Aim To evaluate the fracture resistance of simulated immature teeth that had been backfilled using different materials after using B iodentine as the apical plug material. Design Seventy‐five single‐rooted teeth were divided into five groups ( n = 15). The 15 teeth in group 1 served as a negative control group and received no treatment. The remaining 60 teeth were instrumented to a #6 P eeso reamer to obtain a standard internal diameter of 1.5 mm. The apical 4 mm of 60 teeth was filled with B iodentine. The backfilling was then performed on each group as follows: group 2 – no backfilling (positive control), group 3 – gutta‐percha, group 4 – fiber post, and group 5 – B iodentine. Specimens were then subjected to fracture testing. The force required to fracture each specimen was recorded, and the data were statistically analyzed. Results The mean fracture values of groups 1 and 4 were significantly higher than groups 2, 3, and 5 ( P < 0.05). The values of groups 3 and 5 were significantly higher than group 2 ( P < 0.05). Conclusions The backfilling with fiber post after an apical B iodentine plug provided the highest fracture resistance among all experimental groups.
