Abstract
The purpose of this study was to determine and evaluate the shear bond strength and fracture pattern of composite to stainless steel crowns(SSCs) using four different bonding systems: Single Bond 2, Clearfil SE Bond, One-step, Prime & Bond NT. And this in vitro study was to evaluate and compare the shear bond strength of direct composite resin(Clearfil AP-X) and indirect composite resin(Tescera) to sandblasted SSCs using two bonding agents, Clearfil SE Bond and One-Step. Clearfil SE Bond and One-step group provided higher bond strength than Single Bond 2 and Prime & Bond NT, but one-way ANOVA revealed no significant difference among the overall mean bond strengths for the four bonding systems(p>0.05). The mean shear bond strengths(MPa) and standard deviations were as follows: Clearfil SE bond-Tescera(11.98±1.53MPa); One-Step-Tescera(9.44±2.00MPa); Clearfil SE bond-Clearfil

AP-X(13.48±3.32MPa); One-Step-Clearfil AP-X(10.45±3.48MPa). No significant difference was found between direct and indirect composite resin groups. The bond strength values revealed that direct composite resin has slightly higher mean shear bond strength compared to indirect composite resin. Microscopic examination revealed adhesive and mixed bond failure. This study indicates that in certain situations, the operator might choose to bond direct composite resin to a fractured labial facing rather than replacing the SSC.
