The affected sinus is partially opacified on radiograph. Air-fluid level in maxillary sinus may sometimes be seen due to presence of blood. Lucency in orbits (on a radiograph) usually indicate orbital emphysema.

Ameloblastoma is tentatively diagnosed through radiographic examination and must be confirmed by histological examination through biopsy. Radiographically, the tumour area appears as a rounded and well-defined lucency in the bone with varying size and features. Numerous cyst-like radiolucent areas can be seen in larger tumours (multi-locular) giving a characteristic "soap bubble" appearance. A single radiolucent area can be seen in smaller tumours (unilocular).

The cupola sign is seen on a supine chest or abdominal radiograph in the presence of pneumoperitoneum. It refers to dependent air that rises within the abdominal cavity of the supine patient to accumulate underneath the central tendon of the diaphragm in the midline. It is seen as lucency overlying the lower thoracic vertebral bodies. The superior border is well defined, but the inferior margin is not.

CT scan showing an osteoid osteoma of the fibula with a clearly visible nidus Radiographs in osteoid osteoma typically show a round lucency, containing a dense sclerotic central nidus (the characteristic lesion in this kind of tumor) surrounded by sclerotic bone. The nidus is seldom larger than 1.5 cm. The lesion can in most cases be detected on CT scan, bone scans and angiograms. Plain radiographs are not always diagnostic.

An implant is tested between 8 and 24 weeks to determine if it is integrated. There is significant variation in the criteria used to determine implant success, the most commonly cited criteria at the implant level are the absence of pain, mobility, infection, gingival bleeding, radiographic lucency or peri-implant bone loss greater than 1.5 mm. Dental implant success is related to operator skill, quality and quantity of the bone available at the site, and the patient's oral hygiene, but the most important factor is primary implant stability. While there is significant variation in the rate that implants fail to integrate (due to individual risk factors), the approximate values are 1 to 6 percent Integration failure is rare, particularly if a dentist's or oral surgeon's instructions are followed closely by the patient.

With regard to gender, women tend to report higher psychological disability after endodontic therapy, and a higher rate of physical disability after tooth implantation, while men do not show a statistically significant difference in response. Mastication is significantly stronger in endodontically treated teeth as compared to implants. Initial success rates after single tooth implants and endodontic microsurgery are similar the first 2 to 4 years following surgery, though after this the success rate of endodontic microsurgery is decreased as compared to implantation. To an extent, the criteria for success due to the inherent differences in the procedure have historically limited comparisons, with success of endodontic therapy defined as the absence of periapical lucency on radiographs, or the absence of visible cavity at the root of the tooth on imaging.

In compound implants (two stage implants), between the actual implant and the superstructure (abutment) are gaps and cavities into which bacteria can penetrate from the oral cavity. Later these bacteria will return into the adjacent tissue and can cause periimplantitis. Criteria for the success of the implant supported dental prosthetic varies from study to study, but can be broadly classified into failures due to the implant, soft tissues or prosthetic components or a lack of satisfaction on the part of the patient. The most commonly cited criteria for success are function of at least five years in the absence of pain, mobility, radiographic lucency and peri-implant bone loss of greater than 1.5 mm on the implant, the lack of suppuration or bleeding in the soft tissues and occurrence of technical complications/prosthetic maintenance, adequate function, and esthetics in the prosthetic.
