目的探讨口腔器械清洗液的种类及器械投放量对清洗效果的影响。方法选择300件崭新口腔齿类器械在血库血中浸泡24 h、干燥1 h后随机分为多酶组、健之素组、自来水组各100把,分别采用多酶清洗液、健之素清洗液及自来水浸泡、人工刷洗及冲洗,均采用目测法和杰力试纸法检测。对多酶组、健之素组清洗不合格器械按同等配比清洗液再分批超声振荡清洗,同法检测。结果人工刷洗器械,目测法、杰力试纸检测合格率多酶组最高,健之素组次之(均P<0.017);杰力试纸检测合格率显著低于目测法(P<0.01);超声振荡再清冼多酶组可投放量相对多于健之素组。结论多酶清洗液清洗口腔器械效果优于健之素清洗液,杰力试纸检测清洗后口腔器械残留血迹较目测法精确,控制超声酶液内投放器械量有利于提高器械清洗效果。
Objective To investigate the effect of cleaning instruments on the type of oral fluid and the dose of instruments. Methods A total of 300 new dental instruments were soaked in blood for 24 h. After drying for 1 h, they were randomly divided into multi-enzyme group, Jianzheng Su group and water group. Each group was treated with multi-enzyme cleaning solution, Immersion of liquid and tap water, manual scrubbing and flushing are all carried out by visual inspection and Jieli test paper method. On the enzyme group, Jianzhisu group failed to wash the device according to the same ratio of cleaning solution and then sub-batch ultrasonic cleaning, the same test. Results The results of artificial brushing test, visual inspection method and Jieli test paper showed that the highest pass rate was in multi-enzyme group and the second in Jianzhisu group (P <0.017). The passing rate of Jieli test paper was significantly lower than that of visual inspection (P <0.01) Oscillation and then clear more enzyme groups can be put relatively more than Jianzhisu group. Conclusions Multi-enzyme cleaning solution is superior to Jianzheng cleaning solution in cleaning oral instruments. Jieli test strip is more precise than visual inspection method in detecting oral residual blood after cleaning. Controlling the amount of instruments in ultrasound enzyme solution is helpful to improve the cleaning effect.
