Tratamento de odontoma complexo e odontectomia parcial intencional em dente associado.

Abstract

An odontoma, considered to be an hamatomatous odontogenic lesion, is divided into compound and complex, according to the tissues degree of diferentiation, and to the resemblance with the normal teeth. The majority of the cases is asymptomatic and found, usually, through routine radiographic exams. The main objective of this study is to report a case of a complex odontoma associated with an impacted third molar. The pacient of the masculine sex, age of 23, and led to the Lauro Wanderley University Hospital, in João Pessoa, Paraíba, to evaluate alteration observed in the radiographic exam. During the Cone Beam Computed Tomography analysis, it was detected a radiopaque mass limited by a thin sclerotic halo, associated to the 48 impacted tooth, which suggests a complex odontoma. The proposed treatment strategy was a surgical enucleation of the lesion and an intentional partial odontognomy in an associated tooth accomplished in hospital environment, under general anesthesia. In the tree month postoperative period the procedure was performed without complications. The surgical planning of maxilomandibular complex pathologies should be based on the behavior of the lesions. The permanence of teeth associated with complex odontoma does not appear to be a risk to treatment; however, clinical studies are needed to confirm this hypothesis.
