[Risks of mercury poisoning in the dental laboratory].

Abstract

We present the results of an inquiry about the hydrargyric risk run by the staff of an odonto-stomatological laboratory. A second laboratory in which mercury was not used, served as a control. It would appear that the staff in the laboratory where the practician uses amalgam have a level of mercury higher than that of the staff working in the control laboratory. This level reaches the maximum in the middle of the day and returns to the same level as that of the controls after the nights rest outside the polluted atmosphere. These results are discussed in the light of our findings and of facts obtained from literature.
