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":"\u672c\u7814\u7a76\u306f\u6f0f\u6597\u72b6\u306b\u7aa9\u6d1e\u5f62\u6210\u3055\u308c\u305f\u6b6f\u6839\u306e\u4fee\u5fa9\u7269\u306b\u304a\u3051\u308b\u7834\u640d\u5f37\u3055\u3068\u521d\u671f\u306e\u7834\u640d\u69d8\u5f0f\u306b\u3001\u30dd\u30b9\u30c8\u306e\u7a2e\u985e\u3068\u8377\u91cd\u6761\u4ef6\u304c\u53ca\u307c\u3059\u5f71\u97ff\u3092\u691c\u8a0e\u3057\u305f\u3002\u6f0f\u6597\u72b6\u306b\u6839\u7ba1\u5f62\u6210\u3057\u305f\u629c\u53bb\u4e0b\u984e\u5c0f\u81fc\u6b6f40\u6b6f\u3092\u7528\u3044\u300120\u6b6f\u306b\u306f\u30ac\u30e9\u30b9\u30d5\u30a1\u30a4\u30d0\u30fc\u30dd\u30b9\u30c8\u3068\u30b3\u30f3\u30dd\u30b8\u30c3\u30c8\u30ec\u30b8\u30f3\u30b3\u30a2
