On radiographs, the adenomatoid odontogenic tumor presents as a radiolucency (dark area) around an unerupted tooth extending past the cementoenamel junction. It should be differentially diagnosed from a dentigerous cyst and the main difference is that the radiolucency in case of AOT extends apically beyond the cementoenamel junction.
Periapical is defined as "the tissues surrounding the apex of the root of a tooth" and a cyst is "a pathological cavity lined by epithelium, having fluid or gaseous content that is not created by the accumulation of pus."
Periapical granuloma, [1] also sometimes referred to as a radicular granuloma or apical granuloma, is an inflammation at the tip of a dead (nonvital) tooth. It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth.
Dental panoramic radiograph showing Stafne defect in the right mandible, below the inferior alveolar nerve canal (arrowed, appears on lower left of image). This x-ray was taken for an unrelated assessment of wisdom teeth, and the Stafne defect was a chance finding. Axial computed tomograph of the same person.
The diagnosis of pulp necrosis can be based on the following observations: negative vitality, a periapical radiolucency, a grey tooth discoloration and even peri-apical lesions. [17] This altered translucency in the tooth is due to disruption and cutting off of the apical neurovascular blood supply.
The radiographic examination showed unilocular, well-circumscribed, round radiolucency in the front, right maxilla extending above the canine to the central incisor (front tooth). [10] Based on clinical and radiographic findings, the diagnosis was considered to be a calcifying odontogenic cyst or calcifying odontogenic tumor.
A couple in Australia have been accused of faking their young son's cancer diagnosis "It will be alleged that the accused shaved their 6-year-old child’s head, eyebrows, placed him in a ...
Radiolucency or hypodensity indicates greater passage (greater transradiancy) to X-ray photons [1] and is the analogue of transparency and translucency with visible light. Materials that inhibit the passage of electromagnetic radiation are called radiodense or radiopaque , while those that allow radiation to pass more freely are referred to as ...
