The specimens were taken from each (amalgam alloy before and after homogenization heat treatment and amalgam with all additions) using different grades of emery papers (400, 600, 800, 1200, 1500, 2000, 2500), then polished by 3[micro]m diamond paste.
Similarly only one kind of bonding agent was used and only high copper amalgam alloy was used, other bonding agents or low copper amalgam alloy may act differently.
Further, since the 30% spherical amalgam alloy additive yielded the most significant improvements in terms of physico-chemical properties in the present study, the potential citotoxic effect of products from corrosion of amalgam particles should be further investigated.
(81) In 1987, the FDA labeled the two separate premixed components of dental amalgams, the amalgam alloy and the dental mercury, as Class II and Class I devices, respectively.
