Fracture resistance of endodontically treated teeth, restored with two post-core systems in different post space diameters (in vitro study).

Background: Fracture resistance of post-core restoration depends on the design of the post, post diameter, post length, the type of adhesive cement used along with material of the core. Despite the different studies concerning the effect of post space diameter on the fracture resistance of endodontically treated teeth, more information regarding fracture resistance and the effect of different post space systems/materials and diameters is required.

Aim Of The Study: This study aimed to evaluate fracture resistance of endodontically treated teeth, restored with two post-core systems in different post space diameters.
