Shear bond strength of restorative particulate resin composite with a short fiber-reinforced resin composite substructure

Research output: Contribution to journalArticlepeer-review

Abstract

Objective: This study aimed to identify the shear bond strength of two different restorative particulate resin composites with a short fiber-reinforced resin composite (SFRC) substructure. Methods: Two restorative particulate resin composites, G-aenial PosteriorTM (Group A, 10 specimens) and Tetric N-Ceram™ (Group B, 10 specimens), were used as an upper layer of everX posteriorTM, an SFRC. A shear bond strength test was performed using a universal testing machine with a load of 100 kgf and a crosshead speed of 0.5 mm/min. The data were analyzed statistically using the independent samples t-test. Results: The mean shear bond strength values were found to be18.64±1.5 MPa (Group A) and 22.05±1.8 MPa (Group B). A significant difference in shear bond strength between the two groups was found. Conclusion: The shear bond strength value is higher in the Tetric N-CeramTM restorative particulate resin composite with SFRC as a substructure than the G-aenial PosteriorTM restorative particulate resin composite.
