We examined the effect of surface roughness of metal core on the bonding strength with different luting agents. In comparison for luting agents, MMA-type resin cement indicated much higher bonding strength than resin modified glass ionomer cement. Although difference in surface roughness of Ag-In alloys was not influenced on adhesion with MMA-type resin cement, resin modified glass ionomer cement was affected. Fracture mode of the adhesion with MMA-type resin cement were observed on the cohesive failure of resin cement. Therefore, the surface roughness of Ag-In and Ag-Pd-Cu-Au alloys does not influence the bonding strength with MMA-type resin cement.
