Role of Droplets and Aerosols in Transmission of COVID-19 in Dental Practice: A Literature Review

This study sought to review the role of aerosols and droplets in transmission of coronavirus disease 2019 (COVID-19) in dental practice .

Published papers concerning the transmission routes of COVID-19 in dental environment were retrieved from the search engines, websites of related health organizations, and relevant electronic databases. Out of primarily retrieved 120 articles, 40 articles met the inclusion criteria.

Many Studies reported that the main transmission routes of COVID-19 were direct contact, droplets and aerosols. Because of the adjacency to the patient's oral cavity and use of aerosol-generating headpieces, dental practitioners are at high risk of COVID-19. Adherence to clinical protocols and guidelines in the working environment was highly emphasized in all studies to minimize the risk of infection and prevent cross-contamination in dental office setting.

Dental healthcare providers should be well aware of the most recent guidelines and protocols to prevent COVID-19 transmission and constantly update their knowledge in this regard.
