摘　　要：目的观察次溴酸对口腔综合治疗台水路系统(dental unit waterlines,DUWLs)的消毒效果。方法选取医院DUWLs,包括三用喷枪、牙科手机、水杯注水器各20台,将3种设备以1~20编号排列,1~10号设备纳入实验组,11~20号设备纳入对照组。对照组不进行DUWLs消毒,实验组使用次溴酸消毒。分别于每日诊疗前,冲洗3min后进行水样检测,采集时间为第0、1、2、3、4、5、8、10、15、20、25、30天,共采样12次。构建广义估计方程,比较两组不同时点手机插口部位,水杯出水部位,三用枪插口部位菌落计数;比较DUWLs水样合格率。结果构建广义估计方程,对两组手机插口部位,水杯出水部位,三用枪插口部位菌落计数进行截距、组别、时点、组别×时点的固定效应的显著性检验,两组数据在不同时点间变化差异有统计学意义(P<0.05)。两组首次开诊前实验组三用枪插口部位菌落计数较对照组多16800,差异有统计学意义(P<0.05);对照组第30天时菌落计数较首次开诊前减少29000;实验组第30天时菌落计数减少量较对照组多35250,差异有统计学意义(P<0.05)。两组首次开诊前两组手机插口部位菌落计数差异无统计学意义(P>0.05);对照组第30天时菌落计数较首次开诊前减少86900;实验组第30天时菌落计数减少量较对照组多16350,差异无统计学意义(P>0.05)。两组首次开诊前水杯出水部位菌落计数比较差异无统计学意义(P>0.05);对照组第30天时菌落计数较首次开诊前减少25550;实验组第30天时菌落计数减少量较对照组多11800,差异有统计学意义(P<0.05)。实验组诊疗前、冲洗3min后手机插口部位,水杯出水部位,三用枪插口部位合格率均高于对照组,差异有统计学意义(P<0.05)。结论使用次溴酸进行DUWLs消毒能够减少菌落计数,提高水样合格率。Objective To observe the disinfection effect of hypobromic acid on the oral comprehensive treatment table water system(DUWLs).Methods The research equipment was selected from hospital DUWLs,including 20 sets of three purpose spray guns,dental mobile phones,and water cup injectors.The three types of equipment were arranged in numbers 1-20,with devices 1-10 included in the experimental group and devices 11-20 included in the control group.The control group was not disinfected with DUWLs,while the experimental group was disinfected with hypobromic acid.Before daily diagnosis and treatment,water samples were collected for 3 minutes after rinsing.The collection time was on the 0th,1st,2nd,3rd,4th,5th,8th,10th,15th,20th,25th,and 30th days,with a total of 12 samples taken.The generalized estimation equation was constructed to compare the colony count of the cell phone jack,the water cup outlet and the three gun sockets of the two groups at different time points.The qualified rate of DUWLs water samples was compared.Results The generalized estimation equation was constructed to test the significance of the fixed effect of intercept,group,time point,group time point for the bacterial count of the two groups of mobile phone jack parts,the water cup outlet parts and the three gun jack parts.The variation difference between the two groups of data at different time points was statistically significant(P<0.05).Before the first treatment,the number of colonies in the experimental group was 16800 more than that in the control group(P<0.05).On the 30th day,the bacterial count in the control group decreased by 29000 compared to before the first consultation.On the 30th day,the decrease in bacterial count in the experimental group was 35250 more than that in the control group(P<0.05).There was no statistical significant difference in the number of colonies at the cell phone socket between the two groups before the first diagnosis(P>0.05).On the 30th day,the bacterial count in the control group decreased by 86900 compared to before
