Dental amalgam controversy pages, its research on the subject of amalgam safety concluded that "there is no scientific evidence for risks of adverse systemic effects exist ["sic"] and the current use of dental amalgam does not pose a risk of systemic disease." England and Scotland recognize the safety and effectiveness of amalgam restorations. A policy statement from the British Dental Health Foundation states that they do not consider amalgams containing mercury a significant health risk. Ireland recognizes the safety and effectiveness of amalgam restorations. The Irish Dental Association has published on their website: "Dental amalgam has been used on patients for over 150
Organosilver chemistry η-alkene complex. Silver is also present in other carbon-carbon bond skeletal rearrangements such as the quadricyclane to norbornadiene rearrangement, the cubane to cuneane rearrangement and the rearrangement of the cyclobutadiene dimer to cyclooctatetraene. Organosilver chemistry Organosilver chemistry in chemistry is the study of organometallic compounds containing a carbon to silver chemical bond and the study of silver as catalyst in organic reactions. In the group 11 elements silver is the element below copper. The chemistries have much in common but organosilver catalysis is much less common (mostly academic study) than organocopper chemistry due both to the relatively high price of
