Extensive Mandibular Ameloblastic Fibro-Odontoma.

Ameloblastic fibro-odontoma (AFO) is a mixed odontogenic tumor that presents epithelial and mesenchymal components. Ameloblastic fibro-odontoma is generally diagnosed between the first and second decades of life and normally shows a slow clinical growth in the posterior portion of the maxilla or mandible, being mostly associated with 1 or more impacted teeth. Radiographic features of AFO show a radiolucent well-defined, uni, or multilocular defect due to containing variable amounts of calcified material. The enucleation of the tumor is the usual conduct and should be followed up for a long period of time. Here, the authors report the case of 17-year-old male patient who presented an extensive AFO on the right posterior side of the mandible. The panoramic radiograph and the tomographic examination revealed a multilocular radiolucent lesion with impacted teeth. Histological examination revealed connective tissue resembling the dental papilla along with epithelial strands or islands, as well as dental hard tissue such enamel and dentin. Enucleation and curettage was performed and led to good outcome. There was no recurrence after an 8-year follow-up, and oral rehabilitation was performed with dental implants.
