The present invention provides self-adhesive compositions that include a plurality of acidic compounds. The self-adhesive compositions are useful for applications including, for example, restoring dental structures and adhering orthodontic appliances to teeth.

Self-adhesive compositions including a plurality of acidic compounds

Methods and compositions including an aqueous liquid that includes an acid-sensitive dye are disclosed for use in dental and orthodontic procedures. The aqueous liquid can be useful for providing a visible color change to indicate contact with acidic materials including, for example, etching compositions, self-etching adhesives, and self-adhesive compositions.

Dental methods, compositions, and kits including acid-sensitive dyes

The present invention is directed to compositions containing one or more polymerizable bisphosphonic acids and optionally one or more additional polymerizable components.

Compositions including polymerizable bisphosphonic acids and methods

An adhesive composition including an etchant for a hard tissue surface, at least one multifunctional crosslinkable (meth)acrylate monomer with a functionality greater than 4, and water. The adhesive composition is a water-in-oil emulsion.

Adhesive composition for hard tissue

The present invention is directed to dental compositions that can be used as adhesives for bonding a dental material to a dental structure surface and/or as a dental restorative material. The dental composition is preferably applied to a dental structure surface under conditions effective to etch the dental structure surface.

Self-etching emulsion dental compositions and methods

Self-adhesive dental compositions and methods

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&#xb0; 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)=Ax. 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 &#x2212;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.

Dental resin cements having improved handling properties

Method for adhering to hard tissue

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.

Method for bonding amalgam to dental surfaces

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.

Method for bonding non-amalgam restorative materials to dental surfaces

The invention provides a pretreatment method and primer that is applied directly to the hard tissue. The invention has particular utility for adhering to or coating sclerotic dentin and cervical enamel or for adhering to or coating hard tissue in a high humidity environment. The primer enables formation of extremely strong bonds to dentin. The method comprises the steps of:
