摘要
根管预备是根管治疗术中的重要环节,也是保证疗效的关键步骤。根管预备包括根管清理和根管成形,为严密的根管充填创造良好的条件。由于根管系统的复杂性和根管的不可视性,根管机械预备过程中容易出现根管内台阶、偏移、髓室底或根管壁穿孔、器械分离、术后疼痛等并发症。了解根管机械预备并发症的发生原因和处理方法,有助于临床有效预防和处理并发症,减少并发症造成的损伤及其不良后果。本文对根管机械预备常见并发症的原因、预防及处理方法进行系统回顾和分析,以期提高临床医师对根管机械预备并发症的认识。
Root canal preparation is one of the important procedures in root canal treatment as well as one of the key factors to the success of root canal treatment. It consists root canal cleaning and shaping, and further provides a favourable condition for root canal obturation. Because of the complexity and irregularity of root canal system, complications may occur during the root canal mechanical preparation, such as root canal ledges, transportations, perforations, instruments separating and flare ups. Understanding the reason and management of root canal mechanical preparation complications is helpful to prevent its occurrence and to reduce the unfavourable prognosis as well. This article discusses and systematically analyzes the reason, prevention and management of the complications in root canal mechanical preparation, in order to enhance the awareness of clinicians on these complications.
