Aims and Objectives: The successful endodontic therapy is judged by ability of tooth to withstand masticatory forces. The present study focused on comparing the strength of restorative materials, i.e., compomer, ormocer, nanocomposite, and ACTIVA Bioactive after conditioning in dietary solvents. Materials and Methods: This in vitro study consisted of 26 specimens of each restorative material Compomer (F2000 3M ESPE), Nanocomposite (Filtek Z350XT), Ormocer (Admira VOCO), and ACTIVA Bioactive (Pulpdent). The I-shear–punch test was conducted with the help of custom-designed shear–punch apparatus in Universal Testing Machine in different dietary solvents. Results were statistically analyzed using IBM SPSS Statistics for Windows, Version 20.0. (IBM Corp., Armonk, NY) and using Tukey’s test and one-way analysis of variance test at P < 0.5. Results: Ormocer conditioned in heptanes had the highest mean shear–punch strength. ACTIVA Bioactive conditioned in distilled water showed the highest mean shear–punch strength. There was a significant difference in bond strength among all restorative materials (P < 0.05). Conclusion: Ormocer conditioned in heptane had significantly higher shear strength. ACTIVA Bioactive conditioned in distilled water had significantly increased shear strength. The nanofilled composite was significantly stronger than the Ormocer, ACTIVA Bioactive, and Compomer – a polyacid-modified composite.
