Résumé
The present study was undertaken to evaluate the most suitable recent restorative material for extensively mutilated teeth. This study aims to evaluate and compare the fracture resistance of maxillary premolars with Class II mesio-occlusal distal (MOD) cavities restored with recent Ever X posterior, bulk-fill composite, and Estelite sigma quick composite systems. Sixty human maxillary premolars were selected. Fifteen intact teeth served as positive control (Group 1). MOD cavities were prepared in the remaining 45 teeth with standardized dimensions and were randomly divided into three experimental groups (Group 2, 3, and 4) ( Group 4 (1432.60 N) showed the highest mean fracture resistance followed by Group 3 (1326.20 N), Group 1 positive controls (1288.53 N), and Group 2 (946.66N), respectively. One-way analysis of variance (ANOVA) test revealed a statistically significant difference between all the groups ( Among the experimental groups, Estelite sigma quick composite showed the highest fracture resistance. Statistically, a significant difference was seen between all groups.

RESULTS
Group 4 (1432.60 N) showed the highest mean fracture resistance followed by Group 3 (1326.20 N), Group 1 positive controls (1288.53 N), and Group 2 (946.66N), respectively. One-way analysis of variance (ANOVA) test revealed a statistically significant difference between all the groups (
CONCLUSION
CONCLUSIONS
Among the experimental groups, Estelite sigma quick composite showed the highest fracture resistance. Statistically, a significant difference was seen between all groups.
