Abstract: Dental curing light systems capable of monitoring the degree of curing of polymerizable dental material. A monitoring light source delivers visible monitoring light at one or more different visible wavelengths and a visible light detector detects the monitoring light diffusely reflected by the polymerizable dental material. The monitoring light has a wavelength of maximum emission (λmax-mon) that does not effectively induce polymerization of the polymerizable dental material. Change in intensity of the monitoring light reflected from the polymerizable dental material is used to determine when a selected degree of curing is reached in the polymerizable dental material.

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.

Abstract: Dental compositions and methods of formulating a dental composition are described. In one embodiment, the dental composition comprises a polymerizable resin comprising one or more ethylenically unsaturated monomers or oligomers and nanoparticles. The nanoparticles have a refractive index of at least 1.600 and an average discrete or aggregate particle size of no greater than 100 nm. The dental composition further comprises inorganic metal oxide filler having a discrete or aggregate average particle size of at least 200 nm. The nanoparticles are present at a concentration to provide a refractive index differential between the cured polymerizable resin and inorganic metal oxide filler such that the contrast ratio of the dental composition is at least 40.
