Complex and compound odontomas: Analysis of 69 cases and a rare case of erupted compound odontoma

The purpose of this study was to analyze clinic and radiologic features of the 69 odontoma cases and present a rare case of erupted compound odontoma in the oral cavity.

The 69 cases were analyzed with regard to the following parameters: age, gender, location, associated unerupted teeth, missing teeth, radiological and histopathological features and treatment protocols.

Of the 69 cases, 49 were compound odontoma and 20 were complex odontoma. There was a female predilection for both compound and complex odontomas. Compound odontoma occurred more often in the anterior region of the jaws; complex lesions occurred more often at the posterior mandible. The most common clinical manifestations were the retention of permanent teeth.

Compound odontomas rarely erupt into the mouth. The presented case is the 13 th case of erupted compound odontoma reported in the literature. The treatment of choice is surgical removal of the odontoma. In the case of odontomas associated to impacted teeth, the teeth should be preserved in wait of spontaneous eruption, or alternatively fenestration followed by orthodontic traction is indicated. Regular follow-up period is crucial to evaluate the prognosis of these teeth.
