Cisto ósseo traumático associado a odontoma composto: relato de um caso incomum.

Abstract

Traumatic bone cyst (TBC) is a pseudocyst that usually presents asymptomatically and is found frequently in routine exams. Another lesion also present in the jaws is odontoma. The odontoma is divided into two subtypes, the compound and the complex; odontomas are usually discovered as an accidental finding, since they do not present symptomatology. The present article aims to report an unusual case of a TBC associated with a composite odontoma. A 16-year-old male patient attended the Clinic School of Dentistry of the Universidade Federal de Campina Grande (UFCG), Patos-PB campus, referenced by the dentist after identify radiolucent lesion in the anterior region of the mandible on radiographic examination for orthodontic treatment. During the anamnesis, the patient did not report any systemic alteration or underlying disease, but reported trauma in the region affected in childhood. The intra oral clinical examination, was not observed any increase in volume in the region. Palpation was performed in the region, and there was no report of pain. When analyzing panoramic radiography the presence of small calcified structures with radiopacity similar to dental structures was observed, delimited by a radiolucent line, suggestive of compound odontoma. To better location, delimitation, compared with anatomy and surgical planning of the injury, it was requested an cone beam computed tomography (CBCT). Based on the clinical and radiographic findings, we opted for a surgical approach to cystic lesion and enucleation of composite odontoma, under local anesthesia. In the one-year postoperative period, the patient progresses satisfactorily without clinical complaints.
