The aim of this study was to evaluate the fracture resistance of simulated immature teeth after internal bleaching. The teeth were assigned as follows ( n = 12/group); Group‐1: The pulp chamber was filled with ProRootMTA and bleached intracoronally with sodium perborate mixed with 37% carbamide peroxide gel; Group‐2: The pulp chamber was filled with ProRootMTA without bleaching; Group‐3: The pulp chamber was filled with Biodentine and bleached intracoronally as Group‐1; Group‐4: The pulp chamber was filled with Biodentine without bleaching; and Group‐5: Teeth received no intervention (control). The specimens were loaded vertically until root fracture occurred. The data were analysed with Kruskal–Wallis and Dunn tests. There was no significant difference between the fracture resistances of the experimental groups ( P > 0.05). However, all experimental groups had significantly lower fracture resistance than the control group ( P < 0.05). Neither the tested calcium silicate cements nor the bleaching procedures had a significant impact on fracture resistance values.
