摘要
根管再治疗是指在初次根管治疗失败后患牙仍旧持续或再次出现感染症状时,需去除原充填物重新进行的根管预备、消毒和充填。根管内残留物是指根管再治疗过程中彻底清理根管后根管内残余的牙胶、碎屑和玷污层,去除原充填物已成为根管再治疗成功的关键。随着各种现代化再治疗器械的问世,根管再治疗中根管内残留物量的评价已经成为衡量它们对根管系统清理能力的指标之一。本文就根管内残留物量的评价方法作一综述。
The re-treatment of failed endodontic treatment includes complete removal of the root filling materials,shaping root canals,disinfection with medicaments and ultimately filling.The remnants within the root canal includes gutta-percha,debris and smear layer after thoroughly root canal preparation.Removing the old filling material is critical for success.The amount of the remnants indicate the ability of the re-treatment equipment.This review was to summarize the methods to evaluate the remnants.
