The principle for age estimation by analyzing ¹⁴C in dental enamel, exemplified by two teeth from cases 30 and 15, respectively.

<p>Horizontal lines represent their radiocarbon values crossing the ¹⁴C bomb curve, and corresponding date of enamel formation indicated by the vertical lines crossing the abscissa. By subtracting the average formation time (arrows) for each tooth, the DOB of the person can be calculated (dashed vertical lines). The true DOB was 0.3 and 0.4 years, respectively, from the estimated DOB of these persons.
