| Description |
Background: This in vitro study evaluated the effect of modified Carisolv gel on the shear bond strength of delay repaired light cure Helio Progress composite with Excite bond and Dyract≡eXtra compomer with Prime & Bond NT. Materials and Methods: Thirty specimens of Helio Progress composite and thirty specimens of Dyract≡eXtra compomer of (6mm diameter & 3mm depth) were aged for one week at 37 C°. The aged substrate surfaces were abraded by coarse Al2O3 Sof-Lex discs and subjected randomly to different surface treatments: Modified Carisolv gel, phosphoric acid gel (control) and combination of both, with two different bonding agents Excite bond with composite and Prime & Bond NT with compomer.Repair was done by using a standardized translucent plastic straw (3mm diameter & 6mm length) and light cured. All specimens were stored in deionized distilled water for 24 hours. Each specimen was subjected to a shear force at a crosshead speed of 0.5 mm/min using a universal testing machine until failure. ANOVA and student t-test were used to analyze the bond strength values. Results: All surface treatment methods showed highly significant difference compared to control (p0.05). Different bonding agents did not show a significant difference (p>0.05) in bond strength values. Conclusions: Different combinations of surface treatments and bonding agents affect shear bond strength differently. The highest shear bond strength values were achieved with modified Carisolv gel alone and combination of modified Carisolv gel and phosphoric acid gel, whereas the lowest values were obtained with phosphoric acid gel alone as a surface treatment agent. |
