[Bacterial contamination of the atmosphere of the dental surgery during preparation with turbin equipment. 2. Microbiological examination of water of stomatological sets].
Water forms a substantial part of aerosol particles formed during preparation with turbin equipment. The authors assessed therefore before aerobiological examination of the atmosphere of the dental surgery which will be the subject of part III whether the water used for cooling of dental sets is contanined by pathogenic bacteria. Microbiological examination of water specimens of the cooling system of four dental sets of two types revealed only the presence of Baccilus subtilis and Gram-negative rods. The results of aerobic cultivation of all 48 water specimens were identical. The authors did not find a difference between water samples at the beginning and at the end of working hours nor between specimens collected on different days. The measurements were made as part of a student contest and the results were presented at a student conference at the Faculty of General Medicine, Charles University Prague and in a nation-wide contest in Kosice.
