Abstract
Introduction: Central Ossifying Fibroma is a rare benign true tumor that requires a combination of clinical, radiographic, and histopathological exams to be diagnosed. This lesion is asymptomatic, but it can grow into large sizes causing facial asymmetry. It may have aggressive behavior and it arises from the periodontal membrane where it contains multipotent cells capable of forming cementum, lamellar bone and fibrous tissue. In the jaws, they often involve the mandible and there may be dental dislocation. The treatment is done by surgical enucleation. Case Detail: The present study reports a clinical case of a Central Ossifying Fibroma of mandible, focusing on its clinical, imaging and histopathological characteristics and treatment, as well as reviewing the literature about the subject. Female patient sought care complaining of the appearance of the lesion after a tooth extraction. The lesion was diagnosed as Central Ossifying Fibroma, the treatment was enucleation surgery and mandibular reconstruction was done with the titanium hollow screw reconstruction plate. The patient had a good prognosis and there was no relapse until the present moment. Discussion: In the radiographic comparison, it is presented, depending on the stage of development, well delimited with well defined limits. In this case, it was found a diffuse border lesion, which is contradictory with the literature.
