Benign cementoblastoma: case report and review of the literature.

Benign cementoblastoma (BC) is a relatively rare odontogenic neoplasm characterized by the formation of a mass of cementum-like tissue connected to the root of a tooth. Clinically, BC has a slow and constant growth pattern, frequently accompanied by pain, and it promotes volume expansion on both the vestibular and lingual surfaces. Radiographically, it appears attached to the apical or lateral portion of the root of a tooth root as a densely radiopaque, well-circumscribed mass surrounded by a thick and uniform radiolucent halo. Treatment usually consists of surgical tooth extraction along with the attached calcified mass or endodontic treatment of the associated tooth, enucleation of the tumor and osseous curettage. In this article, the clinical, radiographic and histopathological features of one case of BC are presented and the variations of the cases cited in the literature are discussed.
