This in vitro study compared the tensile bond strength of gold and porcelain inlays to extracted molars in stanardized cavities. Three cements were used: zinc phosphate, glass-ionomer, and resin composite cement. The inlays were cemented using zinc phosphate or glass-ionomer cement, and the porcelain inlays were luted using resin composite or glass-ionomer cement. Surface treatments included, for gold inlays, either no treatment (zinc phosphate cement) or airborne particle abraded and tinplated (glass ionomer cement) or etched and silane-treated (resin composite cement). Statistical analysis was performed using the Weibull distribution. Results whowed no significant differences between gold inlays cemented using zinc phosphate or glass-ionomer cements. The bonded porcelain inlays (resin composite cement) showed tensile bond strengths two to three times higher than those obtained for cemented gold inlays.
