Coronavirus as a New Challenge for Infection Control in Dentistry: A Literature Review

 Modes of transmission of the COVID-19 virus are still unclear. The virus could spread through direct routes, including aerosols and saliva, and indirect transmission through contaminated surfaces. Dental practitioners produce airborne infectious particles especially when using rotary instruments during treatment. Oral fluids, blood, and oral mucosa are also sources of infection, so dentists are exposed to coronavirus more than other medical staff. Indeed, designing appropriate protocols and prevention strategies are highly important. In this review paper, we will explain and review the transmission pathways of the coronavirus, clinical signs of infected patients, dental office infection control, and dental treatment considerations.
