Oral outpatient procedures can produce large amounts of spray and aerosol. The treatment operation of the department of stomatology is mostly carried out in the oral cavity of a patient, a doctor is less than 50cm away from the patient, and the sprayed droplets and aerosol containing pathogens can directly enter the respiratory tract of the other side to pollute the air and articles in the surrounding environment. During the course of medical treatment, the medical personnel are exposed to the saliva or blood of patients containing pathogens, either directly or indirectly, which often exposes the medical personnel to the hazardous environment of pathogenic microorganisms.
In addition, a large amount of water mist particles, spray and aerosol with pathogens, which are generated when the medical ultrasonic dental scaler or a high-speed turbine handpiece is used for treatment, and dust generated by grinding in the department of mouth rehabilitation cause pollution to the environment. The prevalence rate of infectious diseases in China is on the rise, the occupational characteristics of medical staff in stomatology are more susceptible to viruses, and the incidence rate of infection is 2 times that of common people.
The major monitoring point in the present stage of China is mainly inpatients, but with the improvement of understanding of people on hospital infection, the occupational protection problem is referred to the working schedule by the medical community, and the serious pollution problem existing in the diagnosis and treatment process of the department of stomatology is taken as a weak link of hospital management, and has increasingly received wide attention of people in the medical community and all communities. Therefore, the enhancement of occupational protection for the oral medical staff has to be taken into account as a medical and social issue.
