Estimation of relation of D,L-forms aspartic acid has been recently used for an evaluation of age. It represents a relatively new method based on analysis of hydrolyzed dentine. Its amino acids are derived and analyzed by gas chromatography or liquid chromatography on a chiral column.

Evaluation of age of unknown deceased persons belongs to the most important ways to identification. For the time being, morphological methods are used, namely evaluation of age according to Gustafson's method from tooth grindings or by macroscopical estimation of abrasion, transparency of root dentine, alveolar atrophy and number of missing teeth. Evaluation of the data can be influenced by an individual failure and experience showed an age related decrease of precision. Recently, some papers occurred estimating a relation of D, L-forms of aspartic acid which depends on the age with a significant precision.
