摘要
目的探讨两种医用清洗剂对口腔科磷酸锌水门汀填充器预处理的效果。方法选取100件全新的口腔科水门汀填充器,通过模拟临床口腔科器械污染的场景使其达到中度及以上污染,分为碱性含酶组和多酶组,每组50件。两组均采用手工刷洗联合全自动喷淋式清洗机的清洗方法。应用肉眼裸视检测、十倍带光源放大镜检测和残留蛋白定量检测评价两组预处理的效果。结果在肉眼裸视检测和十倍带光源放大镜检测中,碱性含酶组清洗合格率高于多酶组,差异有统计学意义(P<0.05);在残留蛋白定量检测中,两组清洗合格率比较差异无统计学意义(P>0.05)。在肉眼裸视检测和十倍带光源放大镜检测中,碱性含酶组器械3个部位清洗合格率均高于多酶组,但只有手柄螺纹表面清洗合格率比较差异有统计学意义(P<0.05);碱性含酶组器械3个部位清洗合格率比较差异无统计学意义(P>0.05),多酶组器械3个部位清洗合格率比较差异有统计学意义(P<0.05)。结论相较于多酶清洗剂,碱性含酶清洗剂在口腔科磷酸锌水门汀填充器预处理中的效果更好。
Objective To compare the efficacy of alkaline enzyme-containing versus multi-enzyme cleaner for pre-cleaning dental zinc phosphate cement fillers.Methods One hundred new dental cement fillers were selected and contaminated to moderate-to-heavy levels by simulating clinical contamination,and divided into the alkaline enzyme-containing group and the multi-enzyme group,with 50 cases in each group.The two groups underwent manual brushing followed by automated spray-type washer-disinfector cleaning.The efficacy of the two groups of pre-cleaning were evaluated by naked-eye visual detection,10×illuminated magnification and residual protein quantification.Results The alkaline enzyme-containing group demonstrated significantly higher pass rates than the multi-enzyme group by naked-eye visual detection and 10×illuminated magnification(P<0.05),while there was no statistically significant difference in the residual protein quantification between the two groups(P>0.05).The qualified cleaning rates of the three parts of the instruments in the alkaline enzyme-containing group were all higher than those in the multi-enzyme group,but only the qualified cleaning rate of the handle threaded surface was statistically significant(P<0.05).There was no statistically significant difference in the cleaning qualification rates of the instruments three parts of the alkaline enzyme-containing group(P>0.05),while there was statistically significant difference in the cleaning qualification rates of the instruments three parts of the multi-enzyme group(P<0.05).Conclusion Compared with the multi-enzyme cleaner,alkaline enzyme-containing cleaner has better effects in the pre-cleaning of zinc phosphate cement fillers.
