摘　　要：目的 比较5%过氧化氢银离子(HPSI)消毒剂持续与定期消毒对控制口腔综合诊疗台水路(DUWL)污染的效果。方法 选择某口腔医院20台DUWL,将其随机分为定期消毒组(1次/周)与持续消毒组(1次/d,每日诊疗结束后),每组10台,2组均采用5%过氧化氢银离子消毒剂进行消毒,检测消毒前及消毒后第1-7天高速手机、三用喷枪及漱口水出水口水样细菌种类及菌数变化。结果 本次试验共分离菌株45株,占比前3位的为少动鞘氨醇杆菌(33.33%)、唐菖蒲伯克霍尔德菌(20.00%)和皮氏罗尔斯顿菌(17.78%);消毒前,消毒后第1~2天高速手机、三用喷枪及漱口水出水口水样细菌数量差异无统计学意义;消毒后第3~7天,持续消毒组高速手机、三用喷枪、漱口水出水口水样细菌数量低于定期消毒组(P<0.05)。结论 与持续消毒相比,HPSI消毒剂每间隔2 d进行1次定期消毒具有更高的应用价值。Objective To compare the disinfection effects of continuous and regular disinfection with 5%hydrogen peroxide-silver ion disinfectant on controlling the pollution of dental unit waterlines (DUWLs).Methods Twenty DUWLs in a hospital were selected as the research objects.They were randomly divided into a regular disinfection group (once a week) and a continuous disinfection group (once a day,after the daily diagnosis and treatment),with10 units in each group.Both groups were disinfected with 5%hydrogen peroxide-silver ion disinfectant.The changes in the types and numbers of bacteria in water samples from high-speed handpieces,three-in-one spray guns,and mouthwash outlets were detected before disinfection and on the 1~(st)-7~(th) days (d1-d7) after disinfection.Results A total of 45 strains were isolated in this experiment.The top three in proportion were Sphingobacterium paucimobilis(33.33%),Burkholderia gladioli (20.00%),and Ralstonia pickettii (17.78%);before disinfection,on d1 and d2 after disinfection,there was no statistical significance in the differences in the number of bacteria in water samples from high-speed handpieces,three-in-one spray guns,and mouthwash outlets between the two groups (P>0.05);on d3-d7 after disinfection,the number of bacteria in water samples from high-speed handpieces,three-in-one spray guns,and mouthwash outlets in the continuous disinfection group was lower than that in the regular disinfection group,and the difference was statistically significant (P<0.05).Conclusion Compared with continuous disinfection,regular disinfection once every 2 days has higher application value.
