Study Suggests Saliva Is Not the Culprit in Transmitting SARS-CoV-2 Via Dental Aerosols

Researchers from The Ohio State University (OSU) School of Dentistry took a close look at the origin of bacteria and viruses in dental aerosols in their article, “Sources of SARS-CoV-2 and Other Microorganisms in Dental Aerosols.” They investigated the bacterial and viral content of aerosols generated during ultrasonic scaling, implant osteotomy, and restorative procedures performed on 28 patients. Aerosol condensate was gathered from clinicians’ face shields, patients’ chests, and areas 6 feet way from where treatment was provided. Through DNA microbiome analysis, the study authors were able to determine that main source of contamination within dental aerosols was the dental irrigant. Interestingly, they did not find saliva to be a significant carrier of bacteria or viral debris; however, patients used a preprocedural antimicrobial mouthrinse before treatment and high-volume evacuation was utilized throughout all procedures. The results were published in the Journal of Dental Research. Click here to read more.
