[On the hazards of nosocomial infections in dental treatment areas (author's transl)].
Using a standardized method of obtaining bacterial counts of surfaces by superficial application and subsequent incubation of agar lamina, density and kind of bacteria present were examined in treatment areas of both individual dentists praxis and of dental poli-clinics. The results obtained showed, that 1. typical bacteria of hospital infections (Micrococcus aureus, Klebsiella) were present in only small numbers in both individual dental praxis or in clinical dental treatment areas. 2. the medium level of contamination was higher in the average individual dental praxis than in comparable clinical dental areas. 3. the increase in bacterial contamination in the course of the daily treatmentperiod was considerably more pronounced in the individual praxis as compared to clinics. 4. the following must be considered as especially liable to contaminated by bacteria: towels used by several persons, the head of the dental turbine, the support of the suction device, the patient head rest, the height control bar of the dental chair, the instrument tray, the operating lamp and working garments.
