Aim: The aim of the study was to compare the fracture resistance of roots obturated with mineral trioxide aggregate (MTA) obturation with post, MTA apical plug with Resilon obturation, MTA apical plug with gutta percha (GP) obturation, complete MTA obturation in teeth with wide open apex. Materials and Methods: Fifty freshly extracted human maxillary central incisors were selected. Teeth were divided into four experimental groups (n = 10) and one control group (n = 10). Fifty teeth were separated, and roots of each tooth were standardized to a length of 12 mm. Access opening was done and instrumented with ProTaper F2 passed beyond the apex. The canals were then irrigated with 17% ethylenediaminetetraacetic acid and 3% sodium hypochlorite. Calcium hydroxide was placed in the canals for 7 days. The specimens were then divided into five groups. Group I: Apical plug MTA with metal post, Group II: Apical plug MTA with Resilon, Group III Apical plug MTA with GP, Group IV: Complete MTA obturation, and Group V: Control group. Fracture strength was measured using Instron testing machine at a speed of 5 mm/min, and the data were statistically analyzed using ANOVA and t-test. Results: The roots reinforced with metallic post and MTA (Group 1) has the higher fracture strength when compared with other groups (P < 0.05). Conclusion: This Ferro-concrete reinforcement technique of MTA with the metallic post can be used in cases with wide open apex to increase the fracture resistance of tooth.
