摘　　要：目的探讨2种消毒法对口腔3种常用印模材料的消毒效果及模型精度的影响。方法依据统一的标准制作藻酸盐、藻酸盐琼脂及硅橡胶3种不同材料的口腔印模。分别以含量氯消毒液浸泡和雾化酸I生氧化电位水进行消毒。比较两种消毒方法对3种印模的消毒效果及模型精度的影响。结果含氯消毒液浸泡30min以及雾化酸陛氧化电位水消毒30min对3种材料的印模均可达到有效消毒效果，对染菌的最低杀灭率为99．48％。含氯消毒液浸泡法对藻酸盐印模与硅橡胶印模的精度无显著影响，但对藻酸盐琼脂混合材料的印模精度有显著影响。雾化酸性氧化电位水消毒对3种材料的印模精度无显著影响。结论雾化酸l生氧化电位水适合于临床3种材料印模的消毒，含氯消毒液浸泡法适合于藻酸盐、硅橡胶印模，但不适于藻酸盐琼脂混合印模的消毒。Objective To investigate the influence of two disinfectants methods on disinfection efficiency and model precision of dental impression. Methods Alginate impressions, alginate and agar complex impressions and silicon rubber impressions were made according to a unified standard. Chlorinous disinfectant solution and acidic oxidative potential water were used to disinfect the infected impressions. The influence of two disinfectants on disinfection efficiency and model precision of dental impression was compared. Results Two disinfectants for 30 minutes had significant disinfection effect on these three kinds of impressions. The effective rate reached 99.48%. Chlorinous disinfectant solution had no significant influence on the model precision of alginate impressions and silicon rubber impressions,but had significant influence on the model precision of alginate and agar complex impressions. Acidic oxidative potential water did not influence the model precision of the three dental impressions. Conclusions Acidic oxidative potential water can be used to disinfect the three dental impressions. Chlorinous disinfectant solution can be used to disinfect alginate impressions and silicon rubber impressions, but cannot be used to disinfect agar complex impressions.
