Oral healthcare settings are known to produce aerosols during dental procedures. With the outbreak of novel coronavirus, which has a definite droplet and possible aerosol transmission, a review of reducing bioburden due to aerosol generation in oral healthcare settings is warranted. Literature reporting characterization of aerosols in dental and medical settings, and potential for cross-infection in oral healthcare settings, was thoroughly reviewed. This was followed by reviewing studies and guidelines issued by various health organizations on methods of reducing the burden of aerosols in dental setting. Oral healthcare settings can serve as a potential site for cross-infection of diseases such as tuberculosis and severe acute respiratory syndrome. COVID-19 spreads principally by respiratory droplets and may spread through aerosols. Many dental procedures are associated with the generation of a high number of aerosols. Airborne contamination can be kept to a minimum by following the hierarchy of controls which includes triage, engineering, and workplace controls followed by personal protection equipment. The use of high-volume suction is highly recommended to reduce aerosols in the dental office. Preprocedural rinse with 0.2% povidone iodine is effective in reducing viral load against COVID-19.
