Microleakage of a Consolidted Silver Direct Filling Material



F Eichmiller, Anthony A. Giuseppetti, Kathleen M. Hoffman, D R. Brajdic, V Miksch, J A. Delorey-Lytle


Microleakage of an experimental direct filling materisl comprised of a chemically precipitated silver powder that had been surface treated with a dilute acid to promote cold welding upon consolidation was evaluated. Microleakage was compared to both dispersed-phase and spherical amalgam by use of an in vitro gas-diffusion method and in class 5 restorations placed in extracted human teeth. The effect of two cavity varnishes and two dentin adhesives as cavity liners on microleakage was also evaluated uisng extracted teeth. Microleakage of silver powder consolidated with dental instruments was less than that found with dental amalgam. The use of copal or polyamide cavity varnish resulted in the lowest combination of microleakage on dentin and enamel magrins.
