Ameloblastic fibro-odontoma with a congenitally missing mandibular second molar : a rare case report

Abstract

Ameloblastic fibro-odontoma (AFO) is a rare benign mixed odontogenic tumor predominantly occurring in children. This tumor is often asymptomatic and associated with disturbances in tooth eruption. We present the case of a 7-year-old boy who exhibited delayed eruption of his left mandibular first molar, attributable to AFO with a congenitally missing mandibular second molar. Radiographs revealed a well-defined, ovoid, radiolucent lesion containing sparse calcified materials in the left posterior mandible. To the best of our knowledge, few reports have documented AFO in conjunction with the congenital absence of a permanent tooth. This case is discussed along with a review of relevant literature.
