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.

The present invention relates to a container (100) for producing a self-curing or dual-curing dental synthetic material composition (200), which container comprises a deformable wall (101), having a first synthetic material component (103-1); and a second synthetic material component (103-2) for curing the synthetic material composition (200) or starting a curing reaction.

A phosphorous compound such as STMP is used as a cross-linking agent while making a starch nanoparticle in an emulsion process. Negative charge of the nanoparticle is reduced or reversed by adding cations and/or cationizing the starch optionally while forming the nanoparticles. Anionic active agents, such as fluoride or fluorescein, are optionally incorporated into the nanoparticle during the formation process. For example, a fluoride salt can also be used, which promotes the crosslinking reaction while also providing fluoride in the nanoparticle. The retention of both calcium and fluoride in the nanoparticle is improved when both salts are used. Alternatively, the nanoparticle may be used without added calcium and/or fluoride. The nanoparticles may be useful for tooth remineralization, the treatment of dentinal hypersensitivity, to treat caries, or as a diagnostic agent to locate carious lesions.

The invention relates to a dental composition comprising a resin matrix, a filler matrix in an amount of at least 25 wt. % with respect to the weight of the dental composition, an initiator system, the resin matrix comprising polymerizable monomer(s) comprising two (meth)acrylate moieties connected to a brominated resorcinol, catechol, tyrosol, benzoic acid or phenol moiety. The invention relates also to a dental milling block comprising this composition in its hardened stage.

The invention relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit comprising a Paste A and a Paste B, Paste A comprising water, acid-reactive inorganic filler A, phyllo silicate(s), Paste B comprising water, poly-acid, non acid-reactive filler B, optionally chelating agent. The invention also relates to a hardenable composition obtainable by combining the pastes of the kit or parts and to the use of such a composition as or for preparing a dental cement, dental filling material, dental core build up material or dental root channel filling material.
