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 have been reviewed here. Effective management and appropriate treatment can only be carried out if the true nature and exact location of the ECR lesion are known. This paper reports on the management of a case of external cervical root resorption (ECRR), which involved root canal treatment and removal of the resorbing area of the affected tooth as well as filling the resorbed area with mineral trioxide aggregate (MTA) and resin-modified glass ionomer filling material (RMGIC). The defect was filled with bone graft material and guided tissue regeneration (GTR) membrane. This case highlights the importance of using MTA and successful management of cervical resorption with a stable uneventful clinical recovery.
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；它通常始于牙齿根面的颈部区域。本文回顾了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适当的处理。本文报告了一例外部性颈椎根吸收（ECRR）病例的治疗，该病例包括根管治疗、去除患牙的吸收区域，并用三氧化矿物凝聚体（MTA）和树脂改性玻璃离子充填材料（RMGIC）填充吸收区域。缺损用骨移植材料和引导组织再生（GTR）膜填充。该病例突出了使用MTA的重要性以及颈椎吸收的成功治疗和稳定、顺利的临床恢复。
