Adenomatoid odontogenic tumor associated with impacted maxillary premolars: report of 2 cases

Adenomatoid odontogenic tumor (AOT) is a relatively rare, asymptomatic benign tumor of tooth-bearing sites of the jaw that preferentially affects younger females. Radiographically, this lesion typically appears as a well-circumscribed, somewhat teardrop-shaped radiolucency containing an embedded tooth, most often a permanent maxillary canine, with occasional clusters of calcific aggregates and surrounded by a corticated border. Histopathologic findings demonstrate rosettes, duct-like structures, and focal areas of calcification. This article presents 2 cases of AOT associated with impacted maxillary premolars.
