abstract
The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has attracted worldwide concerns because of its high person-to-person infectivity and lethality, and it was labeled as a pandemic as the rapid increase in the number of confirmed patients in most areas around the world became evident. The SARS-CoV-2 is mainly transmitted through respiratory droplets and close contact. There is also evidence of transmission through aerosols and digestive tracts. Because orthodontic treatment involves a large population who need routine return-visits, it was significantly affected and suspended because of the COVID-19 pandemic and the shutdown of the dental clinics and hospitals. Although the spread of COVID-19 has been effectively controlled in China, and many areas have gradually resumed work and classes, orthodontic participants are still under high risks of SARS-CoV-2 infection. This is due to the fact that the asymptomatic carriers of SARS-CoV-2 or patients in the incubation period may cause the cross-infection between orthodontic practitioners and patients. The close proximity between the practitioners and the patients, and the generation of droplets and aerosols that contain saliva and blood during treatment further increase the risks of transmission. Inthis article, we summarized the preventive strategies for control of SARS-CoV-2 transmission to protect both staff and patients during the orthodontic practice.
