3 Safer Water Hygiene Better Infection Control The goal of infection control in any specialty practice is to minimize the risk from exposure to potential pathogens and create safe working environment to treat patient. In routine dental practice, proper infection control ensures that your dental facilities are safe places to deliver quality dental care. Infection control in dental offices includes safe dental unit water and waterlines, which however are often areas being overlooked. Prevention of biofilm formation in dental unit waterlines must be given considerable importance as the quality of dental unit water is critical to effective infection control. Microorganisms colonize in biofilms within waterlines and contaminate dental treatment waters in dental units. Clinicians and patients are exposed to water from these units, as well as aerosols produced by dental instruments. To minimize this potential source of cross contamination, clinicians must implement appropriate strategies for cleaning, disinfection and maintenance. Waterlines should be aseptically maintained with the same detail as the other environmental surfaces in the operatory. Regulatory Guidelines & Standards Recommendations for DUWL water quality: American Dental Association (ADA): < 200 CFU/ml of heterotrophic water bacteria Centers for Disease Control (CDC): < 500 CFU/ml of heterotrophic water bacteria (EPA regulatory standards for drinking water) The general international agreement is that water quality of dental unit systems should meet the demands for drinking water. International regulatory standards for drinking water: Japan: < 100 CFU/ml Europe: < 200 CFU/ml USA/Australia: < 500 CFU/ml In 1993, the CDC recommended that dental unit waterlines be flushed at the beginning of each clinic day to reduce the microbial load. However, Biowell has found that this practice does not affect biofilm in the waterlines or improve the quality of water used during dental treatment. Even the rather liberal recommended value of < 500 CFU/mL cannot be achieved using this method. Dental unit water that remains untreated will never meet drinking water standards. 2

4 Issues for Dental Water & Waterlines Ineffective disinfection practices Lack of continuous disinfection treatment Biofilm formation, tube clogging and water re-contamination Elevated risks of cross-contamination during disinfection intervals Contamination in dental unit water lines results from the formation of biofilm, a sticky, slimy layer of bacterial colonies. These colonies form from the bacteria that live in water supplies, and they attach on the sides of pipes and other containers, grow and colonize, leading to elevated bacterial counts in dental units and thus an increased risk for the patient and the dentist. Chlorine in tap water is removed by filters, exposing the water to contamination risks. Traditional chemical treatment by man reveals periodical risks and concerns of chemical residue and metal corrosion in the dental units. UV disinfection will only work for the covered segment. UV The mist from water being sprayed into a mouth is aerosolized, where it is then inhaled by both the patient and the dental professionals! The water that contains high levels of bacteria comes in direct contact with wounds during treatment! Without residual disinfection, biofilm starts forming within pipes. Water passes through dental unit water lines that already contain biofilm, the water will become contaminated. Chemical Dental unit tubing is very narrow, causing more bacteria to be sloughed off and carried out since the water has maximum contact with the sides of the very narrow tubing. Untreated dental unit water can contain in excess of 100,000 cfu/ml of bacteria. Conventional Solutions & Concerns Filter & UV Filtration and UV radiation are only effective against free bacteria in water. They have no long-term effect on bacteria that remains in biofilm and the microbial populations in the water system. Chemicals Despite the fact that the use of chemicals reveals operational handling and residual risks, they are applied periodically meaning that the water and waterlines are always under risks during treatment intervals. 3
