[Comparative assessment of technical approaches to estimating the biological age of a person using chromatographic analysis of dentin].

The study of the amino acid composition of dentin is a new approach to determining the biological age of a person in Russia. Abroad, this method is more studied, but the authors in their research use various equipment and reagents, which makes it difficult to find the optimal technical standard for implementation in domestic practice. We studied the literature over the past 5 years on age estimation by the amino acid composition of dentin. The equipment used in the work and the results obtained were compared. A comparative evaluation of the data made it possible to make an assumption about gas chromatography using mass selective or flame ionization detectors as a method of choice for studying the amino acid composition of tooth dense tissues.
