【摘要】：目的研究牙科综合治疗台水系统细菌污染状况及消毒效果。方法通过现场采样和细菌定量检测方法,对江苏省部分综合医院口腔科和口腔专科医院口腔科综合治疗台水路细菌污染情况及消毒效果进行了检测。结果共采集口腔综合治疗台水路水样677份,包括水源水、牙钻手机出口水、喷枪出口水和漱口水,细菌含量范围为0~105cfu/ml。经有效氯10 mg/L消毒处理后治疗台水路水质合格率为79.17%;用浓度20 g/L过氧化氢消毒处理后治疗台水路水质合格率为88.89%。安装过滤器可有效降低治疗台水路污染,牙钻手机和喷枪采取预排水0.5 min,即可使细菌污染明显降低。结论口腔医疗机构综合治疗台水系统细菌污染严重,通过更换过滤器、预排水和化学消毒剂消毒等方法进行消毒干预。
[Abstract]:Objective to study the bacterial contamination and disinfection effect of dental comprehensive treatment water system. The bacterial contamination and disinfection effect of the comprehensive treatment platform in the stomatology department and the stomatology department of some general hospitals in Jiangsu Province were tested. Results 677 water samples were collected, including the source water. Dental drill mobile phone outlet water, spray gun outlet water and mouthwash, The bacterial content was in the range of 0 ~ 105cFu / ml. The qualified rate of water quality was 79.17 after disinfection with 10 mg/L of available chlorine, and 88.89% after disinfection with 20 g / L hydrogen peroxide. Installation of filter can effectively reduce water pollution. If dental drill cell phone and spray gun are used for 0.5 min, the bacterial contamination can be reduced obviously. Conclusion the bacterial contamination in the water system of the comprehensive treatment table of dental medical institution is serious, and the filter is replaced. Pre-drainage and chemical disinfectant disinfection and other methods to carry out disinfection intervention.
