[Risk for the influence of a chemical factor on dentists' health].

The paper presents data on air pollution of the working environment with chemical substances in dental rooms. The concentrations of chemical pollutants, such as mercury, lead, arsenic, disinfectants, drugs, and polymer dust in most working places have not been found to be more than the legally established MAC. Blood tests support that mercury has entered the workers' body. Mercury concentrations of in the dentists' blood correlate with those in the air. Chemical health risk is estimated to be low.
