Disinfection and monitoring of dental unit waterlines.
Recent increased awareness of dental unit waterline contamination has prompted investigations into potential protocols for improvement in the quality of water delivered to patients. When the protocol was followed (n = 12), contamination levels were reduced to below measurable colony forming units (CFU) defined as < 1 CFU/mL within three weeks and maintained thereafter. When adherence to the protocol was not strictly followed after initial disinfection, contamination quickly returned and remained until additional disinfection was performed.
