摘　　要：目前,国内临床上多使用体积分数为3%的过氧化氢和生理盐水交替冲洗根管,但是这2种溶液存在许多缺陷。次氯酸钠具有较强的杀菌性和组织溶解性,所以在国外被普遍应用于根管冲洗中。目前,国内也正逐步将次氯酸钠应用于临床,但是却很少使用螯合剂作为根管常规的冲洗液。螯合剂的优势日益受到关注,螯合剂具有去除根管预备中形成的玷污层的优势,但不能有效溶解残留的牙髓,次氯酸钠具有有效溶解有机残髓的作用,两者联合应用能达到相互补偿、相互增效的作用,是目前用于玷污层去除的有效组合。本文对螯合剂的研究进展作一综述,以期推广其在国内临床上的应用。There are many defects in the alternating use of 3% hydrogen peroxide and saline during and after root canal instrumentation in most of hospitals in China. Sodium hypochlorite is widely used abroad in endodontics because of its strong antimicrobial action and tissue solvent activity. And now, sodium hypoehlorite is used in China step by step, but chelating agent is seldom used as root canal irrigation in endodontics. Chelating agent＇s advantage has been focused recently which is capable of removing the smear layer formed during root canal in- strumentation, but is inefficient in dissolving pulpal remnants while sodium hypochlorite can. It is widely accepted that the most effective method to remove smear layer is to irrigate the root canal with chelating agent followed by sodium hypochlorite. This paper reviewed the research process in aspects of chelating agent used as root canal irrigation, contributing to popularize its internal clinical application.
