The present invention provides a dental composition that exhibits excellent long-lasting antibacterial activity even as a cured product, and that excels in aesthetic quality with no discoloration occurring in water or in hydrogen sulfide. The present invention relates to a dental composition comprising a platinum nanoparticle (a) uncoated with a colloidal protective material.

The present invention relates to a copper alloy for dental prosthesis and specifically, to a copper alloy for dental prosthesis having such color and luster that the copper alloy can be used as a substitute for a gold alloy and having excellent resistance to corrosion, wherein the copper alloy comprises, in wt %, 7-10% of Al, 1-2.5% of In, 1-2.5% of Sn, 2-4% of Fe, 2-3.5% of Ni, 2.5-4% of Mn, 2-5% of Zn, and the balance Cu.

A high molecular weight polyethylene polymer is formulated so that the polymer is capable of being injection molded. The polyethylene polymer has a Viscosity Number of greater than about 400 ml/g and has a melt flow rate of greater than about 0.9 g/10 min. The polyethylene polymer is of high purity and is particularly well suited for producing medical products.

The present disclosure concerns a mineralized tissue adhesive or filler composition comprising an intermolecular crosslinked osteopontin protein for treating an exposed surface of a mineralized tissue. The mineralized tissue adhesive or filler composition can be added directly on the exposed surface of the mineralized tissue or on a layer of monodisperse OPN protein which has been deposited on the exposed surface of the mineralized tissue. The present disclosure also includes methods and kits of using the mineralized tissue adhesive or filler composition especially in dental applications. The present application also provides dental coatings, fillings, bondings and veneers comprising the mineralized tissue adhesive or filler composition described herein.

Silver sulfadiazine-immobilized inorganic fillers are described, and their synthesis is presented. The fillers are believed to have utility in dental composites and dental adhesives to achieve potent, long-term, and none-leaching antimicrobial effects.
