A dose applicator for preparing a mixture at a point of use includes a housing defining an interior and an opening. First and second ampoules are contained in the interior, wherein the first ampoule contains a first component and the second ampoule contains a second component comprising one or more antifungal agent. An applicator tip is secured in the opening so that when the first and second ampoules are broken, the first and second components mix to form the mixture and the mixture can egress from the application tip.

A family of cobalt based dental alloys suitable for PFM and SLM applications that do not exhibit ferromagnetism and that are capable of meeting the ADA requirements for a noble alloy are provided. The dental alloys comprise at least 25 wt. % of noble metals selected from either platinum alone or a combination of platinum and ruthenium, and from 23 to 32 wt. % chromium. Additional additive materials may be included in concentrations up to 3 wt. %. The ruthenium optionally comprises up to 8 wt. %, and in some embodiments from at least 5 wt. % to 8 wt. % of the noble metals such that the dental alloys are capable of meeting the ADA requirements for a noble alloy.

Antimicrobial polymer composite materials are disclosed that are suitable for making oral devices used in dental applications, such as denture bases. Acrylic resin composite materials comprising antimicrobial polymers and antimicrobial fillers provide reduction in common oral microorganisms after long-term aging, with reduced release rate of antimicrobial agents from the composite material. Antimicrobial polymers are prepared from compositions comprising acrylate and/or methacrylate monomers and polymerizable quaternary ammonium silicon-containing compounds.

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.

Described herein are directed to dental filler particles and methods of making the same. The dental filler particles include a polymer coating with a plurality of ethylenically unsaturated groups on the surface of the coating. Also described herein are dental restorative materials comprising the particles.

A medical device or solution for treating dental discomfort by at least partially occluding dental tubules is disclosed. The medical device or solution contains a polysaccharide or other biocompatible polymer with an antimicrobial metal, antimicrobial metal compound, or antimicrobial metal ion bound to a biopolymer. The medical device or solution further comprises at least one soluble antimicrobial. The soluble antimicrobial may be a water soluble metal iodide, water soluble metal fluoride, or a water soluble metal chloride encompassed with the nanogel. The medical device may be a solution of a chitosan with a nanoparticle of silver fluoride on the chitosan and at least one of a sodium fluoride or silver fluoride. The solution may be water based solution. Methods of applying the medical device or solution are also disclosed.

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.
