Abstract

Introduction and Objectives: Root canal treated teeth are more prone to fracture and reconstruction of such teeth to achieve required strength, function and esthetics still remain a challenge. Therefore, this in vitro study was carried out in order to determine the mode of failure and compare the fracture resistance of endodontically treated teeth restored with GC everStick post and Easy post.
Materials and Method: 30 single rooted first mandibular premolars were endodontically treated. All the samples were randomly divided into 3 groups (n=10) according to the post system. (GC everStick post – Group I, Easy post - Group II –, Negative control - Group III). In all the samples, mesio-occluso-distal (mod) cavities were prepared and restored with composite restorative material (filtek z250xt). Fracture resistance was measured in a universal testing machine (Mecmesin, England) until fracture and the data was analyzed statistically.
Results: Group I showed highest mean fracture resistance (819.91N), followed by Group II (425.31N) and control group (204.82N). All the samples restored with GC everStick post showed repairable fracture whereas 60% samples restored with easy post showed repairable fracture.
Conclusion: This in vitro study concluded that everStick post could be a simple and efficient way to rehabilitate endodontically treated teeth.
