Cementoblastomas are rare benign odontogenic tumors. Diagnosis of these lesions must be made by an association of clinical, radiographic, and histopathological findings. Cementoblastomas rarely occur in both primary and permanent dentitions. We describe the sixth case of cementoblastoma in the literature with the involvement of both deciduous and permanent teeth. The aim of this case report is to present the clinicoradiopathologic features of a cementoblastoma in a 4.5-year-old boy with an unusual recurrence. The first clinical and radiographic features appeared on the deciduous mandibular second molar. The second lesion occurred 1 year after treatment at 5.5 years old, involving the permanent mandibular first molar, and a subsequent lesion was seen at age 8 years in the edentulous region of the extracted mandibular first molar. After the last surgery, there was no recurrence of the lesion at 6 months' follow-up. Follow-ups of patients with cementoblastomas are highly recommended for an early detection of recurrences.
成牙骨质细胞瘤是一种罕见的良性牙源性肿瘤。这些病变的诊断必须结合临床、影像学和组织病理学检查结果。成牙骨质细胞瘤很少同时发生于乳牙列和恒牙列。我们报道了文献中第六例累及乳牙和恒牙的成牙骨质细胞瘤病例。本病例报告的目的是呈现一名4.5岁男孩发生的具有不寻常复发情况的成牙骨质细胞瘤的临床、影像学和病理特征。最初的临床和影像学表现出现在下颌乳牙第二磨牙。第二次病变发生在5.5岁治疗后1年，累及下颌恒牙第一磨牙，随后在8岁时，在拔除的下颌第一磨牙的缺牙区发现了病变。最后一次手术后，6个月的随访中病变未复发。强烈建议对成牙骨质细胞瘤患者进行随访，以便早期发现复发情况。
