M9300/0 |
The adenomatoid odontogenic tumor is an odontogenic tumor[1] arising from the enamel organ or dental lamina.
Epidemiology
It is more common in young people and affects females more than males.[2]
Presentation and diagnosis
The most common location is in the anterior maxilla.[3]
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.
It is sometimes misdiagnosed as a cyst.[4]
Treatment
Treatment can involve enucleation.[5]
