摘　　要：目的研究消毒锅预热、物品摆放位置及内壁清洁对消毒效果的影响。方法120只临床使用过的牙科涡轮手机,根据高压蒸汽灭菌器处理程序分为4组,每组30只手机,分别置于高压蒸汽灭菌器的内部、中部和外部;应用芽胞检测指示剂对其消毒灭菌效果进行检测。结果高压蒸汽灭菌器的不同处理方法对手机灭菌效果差异有统计学意义(P<0.05);手机摆放位置对高压蒸汽灭菌器灭菌效果无影响(P>0.05)。结论使用压力灭菌器前要用0.5%含氯消毒剂擦拭内壁及温控探头,预热30 min,才能达到理想的灭菌效果。OBJECTIVE To study the influence to the sterilizing effect of these factors, which were preheating the sterilizer, the positions of the articles placed and the cleanness of the internal walk METHODS A total of 120 clinical used dental handpieces, according to the high-pressure steam sterilizer disposal procedure, were divided into four groups, with 30 handpieces in each group. Those only with high-pressure steam sterilizer process were chosen as the control group. Preheating 30 minutes, wipping the internal wall with 0. 5% chlorine disinfectant before using high-pressure steam sterilizer and acting both of two steps were all chosen as the experimental groups. Each group was put in the interior, middle and exterior of the high-pressure steam sterilizer separately. The Rapid Readout Biological Indicators （3M Attest, the USA） were used to test the sterilizing effect. RESULTS The different methods of the high-pressure steam sterilizer had the significant differences to the handpieces sterilizing effect （P〈0. 05）. There were no differences among the positions of handpieces to achieve good sterilizing effect （P〉0.05）. CONCLUSIONS To achieve ideal sterilization, it is suggested to wipe the internal wall and the temperature control probe head with 0.5 % chlorine disinfectant and preheat the sterilizer for 30 minutes before put handpieces in the high-pressure steam sterilizer.
