ABSTRACT:
A bonding adhesive for dentistry and a method for preparing the surface of dentin, enamel, or other natural or industrial substrates containing or capable of binding metallic ions, for adhesion of composite materials or resins. First, an aqueous solution of phosphoric acid or a mixture of phosphoric and nitric acids along with aluminum oxalate, or phosphoric acid alone, is applied to the surface. Second, a solution comprising a solvent and at least one compound selected from the group consisting of (1) N-phenylglycine in a mixture with the alkali metal salt of N-phenylglycine, (2) a mixture of the adduct of the alkali salts N(p-tolyl)glycine and glycidyl methacrylate, with the mixture N(p-tolyl)glycine and glycidyl methacrylate (3) the addition reaction product of the alkali metal salt of N-phenylglycine and glycidyl methacrylate, and N-phenylglycine, N(p-tolyl) glycine, N-phenylalanine, sarkosine, N-laurylsarkosine, glycine, N,N-dimethylglycine, 3(N-phenyl) amino propionic acid, 3(N-p-tolyl) amino propionic acid, omega-amino fatty acids, N-substituted-omega-amino fatty acids, the addition reaction product of N-phenyl glycine and glycidyl reagents, the reaction product of N(substituted phenyl) glycine and glycidyl reagents, and other amino acids; is applied to the surface. Third, a solution of PMDM is applied to the surface.
