C形根管(C-shaped root cana1)系统是根管横截面呈“C”形的根管系统,常发生于下颌第二恒磨牙。C形融合根管的解剖结构较为复杂。常规根管预备方法往往难以彻底有效地对其清理和成形,从而影响治疗效果。对于C形根管的预备目前还没有规范化的预备技术研究的报道。本文就C形根管系统的基本特征及其预备研究的新进展作一综述。
C-shaped root canal (C-shaped root cana1) system is a root canal cross-section was “C” -shaped root canal system, often occurs in the mandibular second permanent molars. C-shaped fusion root canal anatomy is more complicated. Conventional root canal preparation methods are often difficult to completely and effectively clean and shape, thus affecting the treatment effect. For the preparation of C-shaped root canal is currently no standardized preparation technology research reports. This article reviews the basic features of the C-shaped root canal system and its new progress in preparative research.
