目的：了解综合性医院口腔科综合治疗台水路（DUWL）污染状况，为采取相应预防措施提供科学依据。方法选取3所综合医院，A 医院以自来水作为直接水源，B 医院以蓄水池水作为水源，C 医院以反渗透水过滤系统过滤水作为水源，每季度对医院综合治疗椅的手机喷水和冲洗水进行水样采集，检测水样细菌菌落总数。结果 A 医院水源水合格率为75．00％（3／4）；DUWL 手机喷水和冲洗水合格率均为0（0／40），菌落数分别为（1．20×103～5．53×104）CFU／mL（M＝3．80×104 CFU／mL）、（2．11×104～1．66×105）CFU／mL（M＝4．80×104 CFU／mL）。B 医院水源水、手机喷水和冲洗水合格率分别为50．00％（2／4）、60．00％（24／40）和72．50％（29／40），手机喷水和冲洗水菌落数分别为（0．00～3．71×106）CFU／mL（M＝83．00 CFU／mL）、（0．00～2．39×106）CFU／mL （M＝72．00 CFU／mL）。C 医院水源水合格率100．00％（4／4）；手机喷水和冲洗水合格率分别为55．00％（22／40）和65．00％（26／40），菌落数分别为（0．00～6．20×103）CFU／mL（M＝96．00 CFU／mL）、（0．00～1．63×103）CFU／mL（M＝87．50 CFU／mL）。结论综合医院口腔科 DUWL 细菌污染严重，应加强对水源水的过滤消毒和 DUWL 的日常消毒与规范化管理。

Objective To realize the contamination status of dental unit waterlines (DUWL)in general hospitals, and provide scientific evidence for making preventive measures.Methods Three hospitals were selected for study, water source adopted by hospital A,B and C was running water,reservoir water,and filtered water through reverse osmosis filtration system respectively,specimens of dental handpiece spray water and flushing water of dental chair units were collected quarterly,total bacterial colony in water were detected.Results The qualified rate of source wa-ter,handpiece spray water,and flushing water in hospital A was 75.00%(3/4),0 (0/40)and 0 (0/40)respectively,col-ony count of handpiece spray water and flushing water was (1.20×103 -5.53×104 )CFU/mL(M=3.80×104 CFU/mL) and (2.11×104 -1.66×105 )CFU/mL(M=4.80×104 CFU/mL)respectively.The qualified rate of source water,hand-piece spray water,and flushing water in hospital B was 50.00%(2/4),60.00%(24/40)and 72.50%(29/40)respectively, colony count of handpiece spray water and flushing water was (0.00 -3.71 ×106 )CFU/mL(M=83.00 CFU/mL)and (0.00-2.39×106 )CFU/mL(M=72.00 CFU/mL)respectively.The qualified rate of source water,handpiece spray wa-ter,and flushing water in hospital C was 100.00%(4/4),55.00%(22/40)and 65.00%(26/40)respectively,colony count of handpiece spray water and flushing water was (0.00-6.20×103 )CFU/mL(M=96.00 CFU/mL)and(0.00-1.63×103 )CFU/mL(M=87.50 CFU/mL)respectively.Conclusion Water of DUWL in general hospitals is seriously con-taminated,disinfection and standardized management of source water and DUWL must be strengthened.
