Microbial Biofilm: Contamination in Dental Chair Unit.

This short review focuses on biofilms in the dental clinic environment. Microbial biofilms are potentially a significant source of contamination and cross-infection in the dental clinic. Biofilms in dental chair unit waterlines (DUWLs), suction hoses and fittings pose the most significant risk as these may come into contact with the patient during treatment. These can be managed effectively by regular disinfection using chemical and other methods to minimize reservoirs and disseminators of potentially pathogenic bacteria from these areas.
