Abstract

In forensic science, fingerprint analysis remains one of the most reliable methods for identifying individuals. However, this becomes challenging when dealing with decomposed bodies. Although various techniques are available, there is still a lack of a methodology that yields results quickly, particularly for retrieving and rehydrating mummified fingertips. Mummified tissue presents unique challenges for fingerprinting due to its rigidity, shrinkage, and other features that obscure epidermal ridge detail. This article overviews the rehydration solutions currently used to restore fingerprint details. These solutions include sodium hydroxide, sodium carbonate, ethanol, and recent advancements such as citric acid and specialized tissue conditioners. The efficacy of each solution is discussed in terms of effectiveness and the time required for rehydration. By summarizing these approaches, this article aims to inform forensic practitioners of the available techniques for rehydration and explore future prospects in this field.
