Materials and methods : Flared post holes were prepared in 40 sound human lower premolar roots. Twenty roots received glass fiber posts with resin core (fiber specimens) and 20 received cast post-and-core (cast specimens). After cementation with resin cement, in 10 fiber and 10 cast specimens, a quasi-static bending test was performed by an Instron-type testing machine. In the other specimens, before the bending test, a bucco-lingual load was applied for 900,000 cycles using a lever-type device. Failure resistance and primary failure mode in relation with post type and loading condition were statistically analyzed (significance level: 0.05). Results : After cyclic loading, all specimens were intact; therefore, they underwent the bending test. Failure resistance showed a significant difference only for the post type (p = 0.002) (two-way ANOVA). In the presence of cyclic loading, the post type significantly influenced failure resistance (p = 0.010), whereas in its absence, it showed only a tendency to influence failure resistance (p = 0.054) (Tukey test). In the cycled specimens, significantly fewer root fractures and more frequent debonding without root fracture were found in the fiber than in the cast specimens (p = 0.02) (Fisher\u2019s exact test). Conclusions : Rather than cast post-and-cores, the use of glass fiber-reinforced posts and resin core for the restoration of flared canal teeth may prevent root fracture, but debonding may occur under high loads.", "subitem_description_type": "Abstract"}, {"subitem_description":
