Objective: In the present study, three tooth colored, commercially available provisional restorative materials (Protemp 4, Cool Temp, Luxatemp Fluorescence) were chosen to test and compare the flexural strength and elastic modulus.

Materials and Methods: 30 specimens (with a change in thickness of 0.5mmin every 10) were fabricated for each material and stored in artificial saliva in separate plastic jars for 14 days. They were further tested for flexural strength by three-point bending test under a universal testing machine.

Results: The results obtained were statistically compared and it was found that the highest values of flexural strength and elastic modulus were exhibited by Protemp 4.

Conclusion: The present study concluded that Protemp 4 by 3M ESPE showed the highest flexural strength and elastic modulus; Cool Temp by Coltene showed the least flexural strength and Luxatemp Fluorescence showed the least elastic modulus amongst the three.
