MPP worked extensively with Boston Common Asset Management, LLC, and other stakeholder representatives, in discussions with Dentsply, a major U.S. manufacturer of amalgam, in withdrawal of a stakeholder resolution, in return for Dentsply acknowledging that: 1) mercury from amalgam are released into the environment, 2) Dentsply offers alternatives to amalgam that dentists should consider using; 3) Dentsply will encourage dentist to reduce mercury releases; and 4) continue dialoguing to better understand amalgam impacts and then determine appropriate actions.
