Electroetching of Dental Amalgam
Journal of Dental Research, 1974Application of the potentiostatic polarization technique to the metallographic etching of set dental amalgam is described. Etching studies of amalgam prepared from a lathe-cut, a spherical, and a silver-copper dispersed-phase amalgam alloy are reported. The γ2 phase in set dental amalgam can be characterized by this electrochemical technique.

Abstract: The mercury concentrations in blood (HgB) and urine (HgU) samples, and in exhaled air (HgAir) were measured in 147 individuals from an urban Norwegian population, using cold vapour atomic absorption spectrometry. The study aimed to estimate the mercury exposure from the dental restorations, by correlating the data to the presence of amalgam ...

This Critical Appraisal is a departure from our usual format. Usually, contributors review several articles about a specific topic. Instead, we have asked Dr. Osborne to review several topics related to a specific issue, the safety of dental amalgam. Despite the increasing use of tooth‐colored restorative materials, amalgam remains a widely used and ...

DENTAL amalgam is incorporated into about 80% of all dental restorations. It is prepared by grinding or triturating a silver–tin alloy (Ag3Sn, the γ phase) with mercury in the proportions 1 : 1 or 5 : 6 of alloy to mercury. The setting reaction of dental amalgam has been studied by many workers1–4 and is now accepted to be

Laminate Reinforced Dental Amalgam
Journal of Dental Research, 1972The flexural strength of amalgam specimens was increased significantly by the application of ductile metal laminates in regions that are subjected to tensile forces and perpendicular to the direction of the applied force. Laminates were silver-tin alloy, pure gold, pure silver, and silver-plated stainless steel.

abstract— The steady‐state creep rates of dental amalgams were measured and the creep rates were correlated with the microstructure of the amalgams. The influence of manipulation variables on creep rate and microstructure was evaluated. The samples were either mechanically or hand triturated, hand condensed, and stored at 20°C for 7 d.

SummaryThe relationship between microstructure and physical and electro‐chemical properties of copper‐containing dental amalgams has been discussed in an attempt to understand the role of copper in currently used dental amalgams.
