Abstract :Objective: This study aimed to evaluate the effect of bleaching discolored teeth after regenerative endodontic treatment on fracture resistance. Methods: Forty human maxillary incisors were selected for the study and were divided into four study groups insert ignore into journalissuearticles values(n=10);. Group 1 was called the positive control group, and no treatment was applied. In Group 2; root canals were enlarged to size 6 peezo reamer bur to mimic an immature tooth. The disinfection protocol was performed according to the regenerative endodontic treatment protocol of the American Association of Endodontists. 3 mm thick mineral trioxide aggregate insert ignore into journalissuearticles values(MTA); was placed at the cementoenamel margin and restored with a temporary restorative material. The samples in group 3 were restored with glass ionomer and composite resin. In Group 4 bleaching was applied with 35% hydrogen peroxide bleaching agent to the samples before restoration with glass ionomer and composite resin. Then each group was applied to the cervical fracture resistance test with a universal testing machine. The fracture resistance values were recorded in Newtons insert ignore into journalissuearticles values(N);, and the obtained data were analyzed statistically. Results: While the highest fracture strength was obtained in group 1 insert ignore into journalissuearticles values(1092 ±9.27N);, the lowest fracture resistance was observed in group 2 insert ignore into journalissuearticles values(493.8 ±7.60N);. The difference between all groups was statistically significant insert ignore into journalissuearticles values(p<0.05);. Conclusion: 35% hydrogen peroxide bleaching agent application after regenerative endodontic treatment reduces fracture resistance of the tooth.
