摘　　要：牙髓病和根尖周病主要由细菌感染所致,治疗的核心是感染控制。由于尚无研究表明根管内感染源可被彻底清除,因此根管预备的目标在于尽可能地去除感染源。感染控制的难点主要包括根管解剖系统的复杂性和根管内微生物种类及毒力的复杂性两方面。机械预备的物理切削作用有助于更好地清除根管系统内的感染牙髓组织、感染牙本质及细菌生物膜,同时根管预备的最终形态很大程度上影响冲洗、封药及充填的质量。文章旨在对根管内感染控制的难点、机械预备清理成形及其与冲洗、封药、充填的关系做一介绍,以便更好地控制根管感染,促进组织愈合,提高治疗成功率。Endodontic and periapical diseases are caused primarily by bacterial infection,and the core of treatment is infection control.Since no study has shown that the source of infection in the root canal can be completely removed,the goal of root canal preparation is to remove as much of the source of infection as possible.The difficulties in infection control include the complexity of the anatomical system of the root canal and the complexity of the microbial species and virulence of the root canal.The physical cutting action of mechanical preparation helps to better remove infected pulp tissue,infected dentin,and bacterial biofilm from the root canal system,and the final shape of the root canal preparation greatly affects the quality of the irrigation,sealing and obturation.The aim of this article is to introduce the difficulties in infection control,the cleaning and shaping of mechanical preparation and its relationship with irrigation,sealing,and obturation,in order to better control root canal infection,promote tissue healing,and improve the success rate of treatment.
