Abstract:At present, the epidemic situation of novel coronavirus infection is spreading across the country. Prevention and control of epidemic prevention has become the focus of hospital work. The stomatology department in the hospital has a large flow of outpatients with many oral diseases, which includes complicated types of oral bacteria. Patients cannot wear masks during diagnosis and treatment while medical staff's hands or medical instruments need to contact the patient's saliva, blood, and bacteria, especially in relatively closed environments. Especially in the relatively closed environment exposed to high concentration aerosols for a long time, it is possible to propagate through aerosols. The outpatient department of Stomatology of our hospital has refined the epidemic prevention measures through the preparation before the start of the clinic, emergency management during the clinic, disinfection and isolation management, which have achieved remarkable results, effectively ensuring the safety of doctors and patients.
