Abstract: BACKGROUND: Age estimation in living individuals is imperative to amicably settle civil and criminal disputes. A biochemical method based on amino acid racemization was evaluated for age estimation of living Indian individuals. DESIGN: = 90) were collected from participants with age proof documents and divided into predefined nine age groups. MATERIALS AND METHODS: Dentine biopsy from the labial aspect of the tooth crown was taken with an indigenously developed microtrephine. The samples were processed and subjected to gas chromatography. Dextrorotatory:levorotatory ratios were calculated, and a regression equation was formulated. RESULTS: Across all age groups, an error of 0 ± 4 years between protein racemization age and chronological age was observed. CONCLUSION: Aspartic acid racemization from dentine biopsy samples could be a viable and accurate technique for age estimation of living individuals who have attained a state of skeletal maturity.
