External cervical resorption (ECR) is the loss of dental hard tissue as a result of odontoclastic action; it usually begins on the cervical region of the root surface of the teeth. The etiology, predisposing factors, diagnosis, and management of ECR are reviewed. Effective management and appropriate treatment can only be carried out if the true nature and exact location of the ECR lesion are known. The role of cone beam computed tomography as a diagnostic adjunct for the management of ECR is also reviewed.
外部性颈椎吸收（ECR）是由于破牙细胞作用导致牙体硬组织丧失；它通常始于牙齿牙根表面的颈部区域。本文综述了ECR的病因、诱发因素、诊断和治疗。只有了解ECR病变的真实性质和确切位置，才能进行有效的治疗和恰当的处理。本文还综述了锥形束计算机断层扫描作为ECR治疗诊断辅助手段的作用。
