Effects of a refrigerated amalgam bonding system on fracture resistance.
This in vitro study evaluated the effectiveness of using an amalgam bonding system at refrigerated temperature to regain fracture resistance in molars with large mesial-occlusal-distal restorations. Nineteen pairs of homologous contralateral pairs of third molars were used, with control teeth remaining intact. Although the bonded amalgam group developed 81% of the fracture strength values of the intact teeth, the intact teeth were found to have significantly higher fracture strength values (p = 0.0326, paired t-test).
