Background and objectives: To evaluate and compare the shear bond strength of fifth (total etch) generation, sixth (two-step, self etch adhesive) generation and seventh (one step, self etch adhesive) generation dentin bonding agents. Methodology: Group A(control group), B(control group), and C(experimental group) were made. In all the groups, except group- A, endodontic access cavities were prepared. The apical preparation was finished with F1 and F2 Protaper universal files followed by obturation. Excess GP coronal to the orifices was removed and condensed using heated hand pluggers. Standardized Class 2 MOD cavities were prepared for all groups except for the group A. After cavity preparation, all the teeth of the experimental group were then considered for the final coronal restorations. Results: The mean Shear Bond Strength obtained by 5th generation (group C) is highest, followed by 6th generation (group D) and 7th generation (group E). Conclusion: this study shows that the easier to use adhesive systems are inferior to multi-step adhesive systems. [Rijhwani A, Natl J Integr Res Med, 2019; 10(1):6-10]
