What is a typical first step in forensic dental identification when ante-mortem records are available?

• A. Compare dental work and radiographs with ante-mortem records to establish a match.
• B. Collect blood type data.
• C. Rely exclusively on dental wear.
• D. Ignore radiographs and rely on DNA alone.

Answer: (A)

The main idea is that ante-mortem dental data provide a unique fingerprint of a person’s dentition, so the first step is to directly compare the postmortem dental findings with those records. By examining the actual dental work—fillings, crowns, bridges, implants, and any distinctive restorations—and matching them to what appears in the ante-mortem radiographs, you can establish a direct concordance between the decedent and the person from the records. Radiographs reveal details that aren’t visible on the surface, such as the exact morphology of roots, root canal treatments, and the overall dental alignment, which helps confirm a match with high specificity. When multiple features align—same restorations, same tooth morphology and presence/absence, identical radiographic patterns—a positive identification is supported.

Other data, like blood type, can be useful as supplementary information but do not provide the same level of individual specificity as dental features. Relying solely on dental wear is not reliable because wear patterns can be common and non-unique. DNA analysis may be used in supportive roles or when dental data are inconclusive or unavailable, but the initial and most decisive step when ante-mortem records exist is the direct comparison of dental work and radiographs to those records.
