Postmortem tooth loss is a significant challenge in archaeological contexts, especially in mass graves. This study found that time since death is the primary factor influencing tooth loss, impacting anthropological analyses.

Area of Science:

  • Forensic Anthropology
  • Bioarchaeology
  • Paleopathology

Background:

  • Unassociated human bones complicate mass grave exhumations and limit anthropological and paleopathological analyses.
  • While taphonomic factors are well-studied, postmortem tooth loss (PTL) and its influencing factors remain under-researched.
  • Understanding PTL is crucial for accurate interpretation of skeletal remains.

Purpose of the Study:

  • To investigate factors influencing postmortem tooth loss (PTL).
  • To analyze the relationship between PTL and postmortem interval, excavation methods, age, and periodontal disease.
  • To provide insights for careful exhumation of older skeletal remains.

Main Methods:

  • Analysis of three skeletal samples: a medieval church cemetery (110 individuals) and two mass grave samples from 1999 (402 individuals).

  • Quantification of postmortem tooth loss frequency.
  • Correlation analysis with postmortem interval, excavation techniques, age distribution, and alveolar bone loss due to periodontal disease.

    • Main Results:

    • Alveolar bone loss significantly influenced both antemortem and postmortem tooth loss.
    • Postmortem tooth loss frequency showed the strongest correlation with time since death.
    • Excavation methods, age, and periodontal disease showed less significant correlations with PTL.

    Conclusions:

    • Time since death is the most critical factor affecting postmortem tooth loss in archaeological contexts.
    • Alveolar bone loss is a significant predictor of tooth loss, both before and after death.
    • Increased care is recommended during the exhumation of skeletal remains from older contexts to preserve dental elements.
