Odontomas are the most common odontogenic benign tumors categorized as hamartomas. Odontoma is primarily made up of enamel and dentin, although it may also contain cementum and pulp tissue in various forms. It is known for having slow-growth and non-aggressive nature. It is made up of either dental tissues categorized as a complex or a compound odontoma based on radiological and histological characteristics. Complex odontomas are less prevalent among them, and they usually show as a tiny, silent radiopaque mass enclosed by a radiolucent border, seen on routine radiographic examinations. To avoid tooth eruption disturbances and additional clinical problems, odontomas should be managed and surgically removed once they have been detected. The present study describe a rare case of giant complex odontoma in the posterior mandible with an unusual dimension in a 16-year-old Iranian female patient referred to the Department of Oral and Maxillofacial, Mashhad Dental School, Mashhad, Iran, in May 2021. The case was effectively treated with surgical curettage and tumor enucleation, emphasizing the significance of early detection to minimize complications. Additionally, the clinical, radiological, and histopathological aspects and probable surgical treatments were discussed.
