Abstract: Described herein are oral care compositions comprising an orally acceptable carrier; an abrasive system comprising a calcium-based abrasive; and a core shell silica particle comprising; a metal silicate; and a silica particle comprising a core having a surface; wherein the metal silicate is chemically bound to a surface of the silica core; and wherein the metal silicate comprises a silicate of a divalent metal ion. Methods of making and using these compositions are also described.

Abstract: An in vitro method for demonstrating the stain removal efficacy of an oral care composition comprising (a) providing a substrate, (b) providing a staining solution, (c) providing a treatment solution comprising the oral care composition, (d) immersing the substrate in the staining solution, (e) removing the substrate from the staining solution, (f) evaluating the color of the stained substrate, (g) applying the treatment solution to the substrate and (h) evaluating the color of the treated substrate, wherein the staining solution comprises coffee is provided.

Abstract: Described herein are compositions comprising antibacterially effective amounts of a compound of Formula (I): or a salt thereof in which R1 and R2 are each independently (C1-C6) alkyl or (C2 C6) alkenyl, and a carrier. Suitable carriers include orally acceptable carriers and dermatologically acceptable carriers. The disclosed compositions include oral care and personal care compositions useful for treating or preventing oral and skin conditions, respectively.

Abstract: The present application provides a tooth anatomy model comprising: a first layer representing tooth dentin, said first layer being made of a first material; and a sensor system associated with a surface of the first layer, which system is adapted to sense at least one of temperature and air pressure. The present application also provides a method of demonstrating tooth hypersensitivity using a tooth anatomy model.
