A 65-year-old Caucasian male was referred to an endodontic specialist practice in a private clinic in December 2019 for the management of an asymptomatic, radiolucent lesion located at the cervical level of the distal root of his right lower first molar, noticed during a routine periapical radiograph. After an accurate evaluation with cone-beam computed tomography (CBCT), the subgingival lesion was diagnosed as a supracrestal external cervical resorption (ECR), with a circumferential spread ⩽90°, confined to dentine without pulp involvement. The lesion was treated with the following sequence: (1) a full flap accessed the ECR, (2) the granulomatous tissue was removed from the root area, (3) the cavity was refreshed and filled with a well-refined and polished resin composite, (4) the flap was sutured at the cemento-enamel junction. A mandibular CBCT scan was performed before treatment, right after treatment, and 3 years postoperatively. Compared to the 3-year posttreatment CBCT scan, the immediate posttreatment one, revealed the absence of bone loss and an unexpected coronal bone remodeling with new bone formation over the treated lesion.
一名65岁的白种男性于2019年12月被转诊至一家私人诊所的牙髓病专科，以处理在常规根尖片检查时发现的位于其右下第一磨牙远中牙根颈部的无症状放射性透射区病变。经锥形束计算机断层扫描（CBCT）精确评估后，龈下病变被诊断为龈上型颈缘外吸收（ECR），圆周扩散≤90°，局限于牙本质且未累及牙髓。该病变按以下步骤进行治疗：（1）通过全层瓣暴露ECR；（2）从牙根区域清除肉芽组织；（3）清理窝洞并充填精心调制和抛光的树脂复合材料；（4）在牙骨质-釉质界处缝合瓣。在治疗前、治疗后即刻以及术后3年进行了下颌CBCT扫描。与术后3年的CBCT扫描相比，治疗后即刻的扫描显示无骨质丧失，且在治疗病变上方出现了意外的冠部骨重塑和新骨形成。
