Abstract: Packaging for orthodontic brackets having a pre-dispensed adhesive. The packaging comprises light opaque compartments, each compartment sized and dimensioned to contain a bracket, and having a reservoir such that adhesive applied to a portion of the bracket will remain in contact with that portion of the bracket, and will not be distributed over other portions of the bracket. Also, a formulation of adhesive adapted for pre-dispensing to orthodontic brackets, comprising Bis/GMA, EBADMA, and at least one polymerizing agent.

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; andacrylic 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.
