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.
Researchers at The Ohio State University College of Dentistry, Division of Periodontology, Columbus, USA, tracked the origins of microbiota in aerosols generated during treatment of 28 patients undergoing ultrasonic scaling, implant osteotomy or restorative procedures by combining reverse transcriptase qPCR, to identify and quantify SARS-CoV-2, and 16S sequencin

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.
Researchers at the University of Rochester, Eastman Institute for Oral Health, N.Y., USA, conducted CO2 concentration and ventilation rate assessments in 10 closed dental treatment rooms with varying air change rates by ventilation. Mechanical ventilation rate in air change per hour was measured with an air velocity sensor and air flow balancing hood.
