Abstract
 
Background and aim: Using Stainless Steel Crowns (SSC) for Early Childhood Caries usually causes an unpleasant condition in the aesthetic of the patients. The aim of this study was to evaluate the effect of different surface treatments and bonding systems on shear bond strength of composite veneer to Stainless Steel Crown.
Materials and Methods: In this in vitro study, 120 SSC were divided into 6 groups according to the surface treatment method (without surface treatment, diamond bur or sandblast) and bonding agent (alloy primer+Clearfil SE Bond or G Premio Bond). Shear Bond Strength (SBS) of composite cylinder to SSC was measured. Data were analyzed using ANOVA and Tukey. P-value <0.05 was considered statistically significant.
Result: SBS with Alloy Primer+Clearfil SE Bond (37.53±9.13) was significantly higher than G Premio Bond ( 30.54± 12.34) (P-value <0.0001). Sandblast showed significantly higher SBS in comparison with two other groups (P-value <0.0001)
Conclusion: Based on the results of this study, sandblasting has the highest SBS in comparison with the other methods of surface treatment. In the absence of sandblast, the application of the Alloy Primer+ Claerfil SE Bond on the SSC surface will provide better bond to resin composite.
