摘要： [摘要] 根管器械分离主要是指根管治疗过程中所使用的器械意外折断于根管内或超出根尖孔,它阻碍了根管治疗的顺利进行，并可能影响根管治疗的效果。本文对1995年以来的相关文献进行回顾，对器械分离发生率研究中存在的问题进行了分析，对发生器械分离后取出、旁路通过和根尖外科手等处理方案进行了详细阐述，并初步总结了预防器械分离的要点。

Abstract: Abstract: Instrument separation mainly refers to the endodontic instruments fractured in root canal or beyond the apex by accident in the process of root canal treatment. Such an error prevents the achievement of efficient cleaning and shaping, which in turn possibly results in the failure of the treatment. The aim of the following review was to analyze the literature assessing the endodontic instrument fracture, focusing on its incidence, prevention and treatment.
Key words: instrument separation, nickel-titanium instruments, root canal preparation
