Rights and Permissions

Infections in dental practice may be transmitted by several routes, including direct contact with blood, oral fluids, or other secretions, through indirect contact with contaminated instruments and surgical equipments, through contact with aerobiological contaminants present in either droplet spatter or the aerosols resulting from oral and respiratory fluids. Preventing the spread of air borne infection is gaining importance in dental set ups because a large number of bacteria and viruses are transmitted through this route and prove to be a health hazard for both patients and dental health care personnel. High-efficiency particulate arresting (HEPA) air filters are very effective in reducing bioaerosols, and hence, preventing air borne infection. This paper discusses the role of HEPA filters in controlling air borne infections in dental clinics.
