A rare case of benign cementoblastoma involving multiple deciduous and permanent teeth is presented with a review of the literature. A 12-year-old boy was admitted for a swelling in the right maxillary premolar-molar region. A radiologic examination revealed a well-defined, round, radiopaque mass extending from the right maxillary first premolar to the second permanent molar. The tumor was removed with all associated teeth. A histologic examination of the surgical specimen revealed a well-circumscribed tumor composed of cementum-like tissue surrounded by a fibrous capsule. The tumor was attached to the roots of the second deciduous molar, first premolar, and the first and second permanent molars and embedded in the crown and root of the right maxillary second premolar, suggesting that the lesion had arisen from the second deciduous molar. There has been no recurrence of the lesion more than 18 months after the surgical procedure.
本文报告一例罕见的累及多颗乳牙和恒牙的良性成牙骨质细胞瘤病例，并对相关文献进行综述。一名12岁男孩因右上颌前磨牙-磨牙区肿胀入院。影像学检查显示一个边界清晰、圆形的不透光肿物，从右上颌第一前磨牙延伸至第二恒磨牙。肿瘤与所有相关牙齿一并切除。手术标本的组织学检查显示一个边界清楚的肿瘤，由类牙骨质组织构成，周围有纤维包膜。肿瘤附着于第二乳磨牙、第一前磨牙以及第一和第二恒磨牙的牙根，并嵌入右上颌第二前磨牙的冠部和根部，提示病变起源于第二乳磨牙。手术18个月后病变无复发。
