Abstract

Aim: The aim of this study is to comparatively evaluate the flexural strength of two commercially available bulk fill composites (SDR Flow+ and ColteneFill up)
Materials and methods: Ten bar shaped specimens were fabricated for each material (SDR Flow+ and Coltene Fill up) measuring 25 x 2 x 2 mm. All the specimens were subjected to thermocycling for 500 cycles at 5-50 degree celsius temperature with a 30 second dwell time at each temperature. All the specimens were loaded until fracture in a universal testing machine (INSTRON) and the values obtained were tabulated and statistically analyzed using Mann Whitney U test.
Results: The SDR group showed a higher mean flexural strength (42.50 MPa) than Coletene Fill up and this was statistically significant (p<0.05).
Conclusion: This study concluded that SDR Flow has a higher flexural strength than Fill up composite.
