摘　　要：目的观察过氧化氢每日消毒对口腔综合治疗台水路(DUWL)微生物污染的控制效果。方法通过现场采样和细菌定量检测方法,对某三甲口腔专科医院牙体牙髓科用过氧化氢每日消毒DUWL的效果进行观察。结果未经消毒的对照组诊疗用水中细菌总数为1×10^(4)cfu/mL。采用浓度为30 g/L过氧化氢每日对DUWL进行消毒处理后,三用枪、高速手机和漱口水的水样卫生质量平均合格率分别为80.2%、83.3%和87.5%。结论每日坚持用过氧化氢对DUWL进行消毒,可以有效降低口腔治疗用水中细菌数,提高水质合格率。Objective To observe the effect of hydrogen peroxide on controlling microbial contamination daily in dental unit waterlines(DUWL).Methods By using on-site sampling and quantitative bacterial detection methods,the effect of daily disinfection of DUWL with hydrogen peroxide in tooth and dental pulp department of a tertiary stomatology-specialized hospital was observed.Results The average total bacterial count in the untreated diagnosis and treatment water of control group was 1×10^(4)cfu/mL.After daily disinfecting DUWL with a concentration of 30 g/L hydrogen peroxide,the average qualified rates of the hygiene quality of the water samples from three ways syringe,high-speed handpiece,and mouthwash were 80.2%,83.3%,and 87.5%,respectively.Conclusion Daily disinfection of DUWL with hydrogen peroxide can effectively reduce the bacterial count in oral treatment water and improve the qualified rate of water quality.
