| 摘 要： | 目的调查口腔专科综合治疗台水路污染的原因。方法分别采集综合治疗台不同时段牙钻手机喷水进行检测。结果使用牙钻手机治疗前，综合治疗台供水系统中自来水菌落数为（245．83±18．63）CFU／mL，明显高于蒸馏水菌落数（165．56±13．33）CFU／mL（f=11．66，P〈0．01）。使用牙钻手机为患者治疗后不及时空转30s，手机喷水菌落数分别高于使用牙钻手机治疗前和治疗后经空转手机30s后的喷水菌落数（均P〈0．01）；完成治疗后不及时空转牙钻手机并直接放置于操作台面过夜，手机喷水菌落数严重超标。结论加强对综合治疗台水路的清洗消毒管理，提高医生规范操作意识，可以减少口腔专科诊疗中医源性感染的危险性。

| Abstract: | Objective To investigate the causes of contamination of waterline of dental units in department of stomatology. Methods Water samples from outlet of handpieces of dental drills were taken during different period. Results Bacterial count of water from outlet of handpieces of dental drills was （245.83±18. 63）CFU/mL, which was obviously higher than that of distilled water （165.56±13.33）CFU/mL （t=11.66, P〈0.01）. Bacterial count of water after treating patients and without free-running handpieces was significantly higher than those before treating patients and free-running handpieces for 30s after treating patients respectively（ both P〈0.01） ; After treating patients, bacterial count of water from dental handpieces was seriously over standard when the handpieces didn＇t run and were put overnight on the dental units. Conclusion The cleaning and disinfection of waterline of dental units should be strengthened, and the consciousness of standard operation of dentists should be enhanced, so as to reduce the occurrence of nosocomial infection in dental patients. |
