Fracture Resistance of Endodontically Treated Teeth with Different Post Systems

Akriti Agrawal | Manju Choudhary [3]

Abstract: Endodontically treated teeth are known to present higher risk of biomechanical fracture than vital teeth. Endodontic posts or dowels are usually cemented into a prepared canal. They retain the core and equally distribute the forces of mastication to the supporting tooth structures. The study compares fracture resistance of root canal treated teeth with different types of post systems. Objectives: Comparison of Endodontically Treated Teeth with Different Post Systems Methodology: A total of 40 recently extracted mandibular premolars will be endodontically treated divided into 4 groups of 10 specimens, then restored with glass fiber, fiber, metal screw and cast metal posts. All posts were cemented. and specimens were secured in a universal load testing machine. Results: Highest fracture resistance was observed in cast post system. The mean value of group 1 was 286.3 N, followed by 303.5 N of group 2, 338.7 N of group 3, 450.3 N of group 4. Significant differences of fracture resistance were detected between group 1 and control (p < 0.001). Conclusion: The results of our study show that Custom cast posts though demonstrated highest fracture resistance, demonstrated higher catastrophic fractures whereas carbon fibre posts and glass fibre posts showed more number of repairable fractures.
