| Abstract | ||
| The aim of this in vitro study is to evaluate the fracture resistance of pre-molars with three surface amalgam restor-ations. Fifty premolars were used, and divided into five groups. The teeth in group one remains intact whereas the teeth in the second group prepared and not restored. The teeth in the third group prepared and restored with amalgam only. In groups four and five, the amalgam res-torations were lined with All–Bond 2 and Scotchbond Multi Purpose Plus respec-tively. After thermocycling, the teeth were tested under universal compression ma-chine at a crosshead speed 5 mm/minute. Data were analyzed using one way Ana-lysis of Variance and Duncan’s Multiple Range Test. The results of this study ind-icates that both Scotchbond Multi Purpose Plus and All–Bond 2 increase the fracture resistance as compared to the control groups (groups two and three). The results of this study also show no significant difference between the two bonding agents regarding teeth fracture resistance. | ||
