ABSTRACT
Objective:
To evaluate the effects of resistance of bonded amalgam restorations to fracture after treatment.Methods:
Fifty healthy extracted maxillary teeth were selected,ten of them as control.The remainder were prepared a mesial occlusal distal(MOD) cavity.All of the teeth were then divided into five groups 1st group control;2nd group direct restoration;3rd group Luting;4th group GC Fuji Ⅱ;5th group RelyX ARC.All specimens were placed in a 37 degree centigrade humidity chamber for 72 h.The samples were thermocycled for 2 500 cycles at a temperature of 5 ℃ and 55 ℃.The samples use fatigue testing and observe by scanning electron microscope.Results:
The preparation and restoration groups required significantly less force to fracture than the control group.The group with glass-ionomer cement bonding and composite resin bonding showed no significantly fracture resistance.Conclusion:
Bonded amalgam restoration is a effective technique.At the same time glass-ionomer cement bonding and composite resin bonding shows no significantly fracture resistance.
