“…Due to corrosion, Hg 2þ ions and microscopic amalgam particles are also released into the saliva. 1,11,16,19 Autopsy studies have demonstrated the presence of Hg in a variety of tissues including brain, kidney, thyroid, pituitary, skin, and blood. Tissue specificity appears to be related to the specific chemical form of Hg.…”

“…Amalgam, an alloy of mercury (Hg), is an excellent and versatile dental restorative material containing about 50% Hg, and the rest principally silver and small amounts of copper, tin, and zinc. 1 –3 Dental amalgam restoration has been used in dentistry for more than 150 years due to its low cost, ease of application, strength, durability, and bacteriostatic effects. 4,5 For various reasons, including the development of viable alternatives based on resins and ceramics, and perceptions of a dubious and frequently questioned level of safety, the popularity of amalgam restoration has declined.…”

The safety of dental amalgam as the primary material in dental restoration treatments has been debated since its introduction. It is widely accepted that amalgam restorations continuously release elemental mercury (Hg) vapor, which is inhaled and absorbed by the body and distributed to tissues, including the brain. The aim of the present study was to investigate whether the presence of amalgam fillings is correlated with brain Hg level. The Hg levels in the parietal lobes of the brains of 32 cadavers were analyzed with an atomic absorption spectrometer with the mercury hydride system. A total of 32 brain samples were tested; of these, 10 were from cadavers with amalgam fillings, while 22 of them were amalgam free. Hg was detected in 60.0% (6 of 10) of the samples in the amalgam group and in 36.3% (8 of 22) in the amalgam-free group. The average Hg level of the amalgam group was 0.97 ± 0.83 µg/g (minimum: 0.3 µg/g and maximum: 2.34 µg/g), and in the amalgam-free group, it was 1.06 ± 0.57 µg/g (minimum: 0.17 µg/g and maximum: 1.76 µg/g). The results of the present study showed no correlation between the presence of amalgam fillings and brain Hg level.

This article reviews some of the merging ethical issues in restorative dentistry. This is a branch of healthcare concerned with quality of life, since retention of functioning teeth is important in allowing a healthy diet to be consumed. Yet the supply of dentists is such that, in many of the world's poorest countries, extraction is the only viable option for treating tooth decay. Available repair materials present various ethical problems. Silver amalgam is being phased out in much of the world, because of environmental concerns with mercury, yet it is cheap and reliable. Alternatives have been developed, influenced by the West's preoccupation with appearance, yet these materials are difficult to place and are less durable than amalgam. These concerns lead to significant ethical problems, which are explored in this article. It concludes by proposing a way to deal with the emerging ethical problems.
