Abstract
Objective: The aim of this study was to compare the push-out bond strength (BS) of 2 different conventional fiber and glass fiber posts in the form of bundles by using 2 different resin cement and the fracture types formed accordingly. Material and Methods: Root canal treatment was applied to 48 extracted human premolars for the push-out test. The teeth were divided into 3 fiber post groups: Group 1: Biolight ST (conventional fiberpost), Group 2: RelyX (conventional fiberpost), Group 3: Biolight Plus (bundle post) according to the posts to be used for the push-out test. Each of the fiber post groups were divided into 2 subgroups according to adhesive cement [Core-X Flow, Build It FR] used in the cementation of posts (n=8). One mm sections were taken from the middle third of posts and the sections were subjected to a push-out test and the values were recorded. The samples were examined under a stereomicroscope and fracture types were determined. Results: No statistically significant difference was found between the groups according to the test results. When the fracture types were evaluated for all groups, there was no statistically significant difference in the result. Conclusion: The fiber post system in the form of bundles has similar properties with the conventional glass fiber post system in terms of BS.
