目的评价Alpron消毒剂对牙科综合治疗台水管微生物污染的控制效果。方法采用三针注射器、高速手机、在使用Alpron溶液处理之前和之后，在22°C和37°C下评估了六个牙科综合治疗台的杯状填充器和手术洗手盆的微生物总活菌计数。结果研究发现，使用Alpron消毒剂溶液可以将牙科综合治疗台水管中的微生物数量减少到与饮用水相似的水平。在一个疗程后，所有单位的这种效果都维持了长达六周。在六个单位中的四个低微生物计数维持了13 weeks.Conclusions消毒剂可能有一个短期的作用，发挥控制微生物污染的牙科综合治疗台水管饮用水的质量。然而，从长远来看，必须注意重新设计牙科综合治疗台，以阻止微生物生物膜的建立。
Aims To assess the efficacy of a disinfectant, Alpron, for controlling microbial contamination within dental unit water lines.Methods The microbiological quality of water emerging from the triple syringe, high speed handpiece, cup filler and surgery hand wash basin from six dental units was assessed for microbiological total viable counts at 22°C and 37°C before and after treatment with Alpron solutions.Results The study found that the use of Alpron disinfectant solutions could reduce microbial counts in dental unit water lines to similar levels for drinking water. This effect was maintained in all units for up to six weeks following one course of treatment. In four out of six units the low microbial counts were maintained for 13 weeks.Conclusions Disinfectants may have a short term role to play in controlling microbial contamination of dental unit water lines to drinking water quality. However, in the longer term attention must be paid to redesigning dental units to discourage the build up of microbial biofilms.
