PALATAL RUGOSCOPY AS A BIOMETRIC TOOL IN HUMAN IDENTIFICATION

Abstract

Introduction: Palatal rugoscopy is the analysis of the palatal ridges, unique to each individual, which remain almost unchanged throughout life. Its resistance to burns and decomposition allows its use in human identification, being a simple, effective, and low-cost method, applicable even to damaged or dismembered bodies. Objective: This study reviews the literature on the role of dentistry and palatal rugoscopy as a biometric tool in human identification. Methodology: The research was conducted in databases such as SciELO, PubMed, and LILACS (2020-2025), using descriptors like "Forensic Dentistry," "Human Identification," "Palatal Rugoscopy," "Forensic Biometry," and "Palatal Ridges," refined with connectors such as "AND" and "E." Results: The search in databases such as SciELO, PubMed, and BVS identified several publications between 2020 and 2025 on palatal rugoscopy. Most studies emphasize its application in human identification, with a particular focus on forensic use. Discussion: The study showed that palatal rugoscopy is a viable technique for human identification in forensic dentistry. It is based on the palatal ridges, unique and resilient structures located on the hard palate. Due to its low cost, non-invasive nature, and effectiveness, it stands out as a useful tool in forensic investigations. Conclusion: If pre-mortem data is available, the pattern of the ridges can be used to verify identity, making it useful in forensic dentistry.
