In forensic dental medicine, one of the most important endeavors is the estimation of age. We have studied the method of age assessment using the D/L ratio of aspartic acid from the dentin. The age of deciduous teeth has been estimated by measuring the racemization reaction of this amino acid. The r
Diastereomeric dipeptides were derived from the amino acid enantiomers in dentin by O-phthalaldehyde-N-acetyl-L-cysteine. The products were separated using high performance liquid chromatography (HPLC) and detected by fluorescence detector. A short analysis time (total analysis time was 15 min, incl
