摘　　要：根管预备过程中,机械预备会在根管壁表面和牙本质小管内形成玷污层,玷污层清理不足可导致根管治疗最终失败。因此许多学者以去除根管内玷污层为目的,对根管冲洗液的清理效果进行了大量广泛的研究,目前主流清理玷污层的冲洗液之一就是有机酸及以有机酸为主要成分的复合型冲洗液。本文就目前有机酸冲洗液对根管玷污层清理效果的研究进展作一综述,提示以有机酸为主的复合型冲洗液、马来酸和鞣酸冲洗液可作为去除玷污层的优先选择,为临床牙髓病治疗提供一定的参考。A smear layer is produced during the instrumentation,which could be found both on the canal wall and into some dental tubules.Insufficient cleaning of the smear layer could result in failure of root canal therapy finally.Therefore,smear layer removing ability of root canal irrigation solutions had been researched by many scholars.Recently,one of the main root canal irrigation solutions for smear layer removal was organic acids and organic acid-based mixtures irrigation solutions.This article summarizes the current research progress on smear layer removing ability of organic acid irrigation solutions.It is suggested that the organic acid-based mixtures irrigation solutions,maleic acid,and tannic acid could be used the priority to remove the smear layer,which provides some reference for the clinic endodontic treatment.
