Waterline maintenance does not need to be complicated, but it does need to be consistent. This article highlights proven solutions that help simplify dental unit waterline care, making it easier to stay on track with infection control and support safe patient treatment every day.
As a dental healthcare professional, you work year-round to keep your patients and colleagues safe and healthy. Maintaining strong infection control protocols is essential to that effort. When it comes to achieving a high level of safety in any practice, maintaining your dental unit waterlines (DUWLs) remains one of the highest priorities.
Dental waterlines play an important role in patient treatment, ensuring adequate irrigation of the oral cavity and cooling for powered equipment. However, the design of these systems also positions them as a potential source of infection. DUWLs feature long, narrow-diameter plastic tubing which, combined with inconsistent flow rates, periods of stagnation, and retraction of fluids from the oral cavity, creates optimal conditions for biofilm to develop and grow.
According to the Centers for Disease Control and Prevention (CDC), the moist inner surfaces of new lines can begin to accumulate colonies of bacteria and other microorganisms in just a few hours. If untreated, it can take less than a week for heterotrophic bacteria levels to reach 200,000 colony-forming units per mL (CFU/mL), far exceeding the Environmental Protection Agency (EPA) threshold for safe drinking water.
When contaminated lines are used during treatment, microbes can become dislodged and enter the water stream. As a result, patients may be exposed directly, while team members and others in the operatory may be exposed through aerosols and spatter. Past incidents have demonstrated the serious consequences of improper DUWL maintenance, reinforcing the importance of consistent protocols and reliable systems.
