Abstract
This study was designed to investigate the influence of two techniques used for restoring endodontically treated teeth on their fracture resistance.
The objectives were:
1-Evaluation of the fracture resistance of endodontically treated teeth restored with two different resin composite materials (Microhybrid light cured versus dual cure one).
2-Comparison of fracture resistance of endodontically treated teeth restored with fiber post and without fiber post.
