The adenomatoid odontogenic tumor is an odontogenic tumor[1] arising from the enamel organ or dental lamina.
Epidemiology
It is fairly uncommon, but It is seen more in young people. Two thirds of the cases are found in females.[2]
Presentation and diagnosis
Two thirds of cases are located in the anterior maxilla, and one third are present in the anterior mandible.[3]
Two thirds of the cases are associated with an impacted tooth (usually being the canine).
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.
It is sometimes misdiagnosed as a cyst.[4]
Treatment
Treatment can involve enucleation.[5]
