Cementoblastoma is a benign odontogenic mesenchymal tumor characterized by cementum production. Cementoblastoma is considered a relatively rare neoplasm with a predilection to the posterior region of the mandible. The main clinical differential diagnoses include hypercementosis, cemento-osseous dysplasia, condensing osteitis, idiopathic osteosclerosis, osteoblastoma, odontoma, and osteosarcoma. Imaging findings may be pathognomonic when demonstrative. Although rather identical histologically, cementoblastoma exhibits unequivocal fusion to the root of the tooth, which distinguishes it from osteoblastoma. We present a case of a 30-year-old man with cementoblastoma arising in an unusual location: the root of the second right premolar of the maxilla.
成牙骨质细胞瘤是一种以牙骨质形成为特征的良性牙源性间充质肿瘤。成牙骨质细胞瘤被认为是一种相对罕见的肿瘤，好发于下颌骨后部区域。主要的临床鉴别诊断包括牙骨质增生、骨化性纤维瘤、致密性骨炎、特发性骨硬化、成骨细胞瘤、牙瘤和骨肉瘤。影像学表现若具有特征性，则可能具有诊断意义。尽管成牙骨质细胞瘤在组织学上与其他病变颇为相似，但其与牙根有明确的融合，这使其与成骨细胞瘤相区别。我们报告一例30岁男性患者，其成牙骨质细胞瘤发生于一个不寻常的部位：上颌右侧第二前磨牙牙根。
