  • Patent number: 9682023
    Abstract: A method for preventing oral diseases caused by dental biofilm and plaque accumulation, such as gingivitis and periodontitis by application of a single-phase stabilized chlorine dioxide composition at a concentration range of about 0.005% to about 0.800% (w/v) at a pH in the range of 6.0 to 7.4. The bactericidal properties of stabilized chlorine dioxide include reduction (kill) of anaerobic/aerobic/facultative gram-negative and gram-positive oral bacteria occurring in plaque or polymicrobial biofilms. The composition may be in the form of wash, rinse, soak, paste, gel, aerosol spray, or other suitable delivery system.
    Type: Grant
    Filed: January 5, 2015
    Date of Patent: June 20, 2017

  • Patent number: 8926951
    Abstract: A composition and method of stabilized chlorine dioxide at a concentration range of about 0.005% to about 0.800% (w/v) at a pH in the range of 6.0 to 7.4 for the prevention of oral diseases caused by dental biofilm and plaque accumulation, such as gingivitis and periodontitis, through bactericidal properties is disclosed. The bactericidal properties of stabilized chlorine dioxide are further expanded to include reduction (kill) of anaerobic/aerobic/facultative gram-negative and gram-positive oral bacteria occurring in plaque or polymicrobial biofilms. The composition may be in the form of wash, rinse, soak, paste, gel, aerosol spray, or other suitable delivery system.

  • Publication number: 20090016973
    Abstract: The discovery of use of stabilized chlorine dioxide at a concentration range of about 0.5% to about 0.9% (w/v) as a composition for the prevention of oral disease through bactericidal and bacteriostatic properties within a microbial environment is disclosed. The bactericidal properties of stabilized chlorine dioxide are further expanded to include kill of an increased number of anaerobic/aerobic/facultative gram-negative and gram-positive oral bacteria occurring in mixed microbial communities. The further discovery of the bacteriostatic properties of stabilized chlorine dioxide present within a microbial environment which inhibit the re-growth rate of oral bacteria after exposure resulting in significant reduction of plaque and oral malodor production is disclosed. The stabilized chlorine dioxide may be in the form of an oral wash or rinse in solution.
