Potential Risk Factors for Aerosol Transmission in the Dental Office and Strategies for Prevention and Control

Objective: Dental offices, due to the special characteristics of diagnostic and treatment operations and airborne diseases, are exposed to relatively closed environments with high concentrations of aerosols for a long period of time, and there is a possibility of disease transmission through aerosols. This paper introduces and analyzes the sources, distribution, hazards, and prevention and control strategies of oral bioaerosols, hoping to provide some references for reducing the hazards of oral aerosols and optimizing errors and omissions in dental treatment. Materials and Methods: By reviewing and summarizing the way of generating oral aerosols, the factors affecting their distribution in the past two decades, and reviewing the related literature, we explored the hazards of oral aerosols to the organism and the reasonable preventive and control measures. Results: Aerosol in dental clinic can spread through many forms, such as saliva of patients, water vapor splashing from dental high-speed mobile phone operation, etc., which increases the risk of infection between doctors and patients. Conclusion: A large amount of aerosols will be generated in the process of oral diagnosis and treatment, and the pathogens contaminating the air can directly lead to respiratory tract infections, and can also indirectly infect human beings through contaminated medical devices. The risk of aerosol transmission can be reduced through good scientific protection, standardized operation, rinsing and disinfection, and the use of isolation and strong suction equipment.
