Abstract:Coronavirus disease 2019 (COVID-19), an epidemic pneumonia caused by 2019 novel coronavirus (2019-nCoV), is of rapid spread and high contagiousness, and has been recognized by World Health Organization as a public health emergency. Once the elderly is infected, they are at high risk for severe illness and higher motility. So, great importance should be attached to their protection. Generally, oral diseases are quite common in the elderly, and the psychological stress in the epidemic period can aggravate the conditions. In outpatient dental clinics, dentists and patients are in very close contact, and a large number of aerosols are generated during operation. To avoid cross-infection and ensure epidemic prevention, oral treatment is currently performed only in case of emergency. Based on the psychological state and oral characteristics of the aged patients, we put forward to the treatment and preventive measures of oral diseases, analyze the significance of oral health for epidemic prevention, and make recommendations for oral diagnosis and treatment for the aged population in the epidemic period.
