Ensuring Safe Dental Unit Waterlines
Biofilms are a collection of microorganisms firmly attached to a moist surface by a slimy matrix that can survive in a variety of environments. Biofilms are found in nature, industry, and healthcare settings — including dental unit waterlines (DUWLs). Two forms of bacteria are related to biofilm formation: planktonic (single free-floating) and attached communities (groups or clusters). Initially, planktonic bacterial cell walls adhere to surfaces using a polymer (glycocalyx). More bacteria begin to proliferate and colonize, giving the complex microbial colony a protective slimy layer (Figure 1).
