Dental crowns and methods of making the same. The dental crown may include a metal shell shaped to cover a portion of a tooth of a patient; a coating retention metal layer diffusion bonded to the metal shell, wherein an interface between the coating retention layer and the metal shell comprises a plurality of interstitial regions; and a composition on the coating retention layer and within the plurality of the interstitial regions to bond the coating composition to the metal shell.

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. sealant) composition for application to a tooth structure.

A method of applying a two-part dental sealant is described comprising providing a syringe device () comprising a cartridge () 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 () comprising a static mixer and an outlet at one end of the cartridge and a plunger () at the opposing end of the cartridge. Also described is a kit for storing and applying the dental sealant is described.

Novel stress-reducing crosslinking oligomers that have application in dental restoratives, thin films, hardcoats, composites, adhesives, and other uses subject to stress reduction are described. The addition-fragmentation process of crosslinking results in a chain-transfer event that provides novel polymers that may be further functionalized. In addition, the addition-fragmentation oligomer comprises pendent functional groups that bond to a substrate by forming an ionic or covalent bond, or etch the substrate by chemically removing some material from the substrate.

Addition-fragmentation oligomers

The invention relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit of parts comprising a Powder Part P and a Liquid Part L, Powder Part P comprising: acid-reactive inorganic filler, Liquid Part L comprising: water, complexing agent, polyacid, either the Powder Part P or the Liquid Part L or the Powder Part P and the Liquid Part L comprising non-aggregated nano-sized particles based on silica or alumina, the composition obtained by combining the components of Powder Part P and Liquid Part L before hardening comprising the components in the following amounts: non-aggregated nano-sized particles: from 0.1 to 15 wt.-%, acid-reactive filler in an amount from 50 to 75 wt.-%, polyacid: 7 to 20 wt.-%, complexing agent: 0.5 to 3 wt.-%, water: 5 to 18 wt.-%, wt.-% with respect to the weight of the whole composition.
