorbital as well as specialized teeth which are unserrated on the mesial (front) side and have an 8-shaped cross section, similar to those of dromaeosaurids and compsognathids. However, many other features contradict those of these families and other coelurosaurs, so its original describers were unable to conclusively assign it to any specific family. They did note its similarity to a then-undescribed Patagonian theropod now known as Murusraptor. More recent analyses have explained that these coelurosaur-like traits are also present in some megaraptorans.

However surgery for PTE may be more difficult than it is for epilepsy due to other causes, and is less likely to be helpful in PTE than in other forms of epilepsy. It can be particularly difficult in PTE to localize the epileptic focus, in part because TBI may affect diffuse areas of the brain. Difficulty locating the seizure focus is seen as a deterrent to surgery. However, for people with sclerosis in the mesial temporal lobe (in the inner aspect of the temporal lobe), who comprise about one third of people with intractable PTE, surgery is likely to have good outcome.

The occlusal surface is oval. The tooth is 6 mm high and Wilson and colleagues estimate that the occlusal surface is 2.5 × 1.8 mm, close to the dimensions of GSI/SR/PAL-G070. They suggest the tooth probably had enamel on all sides of the crown, but Prasad and colleagues point to a possible enamel-dentine junction on the damaged side as evidence that enamel may be absent there. GSI/SR/PAL-G059, identified as a left mf3, has a height of 5.97 mm at the mesial side, but only 2.02 mm at the distal side because of curvature.

The foramen ovale is used as the entry point into the skull when conducting a Percutaneous Stereotactic Rhizotomy, a type of radiofrequency ablation performed to treat trigeminal neuralgia. In the procedure, the electrode is introduced through the cheek of an anesthetized patient and radiologically guided into the foramen ovale, with the intention of partially or fully ablating one or more of the divisions (typically the Mandibular) to relieve pain. This entry point is also used to surgically place local electrodes directly on the surface of the mesial temporal lobe, in order to observe neural activity of patients with suspected focal epilepsy.

The model also proposes a developmental component of bipolar disorder, wherein limbic abnormalities are present early on, but rostral prefrontal abnormalities develop later in the course. The importance of limbic dysfunction early in development is highlighted by the observation that amygdala lesions early in adulthood produce emotional abnormalities that are not present in people who develop amygdala damage in adulthood. Lateralized seizure sequelae similar to bipolar has been reported in people with mesial temporal lobe seizures, and provides support for kindling hypotheses about bipolar. This observation led to the first experiments with anticonvulsants in bipolar, which are effective in stabilizing mood.

Structurally, secondary mania is associated with destructive lesions that tend to occur in the right hemisphere, particularly the frontal cortex, mesial temporal lobe and basal ganglia. Functionally hyperactivity in the left basal ganglia and subcortical structures, and hypoactivity in the right ventral prefrontal and basotemporal cortex have been reported in cases of secondary mania. The destruction of right hemisphere or frontal areas is hypothesized to lead to a shift to excessive left sided or subcortical reward processing. John O. Brooks III put forward a model of bipolar disorder involving dysregulation of a circuit called the "corticolimbic system".

Amino acid changes in MT-ND4, MT-ND5 and MT-ATP8 resulting from mutations at the 11994, 8502 and 13,231 bp of mtDNA are significantly correlated in mesial temporal lobe epilepsy (MTLE) patients with hippocampal sclerosis. The 11994 C>T mutation to the MT-ND4 gene results in a Thr to Ile shift at the 412 position. Genome analysis has never been used in MTLE cases and could provide another diagnostic method in the disease. MT-ND4 is downregulated in cystic fibrosis, a disease that results from mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) channel.

The root is single, but longer and thicker than that of the incisors, conical in form, compressed laterally, and marked by a slight groove on each side. The lingual surface also presents two depressions on either side of the surface separated by a ridge in between; these depressions are known as mesial and distal lingual fossae. In humans, the upper canine teeth (popularly called eye teeth, from their position under the eyes) are larger and longer than the lower, and usually present a distinct basal ridge. Eruption typically occurs between the ages of eleven and twelve years.

The maxillary first premolar is one of two teeth located in the upper jaw, laterally (away from the midline of the face) from both the maxillary canines of the mouth but mesial (toward the midline of the face) from both maxillary second premolars. The function of this premolar is similar to that of canines in regard to tearing being the principal action during mastication, commonly known as chewing. There are two cusps on maxillary first premolars, and the buccal (closest to the cheek) cusp is sharp enough to resemble the prehensile teeth found in carnivorous animals. There are no deciduous maxillary premolars.

The maxillary second premolar is one of two teeth located in the upper jaw, laterally (away from the midline of the face) from both the maxillary first premolars of the mouth but mesial (toward the midline of the face) from both maxillary first molars. The function of this premolar is similar to that of first molars in regard to grinding being the principal action during mastication, commonly known as chewing. There are two cusps on maxillary second premolars, but both of them are less sharp than those of the maxillary first premolars. There are no deciduous (baby) maxillary premolars.

Research of the study group Baumgartner yielded new insights into temporal lobe epilepsy. By investigating 30 patients of this chronic neurological condition, it was revealed that not only the localisation of the epileptic dipole in the temporal region, but also its orientation in space is important. This led to the classification of two subtypes of patients with medial temporal lobe epilepsy, who have different distribution of the seizures (unilateral or bilateral) and also different prognosis.E. Pataraia, G. Lindinger, L. Deecke, D. Mayer, C. Baumgartner: Combined MEG/EEG analysis of the interictal spike complex in mesial temporal lobe epilepsy.

There is a dark mesial streak on the head and thorax and a dark dot at the base of the forewing and one at the costa, near the apex. The wavy transverse lines of the forewing are very variable in intensity, some specimens being almost unmarked (these are known as form barnsi, although this is sometimes treated as a valid species), others being very heavily marked (form kivui, although this form is sometimes treated as a subspecies). The hindwings are paler, but darker at the tornus. The inner marginal black streak and tornal spots are present but variable.

The lingual height of contour is in the middle third of the tooth (not the middle third of the lingual cusp). When divided into thirds from the buccal height of contour to the lingual height of contour, the buccal cusp is at the contact between the buccal and middle thirds and the central groove is at the contact of the middle and lingual thirds. The two cusp variety generally has a groove pattern shaped like a “U” or “H”. Viewed from the occlusal it is more rounded in general and its lingual cusp is positioned slightly to the mesial, while the occlusal table remains squared.

The stapes was thought to be just a structural support between the palate and the stapedial plate of the braincase. In the Acanthostega, it is likely that due to the otic capsule of the brain case being mesial to the stapedial plate, sound was picked up from the palate or the otic notch to allow for rudimentary hearing. It was able to perceive vibrations by opening its mouth by way of the palate. Other factors that caused aquatic tetrapods to spend more time on land caused the development of terrestrial hearing with the development of a tympanum within an otic notch and developed by convergent evolution at least three times.

The lips are thick, with an uninterrupted fold across the lower jaw, and with both the upper and lower lips in some specimens produced in the mesial line. The maxillary pair of barbels are longer than the rostral, and extending to below the last third of the eye. Fins the dorsal arises opposite the ventral, and is three fourths as high as the body; its last undivided ray is smooth, osseous, strong, and of varying length and thickness. Himalayan, Bengal, and Central Indian specimens generally have the spine strong, and from one half to two thirds the length of the head, it rarely exceeds this extent.

The mandibular second molar is the tooth located distally (away from the midline of the face) from both the mandibular first molars of the mouth but mesial (toward the midline of the face) from both mandibular third molars. This is true only in permanent teeth. The function of this molar is similar to that of all molars in regard to grinding being the principal action during mastication, commonly known as chewing. Though there is more variation between individuals to that of the first mandibular molar, there are usually four cusps on mandibular second molars: two on the buccal (side nearest the cheek) and two palatal (side nearest the palate).

These include the relatively long anteroposterior facial length of the premaxilla, the elongate and strongly anteromedially directed dorsomedial process of the premaxilla, and the sharply defined and elevated margin of the perinarial fossa. There are differences between the two taxa such as differences in the relative thickness of dorsal osteoderms and the absence of a denticulate mesial carina on the first premaxillary tooth in Peirosaurus, but not in Uberabasuchus. However, these characters are considered to be minor and their taxonomic value may be individually variable. As postcranial materials of both Peirosaurus and Uberabasuchus are known but are not yet formally described, they are tentatively considered to be valid taxa.

Favorable eruption position of the second permanent molar may result if the first permanent molar is extracted when the child is at the age of between 8–10 years old. This is when the crown formation of the second permanent molar is complete and the mineralization of the bifurcation is commenced. Extraction of first permanent molars before 8 years old increases the chances of the unerupted second permanent premolar drifting distally. Extraction after the age of 10 years reduces the likelihood of the mesial movement of the second permanent molar in to the first permanent molar space and may result in tilting of the second permanent molar.

The toothcomb is kept clean by the sublingua or "under-tongue", a specialized structure that acts like a toothbrush to remove hair and other debris. The sublingua extends below the tip of the tongue and is tipped with keratinized, serrated points that rake between the front teeth. Slow lorises have relatively large maxillary canine teeth, their inner (mesial) maxillary incisors are larger than the outer (distal) maxillary incisors, and they have a diastema (gap) between the canine and the first premolar. The first mandibular premolar is elongated, and the last molar has three cusps on the crown, the shortest of which is near the back.

Over forty types of epilepsy are recognized and these are divided into two main groups: focal seizures and generalized seizures. Focal seizures account for approximately sixty percent of all adult cases. Temporal lobe epilepsy (TLE) is the single most common form of focal seizure. The International League Against Epilepsy (ILAE) recognizes two main types of temporal lobe epilepsy: mesial temporal lobe epilepsy (MTLE), arising in the hippocampus, the parahippocampal gyrus and the amygdala which are located in the inner (medial) aspect of the temporal lobe and lateral temporal lobe epilepsy (LTLE), the rarer type, arising in the neocortex at the outer (lateral) surface of the temporal lobe.

In human dentistry, the maxillary canine is the tooth located laterally (away from the midline of the face) from both maxillary lateral incisors of the mouth but mesial (toward the midline of the face) from both maxillary first premolars. Both the maxillary and mandibular canines are called the "cornerstone" of the mouth because they are all located three teeth away from the midline, and separate the premolars from the incisors. The location of the canines reflect their dual function as they complement both the premolars and incisors during mastication, commonly known as chewing. Nonetheless, the most common action of the canines is tearing of food.

The pre-antorbital fenestra, a small opening in front of or beneath the antorbital opening, is well developed in taxa like Diplodocus and Tapuiasaurus, is nearly absent, like in Camarasaurus and Euhelopus. There were about 12-13 total teeth in the maxilla of Europasaurus, fewer than in more basal taxa (16 teeth in Jobaria and 14-25 in Atlasaurus), but falling within the range of variation in Brachiosauridae (15 in Brachiosaurus to 10 in Abydosaurus). All of the unworn teeth preserved display up to four small denticles on their mesial edges. A small amount of the posterior tooth crowns are slightly twisted (~15º), but much less than in brachiosaurids (30-45º).

Unlike most of the Ursoidea species, K. beatrix had strong distal cusps on the premolars and a relatively forward-positioned metaconid. In addition, K. beatrix had a more strongly developed sectorial blade in the trigonid, and relatively shorter second molar talonid. These traits indicate a need for pronounced chewing and grinding, and suggest that these enhanced molars and premolars were evolved to more efficiently break down hard plant tissues. The fossil records for these teeth structure suggest that the early development of the distal and mesial cusps on the premolars of K. beatrix may indicate an evolutionary trend towards more complex premolars for the plant-feeding Ursoidea species, and may explain why extant giant pandas have very complex molars.

In the early 1950s, during brain mapping studies with Penfield and Jasper, Feindel discovered the role of the amygdala in patients with temporal lobe seizures, which, with related studies at the MNI, led to the operation of antero-mesial temporal lobe resection often referred to as "the Montreal procedure", an operation adopted worldwide for the surgical cure of many thousands of patients with epilepsy. Feindel was curator of the Wilder Penfield Archive. He was the Chancellor of Acadia University from 1991 to 1996 and then Honorary Governor. In 1998 he was elected Honorary Osler Librarian by the Board of Curators of the Osler Library of the History of Medicine at McGill University.

Australopithecines are generally considered to have had a faster, apelike growth rate than modern humans largely due to dental development trends. Broadly speaking, the emergence of the first permanent molar in early hominins has been variously estimated anywhere from 2.5–4.5 years of age, which all contrast markedly with the modern human average of 5.8 years. The tips of the mesial cusps of the 1st molar (on the side closest to the premolar) of KNM-ER 1820 were at about the same level as the cervix (where the enamel meets the cementum) of its non-permanent 2nd premolar. In baboons, this stage occurs when the 1st molar is about to erupt from the gums.

Treatment priority index (TPI) was created in 1967 by R.M. Grainger in Washington D.C United States. Grainger described the index as “a method of assessing the severity of the most common types of malocclusion, the degree of handicaps or their priority of treatment”. In the index there are eleven weighed and defined measurements which are: upper anterior segment overjet, lower anterior segment overjet, overbite of upper anterior over lower anterior, anterior open bite, congenital absence of incisors, distal molar relation, mesial molar relation, posterior crossbite (buccal), posterior crossbite (lingual), tooth displacement, gross anomalies. It also includes the seven maloclussion syndromes: maxillary expansion syndrome, overbite, retrognathism, open bite, prognathism, maxillary collapse syndrome and congenitally missing incisors.

Interim palatal lift prostheses retentive clasps that engage undercuts formed with composite resin or orthodontic brackets are fashioned from custom bent orthodontic wire that is embedded in the polymethylmethacrylate component of the prosthesis. The orthodontic wire extends from the polymethylmethacrylate to engage the gingival aspect of the composite resin or orthodontic bracket serving to provide the prosthesis’ retentive undercut. If the orthodontic wire clasp terminated at its approximation with the dental abutment undercut it engages as do conventional removable partial denture clasps, the interim palatal lift prosthesis could be difficult to insert and remove. Thus, the orthodontic wire clasps used to retain interim palatal lift prostheses are sometimes extended in a mesial direction up to two mesiodistal tooth diameters.

Oral view of Berryteuthis magister, showing the arrangement of suckers Morphologically, armhook squid are fairly uniform: all species are characterised by the suckers of their arms, which are arranged in four rows (series) rather than the typical count of two. In most species, the arm's two mesial rows of suckers have been modified into hooks and the tentacular clubs --which are covered with many irregular rows of tiny suckers--may possess an enlarged central hook, with or without several smaller hooks. In the magister armhook squid (Berryteuthis magister), only the females possess hooks. Species of the genus Gonatus differ from the rest of the family (and from most squid) by their lack of tentacles as adults.

They may require less radiation and are processed much more quickly than conventional radiographic films, often instantly viewable on a computer. However digital sensors are extremely costly and have historically had poor resolution, though this is much improved in modern sensors. explorer. Radiographic evaluation, (B), however, revealed an extensive region of demineralization within the dentin (arrows) of the mesial half of the tooth. When a bur was used to remove the occlusal enamel overlying the decay, (C), a large hollow was found within the crown and it was discovered that a hole in the side of the tooth large enough to allow the tip of the explorer to pass was contiguous with this hollow.

The mandibular first molar or six-year molar is the tooth located distally (away from the midline of the face) from both the mandibular second premolars of the mouth but mesial (toward the midline of the face) from both mandibular second molars. It is located on the mandibular (lower) arch of the mouth, and generally opposes the maxillary (upper) first molars and the maxillary 2nd premolar in normal class I occlusion. The function of this molar is similar to that of all molars in regard to grinding being the principal action during mastication, commonly known as chewing. There are usually five well-developed cusps on mandibular first molars: two on the buccal (side nearest the cheek), two lingual (side nearest the tongue), and one distal.

The mandibular first molar has five cusps: the mesiobuccal (MB, toward midline and cheek), mesiolingual (ML, toward midline and tongue), distolingual (DL, away from midline and towards tongue), distobuccal (DB, away from midline and toward cheek), and distal (D, away from midline), listed in order of decreasing size. Listed in order of decreasing height they are: ML, DL, DB, MB, and D. An eighth cusp was found in a primary second lower molar in an Argentinean child. Viewed from the top of the tooth (occlusal view), the mandibular first molar is pentagonal (five sided) in shape and tapers toward the lingual, with the sides being the buccal surface, the mesial surface, the lingual surface, distal surface, and the distobuccal surface. The occlusal surface has four grooves.

There have been reports where Non-Asiatic Groups such as Europeans, Sub Saharan Africans, and South Asians, having Shovel Shape Teeth, but that could be the case of having East Asian or Native American Ancestry In some instances, incisors can present a more pronounced version of this called double shovel-shaped. When present, shovel-shaped incisors can indicate correlation among populations and are considered to be one of the non-metrical traits in osteology. Structurally resembling the shovel-shaped incisors, double-shovel-shaped incisors are distinguished by a more pronounced mesial ridge comparing to the distal ridge. Similarly, the grades for both shovel-shaped incisors and the double shovel-shaped incisors in females are significantly greater than that in males.

Orthodontic space closure is a way of using orthodontics in order to close spaces in the mouth where the teeth are missing. The ideal age for definitive orthodontic treatment is early adolescence but it is important to consider the patient’s age, severity of hypodontia, patient expectations and their commitment to treatment. It can be an option for hypodontia management in the case of missing maxillary lateral incisors through the reshaping, and mesial re- positioning of the adjacent canine. This management is indicated in hypodontia cases of Class I molar relationship with severe crowding in the mandibular anterior region where the extraction of lower premolar leads to a predictable outcome, and Class II molar relationship in the absence of crowding and protrusion of the mandibular anterior dentition.

When moving the canine into the space of the lateral incisor, the dimensions of the canine, root position and gingival position differ from a lateral incisor and therefore preparation of the canine is necessary in order for it to mimic the incisor. This may involve: \- Reduction of the incisal tip and addition of composite on the incisal edge to create a straight contour and a rounded disto-incisal corner \- Reduction of the mesial and distal surfaces to reduce the width of the tooth \- Flattening of the labial surface to reduce bulbosity. However, removal of enamel by expose the darker coloured dentine and therefore further restoration may be required. \- Preparation of the palatal surface of the canine to reduce its bulk.

Tribosphenid mammals were originally grouped on the basis of triangular or V-shaped (tribosphenic) molars. Since then, other unrelated mammal groups have been found to have tribosphenic molars, such as the australosphenidans (a group that includes the still extant monotremes), suggesting that as a synapomorphy this is fundamentally useless as it evolved multiple times among mammals. However, a clade between the aforementioned groups, the "true Tribosphenida" or Boreosphenida, is still identifiable, united by characteristics such as the lack of a mesial cingulid and of a triangulated trigonid on the last premolar. They are also united by postcranial features such as the presence of a modern ear (though this too has evolved independently in many other groups, like monotremes), modern shoulder blades, and several features of the hindlimb.

Boreosphenida (from boreas, "northern wind" and sphen, "wedge") were early mammals that originated in the Northern Hemisphere and had tribosphenic molars (three-cusped cheek teeth). In boreosphenidans, the mandibular angle is placed posteriorly and the primitive postdentary trough (hole in the mandible) is absent (in contrast to Kuehneotheriidae, Eupantotheria, and Australosphenida.) They share the tribosphenic molars with the Australosphenida but differ from them by having cingulid cuspules but lacking a continuous mesial cingulid. Boreosphenidans also lack the triangulated trigonid on the last premolar found in Early Cretaceous mammals. They differ from Shuotherium (a monotreme- relative) in having the talonid placed posterior to the trigonid (like in modern tribosphenic mammals) in the lower molars, but upper molars similar to those of Shuotherium.

These coordination signals are sent simultaneously to their effectors. In bimanual tasks (tasks involving two hands), it was found that the functional segments of the two hands are tightly synchronized. One of the postulated theories for this functionality is the existence of a higher, "coordinating schema" that calculates the time it needs to perform each individual task and coordinates it using a feedback mechanism. There are several areas of the brain that are found to contribute to temporal coordination of the limbs needed for bimanual tasks, and these areas include the premotor cortex (PMC), the parietal cortex, the mesial motor cortices, more specifically the supplementary motor area (SMA), the cingulate motor cortex (CMC), the primary motor cortex (M1), and the cerebellum.

The preserved part of the maxilla bears 12 tooth sockets but the original maxillary tooth count might have been much higher. A number of isolated teeth were attributed to Pannoniasaurus that are similar to Halisaurus, being conical and curved posterolingually, bear crowns with fine anastomosing longitudinal striae, and have a strong mesial but weaker labiodistal carina. A single vertebra of Pannoniasaurus (MTM V.2000.21), as well as a variety of fish and crocodile teeth, were collected from the waste dump of the subterranean Ajka coal mine. The Ajka Coal Formation interdigitates with the Csehbánya Formation, the depositional environment of the latter was a floodplain, while the Ajka Coal Formation was formed in the accumulation basin of the same river system.

In this bilateral balanced occlusal scheme, the posterior teeth are set up at different angles in the coronal plane; 5° for the first premolar teeth, 10° for second premolar teeth, and 15° angle for both the first and second molar teeth. In addition, the occlusal surfaces of mandibular posterior teeth are reduced in a buccal lingual dimension with the aim of improving stability of, particularly the lower prosthesis. Regardless which of the above occlusal schemes are adopted, it is difficult to achieve bilateral balanced occlusion in the prosthetic laboratory. Notwithstanding this, this aspiration of bilateral balanced occlusion is easier to achieve if the 'Buccal Upper Lingual Lower (BU-LL) and Mesial Upper -Distal Lower (MU-DL)' rules are adopted for adjusting cusps.

As initially described by Edel, the treatment objective was to increase the zone of keratinized tissue. Others, including Broome and Taggert and Donn also described the use of SECT grafts for increasing the zone of keratinized tissue. Of the various ways of preparing the graft recipient site, Edel described using two vertical incisions, mesial and distal to the teeth at which the zone of keratinized tissue was intended to be widened. At the donor site, Edel described three methods for choosing and preparing the donor site to obtain connective tissue for the SECT graft: # palatal partial thickness flap # palatal full-partial thickness flap # tuberosity partial thickness flap Contrary to the donor site for a free gingival graft, the surgeon is able to achieve primary closure at the donor site for a SECT.

Unlike in GSI/SR/PAL-G074, the dentine on the occlusal surface is not exposed, and the occlusal surface is oval in shape. Furthermore, the V-shaped islet is larger and the lingual furrow is less prominent at the occlusal surface, because it tapers near the tip of the tooth. In the heavily damaged left mf4 GSI/SR/PAL-N071 (height 7.16 mm), only the distal side is well preserved. The infundibulum is exposed internally; it extends 4.01 mm down the crown. The occlusal surface is poorly preserved, but its dimensions are at least 2.14 × 2.42 mm. GSI/SR/PAL-N212, a right mf4, is damaged on the mesial side and has a height of 5.86 mm and an occlusal surface of at least 2.66 x 2.04 mm.

During the resectioning surgery, intraoperative ECoG may also be performed to monitor the epileptic activity of the tissue and ensure that the entire epileptogenic zone is resectioned. Although the use of extraoperative and intraoperative ECoG in resectioning surgery has been an accepted clinical practice for several decades, recent studies have shown that the usefulness of this technique may vary based on the type of epilepsy a patient exhibits. Kuruvilla and Flink reported that while intraoperative ECoG plays a critical role in tailored temporal lobectomies, in multiple subpial transections (MST), and in the removal of malformations of cortical development (MCDs), it has been found impractical in standard resection of medial temporal lobe epilepsy (TLE) with MRI evidence of mesial temporal sclerosis (MTS). A study performed by Wennberg, Quesney, and Rasmussen demonstrated the presurgical significance of ECoG in frontal lobe epilepsy (FLE) cases.

Anterior temporal lobectomy is the complete removal of the anterior portion of the temporal lobe of the brain. It is a treatment option in temporal lobe epilepsy for those in whom anticonvulsant medications do not control epileptic seizures. The techniques for removing temporal lobe tissue vary from resection of large amounts of tissue, including lateral temporal cortex along with medial structures, to more restricted anterior temporal lobectomy (ATL) to more restricted removal of only the medial structures (selective amygdalohippocampectomy, SAH). Nearly all reports of seizure outcome following these procedures indicate that the best outcome group includes patients with MRI evidence of mesial temporal sclerosis (hippocampal atrophy with increased T-2 signal.) The range of seizure-free outcomes for these patients is reported to be between 80 and 90%, which is typically reported as a sub-set of data within a larger surgical series.

In tasks requiring individuals to make predictions when there is some degree of uncertainty about the outcome, there is an increase in activity in area BA8 of the frontomedian cortex as well as a more generalized increase in activity of the mesial prefrontal cortex and the frontoparietal cortex. The prefrontal cortex is generally involved in all reasoning and understanding, so these particular areas may be specifically involved in determining the best course of action when not all relevant information is available. In situations that involve known risk rather than ambiguity, the insular cortex seems to be highly active. For example, when subjects played a 'double or nothing' game in which they could either stop the game and keep accumulated winnings or take a risky option resulting in either a complete loss or doubling of winnings, activation of the right insula increased when individuals took the gamble.

For the latter two, cranial and mandibular elements, besides teeth of deer from Ille Cave were compared with samples of the Calamian hog deer, Philippine brown deer, and Visayan spotted deer, and thus two taxa of deer have been identified from the fossils: Axis and Cervus. Throughout deposits of the Terminal Pleistocene and early Holocene and Terminal Pleistocene at Ille Cave, elements of deer skeletons are regular, gradually becoming less before vanishing in the Terminal Holocene. One 'large' and one 'small' taxon can be easily differentiated by the significant change in size observed in the postcranial elements and dentition. From comparisons of the mesial-distal and labio-lingual measurements of individual fossil teeth and mandibular toothrows with those of surviving deer taxa in the Philippines and other Southeast Asian islands, it appears that the Calamian hog deer is most plausible candidate for the small taxon.

Historically, the VDO has been estimated at 3 mm less than VDR because a person will generally maintain their mandible at an opening of 3 mm when at rest.Bhat, VS; M Gopinathan, M: Reliability of determining vertical dimension of occlusion in complete dentures: A clinical study, JIPS 2006 6:1:38-42 There is another practical rule that applies to many mammals which give us a very practical way to find a suitable VDO. Take the distance between the corner of the eye and the same corner in the lips (in older people the measurement should be done a little more to mesial, closer to the nose, to avoid that downpointing tip )and using a ruler apply it between the center bottom of the nose (that rises from the upper lip) and lower tip of the mandible center. (In completely edentulous, with no teeth, as referred.) Maintaining centric position.
