Odontoma complejo erupcionado: reporte de un caso

Odontomas consist of enamel, dentin, cementum, and pulp tissue. Histologically, they are classified into 2 groups: compounds and complexes. They are also clinically classified into 3 types: Central odontoma (intraosseous), peripheral odontoma (extraosseous or soft tissue odontoma) and erupted odontoma. Epidemiologically they are reported as the most frequent odontogenic tumor, however, the eruption of this type of lesion is rare, and odontoma occurs only in 1.6% of cases.

Odontomas are usually asymptomatic and commonly are radiographic findings, and in some cases are associated with changes in tooth eruption patterns. A case of a large complex odontoma that erupted into the oral cavity associated with a retained molar is presented and discussed.
