ABSTRACT
The purpose of the present work was to study the effect of time ofcondensation and corrosion upon the edge strength of some amalgam alloys. Theangle of amalgam margins for all the samples has measured 70C and it wassubjected to a load of 500 gm. Amalgam condensation was made at 1, 2, 4 and 5min. after the end of trituration. Corrosion of amalgam samples was done bystoring the samples in 0.01 M lactic acid buffered with NaCl 0.02% adjusted topH 4. For the corroded samples, it was found that conventional amalgam showeda severe deterioration of the edge strength. While, for the non-gamma II, therewas a decrease in edge strength, but not statistically significant. For allthe investigated amalgam alloys, it was found that a triturated mix when kept5 min in air before condensation showed a marked reduction in the edgestrength
