Abstract

OBJECTIVE:

Odontoma is a comparatively common odontogenic tumor, and it may lead to interference with the eruption of its associated tooth. Odontomas are mostly associated with permanent teeth, and they are rarely associated with deciduous teeth. The purpose of this report is to analyze 107 odontomas and to present a case of complex odontoma associated with a lower deciduous second molar.

SUBJECT AND METHODS:

The 106 cases were analyzed with regard to the following parameters: age, gender, location, erupted teeth, congenital missing teeth, radiological features, histopathological features and prognosis.

RESULTS:

Of the 106 cases, 41 were complex odontoma, 62 were compound odontoma, and three were immature odontoma. Compound odontoma had a predilection for the anterior. Complex odontoma occurred more often at the mandible.

CONCLUSION:

Odontoma located above the tooth crown of lower deciduous molar did not behave clinically different from that associated with permanent tooth. An odontoma could be related with a supernumerary tooth or a missing tooth. If odontomas, which interfered with tooth eruption, were extirpated early, the impacted teeth would probably erupt normally and be normal in shape.
