Does mercury from amalgam restorations constitute a health hazard

摘要: Amalgam is the most extensively used implant material in dentistry. There have been no clinical trials of this substance and there are epidemiological studies that allow any conclusions on safety amalgam fillings. restorations continuously emit mercury vapour, which absorbed considerable quantities via lungs. A comparison with dose-effect relationships, obtained occupational studies, for certain effects kidneys central nervous system (CNS), suggests individuals unusually high emission from fillings at risk. It unclear whether or not clinically significant could be expected. The limited sensitivity available together insufficient knowledge possible host factors affecting resistance to mercury, implies other more severe susceptible cannot excluded. Information long-term organs than brain kidney sparse. Animal suggest possibility immune reactions i.e. development autoimmunity, primarily dose-dependent, but rather depend genetic susceptibility. From a toxicological point view, an unsuitable dental restorations.
