ABSTRACT

Cementoblastoma is a rare benign odontogenic neoplasm. Its cause is unknown. It represents less 6 % of all odontogenic tumors. The aim of our work is to present a rare case of maxillary cementoblastoma involving an included central incisor. A 32-year old man consulted for a left maxillary swelling to projection under nostril. A panoramic radiographic examination revealed an included tooth 21 with a radiopaque lesion around its root. The computed tomography revealed the included tooth 21 with a process around its root. This process is well-defined, high-dense and is surrounded by a radiolucent halo. The treatment should consist of complete removal of the lesion with the tooth 21. Histological examination concluded to the diagnosis of a cementoblastoma. The cementoblastoma occurs most frequently in young persons and predominantly among men. The mandibular premolar and molar are the more frequently reached. The maxillary localization remains rare. This tumor occurs around the roots of the posterior and lower teeth. Radiographically, the lesion is well-defined and attached to the root of the tooth, radiopaque dense and surrounded by a radiolucent halo. The cementoblastoma evolves slowly and has the tendency to blow the cortical. The prognosis is good.
