To evaluate and compare the shear bond strength of GC fuji IX, Equia forte and secure Core Z to TheraCal LC. Methodology: A total of 30 acrylic blocks, each containing a cylindrical hole in the centre with a depth of 2mm and an internal diameter of 5mm, was prepared from self-cure acrylic resin. These 30 samples were randomly divided into three groups and restored viz Group A – TheraCal LC+ GC fuji IX, Group B – TheraCal LC + Equia Forte, Group C – TheraCal LC + Secure Core Z. All the specimens were stored in artificial saliva at 37°C for 24 hours before testing. The statistical tests used for the analysis of the result were: One way ANOVA, Tukey Multiple Comparison Test and Chi square test. The software used in the analysis were SPSS 24.0 and Graph Pad Prism 7.0 version and p<0.05 is considered as level of significance. Results: Group B (TheraCal LC + Equia Forte) showed highest shear bond strength followed by Group C (TheraCal LC + Secure Core Z) while Group A (TheraCal LC + GC Fuji IX) showed lowest shear bond strength. Conclusion: Equia Forte can be the restorative material of choice when TheraCal LC is used as base materials for better clinical efficacy.
