Abstract: A curable composition that includes a urethane multifunctional (meth)acrylate, an inorganic filler having a primary particle dimension of at least 200 nm, a photoinitiator system that can be activated by electromagnetic radiation in the range of 340-550 nm, a reactive diluent, and a reinforcing silica having a primary particle dimension of 100 nm of less. The sum of the absolute value of the difference in the refractive index of the filler and the refractive index of the composition cured without filler plus the birefringence of the filler is 0.054 or less, i.e. 0.054≥|nfiller−nmatrix|+δfiller, where nfiller is the refractive index of the filler, nmatrix is the refractive index of the composition cured without filler, and δfiller is the birefringence of the filler.

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. sealant) composition to a tooth structure.

Abstract: Presently described are dental compositions comprising one or more fatty mono(meth)acrylates, methods of use, dental articles, and methods of making dental compositions. It has been found that a relatively low concentration of a fatty mono(meth)acrylate can improve the handling characteristics of a dental composition by reducing the tendency of the composition to stick to a dental instrument and/or by reducing the tendency of a dental composition to string when being manipulated by a dental instrument. In one embodiment, a hardenable dental composition is described comprising a polymerizable resin composition comprising at least one multifunctional ethylenically unsaturated monomer; 0.2 to 10 wt-% of one or more fatty mono(meth)acrylate monomers; and at least 50 wt-% of inorganic oxide filler.

Abstract: The present disclosure provides a composite material, a method of making and using the composite material and dental products made by hardening the composite material. The composite material includes a polymerizable component, ceramic fibers and nanoclusters. Each of the ceramic fibers of the composite material has a length and where the length of fifty percent of the ceramic fibers, based on a total number of the ceramic fibers, is at least 50 micrometers and the length of ninety percent of the ceramic fibers, based on the total number of the ceramic fibers, is no greater than 500 micrometers. The composite material can also include discrete non-fumed metal oxide nanoparticles. The composite material can be hardened to become any one of a dental restorative, a dental adhesive, a dental mill blank, a dental cement, a dental prostheses, an orthodontic device, an orthodontic adhesive, a dental casting material or a dental coating.
