DUWL: A Topic of Discussion Since 1963

Course Description:

The topic of DUWL maintenance has re-surfaced regularly over the years. How far back does this topic go? Dr. G.C. Blake DDS published the very 1st report in 1963 on Bacterial Contamination. At the time, his study referenced ‘bacterial contamination’ as the term biofilm was non-existent. We now know the contributing factor of the DUWL maintenance issue is biofilm. The water itself is clean, however, it can be exposed to biofilm within the narrow tubing contaminating the water that comes in contact with clients. The maintenance program of a DUWL system can be simplified by equating the issue to risk management.

Course Objectives:
  • Review scientific literature concerning biofilms in dental unit waterlines
  • Apply a risk management approach for reducing health risks
  • Compare testing systems to differentiate between a CFU (Colony Forming Unit) test and a hygienic monitoring test
  • Understand the 3 step equation of clean, shock and test
  • Realize the maintenance of DUWL is NOT an event but rather an ongoing process
