Materials and methods
Six fiber-reinforced groups (n = 10) were made with three different lengths (10, 15, 20 mm) with or without glass fiber in split mold. The specimens were early cured and then post-cured with a labolite unit, then specimens were subjected to three-point flexural test by a universal testing machine. Data were analyzed with ANOVA and LSD post-hoc test (p < 0.05).
Maximum fracture load of specimens increased with decreasing lengths (p < 0.001) and fiber-containing group showed significantly higher fracture load than fiberless groups (p < 0.001).
It was concluded that by increasing the span length, the maximum fracture load values (N) decreased incorporation of fiber results in higher fracture strength values.
