Abstract

Adenomatoid odontogenic tumor(AOT) is an infrequent odontogenic tumor which arise in the jaw. It was considered as a variant of ameloblastoma. The adenomatoid odontogenic tumor is clearly benign and, in contrast to the ameloblastoma, present a very low recurrence. It most often appears in the canine region of the maxilla. The adenomatoid odontogenic tumor is frequently asymptomatic, however it may cause painless swelling. The radiological findings of adenomatoid odontogenic tumor frequently share characteristics of dentigerous cyst and unicystic ameloblastoma. Conservative surgical enucleation and curettage are the treatment of choice. In this case a 10-year-old child was presented with mandibular right lateral incisor in unerupted. Radiographically, the tooth was impacted and a radiolucency was seen in the area. The lesion was enuclated without extraction of the tooth. Bracket was attached on the tooth for orthodontic extrusion installed. Histopathologically adenomatoid odontogenic tumor was revealed.
