The invention relates to the application of photon energy to energize dental materials to enhance their physical handling characteristics, efficacy, ability to be delivered, reactivity, polymerization, and/or post-cure mechanical properties, among other attributes.

A dental polymerizable composition including a glass powder and a (meth)acrylate is provided. The glass powder includes zinc, silicon, and fluorine and is substantially free of aluminum.

In one aspect of the present invention, a dental cement contains a glass powder, wherein the glass powder contains zinc, silicon, and fluorine and does not substantially contain aluminum.

Disclosed is a dental adhesive including a polymeric adhesive and a nanofiller dispersed in the polymeric adhesive, the nanofiller being constituted by graphene nanostructures which are properly dispersed inside the polymer adhesive and over the surface of the adhesive layer without formation of agglomerates, so that the dental adhesive exhibits significant antimicrobial and antibiofilm properties against pathogens of the oral cavity.

Provided herein are novel compositions for the restoration of demineralized tissues, such as dentin which has been demineralized by tooth decay. The remineralization agent comprises a bioactive ceramic component and a polyanionic macromolecular component, which may be admixed and applied to the target tissue and which will subsequently set to produce a remineralizing solid. The remineralizing solid will produce nanodroplets of mineral precursor solution, which such nanodroplets can infiltrate demineralized collagen matrices and which will form hydroxyapatite crystals therein by polymer-induced liquid precursor processes. The scope of the invention encompasses novel compositions and methods of treating demineralized tissues.

A resin block that can be favorably used for obtaining dental prosthetics through the milling work, containing very little voids, having excellent property for being cut, exhibiting excellent appearance and mechanical strength, and without permitting the formation of defective products. The resin block contains a thermoplastic resin having a fluidizing temperature in a range of 310 to 500 C. and inorganic particles in an amount of 30 to 150 parts by mass per 100 parts by mass of said thermoplastic resin. The inorganic particles are at least one kind of inorganic oxide particles selected from the group consisting of silica particles, silica composite particles of silica and other metal oxides, titania particles, and titania composite particles of titania and other metal oxides. The resin block has a thick portion of a thickness of at least not less than 5 mm, and does not contain any void whose length is not less than 1.0 mm.

Described herein are dental treatment compositions, more particularly, a dental varnish composition useful in effective fluoridation, enhancement of remineralization the tooth enamel, and hypersensitivity through occlusion of dentine tubule. The dental varnish composition includes a hydrogel system and at least one fluoride source, wherein the dental varnish is water soluble. The hydrogel system includes at least one polyphenol having at least one phenol group, at least one polymer, and a metal ion. Described herein are also methods of making such dental varnish composition.
