摘　　要：目的：比较手工注油和自动注油机注油方法养护牙科手机的效果并完善手工注油流程。方法抽取使用后牙科高速涡轮手机600支，清洁干燥后随机分为6组，A组手工注油，B1、B2、B3、B4组分别于手工注油后加压力气枪吹清手机内腔1～2，4～5，9～10，14～15 s，C组自动注油机注油。通过显微镜下观察手机涡轮转子表面注油液灭菌后痕迹、天平测量涡轮转子表面存留注油液重量、测量手机包装灭菌纸塑袋油渍面积来评价注油养护效果。结果6组手机涡轮转子表面均可见润滑油灭菌后留下的痕迹。手机涡轮转子表面存留注油液量的比较：C组与A、B1、B3、B4组之间差异有统计学意义（ P＜0．05）；C组与B2组之间差异无统计学意义（P＞0．05）。手机包装灭菌纸塑封袋上显示油渍面积的比较：C组与A、B1、B3尾部、B4组面积之间差异有统计学意义（P＜0．05）；C组与B2、B3组头部面积之间差异无统计学意义（ P＞0．05）。结论单纯手工注油没有自动注油机注油的养护效果好，完善手工注油流程，即手工注油后加压力气枪吹清手机内腔4～5 s，可达到与自动注油机注油相近的养护效果。Objective To study the effect of maintenance of handpiece by manual filling and machine oil injection method , so as to perfect the manual filling process .Methods Totals of 600 extraction used handpiece after cleaned and dried were randomly divided into six groups .Group A was given manual filling , Group B1 ,B2 ,B3 ,B4 were given manual filling and pressure air gun to blow the handpiece cavity for 1-2,4-5, 9-10,14-15 seconds.Group C used oil filling machine .To evaluate the effect of maintenance of handpiece , the turbo-rotors bearing surface traces after sterilization with a microscope were observed , and the remaining oil injection weight was weighed and the oil area of handpiece packaging sterilization bags was measured . Results Turbo-rotors bearings surfaces were visible traces of lubricating oil left after sterilization for all the six groups.The comparison results of the remaining oil weight of turbo-rotors bearing surfaces showed that group C and group A, B1, B3, B4 were significantly different （P〈0.05）, but group C and group B2 had no significant difference （P〉0.05）.The comparison results of the oil area of handpiece packaging sterilization bags showed that group C and group A, B1, B3 tail, B4 had significant differences （P〈0.05）, while group C and group B2, B3 head had no significant difference （P〉0.05）.Conclusions The effect of maintenance of machine oil is better than pure manual filling .The perfecting manual filling process of maintenance of handpiece , which is manual filling , which using the pressure air gun to blow the handpiece cavity for 4-5 seconds , can achieve the equivalent maintenance effect with the machine oil injection .
