Root canal debridement, which includes the removal of infected tissues and microbial biofilms, is considered the corner stone of root canal treatment. Chemical adjuncts play a multitude of functions in this regard, as tissue solvents, antimicrobial agents and for removing the smear layer. These adjuncts (irrigants) are usually delivered using a syringe and needle. With increasing knowledge of the complexity of root canal anatomy and tenacity of microbial biofilms, the need for strategies that potentiate the action of these irrigants within the root canal system cannot be overemphasized. Several such activated irrigation strategies exist. The aim of this review is to comprehensively discuss the different irrigant activation methods from the context of clinical studies.
根管清创术，包括清除感染组织和微生物生物膜，被认为是根管治疗的基石。化学辅助剂在这方面发挥着多种作用，可作为组织溶剂、抗菌剂以及用于去除玷污层。这些辅助剂（冲洗剂）通常通过注射器和针头输送。随着对根管解剖结构复杂性和微生物生物膜韧性的认识不断增加，强调增强这些冲洗剂在根管系统内作用的策略的必要性再怎么强调也不为过。存在几种这样的活化冲洗策略。本综述的目的是从临床研究的角度全面讨论不同的冲洗剂活化方法。
