Corrosion Penetration in Crevices of Dental Amalgam.

Abstract

A capillary-pore electrode with an optically transparent window for in situ viewing is used to screen three dental amalgams for their corrosion resistance. Results are in accord with more extensive clinical findings. Examinations by SEM and elemental microprobe show that a preferential corrosion of the poorly resistant tin-bearing phases involves dissolution of Sn with subsequent diffusion and deposition of an SnO hydrate preferentially on the gamma-one phase as a uniform, masking layer.
