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 @entity10193 , MTA apical plug with gutta percha (GP) obturation, @entity1423 in @entity4500 with wide open apex. MATERIALS AND METHODS: Fifty freshly extracted @entity1 maxillary central incisors were selected. Teeth were divided into four experimental groups (n = 10) and one control group (n = 10). Fifty @entity4500 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% @entity1098 and 3% @entity8830 . @entity6086 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: @entity1423 , and Group V: Control group. @entity174 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.

Ferro-concrete reinforcement of endodontically treated XXXX with wide open apex.
