Abstract: A dental composite composition is disclosed that includes a polymerizable resin, filler particles, and at least one polymerizable stable radical. A variety of polymerizable stable radicals may be employed, including those that have a 2,2,6,6-tetramethylpiperidinyl-1-oxyl moiety. Compositions as described herein exhibit excellent mechanical strength, hardness, and flexural modulus, while also significantly decreasing shrinkage stress caused by polymerization.

Abstract: A luminescent coating is disclosed that is used to dimensionally control the curing of a photocurable agent placed in close contact with the coating. The coating is applied at the interface of structures, such as brackets and prosthetics, or may be applied directly on a curable material for use in 3D printing, at the location where bonding material is needed to be cured. The luminescent coating irradiates from its structure the curing radiations necessary to photopolymerize the resin in response to a first radiation irradiated on its structure of a different wavelength.

Abstract: A dental restorative composite and a method of curing the composite are disclosed in which the composite includes a polymerizable organic resin, a radiation activated initiator having an activation wavelength, an inert filler; and luminescent crystals, wherein the luminescent crystals emit radiation at a predetermined wavelength matching the initiator activation wavelength when the luminescent crystals are irradiated with radiation having a wavelength longer than the activation wavelength, the luminescent crystals being up-converting particles that result in those particles emitting radiation at a wavelength that initiates curing.
