每人次更换贮水罐与蒸馏水对减少口腔科水系统污染效果的研究

目的 探讨降低口腔科治疗椅水系统的细菌微生物污染方法.方法 将口腔科治疗的120例患者随机分为对照组和观察组各60例;对照组采用常规方法24 h更换贮水罐与蒸馏水;观察组采用每人次更换贮水罐和蒸馏水.比较2种方法治疗椅水系统细菌微生物污染数量的变化.结果 对照组60份口腔治疗椅系统水样品合格率为68.33%.观察组60份水样品合格率为100%,2组比较有显著差异.结论 每人次更换贮水罐和蒸馏水明显降低微生物数量,是控制口腔科治疗椅水系统细菌微生物污染的有效措施.

Research about prevent contamination of water system in department of stomatology by replace holding tank of water and distilled water for each person

Objective To know a kind of method to prevent contamination of water system in department of stomatology. Methods Divided 120 patients with dental diseases into the control group and the observation group randomly, there were 60 cases in each group. Replace the holding tank of wa-ter and distilled water per 24 hours was used in the control group, while the method of replace the hold-ing tank of water and distilled water for each person was used in the observation group, and then com-pared the contamination condition of water system between the two groups. Results The percent of pass of water system in the observaiton group was 100%, which significant higher than the 68.33% in the control group. Conclusions Replace the holding tank of water and distilled water for each person is a kind of method to avoid contamination of water system in department of stomatology.
