Dental unit waterlines (DUWLs) home a flourishing community of bacteria and protozoa. These microbial inhabitants originating from the local water supply strongly hold to the inner walls of the tubing by building a biofilm. Even though the majority of the bacteria and protozoa do not pose a risk to most patients, some opportunistic pathogens can proliferate in the protection of the biofilm. When we consider that up to a million bacteria can be released in only one millilitre of water pouring out a dental handpiece, we may contemplate the need to solve the problem.
- Course will address the question of the actual infectious risk associated with DUWLs through a quick review of the literature and presentation of the research result of the lecturer.
- Participants will then learn what are the strategies to reduce the risks and lower microbial counts in their dental units.
