Clinical Trial Summary

Background: Maintaining biosafety in dental practice requires an efficient elimination of aerosols produced during dental treatment. The objective of this research was to assess the quantity of aerosols and aerobic bacteria present in the air during the treatment of caries. Methods: This study was divided into two groups based on the caries treatment method involving 60 patients with 60 m olar teeth (n=60) in the mandible. Group 1 (n=30) received a conventional dental turbine W&H Synea TA-98LC (W&H, Bürmoos, Austria), while Group 2 (n=30) received an Er:YAG laser (LightWalker, Fotona, Slovenia). Measurements of aerosol particles between 0.3 - 10.0 μm near the operator's mouth were taken using the PC200 laser particle counter (Trotec GmbH, Schwerin, Germany). The number of aerobic bacteria in the air was determined using 60 micro-biological plates with a microbiological medium (Columbia Agar with 5% Sheep Blood) and the sedimentation method. A control group G3 was established to measure the initial aero-sol level and the initial total number of bacteria CFUs (colony-forming units) before each treatment.

Secondary	Bacteriological study	The total number of aerobic bacteria in the air of the dental office was carried out by the Koch sedimentation method. The study used 60 Petri dishes with a microbiological medium (Columbia Agar with 5% Sheep Blood) to check the number of aerobic bacteria. Twenty plates were opened 60 minutes before the study (control group, n=20) and closed before the start of caries treatment. Next, forty plates were opened at the start of car-ies treatment with additional using a conventional evacuator (n=20) or a new evacuator (n=20) and closed 60 minutes after the treatment.	60 miniutes before the procedure
