Objectives- This study evaluated and compared the fracture resistance of different restorative materials as comparison to sound teeth. Methods and Materials- 75 extracted teeth were taken. Group A (n=15) was sound teeth followed by access opening, biomechanical preparation and obturation in other groups (Group B, C, D, E) followed by post endo-restoration with Ever X Posterior, Sonic Fill, Tetric N Ceram bulk fill and Beautifil flow were used. The fracture resistance was evaluated with the help of Instron machine. The fracture resistance of groups were compared by one factor analysis of variance and the significance of mean difference between the groups was done by Tukey’s HSD post hoc test after ascertaining normality by Shapiro-Wilk’s test and homogeneity of variance between groups by Levene’s test. P<0.05 was statistically significant. Results-Tukey’s test showed significantly different and higher fracture resistance of Group A and Group B as comparison to other groups. Conclusion- Within the limitations of thisstudy evaluated and compared to determine fracture resistance and comparison of Group A, B,C,D and E it can be concluded fiber reinforced (Ever X Posterior, Group B) composite could be considered as an alternative to crown coverage, considering the insignificant difference in the values of fracture resistance when compared to natural tooth. Keywords- Fracture resistance, Ever X Posterior, Beautifil flow, Sonic fill and Tetric N Ceram bulk fill, Instron machine.
