        Abstract
      Mass disasters cause damage, ecological disruption, and loss of human life on a massive scale. The reasons for these ranges from natural causes such
      as volcanic eruptions and earthquakes to secondary human causes like wars. Such massive disruption of life demands help from people belonging to
      various sectors of healthcare, providing pre‑identified, structured, and systematic aid to the victims of the disaster. This review article highlights the
      role of a dentist in such massive disasters. The dentist not only provides first aid to the victims but also aids in the identification of human remains.

      Role of Dentists During an Emergency
      The role of dentists in national emergencies has its origin
      since the inception of forensic field. During periods of intense
      military activity in Korea, as well as in World War II, dentists
      in conjunction with medical fraternity participated in the
      emergency care of the injured. The assignment of a specific
      role to an individual dentist depends on the state of organization
      of the Emergency Health Services at the community level.
      However, it is considered that the immediate needs in terms
      of professional personnel will be more critical in relation to
      primary treatment services, irrespective of the fields they are
      concerned with.[8] Apart from the routine duties, additional
      functions for dentists under mass casualty conditions would
