Abstract

A self-etching and self-adhesive dental composition is provided, comprising a polymerizable (meth)acrylate carboxylic acid/anhydride; a copolymerizable multi-functional (meth)acrylate resin; a copolymerizable diluent monomer; and a curing system. The composition has the advantage of not requiring a separate etching and bonding step.
