Reducing contamination in your DUWLs
March 21, 2012
The purpose of this study was to evaluate the efficacy of Citrisil tablets in controlling microbial contamination, preventing biofilm formation and enhancing biofilm removal from dental unit waterlines. Test materials included Citrisil™, Citrisil Shock™, Aseptisil™ liquid and Aseptisil™ powder. Sterilex-powder served as control during the shock treatment. Pseudomonas aeruginosa and Klebsiella pneumoniae were used to inoculate regular polyurethane dental tubing. Experiments were conducted using a dental unit waterline biocide test apparatus and methodology in the ANSI/ADA’s draft standard.
