Purpose: The present in vitro study was conducted to evaluate and compare the hardness of four commercially available provisional restorative materials. Materials and Methods: The groups in the study were Protemp 4 group, Integrity group, Systemp C and B group, and Structure 2SC group ten specimens of dimensions 64 mm × 3.5 mm × 12.3 mm × 65 mm × 13.5 mm of each material was made. Moreover, a total of forty specimens were used in the study and were tested for micro hardness and the values obtained were evaluated. One-way analysis of variance was applied to the data, and post hoc test was carried out for intercomparison between groups. Results: The findings showed that mean hardness value of Protemp 4 which had the highest value of 65.990 Vickers hardness number (VHN) followed by integrity 60.300 VHN followed by 57.210 VHN in Structure 2SC and least of 56.520 VHN in System C and B group and it was found to be statistically significant. The post hoc test revealed there was evident between Voco (Structure 2SC) and Systemp C and B materials; there was no statistical difference in mean hardness of the material in comparison with Protemp 4 and Integrity. Conclusion: Protemp 4 showed the highest hardness followed by integrity, Structure 2SC and Systemp C and B.
