Common questions
Why does the digital format matter for forensic dental identification?+
Because the image is immediately available as a file, it can be transmitted quickly between examiners, agencies, or jurisdictions and directly overlaid in software against antemortem records, speeding up comparison work that with film would require physical transport and manual light-box alignment.
What is being compared when a digital periapical radiograph is used for identification?+
The examiner compares specific dental and bony features visible in the image, such as root morphology, restoration outlines, and bone trabecular patterns, between the postmortem radiograph and an antemortem record from the same individual, looking for matching or discordant features rather than relying on overall image appearance alone.
