Evacuation Lines, Environmental Surfaces, and Dental Unit Waterlines
Presented by: Dental Learning Credits: 2 CE

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.

Introduction

   Impression material selection depends on the procedure at hand and the clinician’s preference. Alginate, an aqueous hydrocolloid, was developed during the 1940s. Recently, ‘alginate substitutes’ have been introduced as an alternative to alginate materials.

Tips for a Healthy Holiday Season

Tips for a Healthy Holiday Season

As the festive season approaches, it is helpful to remember good practices for infection prevention at home. Sharing utensils and glasses helps to transmit microorganisms and fosters the spread of disease, while sharing tasty plates of dessert among family and friends with different utensils still results in contamination – unless everyone only has one bite! Using separate utensils and not sharing glasses or plates (or sippy cups with young children) helps prevent the transmission of microorganisms, oral disease and other infections. Have a happy and healthy festive season.

Defeating Oral Micro-organisms

Defeating Oral Micro-organisms

Oral micro-organisms have been implicated in oral and systemic infections in the same patient. They have also been implicated in cross-infections from a patient to other patients and healthcare workers.  In the dental office, bacterial aerosols are generated that then expose staff and patients to micro-organisms.  The greatest treatment-related source of bacterial aerosols is the use of ultrasonic scalers, followed by the use of high-speed handpieces. The bacteria in the aerosols are due to bacterial loads present in saliva and on oral tissues.
