Abstract: A composition and method of treating a dental tooth surface and adhering a restorative material to the treated dental tooth surface is provided. A liquid composition is applied to at least the portion of the tooth to form a treated surface. The composition includes at least 50 percent by weight of a volatile organic solvent, at least 15 percent by weight of one or more polymerizable acrylate compounds and an effective amount of a photoinitiator. At least a portion of the polymerizable compounds are multifunctional polymerizable compounds having at least three acrylate moieties. The polymerizable compounds are substantially soluble in the solvent. The composition is adapted to form a polymeric material which is adapted to adhere to dentin with a bond strength of at least 12 Mpa. Restorative material is then adhered to the treated surface with a bond strength of at least about 12 MPa.

Abstract: A method is provided for clinical retention of restorative material by a natural tooth. A first portion of photopolymerizable liquid primer/adhesive dental composition is applied to a tooth surface. After leaving the first portion of the liquid composition on the tooth surface undisturbed for at least 15 seconds on the tooth surface air is conveyed against the first portion of the liquid. The light is impinged on the first portion of the liquid composition whereby at least a portion of the first portion of the liquid composition polymerizes to form a first coating on the tooth. A second portion of the liquid composition is applied to the first coating, and air is substantially immediately conveyed to the second portion of the liquid composition.

Abstract: The invention provides dental composite compositions formed by mixing a curable liquid composition with a powder in preselected proportions. The composite compositions formed are useful as cement, liner, base, restorative, pit and fissure sealants, and/or core build-up material, etc. having improved adhesion to dentin. These composite compositions include polyalkenoic acid, filler which provides elutable cations which are reactive with the polyalkenoic acid and fluoride ion, water to provide for elution of cations reactive with polyalkenoic acid, polymerizable monomer and/or prepolymer composition, unsaturated organic acid having 1 or more polymerizable groups and a catalyst system for polymerization. Optionally the composites include inert reinforcing filler for strength, aesthetics, and radiopacity.

The cement compositions include polymerizable acid reactive ethylenically unsaturated monomers, and a source of cations reactive therewith, to further crosslink the resulting polymer. The cements have superior adhesion to tooth without separately acid etching dentin or enamel. Compositions of are useful as dental luting cements, liners, bases and restoratives.

Abstract: A biologically compatible adhesive dental primer that is shelf stable as a single component adhesive and includes a mixture of an adhesive promoting and polymerizable monomer system having a free radical polymerizable monomer or prepolymer having ethylenic unsaturation and a phosphorus containing adhesion promoter which is free from halogen atoms bonded directly to a phosphorus atom, and optionally a free radical polymerization catalyst, and an accelerator for the catalyst.

Abstract: A method of detecting dentin is provided. Also provided is a method of repairing a tooth in which dentin is detected using a substance that stains protein, and is thereby clearly delineated from enamel, the enamel is then selectively acid etched, taking care that none of the acid from the etching procedure contacts dentin, and composite filling material is applied to the tooth. The use of a composition for staining dentin is also provided.
