Adenomatoid odontogenic tumor.

The adenomatoid odontogenic tumor (AOT) is usually an asymptomatic slow growth lesion. When grown, one can palpate a hard and large lesion. It is common for the tumor to cause shifting of neighboring teeth because tumor expansion is more common than teeth root resorption. Radiographically, there is a unilocular mass involving an unerupted tooth, sometimes opaque in the center and sclerotic in the periphery. Considering it to be an encapsulated tumor, treatment of choice is enucleation. This paper describes three cases of these tumors and their symptoms, their radiographic characteristics and anatomic findings.
