Microleakage evaluation of bonded amalgam restorations: Confocal microscopy versus radioisotope

Tangsgoolwatana/Cochran/Moore/Li

PMID: 9477897

The purpose of this study was to compare the degree and pathway of microleakage in bonded amalgam restorations utilizing fluorescent dyes with scanning laser confocal microscopy and 45Ca radioisotope with autoradiographs. Mesial slot preparations with enamel cervical margins and distal preparations with dentin margins were prepared in extracted human molars. Four liners, Copalite (control), All-Bond 2/Resinomer, Amalcoden, and Panavia 21, were used. Teeth were restored with Dispoersalloy or Tytin. After thermocycling, 7 days’ storage, and staining, the degree of microleakage was measured on an ordinal scale, Dental adhesive liners minimized microleakage; the ranking was, from most to least effective, All-Bond 2, Panavia 21, and Amalcoden. The control exhibited the greatest microleakage. Microleakage occurred most frequently at the liner-tooth interface. No significant difference was observed between amalgams. The high corerlation between the results of the fluorescent and radioisotope studies indicated that these two microleakage tests can be directly compared.
