Area of Science:

  • Forensic Odontology
  • Bite Mark Analysis
  • Taphonomy

Background:

  • Bite mark distortion on skin is influenced by biting dynamics and body location.
  • Accurate bite mark identification is critical in forensic investigations.

Observation:

  • This study compared bite marks on different body regions in two homicide cases.
  • The analysis focused on the dynamic nature of bite mark infliction and subsequent distortion.

Findings:

  • A stepwise dynamic comparison of serial marks, considering jaw movement and skin distortion, proved effective for identification.
  • This method facilitated the identification of matching points between dentition and bite marks.
  • The findings suggest the possibility of reconstructing wounding dynamics from bite marks.
