Abstract:
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.
