摘　　要：由于根管系统的复杂性,传统的根管预备器械与冲洗剂难以达到完全清理根管的目的。Er∶YAG激光联合根管冲洗剂使用,既可以采取更保守的根管预备,又能增强去除玷污层、开放牙本质小管和杀菌的能力,有利于根管封闭剂和根管内黏结剂的渗透而减少微渗漏;且在一定的激光参数范围内,其不会引起冲洗剂的根尖渗出;产热作用也极小,不会引起根尖周组织损伤。因此,Er∶YAG激光的应用能使根管预备过程变得简单、高效、安全。本文综述了Er∶YAG激光在根管治疗中的应用研究进展。Due to the morphology of root canal systems, complete debridement and disinfection can＇t be done by traditional mechanical instrumentation and irrigants. Er：YAG laser based irrigation may allow more conservative root canal preparation , remove smear layer, open the dentinal tubules and disinfect more effectively while using conventional irrigants. Hence, it is used to reduce microleakage as the opening dentinal tubules facilitate the penetration of sealer and adhesives. Within a certain range of laser parameters, the apical extrusion of root canal irrigants will not occur while thermal influence on periapical tissue is minimal. So the application of Er：YAG laser in root canal therapy enables the treatment to become simple, effective, and safe.
