摘　　要：牙髓病和根尖周病的常见类型均由细菌感染所致,因此牙髓治疗的核心是感染控制,首选方法是根管治疗术。由于根管内感染的复杂性、根管解剖系统的多样性和现有技术的局限性等多种因素,感染控制成为根管治疗过程中的难点问题,而机械化学预备是感染控制的关键步骤。文章就根管内感染控制的难点及策略做一介绍。The most common types of pulpitis and apical periodontitis are caused by microbial infection,thus the core of endodontic treatment is infection control and the preferred method is root canal therapy.The infection variety,anatomic complexity of root canal and limitation of current technology make it difficult to control infection,and mechanochemical preparation is a critical procedure of root canal therapy.In this article,the difficulties and strategies of control for root canal infection were introduced.
