US Patent:

7530808, May 12, 2009

Filed:

Sep 20, 2004

Appl. No.:

10/945550

Inventors:

Densen Cao - Sandy UT, US
Calvin D. Ostler - Riverton UT, US
Robert K. Larsen - Sandy UT, US

Assignee:

CAO Group, Inc - West Jordan UT

International Classification:

A61C 5/04
B67D 5/60

US Classification:

433 89, 2221455

Abstract:

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.

Appl. No.:

10/797628

Inventors:

Robert Larsen - Sandy UT, US
Calvin Ostler - Riverton UT, US

International Classification:

A61C005/04

US Classification:

433/089000

Abstract:

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.

Inventors:

Robert Larsen - Sandy UT, US

International Classification:

A61K 8/22
A61K 8/44

US Classification:

424053000

Abstract:

Structures and methods for delivering topical compositions are disclosed that fully integrate the topical composition with a carrier. One example adds a liquid topical composition, such as a dental bleach, to a liquid polymer carrier, mixes the two, and then solidifies the mixture. The solidified mixture is a delivery device which is then contacted with the human body in order for the topical composition have its desired effect on the body. Another example embeds the topical composition in an absorbent material. When the absorbent material is contacted with a portion of the human body, the topical composition can have its desired effect.
