[Mercury concentrations in placing of amalgam fillings]

In a laboratory experiment a Mercury Vapor Analyzer was used to measure the mercury vapor concentration for 15 minutes during the filling of artificial cavities with amalgam. It was the object of this experiment to determine the effects of suctor type and condensation technique on the mercury concentration profile. When both suctors were used in the experimental "oral cavity" (420 m3), the mercury concentration was below 0.01 mg (Hg/m3. There was no statistically significant difference between mechanical and manual condensation.
