Abstract

Introduction: Endodontic ally treated teeth are weaker than intact teeth. Use of fiber-reinforced COMPOSITE RESIN posts in the treatment of these teeth can result in an integrated post-and-core complex because of the similarity of physic-mechanical properties of these posts to dentin. The aim of this study was to evaluate fracture resistance of teeth restored with three different types of glass fiber posts.Materials and Methods: Thirty extracted human upper central incisor teeth, which were similar in size, were selected and divided into three groups (n=10). In all the groups the crowns were sectioned 2 mm above the CEJ and endodontic treatment was carried out. Then HtCo, Anthogyr, Sevenska, and posts were cemented with Panavia cement in groups 1, 2 and 3, respectively, and restored with COMPOSITE RESIN. Fracture resistance of the samples was measured in a universal testing machine. Data were analyzed with ANOVA (a=0.05).Results: The means of fracture resistance values in HtCo (1), Antthogyre (2) and Sevenska (3) groups were 564.74±213.59, 629.12±390.33 and 779.84±282.59 N, respectively, with no significant differences between the groups (p value=0.285).Conclusion: Restorations carried out with Iranian fiber glass post (HtCo) exhibited fracture resistance similar to two other imported posts.
