  • Title: Investigation of surface corrosion in amalgam.
    Author: Günday M, Gencoğlu N.
    Journal: J Nihon Univ Sch Dent; 1992 Sep; 34(3):178-82. PubMed ID: 1287146.
    Abstract:
    In this study, surface corrosion of carved and polished specimens of conventional and high-copper amalgams was investigated. The specimens were studied to detect surface corrosion after immersion in artificial saliva for 48 h or 1 year, and later investigated by SEM. Corrosion was greatest in 1-year-immersed carved conventional amalgam specimens. The surface was very rough with the contours of the particles visible and deep holes opening at the surface. High-copper amalgam specimens showed less corrosion than conventional amalgam specimens.
