Dental evacuation lines and dental unit waterlines (DUWL) are two distinct systems in a dental office that serve different purposes, though they are often mixed up. It’s important to know your lines, because there are specifically designed products to clean and maintain each of them. With proper maintenance, you can ensure that your practice is getting the most out of your valuable equipment.

Dental evacuation lines are used to remove fluids and debris from the patient’s mouth during dental procedures. These lines are connected to the dental chair and suction units, and they help keep the patient’s mouth clean and dry during treatment. Dental evacuation lines can become contaminated with saliva, blood, and other fluids, and they require regular cleaning and maintenance to prevent buildup.

DUWLs, on the other hand, are used to supply water to dental instruments, such as handpieces and air-water syringes. The water that flows through these lines can also be used to cool dental instruments and irrigate the patient’s mouth during treatment. However, DUWLs can also become contaminated with bacteria and biofilm, which can lead to potential health risks for patients. Therefore, DUWLs require regular flushing and disinfection to ensure that the water used in dental procedures is safe and free of harmful microorganisms.
