摘　　要：牙颈部外吸收是牙根吸收的一种特殊类型,其病因和发病机制尚不十分明确。早期无明显临床症状,多是在X线检查时偶然发现,因此常错过最佳治疗时机。牙颈部外吸收的诊断和治疗都有一定的难度,但若不加以处理会导致严重的牙体硬组织的缺失,甚至是牙齿的拔除。国内外关于牙颈部外吸收的报道很少,且以病例报告为主。本文将从致病因素、发病机制、临床表现、影像学表现、组织病理学特征、临床诊断和治疗进行系统性综述,以期为临床医生提供一定的参考。External cervical resorption(ECR) is an uncommon form of root resorption. The etiology and pathogenesis of ECR remains obscure. The resorption is generally found serendipitously by radiological examination. Patients are commonly asymptomatic at the early stage;thus, they often miss the best chance to treat ECR. ECR is difficult to diagnose and treat. However, when left untreated, ECR leads to progressive, irreversible loss of hard dental tissue and even teeth extraction. Reports about ECR worldwide are few, most of which are case reports. This paper will systematically review the predisposing factors, pathogenesis, clinical manifestations, radiological presentation, histopathology, clinical diagnosis and subsequent treatment of ECR to provide a reference for clinicians.
