Hol, P.J., Vamnes, J.S., Gjerdet, N.R., Eide, R., & Isrenn, R. (2001). Dental amalgam and selenium in blood. Environmental Research, 87(3), 141-146. doi:http://dx.doi.org/10.1006/enrs.2001.4308

It has been surmised that Selenium (Se) can protect against mercury (Hg) toxicity in humans thanks to the Hg-Se complex linked to selenoprotein P. In blood. The study in this peer-reviewed scientific journal measured Se concentrations in persons with health problems due to dental amalgam fillings. The Se concentrations of blood samples of 80 study participants were taken over the course of the study. Two groups were studied, one of which consisted of 21 healthy controls with amalgam fillings and 20 patients who claimed symptoms from existing amalgam fillings; the second of which consisted of 19 healthy controls with amalgam fillings and 20 symptomatic patients with the fillings. In the first...

However, the study concluded that it is possible that people who experience health problems related dental amalgam might have a Se metabolism different from those who do not and further research is warranted given the relatively small sample of the participants.
Given the lack of consistency of the results, the claim by the author that problems with dental amalgams and low selenium levels seems somewhat dubious. The study is in a scientific, rather than a dental journal, which points to its credibility and lack of bias, given that the authors have no apparent personal or financial interest in the results. But the study of the patients in total was extremely small. Each different grouping of approximately 20 experimental and 20 controls was very limited. There…

This is an article from one of the most respected daily newspapers in the United States on the use of mercury in dental amalgams. Mercury is a known toxin but the American Dental Association (ADA) points out that the Food and Drug Administration (FDA), the National Institutes of Health, the World Health Organization has not found any health risks from its use in dental work. Dental composites have risen in popularity as alternatives to amalgams for aesthetic as well as safety reasons, because they are tooth-colored. Amalgam is cheaper and ostensibly more durable, although some dentists prefer composite because it does not expand and adheres to the tooth. The article presents both sides of the amalgam vs. composite debate without taking a definite side on either issue.

The article is presented to a lay audience and is related from the perspective of someone who may be making a health-related decision regarding the pros and cons of which

Dental Amalgam: The Risks and Alternatives Some of the most common dental restorative materials currently in use are dental amalgams, but these compounds contain approximately 50% mercury making their use controversial, particularly with young children who may be harmed by long-term exposure.

In general, studies of commercial resin matrixes indicate volumetric shrinkage in the curing process as great as seven percent, with most undergoing shrinkage of two or three percent (Seghatol & Durand, 1999). In dentistry, the comparatively small dimensions of the products composed of polymers and the specific point-load stresses sometimes encountered by dentures magnifies the undesirable effects of even small percentages of incomplete polymerization and volumetric shrinkage. Moreover, dental materials
