Abstract

Introduction: The water used in dental procedures may be contaminated and source of infection for patients and dental staff. Objective: The aim of this study was to compare the effectiveness chlorhexidine 0.1% and sodium hypochlorite 1% in the disinfection of dental unit waterline. Method: Three dental units were disinfection with chlorhexidine and three with sodium hypochlorite by flushing the triple syringe for two minutes. Water samples collected before and after disinfection and in the end of the day were analyzed microbiologically. Samples of the supply filter were also analyzed. Results: Samples collected before disinfection showed high levels of contamination (> 500 CFU / ml). After use of disinfectants, the samples were within the recommended standards by the American Dental Association – ADA (< 200 CFU / ml). The water supply filter was also within the limits established by the ADA. Conclusion: Chlorhexidine 0.1% was effective as sodium hypochlorite 1 % for the disinfection of dental unit waterlines.
