Amalgam Danger by Dr. Benjamin Zander

The only beneficiary of this secretiveness is the amalgam industry, which raises even more concerns – from 2003-2009, Commissioner Margaret Hamburg served on the board of Henry Schein Inc., the largest distributor of dental products (including amalgam).  Owning the large amount of stock in a company she would regulate, she was given 90 days to sell it, but the amalgam rule had to be finished within her first 75 days (by July 28).   Clearly Commissioner Hamburg had a conflict of interest that should have prevented her from participating in the amalgam rule.
