Discuss disaster victim identification (DVI) in the context of a mass casualty event (e.g., train crash with 200 fatalities): (a) Interpol DVI protocol — primary (DNA, dental, fingerprints) and secondary (medical records, personal effects) identifiers. (b) Role of forensic odontology in mass disaster identification — dental charting, radiography, and comparative methods. (c) Psychosocial and ethical responsibilities of the DVI team toward families and role of the forensic physician in issuing death certificates in such events.
