Aim: The aim of this study was to evaluate the incidence of root fracture of endodontically treated teeth restored with two different types of glass-fiber posts luted with glass-ionomer cement (GIC). Materials and Methods: Forty maxillary central incisors were sectioned at 1 mm of the cementoenamel junction and endodontically treated. The teeth were divided into two groups (n = 20) where Group I included teeth restored with Reforpost (No. 1, Angelus, Brazil) and Group II with Selfpost (Size 1, Medicept, UK). The posts were luted with GIC, and core built up was done using composite resin. The fracture strength was evaluated using a universal testing machine. The data obtained were tabulated and subjected to statistical analysis. Results: The comparison of the mean strength required (in Newtons) to fracture the teeth was higher in Group I that is Reforpost than Group II (Selfpost) implicating highly significant differences in their fracture resistance (P ≤ 0.001). Conclusion: The conclusion drawn was that Group I (Reforpost post) exhibited better resistance to fracture than that of Group II (Selfpost post).
