Aerosols are solid or liquid particles which are ejected during dental treatments into air and develop air-borne infection. The aim of this study was to investigate the amount of bacterial aerosols during endodontic, periodontic and prosthodontic treatments. In this study, air samples were collected during three different dental treatments. This sampling was performed at four different distances from the patients' mouth within 7 days. The bacterial growth was assessed using blood agar plates. Data was analyzed using Kruskal-wallis test. The results obtained show that the greatest amount of aerosol was observed in prosthodontic treatment and the least value was shown during endodontic procedure (P<0.0001). Regarding the increased number of aerosols during prosthodontic treatments, preventive interaction for infection control is inevitable.
Key words: Bacterial aerosols, dental treatments, infection transmission, blood agar, air sampling.
