cord-350990-tywbe4o2	Checchi, Vittorio	COVID‐19 dentistry‐related aspects: a literature overview	2020-07-05		.txt	text/plain	3715	168	43	The terms used for the identification of keywords were: COVID-19, 2019-nCov, Sars-CoV-2, COVID-19 transmission, Coronavirus pneumonia, Coronavirus infection, Severe acute respiratory syndrome, Atmospheric contamination, Droplets, Aerosol, PPE/DPI, COVID-19 guidelines, Airborne contamination, Masks and respirators, and COVID-19 dental-related aspects. Therefore, dental procedures can be considered as one of the most probable causes of Sars-CoV-2 infection because such procedures require close proximity to the patient's mouth, possess a risk of contact with saliva, blood and other biological fluids and involve the use of instrumentation that creates large aerosols 4, 19, 20 . Moreover Sars-CoV-2 demonstrates persistent adherence, for a maximum of 9 days, to various surfaces 1, 21 ; therefore, all surfaces and instruments in a dental clinic should be considered as potential sources of virus transmission because infected droplets from saliva or aerosols could land on any exposed surface 16, 19, 22 .	./cache/cord-350990-tywbe4o2.txt	./txt/cord-350990-tywbe4o2.txt
