  • Publication number: 20100233101
    Abstract: The composition and method for the use of stabilized chlorine dioxide as an antimicrobial agent against oral microorganisms for the treatment and prevention of halitosis and prevention of oral diseases through its oxidative consumption and inactivation of volatile sulfur compounds and their amino acid precursors is disclosed. Preferred concentrations of stabilized chlorine dioxide in this invention are in the range of 0.005% to 2.0% (w/v).

  • Publication number: 20100221198
    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: 20100074970
    Abstract: A method and composition for preventing and treating all forms of osteonecrosis of the jaw are disclosed. The composition is comprised of 0.005%-2.0% weight/volume (w/v) chlorine dioxide source, such as sodium chlorite, chlorite ion, stabilized chlorine dioxide or similar and may take the form of a paste, gel, rinse, spray, powder, varnish or similar. The method for treatment and prevention includes the application of the composition in the oral cavity and other body areas affected by osteonecrosis of the jaw.

  • Publication number: 20100009009
    Abstract: A composition of stabilized chlorine dioxide at a concentration range of about 0.0004% to about 0.8% (w/v) having anti fungal properties to prevent oral fungal infections and method of use are disclosed.

  • 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.

  • Publication number: 20090017548
    Abstract: A method for determining the available treatment dosage of stabilized chlorine dioxide in the prevention and the treatment of plaque accumulation, volatile sulfur compound production, gingivitis and periodontitis, and for differentiating the treatment dosage from other chlorine-containing compounds that may not have such beneficial effects is disclosed. When in solution as stabilized chlorine dioxide, the presence of other ions such as chlorate and chloride may not only obscure results as to the concentration of stabilized ClO2, but also reduce the predicted effectiveness. The present invention uses validated analytical methods to predict the effectiveness of stabilized ClO2 by more precisely measuring its concentration in solution. Such measurement renders precision at a level required of food-grade and pharmacy-grade chemotherapeutic agents in the oral cavity. Preferred concentrations are within the range of about 0.005 to about 2% (w/v) stabilized chlorine dioxide.
