Abstract
The present invention is directed to disinfecting compositions for dental unit water lines, particularly effective against microbial flora in biofilms which form on the luminal walls of the piping and reservoir components of dental equipment, as well as methods related to the use of such compositions to reduce microbial numbers in water-bearing dental and other equipment and maintain reduced levels on a continuous basis.
Claims17
A method of reducing or eliminating microbial flora associated with biofilm in a small diameter dental water line, said method comprising exposing said bioflim to a composition comprising an effective amount of chlorine dioxide within the concentration range of about 500 ppm to about 2500 ppm for a period of at least about 30 minutes to reduce or eliminate said microbial flora.
A method of reducing microbial flora associated with biofilm in a small diameter dental water line, said method comprising exposing said biofilm to a composition comprising an effective amount of chlorine dioxide within the concentration range of about 500 ppm to about 2500 ppm for a period of at least 30 about minutes to reduce or eliminate said microbial flora.
A method of reducing an initial population of microbial flora associated with biofilm in a small diameter dental water line and maintaining microbial flora within said biofilm at a reduced population in comparison to said initial population, said method comprising a first decontamination step and a second maintenance step;
- wherein said decontamination step comprises exposing said biofilm or said small diameter water line to a composition comprising an effective amount of chlorine dioxide within the concentration range of about 500 ppm to about 2500 ppm for a period of at least about 30 minutes to reduce or eliminate said microbial flora within said biofilm;
- and
- wherein said maintenance step comprises exposing said biofilm or said small diameter water line to a composition comprising a maintenance effective amount of chlorine dioxide or chlorine for a period of time and in a manner sufficient to maintain said microbial flora at about said reduced population.
