The Effect of Resin Coating Technique on Shear Bond Strength

The purpose of this study was to investigate the shear bond strength of metal discs luted to dentine using Resin Coating Technique. In this study the adhesives used were dentine bonding agents, namely, Clearfil SE Bond and Syntac Sprint which were applied one week prior to cementation of Cobalt Chromium (Co-Cr) alloy discs to determine if there was any increase in the bond strengths when later luted using Panavia F and Variolink II. Thus there were four test groups with twelve teeth in each group i.e. Group I: Panavia F, Group II: Clearfil SE Bond/Panavia F, Group III: Variolink II and Group IV: Syntac Sprint/Variolink II. The mean shear bond strengths for the four test groups were recorded and the data were compared. It was found that the bond strengths increased significantly with the coating of the dentine bonding agents.
