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.
