[A model study on air contamination at the stomatologic work place by use of the turbine].

Certain dental measures, e. g., the application of a turbine, an ultra-sonic hand-piece or a spray, produce aqueous, polydisperse aerosols which escape from the patient's oral cavity during treatment and contaminate the room air with micro-organisms from the oral microbial flora. An aerobacteriometric model study at a stomatological work place showed that the germ content of the air was significantly higher on days when the turbine was used than on days when it was not used.
