Aim: The aim of this study was to evaluate the shear bond strength of glass ionomer cement (GIC) with e-mineral trioxide aggregate (MTA) and Biodentine when placed immediately and after initial set. Materials and Methodology: Forty acrylic blocks with 2-mm height and 5-mm diameter central holes were prepared and randomly divided into two equal groups (n = 20). Group A (n = 20) and Group B (n = 20) were filled with E-MTA and Biodentine, respectively. These groups (n = 20) were further divided into two subgroups each; subgroup A1 (n = 10) and A2 (n = 10) were the placement of GIC immediately over freshly mixed e-MTA and after initial set e-MTA, respectively, subgroup B1 (n = 10) and B2 (n = 10) were the placement of GIC immediately over freshly mixed Biodentine and after initial set Biodentine, respectively. All the samples were later subjected to UTM for shear bond strength test. Results: The highest shear bond strength was recorded with subgroup B1 were the placement of GIC immediately over freshly mixed Biodentine, i. e., (18.72 MPa) and lowest with subgroup A2 placement of GIC after initial set MTA (5.96MPa). The shear bond strength of GIC condensed over freshly mixed e-MTA (subgroup A1) shows higher mean value then after initial set MTA (subgroup A2); however, SBS was highest in the placement of GIC immediately over freshly mixed Biodentine (subgroup B1). Conclusion: Within the limitation of this in vitro study, it can be concluded that freshly mixed Biodentine can be restored immediately with GIC.
