Age assessment based on translucent dentine.

M Lorentsen, T Solheim

    The Journal of Forensic Odonto-Stomatology
    |June 1, 1989
    PubMed
    Summary

    The area of translucent dentine (ATD) in teeth correlates with age, with ATD proving a reliable indicator. This study compared ATD with Bang & Ramm and Johanson methods for age estimation.

    Area of Science:

    • Forensic Anthropology
    • Dental Age Estimation

    Background:

    • Age estimation is crucial in forensic and archaeological contexts.
    • Dental methods offer reliable age indicators due to tooth preservation.

    Purpose of the Study:

    • To investigate the correlation between age and the area of translucent dentine (ATD) at the root apex.
    • To compare the efficacy of ATD measurements with established methods (Bang & Ramm, Johanson) for age estimation.

    Main Methods:

    • Analysis of 500 non-molar teeth from diverse types.
    • Statistical analysis using regression models (SPSS/PC) to assess correlations.
    • Comparison of ATD with Bang & Ramm and Johanson aging techniques.

    Main Results:

    • Strong correlations between age and ATD were observed (0.57–0.83) across different tooth types.
    • ATD emerged as a preferred metric over other translucency measurements in regression analyses.
    • Johanson's method showed stronger correlations overall, while Bang & Ramm's was weaker, except for specific teeth.

    Conclusions:

    • Area of translucent dentine (ATD) is a significant and reliable indicator for dental age estimation.
    • ATD measurements, particularly when combined with factors like sex, enhance age prediction accuracy.
    • The study validates ATD as a valuable tool, offering a comparative perspective against existing forensic odontology methods.
