The present invention relates to polymeric composites comprising inorganic fillers and organic, or organometallic, polymers. The filler compositions are used in the preparation of inorganic-organic polymeric composites, and, in particular, light curable composites. The composite fillers are used in dental applications, such as tooth restorations, for example, cavity fillings, adhesive compositions, veneers, crowns, bridges and teeth replacements. The inventive composition is a composite filler comprising porous inorganic particles having a diameter of 2-25 microns and a polymer occupying the pores of the porous inorganic particles, wherein the composite filler has a diameter of 2-25 microns.

The present disclosure features adhesive compositions and methods of use thereof related to the medical, veterinary, and dental fields.

The present invention provides a one-part dental adhesive that exhibits excellent adhesive properties to both enamel and dentin and that has high storage stability and ambient-light stability. The present invention is a one-part dental adhesive including 1 to 30 weight % of a phosphoric acid group-containing monofunctional (meth)acrylate compound (a), 10 to 50 weight % of a water-soluble polymerizable monomer (b), 5 to 50 weight % of a hydrophobic crosslinkable (meth)acrylate compound (c), water (d), and a polymerization initiator (e). The water-soluble polymerizable monomer (b) includes a combination of a monofunctional (meth)acrylamide compound (b-1) having a particular structure and a water-soluble crosslinkable (meth)acrylic monomer (b-2). The weight ratio between the monofunctional (meth)acrylamide compound (b-1) and the water-soluble crosslinkable (meth)acrylic monomer (b-2) is 10:1 to 1:5.

An acrylic dental composite filling material and a production method thereof are provided. The acrylic dental composite filling material includes a light-cured and polymerizable organic compound, a photoinitiator, and a supportive phase system, where the light-cured and polymerizable organic compound is a mixture of BisGMA and TEGDMA, the photoinitiator is at least one of CQ, diphenyl(2,4,6-trimethylbenzoyl) phosphine oxide, 1-phenyl-1,2-propanedione, and 4-EDMAB.

The present invention provides a tooth surface treatment agent and a tooth surface treatment kit to form a uniform, high-strength layer composed of apatite on tooth surface and to repair minute recesses on the tooth surface.

The tooth surface treatment agent includes: a liquid with a pH of 1.0 to 3.0 containing an organic acid; and hydroxyapatite particles with a particle diameter of 200 nm or less. The tooth surface treatment kit includes: a first treatment agent that is a liquid having a pH of 1.0 to 3.0 and containing an organic acid, which is accommodated in a first container; and a second treatment agent including hydroxyapatite particles having a particle diameter of 200 nm or less, which is accommodated in a second container different from the first container. The tooth treatment agent is prepared by mixing the first and second treatment agents, and is applied to the tooth surface.

An endodontic filling material comprising a biodegradable thermoplastic polymer. A bioactive substance may also be included in the filling material. The thermoplastic polymer acts as a matrix for the bioactive substance. The composition may include other polymeric resins, fillers, plasticizers and other additives typically used in dental materials. The filling material is used for the filing of root canals.
