摘要
手用根管锉通常又称为手用锉,是一种在根管治疗中通过冠根向进出运动来清理、成形根管的器械。现代根管治疗技术中根管预备以镍钛器械为主,但手用器械仍然发挥了不可替代的作用,包括根管探查、根管疏通、根尖通畅、根管长度测量等。本文回顾了手用锉的发展,制作材质由最初的碳钢到不锈钢,再到镍钛,制作标准由最初的不统一到国际标准化组织(ISO)标准,再到各类改良器械问世,手用锉越来越好地满足各类临床需要,成为根管治疗中不可或缺的一类器械。选择合适的手用锉,结合正确的使用方式,做到充分冲洗清洁、超声荡洗,避免包括术后肿胀、根管侧穿、器械分离、台阶等并发症的发生,已成为根管治疗的必修课。
Root-canal hand instruments,often referred to as hand files,are tools utilized in endodontic therapy to clean and enlarge the root canal through a push-pull motion from the crown to the root.In modern endodontic techniques,nic-kel-titanium instruments predominantly facilitate root canal preparation.However,hand instruments continue to play an irreplaceable role in various procedures,including canal exploration,canal patency,apical clearance,and root canal length measurement.This article reviews the evolution of hand files,tracing the development of materials from the initial use of carbon steel to stainless steel and now to nickel-titanium.The manufacturing standards have progressed from irregularities to ISO standards,alongside the emergence of various modified instruments.As a result,hand files increasingly meet diverse clinical needs,establishing themselves as indispensable tools in root canal therapy.Selecting appropriate hand instruments and employing proper techniques—such as thorough irrigation;and cleaning,along with ultrasonic irrigation;helps prevent complications such as postoperative swelling,root canal perforation,instrument separation,and ledge formation.This has become an essential component of root canal therapy.
