Abstract
The novel system for the bonding of dental filling composites and orthodontic adhesives to tooth enamel wherein the enamel is treated with a 2.5%-15% aqueous solution of a strong mineral acid or organic acid. The enamel is rinsed with water and thoroughly dried. A curable hydrophilic monomer primer is placed upon the enamel, said enamel primer being selected from the group consisting of esters having the generic formula: ##STR1## wherein R is H or CH.sub.3 and n is 1-8; esters of the general formula: ##STR2## wherein R=H or CH.sub.3 and n is 2-8; the mono and dimethacrylates or acrylates of glycerol; and PA0 acrylic or methacrylic acid. A methacrylate or acrylate based orthodontic adhesive or dental composite is cured on the surface of the primed enamel to give a material strongly bonded to the enamel surface.
