  • Patent number: 10112831
    Abstract: A method of producing chlorine dioxide involves generating chlorine dioxide gas by deforming a container body of a chlorine dioxide generator which is deformable in response to application of a force to the container body from outside of the container body. The deforming of the container body causes an enclosure contained in the cylinder body to be broken to bring an aqueous chlorite solution into contact with a solid acidic composition to generate chlorine dioxide gas that is discharged via a gas discharge port of the container body to outside of the container body. The method additionally involves submerging in water at least the gas discharge port of the container body during the generation of the chlorine dioxide gas to dissolve the chlorine dioxide gas discharged via the gas discharge port in the water.

  • Patent number: 9827174
    Abstract: A formulation starts as a gel and transforms into a foam under influence of light and heat to expand out into the oral cavity of a user for advantageous health benefits. A closed system mouthpiece includes light and heat generation to activate the formulation to increase its volume. Application of heat above a threshold temperature causes the gel to transform into foam and expand out of the mouthpiece and into the oral cavity. With the foam so dispersed within the oral cavity, activation of a light source embedded within the mouthpiece enhances the bacteria killing properties of the now foam material. The foam spreads onto the tongue of the user as well and acts to kill any damaging bacteria found there. As a result, the pH balance of the mouth is restored to a neutral level in the range of 6.75 to 7.25 or maintained at that pH level.

  • Patent number: 9642780
    Abstract: The present invention relates to a kit of parts for detection and removal of carious dentin tissue comprising: (i) one or more compounds being a hydrazine derivative, and (ii) means for chemical treatment of carious dentin tissue. Further, the invention concerns a preparation containing an active, caries-dissolving two-component liquid in the form of a first active, caries-dissolving component and a second component which reduces the aggressiveness of the active component to mucous membranes, a viscosity increasing substance and one or more compounds being a hydrazine derivative. The hydrazine derivative labels carious dentin tissue selectively and substantially irreversibly in the presence of healthy dentin tissue, which is useful in the context of caries removal.

  • Patent number: 9408788
    Abstract: The present invention relates to a multicomponent oral health care composition, comprising a source of a fluoride ion, a source of a calcium ion, a source of a phosphate ion, and stabilized chlorine dioxide, that can be used as a toothpaste, oral spray or a mouth wash/oral rinse formulation. The different components in the composition act synergistically together to clean the teeth and mucous membranes of an oral cavity of a subject, perfuming them or protecting them in order to keep them in good condition, change their appearance or correct unpleasant odors. They achieve this by inhibiting caries, promoting teeth remineralization, and helping to alleviate dentine hypersensitivity, gingivitis and periodontal disease.

  • Patent number: 9393184
    Abstract: An antimicrobial oxychlorine oral rinse composition for preventing and treating oral malodor and diseases, tooth decay with improved palatability and tissue compatibility, includes an aqueous chlorine dioxide and chlorite ion solution with the chlorite ion predominating in the multiple oxychlorine rinse composition. A method for preparing such antimicrobial oxychlorine oral rinse composition comprising 3 ppm to about 200 ppm of chlorine dioxide, by first preparing an aqueous solution with about 7 to 400 ppm of chlorite ion; then an aqueous acidifying agent concentrate which, upon introduction to the chlorite solution, reduces its pH to about 4.5 to 6.0; then a second aqueous buffer-producing oxidant combination concentrate. The first acidifying agent concentrate is added to the chlorite ion solution and the second aqueous buffer-producing oxidant combination concentrate is added to the acidified chlorite ion solution, producing an antimicrobial oxychlorine oral rinse composition at about 5.0 to 6.8 pH.
