Bioaerosols which carry potentially hazardous microbes, viruses, fungi and allergens are of important concern in dentistry because of their potential effects on the health of patients and of dental personnel. Objective: To assess the level of atmospheric microbial contamination before, during and after clinical procedures in multi chair dental environments and to compare the findings during each time. Methodology: Air sampling was performed from the respective dental departments by placing blood agar plates 2 feet away from the patients mouth before, during and after clinical procedures. Samples were incubated aerobically at 37$c for 48 hrs. Colony counting was performed and expressed as colonies per plate (c/plate). Results: The results showed that atmospheric microbial contamination was higher during the clinical procedures as compared to the levels before and after the clinical procedures.The largest bacterial colony counts were seen in the periodontics followed by endodontics and by pedodontics. t-test carried out, failed to demonstrate significant difference in the colony counts between the various departments. Conclusion: The study shows the increased risk of transmission of infectious agents to the dentists. Hence, all necessary preventive measures should be advised and need to be followed strictly.
