What are dental unit waterlines?
Dental Unit Waterlines are the tubing that carries water from the source to the dental unit which is connected to equipment, such as high and low-speed handpieces, air abrasion devices, air/water syringes, and ultrasonic scalers.
It’s important to note that dental unit waterlines are distinct from suction or evacuation lines. Evacuation lines are designed to remove fluids like saliva, irrigation water, particles, and debris from the oral cavity during a routine dental procedure. A good rule of thumb is any line that is connected to the dental unit and can also have water come out of it, is considered a dental unit waterline.
