The Relationship between the Shear and Tensile Bond Strength and the Type of Adhesive Material for Bonding Orthodontic Brackets: Comparative Study

The purpose of this study was to evaluate the shear and tensile bond strengths of orthodontic brackets bonded with self etching primer and resin-reinforced glass ionomer cement in comparison with light cured resin adhesive. The tested self-etching primer and adhesive systems produced bond strength values higher than that of the light cured resin adhesive whereas the resin-reinforced glass ionomer cement showed a significantly reduced bond strength . Clinically, the use of self-etching primer and adhesive systems is suitable for orthodontic bracket bonding.
