Mitigation of COVID-19 During Dental Treatment in a State Prison System.

In congregate living settings when active coronavirus disease 2019 (COVID-19) transmission is present, limiting the scope of dental care to urgent and emergent treatment minimizes exposure risk for patients and staff. Engineering controls to mitigate aerosol production during dental procedures, including enhanced high-volume evacuation, high-efficiency particulate absorbing air filtration, and the use of a dental dam provide additional protection for dental providers and staff. Properly fitted N-95 respirators are of particular importance to limit COVID-19 transmission when SARS-CoV-2 containing aerosols may be present. When patients are known to be COVID-19 positive, the use of powered air-purifying respirators is appropriate. Further protection against the spread of disease among patients and staff may be provided by point-of-care testing for patients prior to dental procedures during outbreaks.
