How can palatal radicular grooves be used in identification?

• A. They are common and non-distinctive
• B. They indicate age
• C. They can serve as distinctive markers when documented antemortem
• D. They prove identity alone

Answer: (C)

Palatal radicular grooves are a developmental feature on the root surface of some maxillary anterior teeth. In forensic odontology, such grooves can act as distinctive markers because their presence, shape, depth, and exact location can be unique to an individual and remain relatively constant over time. When there are antemortem records—like dental charts, photographs, radiographs, or impressions—that document these grooves, and the postmortem dentition matches them, they provide a verifiable clue that helps establish identity. They are not age indicators, and they do not prove identity on their own; they function as supporting, comparative evidence that strengthens identification when used alongside other features.
