[Mercury release from amalgam specimens].

Abstract

Over 7 days specimens of 5 gamma 2-free Amalgams were stored in KSCN-containing and KSCN-free lactic acid-salt solution. After 1, 4 and 7 days samples of the solution were analyzed for their mercury contents using inductively coupled plasma atom emission spectroscopy. In KSCN-containing solution the release of mercury was 45.4 micrograms, in KSCN-free solution it was 70.7 micrograms/50 mm2. KSCN, a part of natural saliva, has the effect of inhibiting corrosion.
