Abstract
Objectives: To evaluate the fracture resistance efficacy of FRC posts and photo core, zirconia post and Parapost in endodontically treated teeth. Materials and Method: Thirty recently extracted mandibular first premolar teeth were randomly grouped in to 3 different groups with 10 samples in each group: FRC posts and photo core, zirconia post and Parapost. Fracture resistance in each group was estimated and compared. Results: The fracture resistance was 428.2, 432.1 and 232.5 for group I, II and III. The difference was statistically significant. The mean fracture resistance between group I to Group III and II with III was statistically significant (0.01). The fracture resistance between Group I and II was not significant (P>0.65). Conclusion: Authors found that zirconia and FRC posts exhibited higher fracture resistance as compared to paraposts.
