摘　　要：目的 调查苏州市医疗机构口腔综合治疗台水路微生物污染情况,分析其影响因素。方法 设计调查问卷,以现场询问的方式收集医院口腔科或口腔诊所基本信息及水路消毒方式、频次等信息,采集水样进行菌落计数,根据是否超标分为超标组和未超标组,比较医疗机构基本信息及水路消毒情况。结果 共调查111家口腔诊疗机构,采集水样393份,其中合格202份,合格率为51.40%。不同等级医疗机构手机水的菌落总数差异有统计学意义(P<0.05)。超标组与未超标组医疗机构在治疗台日均诊疗量、水源类型及供水模式的分布具有统计学差异(P<0.05)。相较于市政饮用水,采用灭菌水、纯化水和含消毒因子的水可降低DUWL微生物污染风险(P<0.05),超标组与未超标组定期消毒所用消毒剂分布无统计学差异(P>0.05)。结论 苏州市医疗机构口腔诊疗用水微生物污染严重,与诊疗量、水源类型及供水模式有关。Objective To investigate the microbial contamination of dental unit waterlines in Suzhou,and to analyze its influencing factors.Methods A questionnaire was designed.The basic information,the disinfection method and monitoring frequency of the waterlines in the stomatology department or dental clinic of the hospital were collected by on-site inquiry.The water samples were collected for colony counting and divided in to two groups according to exceeding the standard or not.The basic information of the medical institutions and the disinfection of the waterlines were compared.Results A total of 111 oral diagnosis and treatment institutions were surveyed,and 393 water samples were collected,of which 202 were qualified,with a pass rate of 51.40%.There was a significant difference in the total number of colonies in the handpiece output water of different medical institutions(P<0.05).There were statistically significant differences in the distribution of daily treatment volume,water source types and the proportion of DUWLs in each treatment unit between the medical institutions with and without exceeding the standard(P<0.05).Compared with municipal water,the use of sterilized water,purified water and water containing disinfection factor as oral treatment water could reduce the risk of DUWLs microbial contamination(P<0.05).There was no significant difference in the disinfectants used for regular disinfection between the exceedance group and the non-exceedance group(P>0.05).Conclusion The microbial contamination of oral water in medical institutions in Suzhou is serious.It is related to the amount of treatment,the type of water source and the mode of water supply.
