Three notable examples of evidence against amalgam from this time period include 1) a report from Dr. Amos Westcott warning that dental mercury could cause issues with the stomach and issues with gold fillings; 2) a case study published in the American Dental Review of a patient whose health improved after amalgam removal, and 3) the recommendation from Dr. Elisha Townsend, formerly a renowned proponent of amalgam, that the use of dental mercury should be avoided.

Dental amalgam has been widely used for over 150 years. It is made by mixing approximately equal parts of elemental liquid mercury (43 to 54 percent) and an alloy powder (57 to 46 percent) composed of silver, tin, copper, and sometimes smaller amounts of zinc, palladium, or indium [1].

Dental amalgam   Amalgam seems first to have been first used for the restoration of teeth in the different phases which have correspondingly different physical properties. toxic effects of mercury components. In this article, the mechanisms of dental amalgam corrosion are described and results of researches are reviewed. It finally  their low-copper amalgam counterparts, high-copper alloys exhibit the following physical properties: greater strength, less tarnish and corrosion, and less creep.

The pure form, elemental mercury, is liquid at room temperature and slowly Tooth filling materials Dental amalgams & alternative materials Mercury is a metal that can exist as the pure element or combined with other elements t

A conventional dental amalgam alloy will contain between 67% and 74% silver, with 25-28% tin, and up to 6% copper, 2% zinc and 3% mercury. The so-called dispersion type amalgam alloys have around 70% silver, 16% tin and 13% copper. The following is a simplified reaction; its notable feature is the lack of a γ2 (Sn-Hg) product: excess AgSnCu (the alloy) + Hg → unreacted alloy + Ag2Hg3 (γ1) + Cu6Sn5 1. The alloy contains 10% to 30% copper. 2. Silver reacts in the same manner as a low-copper amalgam, forming a γ1 (Ag-Hg) reaction product. 3.

Sodium amalgam, commonly denoted Na(Hg), is an alloy of mercury and sodium. The term amalgam is used for alloys, intermetallic compounds, and solutions involving mercury as a major component. Sodium amalgams are often used in reactions as strong reducing agents with better handling properties compared to solid sodium.
