Abstract:
The invention encompasses combinations of bioactive glass composition and potassium salts that are useful in conjunction with delivery agent such as, for example, toothpastes, mouthwashes, and oral gels. In certain embodiments, the compositions of the invention form a rapid and continuous reaction with body fluids (e.g., saliva) to promote the immediate and long- term release of Ca and P ions to produce a stable crystalline layer deposited onto and into the dentin tubules for the immediate and long term reduction of dentin hypersensitivity and tooth surface remineralization.

Abstract:
The invention includes methods of cleaning an oral surface, maintaining oral health and/ or increasing oral health. Such methods encompass contacting an oral surface with a primary oral care composition at least once daily, and contacting the oral surface with a periodic oral care composition at least once within a period of about 42 days. The periodic oral care compositions suitable for use in the method comprise a first abrasive having an Einlehner hardness of greater than about 5 mg loss per 100,000 revolutions and a second abrasive having an Einlehner hardness of less than about 5 mg loss per 100,000 revolutions. In the periodic oral care compositions, the ratio of the first abrasive to the second abrasive is about 1:1.6 to about 1.6:1. The periodic oral care compositions are characterized by a pellicle cleaning ratio of greater than about 100 and a radioactive dentin abrasion of less than about 200. Additionally or alternatively, the methods may include those where the second abrasive comprises silica and has an oil of absorption of greater than about 90 cm 3 /100g and/ or an Einlehner hardness of less than about 5 mg loss per 100,000 revolutions. The ratio of the first abrasive to the second abrasive may be about 1:1.6 to about 1.6:1. The total amount of the first and second abrasives present in the oral composition may be greater than about 25 % by weight of the composition and/ or the oral composition has a pellicle cleaning ratio of greater than about 100 and a radioactive dentin abrasion of less than about 200.
Abstract:
A composite comprising a silicone compound sorbed onto a porous cross-linked polymer. This composition can be included in an oral care composition and inhibit bacterial adhesion on an oral surface.
Abstract:
Oral compositions comprising a first and a second abrasive are provided. The first abrasive preferably has an Einlehner hardness of greater than about 5 mg loss per 100,000 revolutions, and the second abrasive preferably has an Einlehner hardness of less than about 5 mg loss per 100,000 revolutions. A ratio of the first abrasive to the second abrasive ranges from about 1:1.6 to about 1.6:1, and the first and second abrasives are preferably present in the oral composition at an amount of about 13% to about 21 % by weight, respectively. The pellicle cleaning ratio of the oral composition is greater than 100 and the radioactive dentin abrasiveness is preferably less than 200, and in certain embodiments, preferably less than about 175. Methods of using the oral compositions are also provided.
Abstract:
A single phase whitening dentifrice that includes (i) a whitening agent selected from the group consisting of hydrogen peroxide, a bound peroxide and a solid peroxide (ii) an abrasive and (iii) a substantially anhydrous orally acceptable carrier, for example, polyethylene glycol. The bound peroxide may be hydrogen peroxide and a polymer and/or any peroxide compound and a porous cross-linked polymer, such as polymers of polyvinyl pyrrolidone, polyacrylates, a polymethacrylates, and a polyitaconates. The solid peroxide may be sodium perborate or urea peroxide. The invention also provides methods of whitening the tooth surfaces by contacting the surface with the composition.
