Sources of SARS-CoV-2 and Other Microorganisms in Dental Aerosols

0 4067

Alexandria, Va., USA — COVID-19 was declared a global pandemic in March 2020 and given an incomplete understanding of the transmission of SARS-CoV-2 at that time, the American Dental Association recommended that dental offices refrain from providing non-emergency services. As a result, 198,000 dentists in the United States closed their doors to patients. The study “Sources of SARS-CoV-2 and Other Microorganisms in Dental Aerosols,” published in the Journal of Dental Research (JDR), sought to inform infection-control science by identifying the source of bacteria and viruses in aerosol generating dental procedures.

Ventilation Assessment by Carbon Dioxide Levels in Dental Treatment Rooms

Alexandria, Va., USA — Carbon dioxide (CO2) is a byproduct of human metabolism and exists in high levels in exhaled air, and is therefore often used as a proxy for indoor air quality. The study “Ventilation Assessment by Carbon Dioxide Levels in Dental Treatment Rooms,” published in the Journal of Dental Research (JDR), evaluated CO2 levels in dental operatories and determined the accuracy of using CO2 levels to assess ventilation rate in dental clinics.
