Background: Fracture resistance of an endodontically treated tooth is less when compared with natural tooth as in root canal treated tooth. The present study was conducted to compare fracture resistance of teeth restored with different restorative materials. Materials & Methods: The present study was conducted on 60 non carious, single-canal human lower first premolars of both genders. Teeth were randomly divided into 4 groups of 15 teeth each. Group I was Control group (no alteration done). Group II teeth were restored with silver amalgam after endodontic therapy. Group III teeth were restored with posterior composite after endodontic therapy and group IV: teeth were restored with posterior GIC after endodontic therapy. Results: The mean fracture resistance (Newton) in group I was 1027, in group II was 858.2, in group III was 942.5 and in group IV was 639.2. The difference was significant (P< 0.05). Conclusion: Authors found that fracture resistance of composite was maximum followed by amalgam and GIC.
