摘　　要：目的了解重庆市各级医疗机构口腔科的诊疗用水卫生质量,为提高口腔用水质量提供理论依据。方法2022年6月至2023年6月,采用分层随机抽样方法,抽取重庆市35家医疗机构的口腔科开展诊疗用水的采样和细菌菌落总数的检测。参照我国《生活饮用水卫生标准》判断水样合格率,率的比较采用χ^(2)检验,以P<0.05为差异有统计学意义。结果共采集重庆市35家医疗机构口腔科的诊疗用水水样170份,合格水样133份,合格率为78.2%。超标的水样中,细菌菌落总数最高达到了100000 CFU/ml以上。除口腔科水源水的合格率为100%外,合格率最高的是漱口水,为82.3%;最低的是手机喷水,为66.7%;一级医院的口腔诊疗用水合格率为87.8%,二级医院为66.7%,三级医院为82.6%,合格率差异有统计学意义(χ^(2)=7.696,P=0.021);是否有过滤处理设备的水样合格率差异无统计学意义(χ^(2)=0.824,P=0.346)。结论重庆市各级医疗机构口腔科诊疗用水污染严重,建议尽快制定口腔用水相关的标准规范,提高口腔用水卫生质量。Objective To understand the hygienic quality of dental diagnosis and treatment water in medical institutions at all levels in Chongqing,and to provide theoretical basis for improving the quality of oral water.Methods From June 2022 to June 2023,a stratified random sampling method was used to select 35 medical institutions in Chongqing to conduct sampling of dental diagnosis and treatment water and detection of total bacterial colony count.The qualified rate of water samples was determined by referring to the National Standards for Drinking Water Quality.The comparison of rates was conducted byχ^(2)test,and P<0.05 was considered to be statistically significant Results A total of 170 water samples were collected from the dental department of 35 medica institutions in Chongqing,of which 133 were qualified,with a qualified rate of 78.2%.Among the water samples that exceeded the standards,the total number of bacterial colonies reached a maximum of over 100000 CFU/ml.In addition to the qualified rate of dental source water was 100%,the highest qualified rate was mouthwash(82.3%)and the lowest was dental handpiece water(66.7%).The qualified rates of water for dental diagnosis and treatment were 87.8%in first-level hospitals,66.7%in second-level hospitals and 82.6%in third-level hospitals,respectively,and the difference was statistically significant(χ^(2)=7.696,P=0.021).There was no statistically significant difference in the qualified rate of water samples with or without filtration treatment equipment(χ^(2)=0.824,P=0.346).Conclusions The pollution of dental diagnosis and treatment water in medical institutions at all levels in Chongqing was serious.It is suggested that the relevant standards and specifications of dental water should be formulated as soon as possible to improve the hygiene quality of dental water.
