COMPLEX ODONTOMA FUSED TO MANDIBULAR THIRD MOLAR - AN UNUSUAL CASE

Abstract

Odontomas are the most common odontogenic tumours. They are benign, slow growing, nonaggressive, hamartomatous developmental malformations composed of mature tooth substances. Based on the degree of morphodifferentiation or their resemblance to normal teeth, they are divided into compound and complex odontomas. The compound odontoma is composed of multiple, small tooth-like structures. The complex odontoma consists of a conglomerate mass of enamel and dentin, which bears no anatomic resemblance to a tooth. Odontomas are usually asymptomatic and are often discovered during routine radiography. The eruption and infection of odontomas are uncommon. Fusion of odontoma with permanent tooth is also rare. Here we report an unusual case of a complex odontoma fused to the impacted right mandibular third molar.
