Abstract

An in-vitro evaluation was done to compare shear bond strength of four self etching primer adhesives to dentin. 75 human extracted molar teeth were selected. The occlusal surface of these teeth was ground to remove coronal enamel and expose dentin. The dentinal surface of each tooth was then abraded using series of silicon carbide (320, 400, 600 grit) abrasive paper. Teeth were divided into 5 groups of 15 teeth each and composite post were then built on the bonded surfaces using Z-100 hybrid composite. The teeth were then fractured applying shearing load through universal testing machine. Shear strength values were in the range of 15.96 to 22.64 Mpa. Clearfil S3 gave highest mean shear bond strength whereasAdhe SE gave lowest value of shear strength. Based on this study it could be concluded that contemporary self etching primer adhesives bond successfully to dentin and also their bonding ability seems to be comparable to conventional total etch system.
