In the offices of North Carolina dentist Matthew Young, retired Chairman Boyd Haley of the University of Kentucky’s chemistry department assists in demonstrating how much mercury is released during drilling to remove a mercury filling from a tooth placed in a mannequin. Unlike in many dental offices, the experiment did not use a high-speed vacuum to suction waste from a patient's mouth. This is a scenario that happens everyday in dental schools and some dental offices. Courtesy of Randall Moore, director/producer of the documentary Evidence of Harm
