A recent Ohio State University study published in the Journal of Dental Research found that 0.1% to 1.2% of microbes in aerosols distributed throughout the room during dental procedures were from saliva, while 78% were from irrigants. The findings suggest dental procedures pose a low risk for transmission of SARS-CoV-2, and support results of a study in the Journal of the American Dental Association, which found a COVID-19 positivity rate of less than 1% among dentists.
