A method for bonding to dentin and enamel.

In vitro tensile bond strengths of about 1 ton per square inch between composites and dentin and enamel were obtained by applying a 5.3% solution of ferric oxalate to the tooth surface, followed by water and air cleaning; by applying a 10% solution of NTG-GMA, followed by cleansing with solvent and air; by applying a 5% solution of PMDM, followed by air to remove the solvent; and by placing the freshly mixed composite against the treated surface. If this breakthrough in the laboratory leads to sufficiently durable adhesion in clinical practice, the conservation of retention-form dentin could increase patient comfort, reduce treatment time and cost, and lessen fatigue for dentists.

A silver staining technique for investigating wear of restorative dental composites.

A silver staining technique was developed to demonstrate microdefects in dental restorative composites. Fine silver particles were preferentially introduced into the damaged region to provide optical contrast between the damaged and the undamaged regions. The amount of silver deposition determined with an electron probe microanalyzer, provided an indication of the extent of damage within the dental composites. Examples to demonstrate this technique were given with one clinically worn dental composite restoration and one in vitro worn composite sample.
