The primary goal of endodontic therapy is the reduction or elimination of micro-organisms and their by-products from the root canal system. Although a number of instrumentation and irrigation techniques exist, debris is often left behind in the root canal system, therefore proper canal cleaning, shaping and irrigation is essential to significantly reduce and sometimes eliminate bacteria from canals. However, complete elimination of bacteria is not always achieved in clinical practice due to the anatomical complexities of root canals and consequent limitations of access by instruments and irrigators, the use of antimicrobial medication has been advocated to disinfect the root canal system and because root tissues are closely related to the periodontal apparatus. The aim of this paper is to review current information on the topic of bacterial infection in endodontics with an emphasis on combined mechanical and chemical treatment of root canals. It focuses on available irrigation agents, provides their short overview, mechanism of action and possible unwanted side effects on periodontal tissues (Fig. 2, Ref. 19).
牙髓治疗的主要目标是减少或消除根管系统中的微生物及其副产物。尽管存在多种根管预备和冲洗技术，但根管系统中常常会残留碎屑，因此，适当的根管清理、塑形和冲洗对于显著减少甚至有时消除根管内的细菌至关重要。然而，由于根管解剖结构复杂，器械和冲洗器难以完全到达根管各处，在临床实践中并不总能完全消除细菌，因此有人主张使用抗菌药物对根管系统进行消毒，这是因为牙根组织与牙周组织密切相关。本文旨在综述牙髓病细菌感染这一主题的当前信息，重点关注根管的机械和化学联合治疗。文章聚焦于现有的冲洗剂，简要介绍了它们、作用机制以及对牙周组织可能产生的不良副作用（图2，参考文献19）。
