Aim of the study was to compare 4 different methods of sterilizing endodontic files in dental practice.
MATERIALS & METHODS: The present study was performed on 100 K-files, 21 mm long and of size 25. Of these, 20 files were taken as control group, and the remaining 80 files were divided into 4 groups of 20 files each and they were tested for the efficacy of sterilization with different methods: Autoclave, glass bead, glutaraldehyde and CO2 laser.
The study showed that the files sterilized by autoclave and lasers were completely sterile. Those sterilized by glass bead were 90% sterile and those with glutaraldehyde were 80% sterile.
The study concluded that autoclave or laser could be used as a method of sterilization in clinical practice and in advanced clinics; laser can be used also as a chair side method of sterilization.

本研究的目的是比较牙科实践中4种不同的根管锉消毒方法。
本研究使用了100根21毫米长、型号为25的K型根管锉。其中，20根锉作为对照组，其余80根锉分为4组，每组20根，分别用不同方法测试消毒效果：高压灭菌器、玻璃珠、戊二醛和二氧化碳激光。
研究表明，经高压灭菌器和激光消毒的锉完全无菌。经玻璃珠消毒的锉90%无菌，经戊二醛消毒的锉80%无菌。
本研究得出结论，高压灭菌器或激光可作为临床实践和先进诊所的消毒方法；激光也可作为椅旁消毒方法。如何引用本文：Raju TB, Garapati S, Agrawal R, Reddy S, Razdan A, Kumar SK. 用四种不同消毒方法对根管锉进行消毒以预防交叉感染——一项体外研究。《国际口腔健康杂志》2013年；5(6):108 - 12 。
