External cervical resorption (ECR) refers to a pathological state in which resorption tissues penetrate into the dentin at the cervical aspect of the root. Despite being latent in its initial phase, ECR could cause severe damage to mineralized dental tissue and even involve the pulp if not given timely diagnosis and treatment. Nevertheless, the etiology of ECR is still poorly understood, which adds to the difficulty in early diagnosis. ECR has received growing attention in recent years due to the increasing number of clinical cases. Several potential predisposing factors have been recognized in cross-sectional studies as well as case reports. In the meantime, studies on histopathology and pathogenesis have shed light on possible mechanisms of ECR. This review aims to summarize the latest findings in the pathogenesis and potential predisposing factors of ECR, so as to provide pragmatic reference for clinical practice.
颈部外吸收（ECR）是指吸收组织侵入牙根颈部牙本质的一种病理状态。尽管ECR在初始阶段具有隐匿性，但如果不及时诊断和治疗，可能会对矿化的牙体组织造成严重损害，甚至累及牙髓。然而，ECR的病因仍知之甚少，这增加了早期诊断的难度。近年来，由于临床病例数量的增加，ECR受到了越来越多的关注。横断面研究和病例报告已经确认了一些潜在的诱发因素。与此同时，关于组织病理学和发病机制的研究也为ECR的可能机制提供了线索。这篇综述旨在总结ECR发病机制和潜在诱发因素的最新研究结果，为临床实践提供实用参考。
