【摘要】 根管系统的细菌污染被认为是牙髓和根尖周病变发展的主要病因。根管系统有效的化学机械预备是根管治疗成功的重要步骤。为了达到更好的消毒效果,不同的冲洗技术应用于根管治疗中,包括根管刷、声波、超声荡洗等。近年来,激光活化根管冲洗亦应用于临床。基于现阶段的研究,激光活化冲洗的效果(尤其是Er:YAG激光的使用)由于特定的空化现象和声流的诱导而变得更加有效。本文就激光活化根管冲洗的研究进展进行综述,为临床医生提供根管治疗冲洗方案的选择及比较。更多还原

【Abstract】 Bacterial infection of the root canal system is one of the main causes of apical periodontitis.Chemomechanical preparation of root canal through a combination of mechanical instrumentation and antibacterial irrigation is the critical stage in canal disinfection,and is principally directed toward the elimination of microorganism from the root canal system.Consequently,advanced disinfection strategies are developed and tested in Endodontics,including agitation with brush,gutta-percha cones,sonic and ultrasonic devices.Another way to activate irrigation solutions is laser activated irrigation(LAI).Based on present-day research it appears that the efficacy of laser activation(especially with Erbium lasers) can be more efficient thanks to the induction of specific cavitation phenomena and acoustic streaming.更多还原
