Relevance of Cone-beam computed tomography on diagnosis and surgical planning of the cementoblastoma

Abstract

The cementoblastoma is a rare odontogenic tumor occurring in the mandibular molar and premolar of the patients in the second and third decades of life. Despite its typical benign behavior, this tumor may promote local destruction by perforating the cortical bone and displacing the mandibular canal. This case report shows a 31-year-old man with an aggressive cementoblastoma attached to the apex of the mandibular first molar. Cone-beam computed tomography revealed a hyperdense mass connected to the root of mandibular molar surrounded by a hypodense area. Multiplanar reconstructions showed rupture of buccal bone plate and tumor invasion of the mandibular canal roof. The surgical planning included enucleation of tumor with the first and second molars extractions and the diagnosis of cementoblastoma was confirmed by histopathology. This case report emphasizes the contribution of cone-beam computed tomography on diagnosis and appropriate surgical planning of the cementoblastoma. Key words: Cone-Beam computed tomography, odontogenic tumors, diagnosis.

Evaluation, Treatment, Complication and Prognosis of Ameloblastoma

“…Radiographic techniques such as radiographs and cone beam computed tomography (CBCT) play a role in visualizing the extent and characteristics of the tumor aiding in precise treatment planning. To confirm the presence of ameloblastoma and identify its subtype a definitive diagnosis relies on histopathological examination of a biopsy specimen (21,22). The three main types of ameloblastoma which're unicystic and rare variants, have distinct clinical behaviors that greatly impact the treatment approach.…”
