Background and Aims: The SARS-CoV-2 virus, capable of airborne transmission through aerosols, poses a significant challenge in clinical settings such as dental clinics. The use of high-speed instruments, including handpieces and ultrasonic scalers, generates considerable aerosols that, if contaminated, may facilitate infection transmission. This study aimed to detect the presence of the  SARS-CoV-2 virus in the clinical and non-clinical areas of a dental clinic.

Materials and Methods: In this cross-sectional study, 20 air samples were collected from various sections of the Dental School of Arak University of Medical Sciences. Sampling was performed using a pump equipped with a filter for two hours at a flow rate of 5 L/min and a height of 1.5 m above the floor. The samples were transported under a cold chain, the viral RNA was extracted, and then were analyzed using a specific RT-PCR kit.

Results: Out of 20 collected air samples, 3 samples (15%) tested positive for SARS-CoV-2 RNA. Two from clinical departments (restorative and fixed prosthodontics) and one from a non-clinical area
(pre-clinic).

Conclusion: The findings of this study indicated that SARS-CoV-2 RNA was detectable in some air samples from both clinical and non-clinical areas of the dental clinic. These results highlight the importance of strict adherence to infection control protocols across all sections of dental clinics to minimize the risk of airborne transmission.
