Since the advent of acid etching, composite resin technology has improved. 1 Composite resins are bonded mechanically to acid-etched enamel, relying on a large interlocking area between the two to form an effective bond. Bonding of composite resin to dentin is attained by chemical means, either to the organic or inorganic part of the dentin. Polymerization shrinkage, however, still plagues the longevity of direct resin restoration2, -~ Although the mechanical bond with enamel is sufficiently… CONTINUE READING
