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 homogenous 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.

Ladite composition adhésive comprend un solvant organique volatil, un ou plusieurs composés (méth)acrylate polymérisables contenant éventuellement des charges, et un photoamorceur de polymérisation. Le constituant adhésif peut également être un mélange pratiquement homogène constitué d'un ou plusieurs composés (méth)acrylate polymérisables et d'une quantité efficace d'un photoamorceur, sans solvant. Le constituant activateur comporte un sel sulfinate aromatique et un solvant. Un procédé permettant de faire adhérer un élément de restauration à une surface dentaire consiste à préparer ladite surface en vue de la restauration, à appliquer un mélange constitué d'un adhésif et d'un activateur sur la cavité ainsi préparée, ce qui crée une surface de cavité à revêtement, et à appliquer un élément de restauration dentaire direct ou indirect sur ladite surface de cavité.
