title: The in vitro measurement of amalgam corrosion rates by the polarization resistance technique.
abstract: Measurement of the corrosion rates of three distinctive amalgam alloys (lathe-cut, spherical and dispersed-phase) when immersed in three different electrolytes, including saliva, is reported. The results indicate that the dispersed phase alloy amalgam exhibits a lower corrosion rate than a conventional lathe-cut alloy amalgam but is somewhat inferior to a spherical alloy amalgam.
