- The term “antemortem dental record” refers to all dental documentation collected before a person's death.
- These records include dental charts, radiographs, treatment notes, and models that serve as baseline data for comparison during forensic identification.
- They are crucial because they allow forensic experts to match postmortem findings with known dental characteristics, confirming an individual's identity.
- This contrasts with postmortem records, which are obtained after death.
- Hence, Option 1 is correct as it clearly states these records are from before death.
