Abstract: A dental adhesive composition has an adhesive component and an activator component. The adhesive composition has a volatile organic solvent component, one or more polymerizable (meth)acrylate compounds optionally containing fillers, and a polymerization photoinitiator. The adhesive component may also be a substantially homogeneous mixture of one or more polymerizable (meth)acrylate compounds and an effective amount of a photoinitiator, without a solvent. The activator component includes an aromatic sulfinate salt and an activator component solvent. A method for adhering a restorative to a dental surface includes preparing the surface for restoration; applying a mixture of an adhesive component and an activator component to the prepared cavity, thereby forming a coated cavity surface; and, applying a direct or indirect dental restorative to the coated cavity surface.

Abstract: A self curing activator for chemical polymerization of the interface of a dental bonding agent and a self curing or dual curing dental cement or restorative, includes an aryl borate compound, a polymerizable monomer, an optional acidic compound, an amine compound which exhibits a catalytic action, an organic peroxide containing material, and a metal compound wherein said metal compound promotes the decomposition of the organic peroxide.

Abstract: The invention provides a container enclosing an applicator and a dental composition including a volatile organic solvent. The container is sealed. The volatile organic solvent is effectively retained within the container, even after storage at about 43° C. for one week. Preferably the container is made of a copolymer of a cycloolefin and an open chain olefin.

Abstract: A composition of macrocyclic oligomer with at least one polymerizable group, (meth)acrylate, for example.

Abstract: The invention provides dental cement compositions and methods of using them for binding hard tooth material, metal and ceramic. The cement compositions include shelf stable complexes of ethylenically unsaturated monomers reacted with cations. The cements have superior adhesion to tooth without separately acid etching dentin or enamel. Compositions of are useful as dental luting cements, liners, pit and fissure seal bases and restoratives.
