Patent ID: 7214726

Claim:
A method for providing a dental composition comprising providing a paste/paste two-part self-adhering dental composition, a first paste comprising water and (a) at least one acidic compound comprising a homopolymer/copolymer of an α,β-unsaturated carboxylic acid; (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 having a mean particle size of less than 50 microns; (d) at least one oxidizing agent; and a second paste comprising (e) at least one polymerizable monomer without any acidic group which is either the same as (b) or different from (b) where the polymerizable group is selected from the group consisting of an acrylate, a methacrylate and a vinyl group; (f) at least one finely divided filler which is either the same as (c) or is different from (c); (g) at least one reducing agent; providing instructions for mixing the two pastes and applying the mixed composition to a dental substrate wherein the ratio of the first paste to the second paste is greater than 1:1 (by volume).
