SUMMARY: The clinical, radiographic and histological fea- tures of a mandibular ameloblastic fibro-odontoma (AFO) are presented, and its classification and manage- ment are discussed.
The tumor was an incidental finding in a 12 year-old girl. It manifested as a well-circumscribed radiolucency with radiopaque areas in the ramus and the body of the mandible, surrounding the crown of the impacted second molar and causing jaw perforations. Following enucleation through an intraoral access and extraction of the second permanent molar, complete restoration of the jaw bone was seen in the one year follow-up examination. The microscopic features were consistent with an AFO.
As the neoplastic or hamartomatous nature of AFO and its relation to other mixed odontogenic tumors has not been proved, reports of additional well-documented cases, more comparative studies among AF, AFD, AFO and odontomas, as well as studies of their molecular fea- tures, are needed.
