摘要
目的比较牙钻手机机械清洗与手工清洗的效果。方法将污染程度相同的牙钻手机80支随机分成两组,每组40只,一组采用全自动清洗机清洗,另一组采用手工清洗,两组均按标准流程操作,清洗后采用ATP生物荧光法检测清洗效果。结果 ATP生物荧光检测相对发光单位(RLU)平均值分别为:机械清洗组为9,手工清洗组为41,两组均低于生产厂家提供的RLU≤45的推荐值,两组差异有统计学意义(P<0.05)。结论机械清洗的效果优于手工清洗,建议消毒供应中心采用机械清洗法清洗牙钻手机,确保清洗质量。
Objective Comparing the dental handpiece＇s cleaning effect between manual cleaning and machine cleaning. Methods Eighty same contaminated dental handpieees were randomly divided into experimental group and control group, each group contains 40 pieces. The experimental group was treated by full automatic washing machine, and the control group was cleaned manually. The cleaning method was conducted according to the operations process standard, then ATP bioluminescence was used to test the cleaning results. Results Average relative light units CRLU） by ATP bioluminescence detection were as follows： Experimental group was 9, control group was 41. The two groups were less than the recommended RLU value provided by the instrument manufacturer（RLU≤45）. There was signifi- cant difference between the two groups （P〈0.05）. Conclusion The cleaning quality of the experimental group was better than that of control group. It is recommended that the central sterile supply department should clean dental handpieces by machine to ensure the cleaning effect and maintain the quality.
