Evaluation of fracture resistance of teeth restored with composite
Shabir Ahmad Bhat

Background: Endodontically treated teeth are more prone to fracture than vital teeth. The present study was conducted to assess fracture resistance of teeth restored with composite resins. Materials & Methods: The present study was conducted on 60 non carious periodontically weak mandibular premolars. Teeth were divided into 3 groups. The specimens were mounted in an universal testing machine and subjected to an axial compression load applied parallel to the long axis of the tooth. Results: In group I, teeth were restored with direct composite resins. In group II, teeth were restored with indirect composite resins and group III teeth were control. Each group had 20 teeth. Fracture resistance of group I teeth was 1.42 KN, group II was 1.87 KN and group III was 1.92 KN. The difference was non- significant (P> 0.05). Conclusion: Authors found that both direct and indirect composite resins had equal fracture resistance.
Key words: Fracture, Composite resin, Vital.
