Background: The present study was conducted to compare four treatment modalities of fracture resistance of teeth undergoing post endodontic bleaching. Materials & Methods: The present study was conducted in the department of Endodontics on 50 human mandibular premolars with completely formed apices. Specimens were divided into 5 groups based on bleaching procedures. All the specimens were subjected to fracture resistance test using Universal Testing Machine. Results: Fracture resistance in group I was 950.4 N, in group II was 914.6 N, in group III was 1272.4 N, in group IV was 1240.6 N and in group V was 1598.2 N. The difference was significant (P< 0.05). Conclusion: Authors found that use of 10% sodium ascorbate antioxidant gel was effective in compensating for the decreased fracture resistance following combination bleaching. Key words: Bleaching, Fracture resistance, Sodium ascorbate.
