Abstract

Odontoma, hamartomas of odontogenic orgin, are composed of all the structures that make up teeth, which may lead to interference with the eruption of its associated tooth. On the basis of gross, radiographic, and microscopic features, two types of odontoma are recognized: compound and complex. The etilogy of odontomas is unknown, although local trauma, infection, and gentic factors have been suggested. Odontomas occur central in bone between the roots of teeth and the mauority are asymptomatic. Although these tumors occur frequently and constitute 22% of all odontogenic tumors, are very rare. Erupted odontoma are defined as tumors that it occurs a calcifed mass may be defected on the ridge. The treatment of chico is the surgical removal of the lesion followed by a biopsy. This report presents a case of 8-year-old girl with the delayed eruption of the mandibular first molar by the calcified mass within the operculum covered the central fossa. And it was diagnosed as erupted complex odontoma by excisional biopsy.
