چکیده
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 and divided into four groups (n=10). Group 1 was called positive control group, no applied. In 2; root canals enlarged size 6 peezo reamer bur mimic an immature tooth. The disinfection protocol performed according American Association Endodontists. 3 mm thick mineral trioxide aggregate (MTA) placed at cementoenamel margin restored with a temporary restorative material. samples in group glass ionomer composite resin. 4 applied 35% hydrogen peroxide agent before restoration Then each cervical resistance test universal testing machine. values recorded Newtons (N), obtained data analyzed statistically. Results: While highest strength (1092 ±9.27N), lowest observed 2 (493.8 ±7.60N). difference between all statistically significant (p<0.05). Conclusion: application reduces
