摘　　要：牙颈部外吸收是一种起始于根颈部的特殊类型牙根外吸收,由破牙细胞活动引发牙体硬组织破坏。牙颈部外吸收是一个复杂动态的过程,最初仅涉及牙周韧带、牙骨质和牙本质,逐步进展牙髓组织也可能受到影响。由于早期病变往往表现为潜伏性,可能会被忽视,直到晚期出现症状才被发现。本文针对牙颈部外吸收的诊断及生物学机制进行阐述,旨在为牙颈部外吸收的预防及早期治疗提供参考。External cervical resorption is a special type of external root resorption that begins with the cervical of teeth,which is a pathologic phenomenon with a characterization of the hard tissue destruction due to the abnormal activities of odontoclasts.External cervical resorption is a complex and dynamic process that initially involves only periodontal ligaments,cementum,and dentin.In more advanced cases,the resorption lesion can affect the pulp tissue.Early lesions tend to appear latent,therefore they may be overlooked and not detected until symptoms appear at an advanced stage.This paper reviews the diagnosis and biological mechanism of external cervical resorption,and aims to provide a reference for the prevention and early blocking treatment of external cervical resorption.
