Adhesive Bonding of Various Materials to Hard Tooth Tissues. IV. Bonding to Dentin, Enamel, and Fluorapatite Improved by the Use of a Surface-active Comonomer.

This article discusses the results of a research study conducted to determine the strength of the adhesive bond between a dental acrylic resin and dentin, dental enamel, and fluorapatite. The study finds the average tensile strength of the bond to be 77.4, 54, and 77.4 kilograms per centimeter squared (kg/cm²) for the respective surfaces when treated with a combination of N-phenylglycine and glycidyl methacrylate (NPG-GMA).
