Our findings indicate that occupational exposure of dentists to mercury, even at low levels, is associated with a significant increase in the prevalence of symptoms of intoxication.
Systemic mercury levels caused by inhaling mist during high-speed amalgam grinding
This experiment has shown the following facts about the exposure of rats to an amalgam dust created by a high speed handpiece: 1.) The dust is almost immediately absorbed into the blood stream as shown by immediate increases detected by measuring the blood mercury content. 2. The heart receives extremely high levels of mercury within minutes after exposure. Eighty one times higher than the control level.
