This course offers a comprehensive overview of the problem of dental unit waterline (DUWL) contamination. The Environmental Protection Agency regulates drinking water in the public water supply to ensure that the number of water organisms is kept at an acceptable level. The Centers for Disease Control and Prevention recommends that the water emitted from dental handpieces and air/water syringes be the same quality as drinking water.

This basic-level course discusses the complexity of DUWL contamination and the importance of monitoring contamination levels. The methods used to control microbial growth and the limitations associated with current approaches are also explained. Participants learn how to judiciously choose a DUWL disinfectant best suited to their practice needs.
