  • 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.

  • 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.

  • Patent number: 6017554
    Abstract: A stable solution cream, salve, or spray composition containing activated stabilized chlorine dioxide and phosphates, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for the prevention and treatment of abnormal conditions of the epithelium of bodily orifices. Examples of such abnormal conditions of the epithelium of the rectal, vaginal, urethral, oral, nasal, ocular, and auditory canal orifices include bacterial infections, such as Actinobacillus actinomycetemcomitans and Porphyromonoas gingivalis, and fungal infections, such as Candida, and leukoplakia. The preferred concentration ranges are between about 0.005%-2.0% chlorine dioxide, and between about 0.02%-3.0% phosphate. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.

  • Patent number: 5935592
    Abstract: A stable solution, cream, salve, or spray composition containing activated chlorine dioxide and phosphates, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for the treatment of vaginitis and endometriosis by reducing any of Candida, Actinobacillus actinomycetemcomitans, Pseudomonades, and Porphyromonas gingivalis present in the vagina or the uterus. The preferred concentration ranges are in the range of about 0.005% to about 2.0% of chlorine dioxide, and in the range of about 0.02% to about 3.0% of phosphate. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.4, at which pH chlorine dioxide becomes activated and releases sufficient chlorine dioxide to reduce motility and become lethal to the involved micro-organisms.

  • Patent number: 5902575
    Abstract: A stable solution, cream, salve, or spray composition containing chlorine dioxide and a phosphate, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for the prevention and treatment of abnormal conditions of the epithelium of bodily orifices. Examples of such abnormal conditions of the epithelium of the rectal, vaginal, urethral, oral, nasal, ocular, and auditory canal orifices brought about by any of leukoplakia, hairy leukoplakia, vaginitis, endometriosis, Candida Albicans, Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Pseudomonades, Candida species, and leukoplakia vulvae. The preferred concentration ranges are between about 0.005%-2.0% chlorine dioxide, and between about 0.02%-3.0% phosphate. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.

  • Patent number: 5834003
    Abstract: A method for oxidatively consuming volatile sulfur compounds selected from the group consisting of dimethylsulfide, hydrogen sulfide, and methylmercaptan at the epithelial barrier of the rectal, vaginal, urethral, oral, nasal, ocular, and auditory canal orifices to maintain the epithelial barrier and reduce penetration of any of Candida, Actinobacillus actinomycetumcomitans, Pseudomonades, and Porphyromonas gingivalis, said method comprising the step of applying to the orifices a composition comprising a topical preparation selected from the group consisting of liquid solutions, suspensions, semi-solids, salves, creams, and suppositories, wherein the topical preparation contains chlorine dioxide in a concentration in the range of about 0.005% to about 2.0% and a phosphate compound selected from the group consisting of disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodiuit phosphate, or sodium monofluorophosphate in a concentration in the range of about 0.02% to about 3.
