Abstract:
The ratio of concentrations of D-aspartic acid and L-aspartic acid in dentin of 27 premoars of different ages was determined with chiral capillary column gas. chromatography. Acidic isopropanol and trifluoroacetic acid anhydride were derivative agents. The linear regression between the degree of racemization and age was established, r= 0. 9568, SD= 4. 5 years. This seems to be a new method which is more accurate and objective than others in age estimation with teeth.
