ABSTRACT:
A method for providing a dental composition comprising providing a paste/paste two-part self-adhering dental composition comprising(a) at least one acidic compound containing at least one acidic moiety selected from the group consisting ofwhere R is an alkyl or aryl group;(b) at least one polymerizable monomer without any acidic group where the polymerizable group is selected from the group consisting of an acrylate, a methacrylate and a vinyl group;(c) at least one finely divided filler;(d) a reducing agent; and(e) an oxidizing agent;and providing instructions for mixing the two pastes immediately prior to application where the ratio of a first paste containing (a) or a higher concentration of (a) to a second paste not containing (a) or containing a lower concentration of (a) is greater than 1:1 (by volume). The method also includes mixing the two pastes and applying the mixed composition to a dental substrate.
