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-modifiedglass ionomer cement to the hybrid composite material by applyingdifferent surface treatments.Methodology: 140 samples as 70 Equia Forte and 70 G-eanial compositeswere produced as 8 mm diameter 3 mm high cylindrical standardizedsamples. The samples were divided into 7 groups to treat surfaces. Geanial composite resins as 4 mm diameter 3 mm high was placed onto thesamples and polymerized. Then 1000 thermal cycle was applied andsamples were mounted in the universal testing machine. Obtained bondstrength values were recorded as Newton. One way Anova and Scheffe posthoc tests were performed for statistics.Results: In the G-aenial group, the highest bond strength was obtainedwith laser-bond method (N=17.71, P
