Abstract
Splatter, droplet and aerosol, which potentially cause disease via contact and droplets transmission, may be produced during dental treatments. Through the risk model analysis of airborne diseases, it is clarified that the key points of preventing aerosol transmission are infection source management, increasing ventilation, reducing exposure time and correct use of protective masks. In order to reduce the aerosol pollution, it is necessary to strengthen the management of water and air piping systems and the control of splashing. Air and surface disinfection and enhanced personnel protection may reduce the risk. Based on the analysis of infection chain, this article elaborates the role of standard and additional precautions for cutting off the disease transmission chain. Systematic, comprehensive and evidence-based prevention and control measures should become our concerns.
