Abstract:
Water samples were collected from dental handpiece and air-water syringe lines at various times during the day and cultured for the presence and prevalence of various microbes. It was found that the longer a dental unit was out of use, the greater the microbial build-up in water lines. However, purging lines for two to three minutes at the start of the day and between patients significantly reduced microbial presence.
