Abstract

Odontoameloblastoma (OA) is an extremely rare mixed odontogenic tumor with both epithelial and mesenchymal components. OA develops from proliferating odontogenic epithelium and mesenchymal tissue. Till date, around 20 cases have fulfilled the histologic criteria of the current World Health Organization (WHO) histologic classification of odontogenic tumors. It affects predominantly young patients with a median age of 20.12 years, and has a predilection for males and occurs in posterior segments of either jaw with slight inclination for mandible. Review of literature shows only three reported cases in the anterior mandible. Here, we report a case of OA in the anterior mandible.

Keywords: Odontoameloblastoma; ameloblasic dentinoma; mixed odontogenic tumor.
