External cervical resorption (ECR) is the loss of dental hard tissue as a result of odontoclastic action. It is a dynamic process that involves periodontal, dental and in later stages pulpal tissues. Over the last two decades, ECR has attracted increased interest; this is in part due to novel micro-CT and histopathological techniques for its assessment and also improved radiographic detection using CBCT. This literature review will cover the aetiology, potential predisposing factors, histopathology and diagnosis of ECR. Part 2 will cover the management of ECR.
外部性颈吸收（ECR）是由于破牙骨质细胞作用导致的牙体硬组织丧失。它是一个涉及牙周、牙和后期牙髓组织的动态过程。在过去的二十年中，ECR 引起了更多的关注；这部分是由于其评估的新型微 CT 和组织病理学技术，以及使用 CBCT 提高了放射性检测。本文综述将涵盖 ECR 的病因、潜在的诱发因素、组织病理学和诊断。第 2 部分将涵盖 ECR 的治疗。
