Abstract: A composition of matter includes one or more functionalized vinylbenzyl components of the formula wherein n is an integer equal to or greater than 1 covalently connected to one or more R functional components; the one or more R functional groups selected from a group including one or more hydroxyl methyl (—CHOH—) moieties and/or derivatives thereof, one or more ethoxy (—CH2—CH2—O—) moieties and/or derivatives thereof, and one or more benzene derivatives; and ether links that connect the functionalized vinylbenzyl components and the R functional components.

Abstract: A multi-functional self-healing dental composite may intrinsically repair the micro-crack and prevent the crack from propagating to catastrophic failure, thus significantly extending the service life of the restorative material. The self-healing dental composite includes a dental resin matrix, fillers, healing powder, and healing liquid containing micro-capsules distributed throughout the matrix. Each of the micro-capsules have a silica she formed by the hydrolysis condensation of TEOS in the presence of an aqueous solution of a healing liquid. The healing liquid includes a homo-polymers(s) and/or copolymer(s) of carboxylic acid(s). The healing powder particles distributed throughout the resin matrix, and include alumina, silica and other elements. The self-healing may be triggered automatically as a result of micro-cracking, induced by thereto/mechanical fatigue. During the self-healing process, antibacterial agents may be released to provide protection of the composites against cariogenic bacteria.

Abstract: A polymeric composition comprising modified-TiO2 nanoparticles, with or without a solvent, and polymer precursors; wherein the modified-TiO2 nanoparticles comprise titanium dioxide nanoparticles modified with a short-chain unsaturated compound comprising 2 to 10 carbon atoms. The polymeric composition may be used in dental compositions such as dental adhesives, dental composites, and dental sealants.
