As for dental amalgam, it is a kind of dental filling material with a long history, with good physical and mechanical properties, corrosion resistance, wear resistance and high compressive strength. However, mercury in amalgam materials exists in the form of alloy, so its performance is relatively stable, and there is no obvious health hazard to patients who use amalgam filling materials. However, doctors or nurses who are exposed to amalgam materials every day may inhale volatile mercury, which may lead to the risk of mercury poisoning. In addition, the medical waste produced by amalgam filling may also cause environmental pollution. Therefore, many medical institutions no longer use amalgam to fill teeth.
