| Abstract | ||
| Aims: To evaluate and compare the fracture resistance of maxillary central incisors received EverStick adaptable glass fiber reinforced composite posts and prefabricated glass fiber Luxa post and to determine the mode of failure. Materials and Methods: Thirty extracted human permanent maxillary central incisor were decoronated, instrumented, and obturated. Post space was prepared in each root, randomly divided into 3 groups (n=10). Group (A): Control group; the roots remained without post space preparation. Group (B): The roots prepared to receive prefabricated translucent glass fiber posts (Luxa post). Group (C): The roots prepared to receive adaptable EverStick fiber reinforced composite post. After core built up, the specimens were thermocycled, mounted in a customized metal ring and fracture resistance was tested in a Universal Testing Machine. Data collected were analyzed statistically and the mode of failures was analyzed under stereomicroscope. Results: Statistical analysis revealed highly significant difference at p≤ 0.001. Group (C) showed the highest mean of fracture resistance followed by Group (B). While Group (A) the control group show the lowest mean of fracture resistance. Fracture pattern indicated that specimens in Group: C represent 100 % favorable failure, followed by group: B which represent 80 % favorable failure, while the control group showed 80 % unfavorable failure. Conclusions: EverStick adaptable glass fiber reinforced composite post showed significantly more predictable fracture resistance than prefabricated glass fiber Luxa post. | ||
