ABSTRACT

Introduction: Self-etch approach either two-or one-step adhesives are more user-friendly due to the time-saving and simplified procedure. The application of self-etch adhesives on GI or RMGI improve the bond strength to composite in comparison with total etch adhesives. Not many studies conducted to test whether pre curing or co-curing technique is better for conservative restorations. This study was done to evaluate shear bond strength of Resin modified glass ionomer cement to composite resin, using different adhesive systems with different curing techniques. Material and Methods: A total of 60 acrylic moulds (20mm × 20mm × 25mm) were prepared and in that hole was created (6mm × 6mm × 2mm). Resin modified glass ionomer cement was filled in 2mm height of acrylic moulds and kept uncured. The surface of Resin modified glass ionomer cements were softened by hand instrument and divided into two groups of 30 – Group A (Pre curing) and Group B (Co-curing) technique in each were sub divided into three subgroups of 10 according to adhesive systems (total –etch, two-step self-etch, one-step self- etch) were applied. Results: Group A2 (Two step self) had statistical significantly higher shear bond strength (p<0.05) as compared to subgroup A1 (Total Etch) and subgroup A3 (One step self) in both Group A (Pre curing) and Group B (Co-curing). Shear bond strength was statistical significantly higher in Co-curing groups as compared to Pre-curing groups in self-etch adhesive systems. Conclusion: This study concluded that shear bond strength between resin modified glass ionomer and composite resin was increased with the application of co-curing technique and self-etch adhesive system.

Keywords: Adhesive system, Curing technique, resin modified Glass ionomer cement, shear bond strength.
