摘要
目的评价微波消毒法对口腔石膏模型的消毒效果。方法用细菌定量检测和基因扩增荧光定量技术,对微波照射消毒口腔石膏模型的效果进行了观察。结果用输出功率120 W微波炉对染菌口腔石膏模型进行照射消毒。照射5 min,可完全杀灭污染在口腔石膏模型上的枯草芽孢杆菌,并可完全灭活污染在口腔石膏模型上的乙型肝炎病毒DNA。结论普通家用微波炉在满功率条件下照射5 min,可有效杀灭污染在口腔石膏模型上的细菌和病毒。
Objective To evaluate of microwave disinfection effect for clinical plaster model.Methods Bacterial quantitative detection and fluorescence quantitative gene amplification technology were used to evaluate the disinfection efficacy of microwave irradiation for plaster model.Results The output power of microwave oven irradiation was 120W.After exposed for 5 min,Bacillus subtilis spores contaminated on the plaster model can be completely killed,and Hepatitis B virus DNA contamination in dental plaster model can be completely inactivated.Conclusion The common household microwave oven in full power conditions irradiate for 5 min,can effectively kill bacteria and virus polluted on the oral cavity plaster model.
