Educational Objectives

The overall objective of this article is to provide the reader with information on appropriate infection prevention protocols for environmental surfaces, waterlines and evacuation lines.

On completing this article, the reader will be able to do the following:

1.   List and describe the manner in which environmental surfaces may become contaminated and contribute to the chain of infection

2.   Review the methods by which housekeeping and  clinical contact surfaces can be cleaned and disinfected, as well as associated considerations

3.   List and describe the role of dental waterlines in cross-contamination and the transmission of microorganisms, and procedures that must be followed

4. Delineate the role of evacuation cleaners, their use and considerations in their selection


The treatment of environmental surfaces and dental unit waterlines (DUWs) is required for adequate infection prevention. Environmental surfaces include both clinical contact and housekeeping surfaces. Clinical contact surfaces must be treated with barrier protection or cleaned and disinfected for each and every patient, in accordance with guidelines, to prevent indirect transmission of microorganisms and disease. If barrier protection becomes compromised, the surface must then also be cleaned and disinfected. DUWs and evacuation lines must be treated on a daily basis. At the end of each day, evacuation lines must be flushed with a cleaner that will help reduce debris and microorganisms.
