An asymptomatic radiopacity surrounded by a radiolucent line was observed from a panoramic radiograph of an 11-year-old girl. The lesion was associated with the mesial root of the lower right second primary molar. The radiographic appearance of the lesion suggested a benign cementoblastoma. Histological diagnosis after surgical excision of the tumour and extraction of the tooth confirmed the radiographic diagnosis. Benign cementoblastomas associated with primary teeth are extremely rare lesions. To our knowledge, only eight cases have been reported in the literature.
在一名11岁女孩的全景X光片上观察到一个无症状的不透射线区，其周围有一条射线可透过的线。该病变与右下第二乳磨牙的近中根相关。病变的影像学表现提示为良性成牙骨质细胞瘤。肿瘤手术切除及牙齿拔除后的组织学诊断证实了影像学诊断。与乳牙相关的良性成牙骨质细胞瘤是极其罕见的病变。据我们所知，文献中仅报道了8例。
