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 ...

Journal of Esthetic and Restorative Dentistry, 2004
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 ...

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.

Dental amalgam and mercury [PDF]
Biology of Metals, 1989 Mercury concentration in intraoral air and urine of seven females with dental amalgam was measured before and after intake of one hard-boiled egg. A considerable decrease in mercury concentration in intraoral air was found. Twenty women with about equal dental amalgam status, with or without subjective symptoms related to dental amalgam, were also ...

Nature, 1972
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

European Journal of Oral Sciences, 1975
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.

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.
