Abstract: Dental resin cement materials having unique handling properties are provided that comprise a) filler, b) polymerizable resin, and c) a polymeric handling modifier that is dispersed in the polymerizable resin at 25° C. and that has a molecular weight of between about 500 and 100,000. Components a) b) and c) are present in an amount effective to achieve a Viscosity vs Shear Rate Curve that fits a power law model of F(x)=AxB. The correlation value of the material to this curve is greater than 0.85 for both the increasing and decreasing shear rate curves, and the value of B is less than about ?0.01. Resin cements are also provided that comprise acid functionality and water, but which do not comprise an acid reactive filler. Such cements may be self etching, thereby avoiding the need to carry out a separate acid etch step.

Abstract: The present invention provides a method of luting a provisional prosthetic device to tooth structure using glass ionomer cement systems having reduced bulk shear adhesion. The invention also provides a kit for luting a prosthetic device to tooth structure. The kit contains at least three containers of glass ionomer luting cement compositions. The kit advantageously can be utilized for providing both a provisional and a permanent luting cement depending upon which components are admixed.

Abstract: A method for adhering amalgam to a dental surface comprising the steps of a) etching the dental surface with acid, b) applying a treatment composition comprising an aromatic sulfinate salt to the etched dental surface, c) applying a priming solution containing a film-former to the treated dental surface, d) applying a chemically curable dental adhesive to the primed dental surface, and e) applying amalgam to the adhesive-coated dental surface. The chemically curable adhesive comprises an oxidizing agent and a reducing agent. The oxidizing agent is present in an amount sufficient to interact with said aromatic sulfinate salt to achieve higher adhesion to the dental surface than a like method not comprising an aromatic sulfinate salt in the treatment composition.

Abstract: A method for adhering non-amalgam dental restorative materials to a dental surface comprising the steps of a) etching the dental surface with acid, b) applying a treatment composition comprising an electron donor to the etched dental surface, c) applying a priming solution containing a film-former to the treated dental surface, d) applying a chemically curable dental adhesive to the primed dental surface, and e) applying non-amalgam dental restorative material to the adhesive-coated dental surface. The treatment composition comprises an electron donor compound selected such that the dental restorative has a higher Adhesive Shear Bond Strength than a like method without said electron donor compound.
