Dental chair units (DCUs) use water to cool and irrigate DCU-supplied instruments and tooth surfaces, and
provide rinsewater during dental treatment. A complex network of interconnected plastic dental unit waterlines
(DUWLs) supply water to these instruments. DUWLs are universally prone to microbial biofilm contamination
seeded predominantly from microorganisms in supply water. Consequently, DUWL output water invariably
becomes contaminated by high densities of microorganisms, principally Gram-negative environmental bacteria
including Pseudomonas aeruginosa and Legionella species, but sometimes contain human-derived pathogens
such as Staphylococcus aureus.
Patients and staff are exposed to microorganisms from DUWL output water and to contaminated aerosols
generated by DCU instruments. A wide variety of approaches, many unsuccessful, have been proposed to
control DUWL biofilm. More recently, advances in biofilm science, chemical DUWL biofilm treatment agents
such as HOCl, DCU design, and supply water treatment with HOCl have provided effective long-term solutions
to DUWL biofilm control.
– Removes and prevents future bio-film buildup in DUWL systems.
– Kills 99.99% of pathogens present in water line.
– No risk of cyto-toxicity.
– Significantly reduces the risk of human infection
