Aerosols in the Dental Setting: a Misty Topic.

Abstract Body: Since the start of the COVID-19 pandemic an innumerous amount of (mis)information and advice on how to stay safe and prevent the spread of coronavirus has been published. Airborne transmission of various pathogens has been identified in community and healthcare settings. Also viral transmission of airborne droplets/particles that have settled on surfaces has also been demonstrated. Especially in dentistry, due to aerosol-generating procedures there are potentially various infection risks for patients and those working in this field. Studies have shown that microorganisms in the mouth and respiratory tract can be transported in these aerosols, splash, and spatter. These can contaminate the mucous membranes of the mouth, respiratory passages, and eyes of the dental care professional as well surfaces and materials exposed in the environment. As such, it is important to prevent disease transmission within the dental practice. What preventive measures can and have been taken to counteract this and what have we learned during the pandemic?
