Comparison of fracture resistance of endodontically treated teeth restored with two different fiber posts

Background: The aim of this study was to determine and compare the fracture resistance of endodontically treated teeth restored with two different glass fiber posts. Materials and methods: Thirty extracted intact human premolar teeth were selected for the study. All the teeth were decoronated maintaining root length of 15mm from apex. Root canals were enlarged using protaper rotary file. Obturated with gutta-percha using AH 26sealer, specimens were divided into 3 groups (n-10). In group1 Ever Stick posts was luted into the root canals using dual cure resin cement variolink II, in group2 Hi-rem posts were luted into the root canals, group 3 did not receive any posts. In group 1 and group 2 gutta-percha was removed, and post space was prepared using peso reamers. Fracture loading was accomplished using an universal testing machine at a cross head speed of 1mm/min in compression mode. Results: Group3 showed highest mean fracture resistance value (795 N), followed by group 1 (Ever Stick post) with mean value (715.40 N) and group2 (Hi-rem) with mean value (476N). Conclusion: Teeth restored with Ever Stick post has better fracture resistance value than Hi-rem posts.
