Abstract

Introduction: A material which is used as a base must have an adequate seal, be able to prevent leakage, and remain in place under dislodging forces, such as chewing pressure and also having adhesive properties to restorative materials and to the dentine. Hence, it is important to know the bond strength in clinical practice. Aim and objective: The aim and objective of this study was to evaluate the shear bond strength (SBS) of the glass ionomer cement (GIC) and resin composite with Biodentine as a base. Materials and methods: Acrylic blocks with a central hole measuring 2 mm in depth and 5 mm in diameter were prepared. A total of 30 samples were prepared, the holes were then filled with Biodentine and the samples were randomly divided into 3 subgroups consisting 10 specimens each: group I: methacrylate-based (MB) composite, group II: Fuji type II resin-modified GIC (RMGIC), and group III: Fuji type IX GIC. For the SBS test, each block was secured in a universal testing machine and the values were compared by using one-way analysis of variance. Results: Highest bond strength of 1.495 ± 0.05 MPa was observed in group I (i.e., MB composite), followed by group II with 1.139 ± 0.02 MPa (i.e., type II RMGIC), and the lowest bond strength of 0.80 ± 0.05 MPa observed in group III (i.e., Fuji IX GIC). Conclusion: The adhesion of Biodentine to MB composite surface appears to be greater compared to that of RMGIC and GIC.
