[Emission microspectrometric study of the amalgam restoration-tooth interface]

Optical Emission Microspectroscopy was used to identify the corrosion products in the amalgam tooth interface with and without cavity varnish use in different times. The factor time determined new chemical elements in the older specimens. A major mercury concentration was found in the restoration interface which used cavity varnish, at the initial twenty-four hours. The first corrosion product had the tin in its composition, possibly from the degradation of 2 phase.
