Abstract

Immature permanent teeth with thin dentinal walls are highly prone to fracture, creating a major challenge in restorative management. Therefore, it is of interest to evaluate the fracture resistance of simulated immature teeth restored using different reinforcement modalities. Forty extracted single-rooted human canines were standardized, simulated as immature teeth, and allocated into five groups: MTA–Gutta percha, MTA–MTA, MTA–Biodentine, MTA–Glass fiber post, and positive control, followed by fracture testing in a Universal Testing Machine. The MTA–Glass fiber post group demonstrated the highest fracture resistance, while the unfilled control group showed the lowest, with significant differences between the control and most reinforced groups. Overall, MTA and Biodentine provided reinforcement, but the combination of apical MTA and a glass fiber post yielded the greatest improvement in fracture resistance.
