| description | Background: Effective removal of aerosols generated during dental treatment is crucial for maintaining biosafety in dental practice. This study aimed to measure the aerosol amount and the number of aerobic bacteria in the air during caries treatment. Methods: The study involved 50 molar teeth (n = 50) in the mandible in 50 patients divided into two groups based on the type of a high-volume evacuator (HVE); G1 (n = 25) conventional HVE (EM19 EVO, Monoart<sup>®</sup> Euronda, Vicenza, Italy) and G2 (n = 25) a new, wider, customized HVE. The PC200 laser particle counter (Trotec GmbH, Schwerin, Germany) was used to measure aerosol particles in a range of 0.3–10.0 μm near the operator’s mouth. The study used 60 microbiological plates with a microbiological medium (Columbia Agar with 5% Sheep Blood) to check the number of aerobic bacteria in the air. Results: The mean value of aerosol particles in the G1 group (conventional HVE) was 54,145 ± 7915, while in the G2 group (test, wider evacuator) was lower and amounted to 32,632 ± 1803. (<i>p</i> < 0.001). The median total bacteria count in the air per cubic meter in control, G1 (HVE), and G2 (NEW-HVE) groups were 50 [36-60]; 772 [643-881]; 120 [92-139], respectively. (<i>p</i> < 0.05). Gram-positive cocci were the predominant bacteria in the plates: <i>Micrococcus</i> sp. (50%), <i>Bacillus</i> species (36.4%), <i>Staphylococcus epidermidis</i> (3.8%), <i>Staphylococcus saprophyticus</i> (3.8%). Conclusions: the application of the wider high-volume evacuator increases the air purity during caries treatment as well as the biological safety of a dental office. |
