| Abstract: | Disasteromeric dipeptides were derived fromthe amino acid enantiomers in dentin by O-Phtha-ladehyde-N-acetyl-L-cysrteine The products were seperated with High Performance Liquid Chromatography (HPLC) and were detected by fluorscece detector The . D / L ratio of aspartic acid in dentin of 20 first premolars was determined with the method, The interrelation coefficient between the D/L ratio of aspartic acid and actual age was 0. 9889. The etiamating error of ±one year of age was 40% , No estimating error exceeded five years of age was encountered. |
