In Vitro Comparison of the flexural strength of 3 commercially available composite resin based restorative materials

Abstract

Objective:- The aim of this study is to comparatively evaluate the flexural strength of 3 commercially available bulk fill composites. Materials & Methods:- The study compared and evaluated the flexural strengths of three different types of dental restorative materials: Te-Econom Plus (manufactured by Ivoclar Vivadent AG, located in Liechtenstein), Titric-Power-Fill (manufactured by Ivoclar Vivadent AG, located in Liechtenstein) and Tetric N-Ceram Bulk Fill (manufactured by Ivoclar Vivadent AG, located in Liechtenstein). The flexural strength was assessed following the ISO (International Organization for Standardization) Standard 4049. To conduct the study, 10 specimens were fabricated for each material group. Statistical analysis was performed using one-way ANOVA with a Tukey post-hoc test to determine any significant differences among the groups (p < 0.05).Results:- The results of the study indicate that Group 1 showed the highest mean flexural strength value (143.40 ± 0.31 MPa), followed by Group 3 with a mean flexural strength value of 129.20 ± 0.39 MPa. Group 2 displayed the lowest mean flexural strength value of 120.70 ± 0.45 MPa.Conclusion:- Tetric Power fill composite exhibited notably higher flexural strength values in comparison to Tetric N-Ceram and Te Econom plus alternatives.
