Evaluation of DNA in Human Teeth-Ante-Mortem and Post-Mortem Factors Affecting Degradation and Preservation: A Literature Review.

ABSTRACT: The identification of human remains is a major challenge in forensic science, particularly in cases of advanced decomposition. Human teeth are among the most resilient tissues to environmental and post-mortem degradation, making them a valuable source of DNA for forensic identification. However, DNA preservation in teeth is influenced by multiple factors that can compromise the success of genetic analysis.

Objective

This review analyzes the intrinsic and extrinsic factors affecting DNA preservation in human teeth, focusing on ante-mortem and post-mortem variables rather than the methodological aspects of DNA extraction and analysis.

Methodology

A review of the literature was conducted, evaluating studies that assess the impact of biological factors (such as dental structure,
