Overview
The adenomatoid odontogenic tumor is an odontogenic tumor arising from the enamel organ or dental lamina. The most common location is in the anterior maxilla. In 75% of cases, it is associated with an unerupted tooth.
Differential Diagnosis
It should be differentially diagnosed from a dentigerous cyst and the main differnce is that the radiolucency in case of AOT extends apically beyond the cementoenamel junction. Radiographs will exhibit faint flecks of radiopacities surrounded by a radiolucent zone.
Epidemiology and Demographics
It is more common in young people and affects females more than males.
Diagnosis
On radiographs, the adenomatoid odontogenic tumor presents as a radiolucency (dark area) around an unerupted tooth extending past the cementoenamel junction.
