Which of the following is a type of scientific identification?

• A. Surgical implants
• B. Bite marks
• C. Odontograms
• D. Anthropometry

Answer: (A)

Identifying a person from physical evidence often relies on items that carry a unique, traceable link to an individual. Surgical implants fit this role because they are manufactured with identifiers—serial numbers, lot codes, and manufacturer data—that can be connected to patient records in hospitals or device registries. If such an implant is recovered, investigators can query those records to confirm the person to whom the implant was issued, providing a direct, objective match anchored in documentation and the physical object itself. This makes implants a strong form of scientific identification.

Bite marks, while once considered for individual identification, are highly contested due to variability and interpretive subjectivity. Odontograms (dental charts) are useful for identification through dental records, but they rely on comparing known dental information rather than yielding a built-in, verifiable link like an implant with a serial number. Anthropometry involves skeletal measurements and is less precise for pinpointing a specific person in contemporary practice.
