ADA Guidelines for Infection Control

Tuesday, 21 January 2020

Most dental unit waterlines contain biofilm, which acts as a reservoir of microbial contamination. Biofilm in dental unit waterlines may be a source of known pathogens. Waterlines must be cleaned and disinfected in accordance with the manufacturer's instructions.

What does this mean for you?

In line with the Australian drinking water quality guidelines, water for tooth irrigation during cavity preparation and for ultrasonic scaling should be of no less than potable standard (Australian Drinking Water Guidelines 2011).

It is recommended that water from dental unit waterlines contain less than 200 colony forming units per mL. Bacterial levels can be tested through commercial microbiology laboratories.
