Aluminium amalgam aluminium and reduce H from water, creating aluminium hydroxide (Al(OH)) and hydrogen gas (H). The electrons from the aluminium reduce mercuric Hg ion to metallic mercury. The metallic mercury can then form an amalgam with the exposed aluminium metal. The amalgamated aluminium then is oxidized by water, converting the aluminium to aluminium hydroxide and releasing free metallic mercury. The generated mercury then cycles through these last two steps until the aluminium metal supply is exhausted. Due to the reactivity of aluminium amalgam, restrictions are placed on the use and handling of mercury in proximity with aluminium. In particular, large amounts
Dental amalgam controversy years. All available world-wide research indicates that amalgam is not harmful to health... No Government or reputable scientific, medical or dental body anywhere in the world accepts, on any published evidence, that dental amalgam is a hazard to health." The Irish Dental Association provides additional detail in a published patient information letter. France has publicly recognized the safety and effectiveness of amalgam restorations. A position paper on the Association Dentaire Française website states that amalgam restorations have proven to have no biological or toxic effect. They also mention that no serious pathological fact has ever been observed and no general
