HISTORY
Continuous pursuit of patient safety
The history of dental unit waterlines (DUWLs) is a testament to the evolution of infection control measures and the continuous pursuit of patient safety within the field of dentistry.
In the early days of dentistry, water for dental procedures was often sourced directly from local water supplies, a practice that did not meet the stringent standards required for medical and dental applications. However, the introduction of independent water reservoirs within dental chairs marked a pivotal advancement. These reservoirs stored and supplied water for dental procedures, reducing the risk of contamination from the local water supply.
In response to these concerns, infection control and patient safety took precedence. Regulatory bodies like the U.S. Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC), along with dental associations, developed guidelines and recommendations. These guidelines stressed the importance of regular flushing, monitoring, and maintenance practices to prevent bacterial colonization and biofilm formation within DUWLs. Technological advancements played a pivotal role in addressing these challenges. The introduction of anti-retraction valves, chemical treatments, filtration systems, and the use of separate water sources independent of the public water system all aimed to enhance dental water quality. These innovations were driven by the goal of ensuring that DUWLs consistently delivered water with bacterial counts below recommended levels.

Safety
Dental unit waterline safety stands as a pivotal element of infection control and patient care within the realm of dentistry. Ensuring the purity and reliability of the water used in dental procedures is of paramount importance, serving as a protective barrier for both patients and dental healthcare professionals against potential health hazards. Here, we delve into the fundamental facets of dental unit water line safety:
Regulatory Guidelines
Prominent regulatory bodies, including the U.S. Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC), in collaboration with dental associations, have established stringent guidelines and recommendations for upholding water quality within DUWLs. These guidelines underscore the critical significance of routine monitoring, systematic flushing, and diligent maintenance to thwart bacterial colonization and biofilm formation.
Infection Risk
While the colonization of microorganisms within DUWLs may not pose significant threats to healthy patients, individuals who are immunocompromised or particularly vulnerable may face an elevated risk of infection. The presence of waterborne pathogens, if unaddressed, could lead to adverse health consequences among susceptible patients.
Microbial Contamination
Dental unit water lines (DUWLs) have the potential to become breeding grounds for microorganisms, encompassing bacteria, fungi, and protozoa, over time. This contamination may arise due to factors such as the formation of biofilms within the waterlines, inconsistent water flow rates, and the possible retraction of oral fluids.
Dental unit water line safety assumes a pivotal role in the tapestry of infection control within dental practices.
By adhering to guidelines, implementing appropriate measures, and conducting regular monitoring and maintenance, dental practitioners can provide a safe and hygienic environment for dental procedures, safeguarding the well-being of patients and healthcare personnel.
What Products Are Available To Test, Clean, and Maintain Dental Unit Water Lines
Dental unit water line (DUWL) treatment products are integral to upholding water quality and safety within dental practice environments. These specialized products are engineered to control microbial growth, deter biofilm formation, and guarantee the integrity of water utilized during dental procedures.
Below, we categorize and discuss common types of DUWL treatment products, emphasizing their pivotal role in infection control:
Anti-Reversion Valves
- Anti-reversion valves are devices that prevent backflow or retraction of oral fluids into the DUWLs.
- These valves help reduce the risk of microbial contamination and biofilm formation.
- They are often integrated into dental unit designs for added protection.
Flushing
- Routine flushing of DUWLs is a fundamental practice to remove any stagnant water and debris.
- Flushing should be done at the beginning of the day, between patients, and at the end of the day to ensure fresh water circulation.
- Flushing times can vary but typically involve running water for at least 30 seconds to physically remove contaminants.
Filtration Systems
- Filtration systems are used to remove particulate matter and microorganisms from the water supply.
- These systems typically consist of filters designed to trap contaminants before they enter the DUWLs.
- Filtration systems can be effective in maintaining water quality.
Chemical Disinfectants
- Shock Tablets or Powders: Primarily employed for initial shock treatment, these products offer swift and effective elimination of microbial contamination. They incorporate disinfectant agents such as chlorine dioxide or silver ions.
- Liquid Chemicals: Liquid disinfectants, added to the dental unit's water reservoir or directly into DUWLs, serve to maintain water quality over time. Common options encompass hydrogen peroxide, iodine, and chlorine-based solutions.
Continuous Disinfection Systems
- Ultraviolet (UV) Light Systems: UV systems deploy ultraviolet light to disinfect water as it traverses the dental unit's waterlines, effectively eradicating bacteria and viruses
- Ozone Generators: Ozone generators produce ozone gas, a potent disinfectant that can be introduced into DUWLs to curtail microbial growth.
Self-Contained Water Reservoirs
- Some dental units are designed with self-contained water reservoirs that can be emptied and cleaned separately.
- Dental practitioners can clean and disinfect these reservoirs more effectively, reducing the risk of contamination.
Dental Unit Waterline Testing
- Testing Strips or Kits: Designed for routine monitoring, these kits empower dental professionals to gauge water quality within DUWLs. They provide insights into microbial contamination, endotoxin levels, and other impurities, enabling timely corrective actions.

RECENT NEWS
Dental unit waterlines continues to get a lot of scrutiny. It's not us at Dentistry’s Dirty Secret trying to scare the public. There have been a few major breaches with dental unit waterlines that you should know about.
Lawsuit: Dental Clinic used contaminated water during procedures, infected dozens of children
Eleven families are filing a lawsuit against a local dental office after their children contracted infections following routine procedures.
According to the lawsuit filed March 2 in Clayton County, Georgia, almost two dozen children between the ages of 6 and 10 contracted Mycobacterium abscessus infections after getting pulpotomies, or "baby root canals," at the Dentistry for Children of Georgia, LLC, formerly Dentistry for Children of Jonesboro.
What is the problem?
Mycobacterium abscessus, according to the CDC, is a bacterium distantly related to the ones that cause tuberculosis and leprosy and are sometimes found in water, soil, and dust.
The complaint claims a Mycobacterium abscessus "outbreak" occurred at the dental clinic's Jonesboro location between 2014 and 2016 and was a result of "severely contaminated water" used during irrigation and drilling.
