The cementoblastoma benign (CB) is a rare odontogenic tumor, slow growth and unlimited. It occurs more frequently in caucasians, between 2nd and 3rd decades of life, with no predilection for gender. More common in the mandible area of molars and premolars, usually involving the first permanent molar. In radiographic image shows a radiopaque mass bounded by thin radiolucent line simulating a hypercementosis. Using histological resembles strongly with osteoid osteoma, osteosarcoma and benign osteoblastoma. The aim of this study was to describe an unusual case of cementoblastoma. IDS, male, melanoderma, 32 years old, came to the Grupo de Apoio Aprendizes do Amor Cristão - GAAAC, Brasília - DF, without pain, with a lesion in the 2nd left molar region, presenting radiographic image suggestive of cementoblastoma. The treatment consisted of complete removal of the lesion accompanied by the extraction of the tooth 37. After two years, there was remission of signs, with no tumor recurrence. This case presents unusual variant as the fact that it involved an individual of black, related to 2nd left mandibular molar - 3%. The rarity of the condition and the discrepancies found between this case and the literature of reinforce even more the importance of any new evidence related to cementoblastoma.
