Abstract: Objective To investigate the impacts of water supply on water quality in the pipeline of the dental comprehensive treatment platform to contribute to pollution control.Methods Totally 8 platforms from the stomatological department underwent 2-a detection and tracing.The water sources included tap water,distilled water and filtered water,and the discharge water went through sampling and bacteriological analysis before and after disinfection.Results The mean numbers of colonies by tap water,distilled water and filtered water were (472±385),(380±372) and (446±382) cfu/ml respectively,and the qualification rates by tap water,distilled water and filtered water were 33.3％,45.8％ and 37.5％ respectively.All the colonies numbers were limited within 0 and 60 cfu/ml with the qualification rate being 100％ after disinfection.Conclusion Water source cannot relieve bacterial infection effectively,and disinfection eliminates bacteria and improves water quality in the pipeline of the dental comprehensive treatment platform.
