Learning Objective: 

• Identify the risks of biofilm and microbial contamination in untreated waterlines.  
• Explain safety guidelines related to dental waterline testing and maintenance.  
• Test water quality using nano gold particle technology.  
• Develop a protocol for when and how to test waterlines to maintain compliance and safety.

Dental unit waterlines are a hidden but critical aspect of infection prevention. Left unmonitored, they can harbor dangerous levels of biofilm and microbial contamination, putting both patients and providers at risk. This hands-on course will explore the why and when of waterline testing, drawing from the CDC Guidelines for Infection Control in Dental Health-Care Settings and dental safety recommendations. Participants will gain practical hands-on experience using nano gold particle technology, a modern innovation that provides a gold standard for waterline testing. Attendees will learn how to interpret results and build confidence in creating and maintaining a reliable testing protocol. Through step-by-step instruction and guided practice, participants will leave with a deeper understanding of the risks of contamination, the importance of routine monitoring, and the tools needed to ensure compliance, protect patients, and foster trust in dental safety standards. Whether you’re a clinician, educator, or infection control coordinator, this course will provide the science, the guidelines, and the hands-on skills needed to keep your waterlines safe.
