title: [Epidemiological investigation in five dental offices of the Clinic of Dentistry, Faculty of Medicine, Palacký University, Olomouc and of the Olomouc University Hospital].
abstract: The aim of this epidemiological investigation was to determine microbial contamination of surfaces, medical devices, and equipment in five outpatient dental offices of the Clinic of Dentistry, Faculty of Medicine, Palacký University, Olomouc and of the Olomouc University Hospital. The epidemiological investigation was carried out as a one-time detection of microbial contamination from selected at risk sites on the dental unit with chair and in its immediate surroundings that had been sampled before the staff and patients arrived in the morning. The rates of culture-negative results ranged from 6.0 % in the children's dental office to 17.3 % in the dental prosthetics office. No statistically significant difference in these rates was found between different types of dental offices. The most commonly identified microorganisms were coagulase-negative staphylococci and Bacillus sp. Pseudomonas aeruginosa often reported to be the cause of hospital infection was isolated from the spit-toon drain in most of the cases. No methicillin-resistant Staphylococcus aureus was cultured from the swabs. We believe that the microorganisms isolated from the at risk sites are indoor airborne pathogens initially present in aerosols and then deposited on surfaces during the time after working hours.
