Abstract: An article and a method of making the article. The article can include a conformable matrix comprising a mixture of collagen and bioactive glass; wherein the article is a conformable wound dressing. The method includes dissolving collagen in an acid solution; adding bioactive glass to the acid solution; mixing collagen and bioactive glass to increase or decrease the pH of the solution; and forming a mixture of collagen and bioactive glass.

Abstract: A method of applying a two-part dental sealant is described comprising providing a syringe device (1) comprising a cartridge (10) including first and second chamber. The first chamber contains a first part of a dental sealant comprising a (meth)acrylate resin and an oxidizing curing agent. The second chamber contains a second part of a dental sealant comprising a (meth)acrylate resin and a reducing curing agent that reacts with the oxidizing curing agent of the first chamber. The first and/or second part of the dental sealant further comprise a single component or multiple components that neutralize acid and promote remineralization. The syringe device comprises a dispensing nozzle (17) comprising a static mixer and an outlet at one end of the cartridge and a plunger (20) at the opposing end of the cartridge. Also described is a kit for storing and applying the dental sealant is described.

Abstract: Provided is an addition-fragmentation agent of the formula (I) where Ramine comprises a tertiary amine group; R2 linking group of valence a+2; Z is an ethylenically unsaturated polymerizable group; and subscript a is 0 or 1.

Abstract: A hardenable (e.g. dental) compositions is described comprising an encapsulated material. The encapsulated material comprises a basic core material and an inorganic shell material having certain viscosity criteria. Also described are dispensing devices and kits are described comprising a hardenable (e.g. dental) composition comprising a liquid material and an encapsulated material wherein the encapsulated material comprises a basic core material and an inorganic shell material comprising a metal oxide surrounding the core. The dispensing devices and kits can facilitate the methods of applying the hardenable composition. The hardenable or hardened (e.g. cured) composition can provide various technical effects such as a delayed release of a basic core material, a delayed increase in basicity, promoting remineralization of a tooth or bone structure, and increasing the average alkaline phosphatase (ALP) activity of pulp cells. In some embodiments, the composition is a dental (e.g.

Abstract: A (e.g. hardenable dental) composition is described comprising (e.g. a first part comprising) an encapsulated material wherein the encapsulated material comprises a basic core material and an inorganic shell material comprising a metal oxide surrounding the core; and (e.g. a second part comprising) water or an acidic component. Also described is an encapsulated material (e.g. suitable for use in a biological carrier material) comprising a basic core material and an inorganic shell material comprising a metal oxide surrounding the core.
