摘要:

牙髓根尖周疾病是一类细菌感染性疾病,疾病晚期细菌常定植于整个根管系统。临床治疗该类疾病的主要方法是根管治疗术,彻底清除根管内感染是该技术的核心,也是取得治疗成功的关键,其中准确的根管工作长度是彻底清除根管内感染的前提和保证。但如何准确地确定根管工作长度,尤其是确定根尖止点的位置一直是牙髓专科医生讨论的热点话题,并常常给许多临床医生造成疑惑。本文就牙齿根尖解剖结构的复杂性、根尖止点确定存在的疑惑以及根管工作长度确定方法作简要介绍。

Abstract:

Pulpitis and periapical periodontitis is a type of bacterial infectious disease, and bacteria frequently plant in the entire root canal system during the terminal stage. Main clinical treatment strategy of the disease requires root canal therapy, a key and core procedure for the successful treatment by thoroughly removing the root canal infection. The premise and guarantee of thoroughly removing root canal infection is by determining the accurate root canal working length. However, methods of accurately determining root canal working length, especially determining the position of apical stop, has been a hot topic among endodontic specialists, frequently causing confusion among many clinicians. This review provides a brief introduction of the complexity of the apical root anatomical structure, the confusion in determining the position of apical stop, and the method to determine the root canal working length.
