Objective:To compare the flexural and compressive strength of Nano hybrid versus conventional hybrid composite material.
Material & Methods:A total of 64 specimens were made (half from conventional hybrid composite and half from Nano hybrid).Thirty-twowere tested for compressive strength and 32 for flexural strength using universal testing machine. Two samples independent t test was used for comparison.
Results:The mean compressive strength of conventional hybrid composite was 260.1±36.6 MPa while for Nano hybrid composite it was 186.4±37.0 MPa and the difference was very highly statistically significant (p<0.001). Similarly, the mean flexural strength of conventional hybrid composite was 121.5±20.0MPa and for Nano hybrid was 91.6±11.6 Mpa with very highly statistical difference (p<0.001).
Conclusion: Conventional hybrid composite have better mechanical properties than Nano hybrid composite restorative material.
