CONCLUSION A method for the estimation of individual age on the basis of the quantity of D-aspartic and D-glutamic acid present in any tooth was developed. A calibration diagram, based on the analysis of 126 teeth from persons of 17-86 years of age, was drawn up. The D/L ratios and the ln(l+D/L)(l-D/L) correlation as a function of age was presented. We applied these calibration diagrams for the analysis of a single tooth from each and every one of 65 adult persons with unknown ages from Fig. 1. Linear regression between the age of life of the individuals and the D/L aspartic acid ratio of their teeth
