Abstract: Since the outbreak of Coronavirus Disease 2019 (COVID-19), a large number of clinical trials affected by the epidemic are suspended and postponed, and clinical trial institutions have initiated a series of emergency management measures. The characteristics of the diagnosis and treatment of stomatology are that the doctors and patients are closed to each other face to face, it is easy to produce droplets and aerosols, and there are many invasive operations, which leads to high risk of cross infection. The epidemic of COVID-19 poses a huge challenge to the operation of stomatological clinical trials. This paper based on the epidemic prevention and control requirements and the consensus on clinical trial management under major public health emergencies, combined with the relevant work guidelines of the institution and the relevant clinical trial regulations, puts forward suggestions on the clinical trial operation management and protective measures during the epidemic period. It may be helpful to the stomatological clinical trial researchers and subjects during the period of COVID-19.

Key words: coronavirus disease 2019 (COVID-19), clinical trial, stomatology, epidemic prevention and control
