• In response to the COVID-19 pandemic, guidance issued from the World Health Organization and the Centers for Disease Control and Prevention recommend minimizing aerosol generating procedures (AGPs) and adopting personal protective equipment and engineering practices when AGPs must be performed. Tracheal extubation, particularly when associated with coughing, produced particle levels 15-fold greater than intubation but 35-fold less than volitional coughing. [...]the study does not support the designation of tracheal intubation as an AGP. Comment: Dental procedures produce aerosol and splatter with the potential to transmit SARS-CoV-2, although the viral load and the degree of infectivity of dental aerosols and splatters remain unknown.2 This study provides a robust quantitative analysis of physical aspects of dental aerosol and splatter while performing commonly accepted aerosol generating dental procedures (AGDPs) with and without the presence of suction in real-world simulations. The ideal dental operatory has been estimated at approximately 12 m2 with highly variable air-exchange rates.3 At the time of this writing, other investigations are emerging that evaluate the impact of environmental factors (room size, air-exchange rate, open vs closed operatory design) on the distribution and persistence of dental aerosol and splatter.4 The degree to which environmental factors affect aerosol and splatter in the dental operatory setting will likely be challenging to define, given the high variability of dental office designs.
