Evaluation of fracture resistance of FRC posts, zirconia post and Parapost in endodontically-treated teeth

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.

“…Previous studies by Saritha et al, Kurthukoti et al and Shukla et al compared fracture resistance of zirconia posts and glass fiber posts of endodontically treated teeth. They proved that fracture resistance between tested groups was not significant ( P > 0.65) and zirconia and fiber-reinforced posts showed high fracture resistance values which came in accordance to the findings of the current study [ 37 , 39 , 45 ].…”

“…When the remaining tooth structure of endodontically treated teeth cannot provide sufficient support and retention for restoration; remaining less than 50% of tooth structure, post and core is beneficial. So the rehabilitation of pulpless teeth is crucial in order to restore them esthetically, functionally and structurally for a successful restorative outcome and prognosis [ 37 , 38 ].…”
