Dental care professionals are thought to be at enhanced risk of occupational exposure to SARS-CoV-2, but robust data to support this is lacking. The study 'COVID-19: Seroprevalence and Vaccine Responses in UK Dental Care Professionals,' published in the Journal of Dental Research (JDR), provides a longitudinal analysis of antibodies to SARS-CoV-2 spike glycoprotein, including early analysis of the impact of vaccination on the immune response.

 E-Mail 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 aeros...

 E-Mail 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 ventila...

 E-Mail Alexandria, Va., USA -- The clinical picture of COVID-19 in various target organs has been extensively studied and described, but relatively little is known about the characteristics of oral cavity involvement. The study "Frequent and Persistent Salivary Gland Ectasia and Oral Disease After COVID-19" published in the Journal of Dental Research ( JDR), investigated the presence and prevalence of oral manifestations in COVID-19 survivors. Researchers at the Università Vita Salute San Raffaele, Milan, Italy, profiled the oral involvement in 122 COVID-19 survivors, hospitalized and fol...

 E-Mail Alexandria, Va., USA -- Since the onset of COVID-19 the potential risk of dental procedure spray emissions for SARS-CoV-2 transmission has challenged care providers and policy makers alike. The study, "Mechanisms of atomization from rotary dental instruments and its mitigation," published in the Journal of Dental Research (JDR), found that there are multiple mechanisms for atomization of fluids from rotatory instruments and that parameters can be controlled to modify key spray characteristics during the current crisis. Using high speed imaging and laser light-sheet illumination, pro...
