Coronavirus Disease-2019 and dental practice: A project on the use of ozonized water in the water circuit of the dental armchair

A novel coronavirus (2019-nCoV) is associated with human-to-human transmission. From its beginning in December 2019, the coronavirus disease 2019 (COVID-19) outbreak has spread globally from Wuhan and is now declared a pandemic by the World Health Organization (WHO). The person-to-person transmission routes of 2019-nCoV includes direct transmission, such as cough, sneeze, droplet inhalation transmission, and contact transmission, such as the contact with oral, nasal and eye mucous membranes. The participants in dental practice are exposed to a severe risk of 2019-nCoV infections because of the face-to-face communication and the exposure to saliva, blood, and other body fluids. Dental professionals play great roles in preventing the transmission of 2019-nCoV. Since ozone has a proven anti-viral action, we present a project on the use of ozonized water in the water circuit of the dental armchair, in order to lower the viral load during dental practice in dental clinics and hospitals.
