Abstract
Background: The number of endodontic procedures has increased steadily in the past decade with highly predictable results. Therefore, restoration of teeth after endodontic treatment is becoming an integral part of the restorative practice in dentistry. When restoring an endodontically treated tooth, the first step is to assess the level of predictability involved in the restoration. Proper restoration of ET teeth begins with a good understanding of their physical and biomechanical properties, anatomy, and a sound knowledge of the endodontic, periodontal, restorative and occlusal principles. A thorough understanding of posts is necessary to make the right selection, as there are so many choices available. Finally, the choice of core material and the final restoration are important in achieving long-term clinical success.
Aim: To compare the fracture resistance of endodontically treated teeth restored with two different post-core systems.
Material and Method: The samples were split into two groups of 15 each and given root canal therapy on 30 maxillary incisors. For two experimental groups, post space preparation and tooth restoration utilizing glass fibre posts with composite cores and adhesive resin cement (Group A) and zirconia posts (Group B) respectively were carried out.. Using the universal testing apparatus, 0.5 mm/min of force was applied to each sample at 130 degrees until fracture was experienced. A statistical analysis of the data was done after measuring the fracture resistance.
Result: The least fracture resistance was found in Group A (Glass Fibre Post). Additionally statistically more significant than groups A and B was group B (Zirconia Post). According to the statistics that were found, the p value is significant (p< 0.05).
Conclusion: The load needed to fracture the custom-made zirconia post was higher than that of the glass fibre post, according to the study's limitations.
