摘　　要：根管治疗术是目前牙髓病及根尖周病最为有效的治疗方法,在临床上广为应用。但根管治疗失败仍时有发生,这就需要去除原有充填材料,重新进行根管预备、消毒和充填。牙胶是目前应用最为普遍的充填材料。文章将对根管再治疗过程中原有牙胶充填材料去除的方法、效果及安全性做一概述。The root canal therapy is the most effective treatment for pulpal and periapical disease, but failure oc- curred occasionally. Root canal retreatment is the best choice to save the teeth at this moment. The success of root canal re- treatment depends highly on complete removal of previous root filling material and infection tissue, and formation of tight three-dimensional closure. This paper will discuss the methodand effectiveness of intracanal gutta-percha removing.
