Postmortem tooth loss is common during forensic identification. Careful handling of human remains is crucial to prevent further tooth loss, which can hinder identification.

Area of Science:

  • Forensic Anthropology
  • Dental Forensics

Background:

  • Teeth are vital for human identification but are often lost during skeletonization or exhumation.
  • High frequency of postmortem tooth loss necessitates investigation into its causes and implications.

Purpose of the Study:

  • To quantify and describe tooth loss in forensic contexts.
  • To differentiate between pre-mortem (extraction) and post-mortem tooth loss.
  • To simulate conditions affecting human remains during forensic identification.

Main Methods:

  • Examination of three distinct samples to assess tooth loss.
  • Quantification of dental spaces to identify missing teeth.
  • Distinguishing between ante-mortem and post-mortem tooth loss.

Main Results:

  • High prevalence of postmortem tooth loss observed: 41.37% (Sample A), 56.83% (Sample B), and 3.96% (Sample C).
  • Maxillary incisors were the most frequently lost teeth across all samples.
  • Significant differences in tooth loss rates were noted between the samples.

Conclusions:

  • Postmortem tooth loss is a significant challenge in human identification.
  • Careful recovery, transportation, and storage of cranial remains are essential.
  • Preventing tooth loss during forensic processes is critical to avoid compromising identification efforts.
