Advances in Dental Research, 1992
The goal of this presentation is to describe the material as it is used clinically, explain why small quantities of Hg can be released, and suggest ideas for amalgams that do not release mercury. A set amalgam is a dynamic material that undergoes many microstructural changes during clinical use, related to both the elevated temperature and corrosion ...

Amalgamation mechanism in dental amalgam alloys
Journal of Materials Science, 1987Model experiments to explore the amalgation mechanism in conventional Ag3Sn and high copper single-composition dental alloys have been conducted by rotating alloy roda in liquid mercury at different speeds and for different durations. After removing the rod from the mercury, the vacuum volatilization technique was used to accelerate the supersaturation

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.

Dental Amalgam Stabilization by Selective Interfacial Amalgamation
Biomaterials, Medical Devices, and Artificial Organs, 1976The purpose of this investigation was to explore the feasibility of enhancing the electrochemical stability of dental amalgam restorations by a process of "selective interfacial amalgamation." If dental amalgam restorations can be selectively alloyed at the tooth-amalgam interface, to a minor thickness as compared with the dimensions of the bulk ...

The amalgam-free dental school
Journal of Dentistry, 2004To review the change in teaching of Restorative Dentistry at Nijmegen dental school over the period 1986 to the present.In 1986, class I and II resin composite restorations were included in the pre-clinical program. However, these courses still started with class I and II amalgam restorations.

This paper looks at the issues of the current amalgam controversy: the daily dose of mercury from amalgam, hypersensitivity to mercury, claims of adverse effects from amalgam mercury and alleged overnight "cures." In addition, the toxicity and allergenicity of the proposed alternative materials are examined with the same kind of scrutiny applied by the

The Science and Politics of Dental Amalgam
International Journal of Technology Assessment in Health Care, 1998AbstractDental amalgam—a mixture of elemental mercury and a silver-dominated metal alloy—has been the most widely used dental filling material for well over a century. Alternative materials exist but are not well suited for some important applications, and all are more expensive than amalgam. The toxic effects of occupational mercury exposure have long
