摘　　要：目的探讨工作状态下口腔科诊室的空气质量。方法使用空气消毒机连续30 d,每天对一面积为15 m2的口腔诊室进行2次消毒(早晨7∶00和下午13∶00,每次1 h),对工作过程中的诊室内空气连续采样(8∶00—17∶00,每小时1次,不包括13∶00),观察空气菌落数变化。结果上午8∶00的空气采样菌落数均值为(275.70±81.87)CFU/m3,9∶00—17∶00的空气采样菌落数均值为(411.80±175.66)～(968.10±204.14)CFU/m3。静态消毒后空气菌落数符合《消毒技术规范》要求,而持续1 h后空气中的菌落数明显超标(>500CFU/m3)。结论为保证口腔诊室空气质量在工作状态中符合国家规范要求,建议采用动态消毒措施并观察消毒效果。Objective To evaluate air quality of a dental clinic in the state of working. Methods Air of a dental clinic was disinfected by air disinfector twice a day for consecutive 30 days, disinfection was performed at 7 ： 00 AM and 13 ： 00 PM for 1 hour respectively, air samples in the state of working （once an hour between 8 ： 00AM-17 ： 00PM, 13 ： 00PM excluded） were collected, and bacterial colonies were counted. Results The average bacteria count were （275. 70＋81.87） CFU/m3 at 8 ： 00 AM, （411.80 ＋ 175. 66） CFU/m3-（968. 10 -＋ 204. 14） CFU/m3 at 9 ： 00 AM-17 ： 00 PM. Air quality was in line with the Technical Standard for Disinfection at static state after disinfection, bacterial colony significantly exceeded standard with the extension of working hours. Conclusion In or- der to ensure air quality of dental clinic in the state of working in line with national regulatory requirements, dynam- ic disinfection measures are recommended.
