Ex Vivo Mercury Release from Dental Amalgam after 7.0-T and 1.5-T MRI.
Radiology, 2019T use of dental amalgam fillings remains popular despite the controversy surrounding its potential effects on human health (1–4). The American Dental Association has reported that 100 million amalgam filling procedures are performed every year in the ...

Preparation of a dental amalgam alloy from dental amalgam waste [PDF]
Journal of Materials Science Letters, 1984 Amalgam is universally the most used material for dental appliances. It is the result of mixing mercury with a silver-tin alloy. Dental amalgam contains about 50% mercury, 35% silver and 15% tin. Moreover it can contain smaller quantities of other substances such as copper and zinc.

A recently published British Standard specification for dental amalgam alloy (BS 2938:1985) departs considerably from the previous standard published in 1961. In order to assess amalgam alloys in accordance with the new standard, it was necessary to construct several pieces of equipment.

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 Journal of the American Dental Association, 1991
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
