Abstract: The purpose of this study was to investigate contamination of the dental unit water systems in a sample of dental clinics in Saudi Arabia. Materials and Methods: A total of 270 water samples (200 mL/sample) was collected from the handpieces line, air-water spray and tap water sources of the dental clinics. Microorganisms were identified using established culturing techniques (Analytab Products Inc.). Results: The prevalence of bacterial contamination was 84% in dental unit water lines of handpieces and 64% in air-water spray, while it was 10% in tap water samples. Bacillus and Pseuodmonas were found to be the predominant (52%) pathogenic microorganisms. Conclusion: The results indicated that dental unit water systems tested were contaminated. Therefore, more efforts should be directed to reduce (if not totally eliminate) the number of pathogens in the dental unit water systems.
