This study was performed on seuerntil-two freshly extracted first permanent mandibular molars. In half of the samples (thirty six) root canal treatment was done and access cavities were sealed with glass ionorner/ cement. In the other half cavities were prepared to a depth of 4 mm. Cavity designs used were class 1. class 11 arid tunnel preparation. In each group half of the samples were restored with composite and half of them with amalgam. Fracture resistance was calculated with the help of Instron Universal Tensile Testing machine. It was concluded that after endodontic treatment strength of the teeth to bear masticatory loads is reduced to almost half and composite can effectively reinforce as compared to amalgam.
