Here, we report on an experimental approach of simultaneous determination of various amino acids racemization (AAR) rates in teeth. We evaluated the measurements of aspartic acid (Asp), glutamate (Glu), and alanine (Ala) isolated from dentin. Asx D/L rates from total amino acid fraction, generally used for age estimation, showed high correlation (r = 0.98) with age. As Glx and Ala showed very slow racemization kinetics in TA, we performed further analysis of the acid-soluble protein (SP… CONTINUE READING
