Which device has been associated with dental water-line biofilm?

The device that has been associated with dental water-line biofilm is the ultrasonic scaler. Ultrasonic scalers utilize water to cool and flush debris during the scaling process. The water that is used can become contaminated with bacteria, leading to the development of biofilm within the water lines of the dental unit. Biofilm is a complex aggregation of microorganisms that adhere to surfaces, and it can thrive in the moist environment provided by dental water lines if not properly managed.

Regular maintenance and disinfection of dental water lines are crucial to prevent biofilm formation and to ensure that the water used during procedures is safe for patient use. This connection highlights the importance of proper infection control protocols in maintaining a hygienic dental practice and protecting both patients and dental professionals.
