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.

Un procédé de fixation de matériaux de restauration dentaire sans amalgame sur une surface dentaire consiste: a) à attaquer à l'acide la surface dentaire, b) à appliquer une composition de traitement comprenant un donneur d'électrons sur la surface dentaire attaquée à l'acide, c) à appliquer une solution d'amorçage contenant une substance filmogène sur la surface dentaire traitée, d) à appliquer un adhésif dentaire, durcissable chimiquement, sur la surface dentaire amorcée, et e) à appliquer un matériau de restauration dentaire sans amalgame sur la surface dentaire revêtue de l'adhésif. La composition de traitement comprend un composé donneur d'électrons, sélectionné de façon à ce que le matériau de restauration dentaire ait une résistance d'adhésion par cisaillement supérieure à celle d'un procédé analogue sans le composé donneur d'électrons.
