【摘要】：目的研究低功率微波对中性氧化电位水消毒口腔印模材料效果的影响,为探求口腔印模有效的消毒方法提供实验参考。方法采用载体定量杀菌试验方法,对微波与中性氧化电位水联合作用消毒口腔印模材料的效果进行观察。结果以140 W低功率微波联合中性氧化电位水对大肠杆菌作用2 min,对金黄色葡萄球菌和白色念珠菌作用3 min,杀灭对数值均3.00;对枯草杆菌黑色变种芽孢作用5 min,杀灭对数值3.00。中性氧化电位水单独浸泡3 min,对大肠杆菌杀灭对数值3.00,但对金黄色葡萄球菌和白色念珠菌杀灭对数值则3.00。单独低功率微波照射作用3 min,对上述3种细菌杀灭对数值均3.00。结论低功率微波对中性氧化电位水杀灭不同微生物均有显著增效作用,可用于口腔印模消毒。
[Abstract]:Objective to study the effect of low power microwave on the efficacy of neutral oxidized potential water in disinfection of oral impression materials. Methods the efficacy of microwave combined with neutral oxidation potential water in disinfection of oral impression materials was observed by carrier quantitative germicidal test. Results when the Escherichia coli was exposed to 140W low power microwave combined with neutral oxidizing potential water for 2 min, Staphylococcus aureus and Candida albicans were exposed for 3 min, the logarithmic values were 3.00, and 3.00 for 5 min for spores of Bacillus subtilis var. nigra and 3.00% for spores of Bacillus subtilis var. nigra. Neutral oxidized potential water soaked alone for 3 min killed the logarithmic value of Escherichia coli 3.00, but to Staphylococcus aureus and Candida albicans 3.00. When exposed to low power microwave alone for 3 min, the logarithmic values of the three bacteria were all 3.00. Conclusion low power microwave has a significant synergistic effect on killing different microorganisms in neutral oxidized potential water and can be used in oral impression disinfection.
