Effects of surface treatments on the bond strength of glass hybrid restorative system repaired with hybrid composite resin

Abstract

Aim: To assess the bonding strength of the Equia Forte resin modified glass ionomer cement to the hybrid composite material by applying different surface treatments.
 Methodology: 140 samples as 70 Equia Forte and 70 G-eanial composites were produced as 8 mm diameter 3 mm high cylindrical standardized samples. The samples were divided into 7 groups to treat surfaces. G-eanial composite resins as 4 mm diameter 3 mm high was placed onto the samples and polymerized. Then 1000 thermal cycle was applied and samples were mounted in the universal testing machine. Obtained bond strength values were recorded as Newton. One way Anova and Scheffe post hoc tests were performed for statistics.
 Results: In the G-aenial group, the highest bond strength was obtained with laser-bond method (N=17.71, P<0.05) and the lowest bonding strength was obtained with only laser-treated method (N=3.45, P<0.05). In the Equia group, the highest bond strength was obtained with air abrasion-bond method (N=9.29, P<0.05) and the lowest bonding strength was obtained with only laser-treated method (N=0.00, P<0.05).
 Conclusion: The fact that sufficient bond strength could not be reached by any surface treatment in Equia Forte may suggest that replacing the Equia Forte instead of repairs may be a better choice.

A Comparative Study of the Repair Bond Strength of New Self-Adhesive Restorative Materials With a Resin Composite Material

“…These studies may provide some insight when evaluating the results of the present study. In a study to evaluate the RBS of resin composite and GHR material (Equia Forte Fil) with resin composite using the SBS test method, various surface treatment methods were tested [ 28 ]. For all surface treatment methods, the RBS of the resin composite was higher than that of the GHR.…”
