Adenomatoid odontogenic tumor

The adenomatoid odontogenic tumor is an odontogenic tumor arising from the enamel organ or dental lamina. It is more common in young people and affects females more than males. The most common location is in the anterior maxilla. In 75% of cases, it is associated with an unerupted tooth. 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.Radiographs will exhibit faint flecks of radiopacities surrounded by a radiolucent zone.
