Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Oral and Dental Medicine - Department of Prothodontics Summary: Background: Many post systems are available to clinicians, yet no consensus exists about which one is better in restoring endodontically treated teeth. Purpose: This study evaluated the fracture resistance of weakened roots restored with custom . Results: Teeth restored with cast posts had the highest fracture resistance. Fiber-reinforced resin posts failed at a compressive force comparable to clinical conditions, but most failures were repairable. Thinner root dentin walls significantly decrease the fracture resistance of endodontically treated teeth. Conclusion: Fracture resistance and mode of failure in anterior teeth with flared canals varied according to the type of post used to support a crown.
