现代根管治疗概述

A History Review of Current Contemportary Root Canal Therapy

现代根管治疗从19世 纪末至今经历了非标准化时期、标准化时期和变革期3个发展阶段。各阶段的特点主要体现在根管器械的设计和临床治疗技术上。根管器械在制造材料及设计上的改进,使根管预备更具有可控性,并提高了预备效率。近年来逐步深入技术和以热牙胶为主的充填技术已广泛应用于临床。手术显微镜和根管内窥镜在根管治疗领域的应用,使根管治疗从经验性和盲目性走向直观性,扩大了根管治疗的适应范围,提高了治疗的成功率。

The development of root canal therapy was divided into non-standardized. standardized and reform stages according to the design of endodontic instruments and techniques. The great improvement on Endodontic instruments made root canal preparation easier and more effective. Crown-down pressureless technique and warm gutta-percha technique have been widespreadly used in clinic today. The surgical operating microscope and endoscope provide increased magnification and properly focused light which allows doctors to view areas that otherwise would not be seen during conventional root canal treatment. With the application of microscope, a higher degree of clinical success could be anticipated.
