Unusual giant complex odontoma: A case report.

Odontomas are benign, non-aggressive, and the most common odontogenic tumor of the jaws. Composed of dental tissues, it can be classified as compound or complex odontomas depending on their radiological and histological features. Among them, complex odontomas are less common and usually is presented as a small and asymptomatic radiopaque mass surrounded by a radiolucent halo, found on routine radiographic examination. Although benign tumors, odontomas can reach large sizes leading to facial asymmetry and decreasing bone strength, which predisposes fractures and infection. Our aim was to present a case report of an unusual giant mandibular odontoma on the left mandibular angle and ramus successfully treated by surgical excision and highlight the importance of the earlier diagnostic to minimize damages.
