Summary
Aspartic acid racemization in dentin provides accurate age estimation. A new, low-risk biopsy technique allows this method for living individuals, offering precise age determination across all age groups.
Area of Science:
- Forensic Science
- Biochemistry
- Anthropology
Background:
- Aspartic acid racemization in dentin is a reliable method for determining age at death.
- Ethical and legal concerns have limited its application to living individuals in Germany.
- A minimally invasive biopsy technique for dentin was developed to address these limitations.
Purpose of the Study:
- To evaluate the feasibility and accuracy of a novel dentin biopsy technique for age estimation in living persons.
- To assess the ethical and practical considerations of applying aspartic acid racemization to dentin biopsies.
Main Methods:
- A minimally invasive biopsy technique was developed for obtaining dentin specimens.
- Dentin biopsy specimens were analyzed for the extent of aspartic acid racemization.
- The correlation between racemization levels and chronological age was investigated.
Main Results:
- The dentin biopsy technique is a low-risk procedure with minimal discomfort.
- Standardized specimen removal is practicable with the developed technique.
- A strong correlation was observed between aspartic acid racemization in dentin biopsies and age.
Conclusions:
- Dentin biopsy for aspartic acid racemization is a precise and reproducible method for age estimation in living individuals.
- The technique is suitable for all age groups when performed under standardized conditions.
- This method offers a viable alternative to traditional age estimation techniques for living persons.
