[Bacterial contamination of the atmosphere in the dental surgery during preparation with turbine tools].

The aerosol formed during work with turbine tools has an undesirable impact on the environment of dental surgeries. It may cause atmospheric transmission of infection. Recent qualitative and quantitative evaluation of aerosols assumes theoretical knowledge of physical and chemical properties and transformation of the aerosol system. These findings which influenced the selection of methods of the author's more recent measurements are the subject of the submitted paper.
