Abstract: A method of making a flowable, dried agglomerated nutrient medium is provided. The method comprises introducing a nutrient component comprising a powdered nutrient, and an agglomeration liquid, into an agglomerator comprising a flow-through-type agglomeration chamber, wet-massing the nutrient component with the agglomeration liquid in the agglomeration chamber for a predetermined period of time to form agglomerated nutrient medium particles, and exposing the agglomerated nutrient medium particles to drying conditions for a period of time to form the dried, agglomerated nutrient medium. The nutrient component facilitates the growth of a microorganism. Compositions, articles, and kits comprising the flowable, dried agglomerated nutrient medium are also provided.

Abstract: An oral composition and a method of delivering an oral composition to a dental structure are described. The oral composition can include a solvent; an acidic copolymer having acidic acrylate monomeric units, acidic methacrylate monomeric units, or a combination thereof; a neutral copolymer having neutral acrylate monomeric units, neutral methacrylate monomeric units, or a combination thereof; and optionally an active agent. The acidic and neutral copolymers can be dissolved in the oral composition and the oral composition can form a film on a surface when contacted with an aqueous solution.
