ABSTRACT
Osteoma is a benign tumor of bone. Although most commonly occurs in the craniofacial region, the mandible is the rare site of involvement. The mass causes symptoms according to localization and size. Panoramic radiography and computed tomography are the preferred methods used for the diagnosis of osteoma. In this case report, we present a case of mandibular osteoma that despite had reached a very large size, did not produce any signs or symptoms except for the presence of a mass.
