Researchers at Columbus-based Ohio State University College of Dentistry tracked aerosols generated during treatment of 28 patients undergoing ultrasonic scaling, implant osteotomy or restorative procedures. Thirty minutes after the procedure, condensate was collected from the operator and assistant’s face shield, the patient’s chest and an area 6 feet from the site of operation.
The researchers found that saliva did not significantly contribute as infection control measures such as preoperative mouth rinses and intraoral high-volume evacuation were used. The authors conclude that the risk for transmission of SARS-CoV-2 from aerosolized saliva is moderately low and that current infection control practices are adequately robust to protect both staff and patients.
