  • Compositions and Methods for Preventing or Reducing Plaque and/or Gingivitis Using a Bioactive Glass Containing Dentefrice
    Publication number: 20070264291
    Abstract: Methods and compositions for the prevention and/or reduction of plaque, plaque build-up and/or gingivitis are provided. Bioactive glass compositions are provided which prevent or reduce plaque, plaque build-up and/or gingivitis through the use of low levels of small bioactive glass particles in amounts from about 0.25 to about 10% by weight in non-aqueous formulations. The resulting non-aqueous compositions are effective in dentifrice products and are stable and pass ISO (International Organization for Standardization) standards. Moreover, these bioactive glass containing non-aqueous compositions have unexpectedly high levels of antimicrobial activity against oral pathogens.
