Abstract
Endodontically treated teeth are susceptible to fracture, making optimal post and luting material selection critical for long-term restoration. Therefore, it is of interest to compare the fracture resistance of glass fiber and Ribbond posts luted with dual-cure resin cement or flowable composite in 55 extracted single-rooted premolars. Following standardized endodontic treatment and core build-up, specimens underwent compressive loading in a universal testing machine, and fracture resistance values were statistically analyzed using one-way ANOVA and Tukey's post-hoc test (p < 0.05). All restored groups exhibited significantly greater fracture resistance than the control, with glass fiber posts luted using dual-cure resin cement showing the highest strength and Ribbond posts luted with flowable composite the lowest. Thus, data shows the both post type and luting material significantly affect fracture resistance; supporting glass fiber posts with dual-cure resin cement as that most effective restorative combination.
