TRATAMENTO E ANÁLISE HISTOPATOLÓGICA DE ODONTOMA COMPLEXO: RELATO DE CASO

Abstract

Odontoma is a benign calcifying odontogenic tumor of unknown etiology, although local trauma, genetic factors, and chronic inflammation may be related. They are classified into compound and complex types, depending on the morphological, radiographic and histological characteristics. Clinically they hardly show signs or symptoms, and, when present, are related to delayed tooth eruption, cortical bone expansion and tooth displacement. Although radiographic exams are complementary, most cases of odontomas reported in the literature are found on routine radiographs. The diagnostic hypothesis is confirmed by histopathological examination that shows evidence of the presence of enamel, dentin, cementum and pulp tissue arranged in the form of denticles (compound) or a disorganized mass (complex). The treatment consists of surgical excision of the lesion. The aim of this article was to report a clinical case and histopathological analysis of a complex odontoma associated with an unerupted tooth, located on the left side in the posterior region of the maxilla, discovered by routine radiographic examination of a 57-year-old male patient. The treatment was surgical excision of the lesion, removal of the unerupted tooth and histopathological examination, which confirmed the diagnosis of complex odontoma. The case was followed-up clinically and radiographically for one year and showed no recurrence.
