Package Description

Dental Unit Waterlines (DUWLs) are in the news and on inspection checklists. But the process of testing and treating waterlines is often misunderstood or even forgotten about. Science shows us that many of the aerosols we are producing in our operatories come directly from the biofilm growth in our DUWLs. And just like the biofilm in the mouth, it can be stubborn to remove. How can you keep you and your patients safe? In this dynamic presentation, attendees will learn the why, how, and the what of dental unit waterline compliance. From testing to daily maintenance, this course will turn you into a Waterline Warrior and motivate you to go back to the op and Crash the Biofilm Party!

Learning Objectives:

  1. Describe the importance of clean dental unit waterlines
  2. Define the steps needed to “pass the test”--shock, test, treat, maintain
  3. Discuss products on the market that can make your job easier
