Abstract
This study investigated the effect of porcelain primer on bonding of coomposite resin to porcelain surface. In order to test the bond strength between porcelain and composite resin, porcelain cylinders were embedded in acrylic resin, and polished with 240grit silicone caqrbide paper. The specimens were divided into twelve groups. All specimens were treated with three porcelain primers and bonded with five composite resins. All test groups were stored in 37¡Édistilled water for 48hours. Shear bond strengths were for 48hours. Shear bond strengths were measured with Instron(Model 4201) at a cross-head speed of 1mm/min. @ES The obtained results were as follows: @EN 1. Scotchprime/Silux II group and BISCO Porcelain Primer/Bisfill group showed significant higher bond strengths than Clearfil Porcelain Primer/Photo Clearfil Bright group(p<0.05). And there was no significant differences in bond strengths between Scotchprime/Silux II group and BISCO Porcelain Primer/Bisfill group(p>0.05). 2. When composite resins were used with Scotchprime, the bond strengths were decreased Silux II(16.68¡¾3.35MPa). Bisfil(16.23¡¾4.54MPa). Poly-Fill(14.74¡¾4.08MPa), Photo Claearfil Bright(13.75¡¾2.89MPa) and Pekalux(14.74¡¾4.08MPa) in order, but there was no statistical significance(p<0.05). 3. When composite resins were used BISCO Porcelain Primer, the bond strength were decreased Bisfil(16.17¡¾1.60MPa), Silux II(12.13¡¾2.37MPa), Poly-Fill(10.78¡¾1.99MPa), Photo Clearfil Bright (9.91¡¾4.59MPa) and Pekalux(7.36¡¾2.16MPa) in order, but there was no statistical significance(p>0.05). 4. Silux II, Photo Clearfil Bright and Poly-Fill used with Scotchprime showed significant higher bond strengths than BISCO Porcelain Primer(P<0.05).
