摘　　要：目的观察3种不同消毒方式对口腔综合治疗台水路(DUWL)污染的持续控制效果。方法采用现场采样和细菌定量检测方法,对3种消毒方法持续控制DUWL污染的效果进行观察。结果用有效氯500 mg/L含氯消毒剂每周处理1次和有效氯20 mg/L含氯消毒剂每日处理1次,可使三用枪水和高速手机水细菌总数连续24周保持<100 cfu/mL。用有效碘6 mg/L聚碘树脂置于水路中持续作用,可使三用枪水1~24周和高速手机水4~24周保持细菌总数<100 cfu/mL。结论3种消毒方法均能使DUWL水质达到饮用水标准,聚碘树脂更具有优越性。Objective To observe the effect of three different disinfection methods on sustained contamination control of dental unit waterlines(DUWL).Methods Site sampling and quantitative bacterial detection were used to observe the effect of three disinfection methods on sustained contamination control of DUWL.Results Using chlorine-containing disinfectant with 500 mg/L of available chlorine once a week or with 20 mg/L of available chlorine once a day,it could maintain a total bacterial count of less than 100 cfu/mL in water from triple syringes and high-speed handpieces for 24 consecutive weeks.Using iodinated resin with 6 mg/L of available iodine for continuous exposure,it could maintain a total bacterial count of less than 100 cfu/mL for 1 to 24 weeks in water from triple syringes and 4 to 24 weeks in water from high-speed handpieces.Conclusion All three disinfection methods can make the water quality of DUWL meet the drinking water standard,and iodinated resin has more superiority.
