  • Summary

    Tooth Cementum Annulation Analysis (TCA), or Cementochronology, has been evolving over recent years with great potential for applied forensic sciences. The goals of this research is to evaluate if TCA can be used to accurately determine the chronological age at time of death and season at time of death for unaccounted for US service members and in forensic anthropology in general. Fifty teeth were processed, and analyzed by two independent observers for age and season at time of death estimations. Results indicate an average of 85% estimation success within a ±4 years range of documented chronological age. The last band of cementum was identified to the correct season in average 74%, with an interobserver agreement of 78%. This pilot study thus supports age at death estimation using TCA in forensic contexts, and suggests additional validation studies for season of death estimation.
