Hagfish have a unique dental plate inside of their mouths with a row of posterior and anterior keratinous grasping teeth on each side. This dental plate folds bilaterally helping with the grasping motion hagfish use to eat their prey. The dental plate protrudes out and folds onto the flesh of the prey and then retracts back into the hagfish's mouth. It may also use its slime to suffocate its prey though this is mostly used as a defense against predators.

Adult females are mottled brown and their eyes bulge out slightly. Its jaws consist of pebble-like teeth fused into a beak for eating seaweed, but in juveniles the teeth are not yet fully fused and are visible on the outside of the dental plate.

Two local areas that had such water were Hartlepool and Grimsby. All the victim's upper teeth, and all but six of her lower teeth, were missing and an upper dental plate had been fitted. The woman had heavy staining on her remaining teeth which indicated that she smoked and drank heavily and generally, did not look after herself.

Before introduction of the laryngoscope, dental plate should be put in place. After tracheotomy, with a laser-safe endotracheal tube the patient is intubated with an ample exposition of the glottis. A small laser-protected endotracheal tube is placed in case there is no pre-existing tracheotomy.Eckel HE, Perretti G, Remacle M, Werner J. Endoscopic Approach.

She had black/dark brown hair styled in a ponytail and brown eyes. She had a partial upper dental plate with six teeth. She was found wearing a pair of blue/green shorts, a pink blouse with white lace and a pair of blue bedroom slippers with a blue and green floral pattern. Her body was exhumed in 2016 for additional testing.

McMillian, a prisoner had been beaten, garnering a cracked lip, broken dental plate, loosened teeth, cuts, and bruises. Although these were not "serious injuries", the court believed, it held that "the use of excessive physical force against a prisoner may constitute cruel and unusual punishment even though the inmate does not suffer serious injury."Hudson v. McMillian, 503 U.S. 1 (1992).

The lingual apparatus of hagfish is composed of a cartilage base bearing two teeth-covered plates (dental plate) articulated with a series of large cartilage shafts. The nasal capsule is considerably expanded in hagfish, comprising a fibrous sheath lined with cartilage rings. In contrast to lampreys, the braincase is noncartilaginous. The role of the branchial arches is highly speculative, as hagfish embryos undergo a caudal shift of the posterior pharyngeal pouches; thus, the branchial arches do not support gills.

The golden pufferfish uses its beak-like dental plate to feed on the tips of branching corals at an estimated pace of of calcium carbonate per of live coral per day. Despite the large amount of coral consumed, studies suggest that the golden pufferfish has little influence on coral abundance in the region. Parrotfish are a family of fish that contain several corallivorous species. Reef-dwelling parrotfish have teeth on their lower and upper jaw that have evolved into an edge for cutting.

He had medium length brown hair as well as a beard. Two stainless steel surgical rods had been implanted in the man's lower back around the 1960s. He was found wearing Hanes boxers, blue 'Rustler' brand jeans, a black belt, a 'Carriage Street' brand beige shirt, and a Rolex watch. He was also found with various effects, such as two 'Cross' brand pens, a yellow metal necklace with an eagle pendant, a yellow metal ring with a clear stone, a Torx wrench and a dental plate.

Chimeras (Holocephali) have pavement teeth that are flat, hexagonal in shape and interconnect to form an even dental plate. There is the presence of calcified strengthened cartilaginous jaws, calcified struts within the jaws and a lever ‘nutcracker’ system that amplifies the force of the jaw adductor muscles. The fusion of the palatoquadrate and mandibular symphysis, a restricted gape and asynchronous activation of the jaw adductors are key elements in the ‘nutcracker’ model of jaw-crushing ability. Chimeras use their pavement teeth for grinding molluscs, gastropods and crabs.

Hagfish musculature differs from jawed vertebrates in that they do not have a horizontal septum nor vertical septum, junctions of connective tissue that separate the hypaxial musculature and epaxial musculature. They do, however, have true myomeres and myosepta like all vertebrates. The mechanics of their craniofacial muscles in feeding have been investigated, revealing advantages and disadvantages of the dental plate. In particular, hagfish muscles have increased force and gape size compared to similar-sized jawed vertebrates, but lack the speed amplification, suggesting that jaws are faster acting.

Justice Sandra Day O'Connor delivered the opinion of the Court, joined by Chief Justice Rehnquist and Justices White, Kennedy, and Souter. Justices Blackmun and Stevens separately concurred in the judgment. In the case, petitioner Hudson, a Louisiana prison inmate, testified that he suffered minor bruises, facial swelling, loosened teeth, and a cracked dental plate as a result from a beating by respondent prison guards, McMillian and Woods, while he was handcuffed and shackled following an argument with McMillian, and that respondent Mezo, a supervisor on duty, allegedly watched the beating and told the officers "not to have too much fun." Hudson's injuries were "minor" and required no medical attention.

The body of a thirty- to fifty-year-old man was found on November 3, 1995 (although he likely died in 1994) in Somerset County, Pennsylvania, close to the border of Maryland. He had been shot twice in the head, likely around a year before the remains were found. He had possibly been fairly well-to-do, as the body was dressed in a pair of "Genuine Country Road" brand pants that cost around $200 when new, and he had an expensive partial dental plate replacing missing teeth. He was approximately 5 feet 6 to 5 feet 10 inches in height and weighed between 150 and 170 pounds.

To manufacture the product, Hyatt formed the Albany Billiard Ball Company, in Albany, New York's South End in 1868, with assistance from Peter Kinnear and other investors. Hyatt received a patent on nitrocellulose innovation on April 6, 1869. The company initially operated out a machine shop owned by Kinnear, who ultimately became the majority owner and steered the company to market and financial success. In 1870, John and his brother Isaiah patented a process of making a "horn-like material" with the inclusion of nitrocellulose and camphor,US patent #105,338 issued July 12, 1870 and founded a second business, Albany Dental Plate Co. (later the Celluloid Manufacturing Co.), to manufacture more than sporting goods.

Pierce had a reputation for being bad-tempered, or at least extremely stern, but his relationship with Karloff was a good one. They both cooperated on the design of the now iconic make-up, with Karloff removing a dental plate to create an indentation on one side of the Monster's face. He also endured four hours of make-up under Pierce's hand each day, during which time his head was built up with cotton, collodion and gum, and green greasepaint (designed to look pale on black-and-white film) was applied to his face and hands. The finished product was universally acclaimed, and has since become the commonly accepted visual representation of Mary Shelley's creation.

Alexander Parkes had used camphor among his Parkesine solvents, and another Englishman who had worked with Parkes, Daniel Spill, listed camphor as an ingredient in his own variant of nitrocellulose polymer, Xylonite, but it was the Hyatt brothers who recognized the value of camphor's use as a plasticizer for nitrocellulose. Isaiah Hyatt dubbed their material, using this method, Celluloid in 1872. It was put to use by the Albany Billiard Ball Company and its sister company, Albany Dental Plate Co. (later the Celluloid Manufacturing Co.) The name "celluloid" has long since become a genericized trademark. Albany's celluloid-based composite material pool balls dominated the US market until the 1960s, when the increased availability of cheap, imported balls almost ruined the company.

The New Zealand hagfish has a skull but no jaw or true vertebral column, it instead has a skeleton made up of cartilage.(Encyclopedia of Britannica, 2011) The rounded mouth of the hagfish is surrounded by 6 barbels, above that is their singular nasal passage and just inside the mouth is a dental plate with a row of posterior and anterior keratinous grasping teeth on each side. It has seven pairs of gill pouches and forming a line down both the lower sides of its body are pores which often many of them are ringed with a white colour and are used for secreting a snot-like slime which expands out once it has contact with the sea water.(Bray, n.

Aided by his brother Isaiah, Hyatt experimented with Parkesine, a hardened form of nitrocellulose. Parkesine had been invented by the Englishman Alexander Parkes in 1862, and is considered the first true plastic, although it was not a success as a commercial or industrial product. Liquid nitrocellulose, or collodion, had been used as early as 1851 by another English inventor, Frederick Scott Archer, in photographic applications; it had also been used extensively as a quick-drying film to protect the fingertips of printers. Hyatt's eventual result was a commercially viable way of producing solid, stable nitrocellulose, which he patented in the United States in 1869 as "Celluloid" (US patent 50359; now a genericized trademark). In 1870 Hyatt formed the Albany Dental Plate Company to produce, among other things, billiard balls, false teeth, and piano keys, Hyatt’s Celluloid Manufacturing Company was established in Albany, New York in 1872 and moved to Newark, New Jersey in 1873.
