  • Publication number: 20220323318
    Abstract: A human oral care composition, includes safe and effective amounts of the fluoride ion and stabilized chlorine dioxide, that may take the form of a paste, gel, rinse, spray, powder, varnish or similar that reduces demineralization and promotes remineralization of teeth. The method includes the topical application of the composition to the human oral cavity (including but not limited to the teeth, gingiva, and tongue), preferably at least once daily, to enhance the anti-caries effect of fluoride by released chlorine dioxide compromising any biofilm present.

  • Publication number: 20220280402
    Abstract: Various embodiments described herein provide for a multi-component compositions and methods for its pharmaceutical and cosmetic use, comprising a combination of an aliphatic anionic compound, an oxidative compound, and a buffering system. Source of fluoride ion and other carriers are optional ingredients. The aliphatic anionic compound and the oxidative compound function together, in presence or absence of fluoride ion source, to protect the oxidative compounds from degradation prior to use and upon use, and to enhance the efficacy of the composition. In addition to achieving greater stability, combined effects of the aliphatic anionic compound, oxidative compound and source of fluoride ion achieve enhanced fluoride uptake, higher enamel protection by enhanced remineralization and reduced demineralization, increased plaque removal, reduced re-growth of plaque polymicrobial biofilm, greater amount of chlorite ion availability and effective oxidation of salivary biomolecules.

  • Patent number: 11433010
    Abstract: Described herein are single-phase compositions and methods for its pharmaceutical and cosmetic use, comprising (i) a combination of N-acyl sarcosinate, (ii) an oxidative compound, and (iii) a buffering system in amounts and embodiments effective to protect the oxidative compounds from degradation prior to use and upon use and to enhance the efficacy of the composition in removing polymicrobial biofilms, reducing the re-growth of polymicrobial biofilms that leads to plaque formation, greater availability of chlorite ion for antimicrobial and cosmetic purposes, and effective oxidation of salivary biomolecules. When these single-phase compositions are comprised of a source of fluoride ion, they also achieve enhanced enamel fluoride uptake, higher enamel protection by enhanced remineralization and reduced demineralization of teeth when compared to US Pharmacopoeia Reference Dentifrice, prior known toothpastes comprising stabilized chlorine dioxide and comparable commercial dentifrices.

  • Patent number: 11000710
    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, wherein the activation and release of chlorine dioxide from the composition a) occurs rapidly and without a period of induction, b) results from the oxidative reduction and consumption of amino acids and volatile sulfur compound precursors, and c) generates twice the available chlorine dioxide gas as that generated from simply lowering the pH of the composition. The preferred concentrations of stabilized chlorine dioxide in this invention are in the range of 0.005% to 2.0% (w/v) wherein the pH of the composition is initially lowered by a citrate and then stabilized by a peroxy compound.

  • Patent number: 7875460
    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.
