Patent number: 10285789Abstract: The addition of the Iodide ion by way of Potassium Iodide to a peroxide such as Hydrogen Peroxide in a basic medium yields Free Radical Oxygen and water; generating large amounts of heat and depleting the Hydrogen Peroxide in a matter of minutes. The Free Radical Oxygen generated in this reaction can be utilized to oxidize organic molecules that produce offending stains on select items, including teeth. Once the Free Radical Oxygen has oxidized the offending molecule the color is lost and the solubility changes allowing the colorless oxidized fragments of the offending molecule to be washed away in the solvent. The Iodide ion catalyzes the reaction allowing for precise control over the speed at which the stain is removed without the need for other expensive, cumbersome energy adding equipment such as lights, lasers, heat sources, etc.Type: GrantFiled: April 19, 2007Date of Patent: May 14, 2019Assignee: CAO Group, Inc.Inventors: Robert K. Larsen, Calvin D. Ostler

Patent number: 7530808Abstract: The present invention is a switch-closeable double barrel syringe and methods for bleaching teeth using it. The syringe comprises two separately contained barrels, each containing one component of a dental bleach, and a rotatable tip with orifices to match, when open, orifices in the barrels, and a mixing chamber. The tip rotates between open and closed positions in order to dispense bleaching compositions for use in dental hygene. Various formulations of bleaching compositions may be contained within the barrels, however the invention is ideally suited for those which require separate storage of active ingredients before use.Type: GrantFiled: September 20, 2004Date of Patent: May 12, 2009Assignee: CAO Group, IncInventors: Densen Cao, Calvin D. Ostler, Robert K. Larsen

Publication number: 20080311057Abstract: In toothpaste, the addition of the Iodide ion by way of iodide salts, such as sodium iodide and potassium iodide, to a peroxide such as hydrogen peroxide in a basic medium yields free radical oxygen and water; generating large amounts of heat and depleting the Hydrogen Peroxide in a matter of minutes. The free radical oxygen generated in this reaction can be utilized to oxidize organic molecules that produce offending stains on select items, including artificial teeth and other dental appliances. Once the free radical oxygen has oxidized the offending molecule the color is lost and the solubility changes allowing any loose fragments of the offending molecule to be washed away in the solvent. The iodide ion catalyzes the reaction allowing for precise control over the speed at which the stain is removed without the need for other expensive, cumbersome energy adding equipment such as lights, lasers, heat sources, etc.Type: ApplicationFiled: August 26, 2008Publication date: December 18, 2008Applicant: CAO GROUP, INC.Inventors: Robert K. Larsen, Calvin D. Ostler

Publication number: 20080311545Abstract: While various structures, compounds and methods Tooth whitening may be accelerated and intensified by use of ultrasonic energy. Although ultrasonic energy does nothing to directly enhance whitening (i.e., it has no direct effect on stains, tooth enamel, or peroxides), ultrasonic energy may be utilized to accelerate and intensify chemical reactions between a peroxide and another dental bleach constituent, consequently accelerating and enhancing the release of oxygen ions from the peroxide, which in turn accelerates and enhances the whitening of teeth.Type: ApplicationFiled: December 20, 2007Publication date: December 18, 2008Applicant: CAO GROUP, INC.Inventors: Calvin D. Ostler, Densen Cao, Lincoln Jolley

Patent number: 6116900Abstract: A dental bleach storage, mixing and delivery device and related method are disclosed. The device includes a barrel with at least two chambers. The chambers store components that when mixed can form a dental bleach or whitener. A plunger is provided that can be reciprocated within the barrel to force such components from their chambers. A mixing tip is provided for the end of the barrel. The components may be forced through the mixing tip which thoroughly mixes them together. The resulting bleach or whitener is applied to a patient's teeth where oxygen ions released from the bleach or whitener and will whiten the patient's teeth.Type: GrantFiled: November 12, 1998Date of Patent: September 12, 2000Assignee: LumaChem, Inc.Inventor: Calvin D.
