Why should you flush water through dental unit waterlines between patients?

Question

Quizplus · Accepted Answer

Flushing water through dental unit waterlines between patients is important to temporarily lower the number of microbes in the water, which helps reduce the risk of cross-contamination between patients. While biofilm removal and lubrication of the high-speed handpiece are important aspects of dental unit maintenance, they are not the primary reasons for flushing water between patients. Sterilizing the inside of the air-water syringe handle is also an important practice, but it should be done separately and not necessarily as part of the routine flushing process.
