amalgam

Millions of people have received amalgam fillings, although their popularity has dropped off in recent years..虽然近几年他们的普及程度有所减少，还是有数百万的人使用了汞合金填充物。

In 2006, with the review still incomplete, an independent FDA advisory panel of doctors and dentists rejected the agency's position that there is no reason for concern about the use of amalgam..2006年，审查仍未完成，一个独立的美国食品药品管理局医生咨询小组和牙医拒绝接受该机构的立场，即没有理由担心汞合金的使用。
