摘要
根管再治疗是通过根管途径从冠方去除根管内原有充填材料,对感染根管进行再预备、清理和充填,其中根管内充填物的有效去除是再治疗成功的基础。应用手动器械、机用再治疗镍钛器械等进行根管充填物去除的技术已广泛应用于临床,但为了进一步提高根管充填物去除率,根管充填物去除辅助技术应运而生,即在常规机械化器械去除充填物的基础上补充应用自调节锉、XP-Endo系列锉、动能冲洗系统、激光以及连续根管外冲洗等技术。本文就近年来新型辅助技术的应用与发展作一综述,旨在为提高临床根管充填物去除效果提供参考。
Root canal retreatment involves removing the original infected filling materials,preparing,cleaning,and filling the root canal again in a crown down direction.The effective removal of filling materials is the basis of successful retreatment.Techniques of root filling removal using manual instruments and mechanical Ni-Ti retreatment have been widely used in clinical.For further improvement in the rate of root filling removal,supplementary techniques have been developed on the basis of conventional mechanical system.Some examples include using self-adjusting file,XP-Endo files,kinetic energy irrigation system,laser and continuous flushing out of the canal to remove the filling materials.This review summarizes the application and development of new supplementary techniques to provide reference for improving the rate of root filling material removal in clinical work.
