Abstract

Introduction: Cheiloscopy is the study of lip prints; together with their morphological patterns, furrows, labial commissures can be achieved to identify a person, it is complemented with the correct use of reagents to obtain the lip print found on various surfaces. Objective: To analyze how cheiloscopy contributes to the method of identification of persons. Materials and Methods: Systematic review, qualitative approach, cross-sectional, retrospective search; descriptive and analytical design; deductive method. A search was performed using the meta-search engines Pudmed, Web of Sciene, Google Scholar, finding 88 scientific articles; according to the inclusion and exclusion criteria the sample was reduced to 30 articles, in which we proceeded to analyze classification systems, limitations, procedures, morphological patterns and gender in the cheiloscopy technique. Results: The most commonly used classification is that of Suzuki and Tsuchihachi, and it was possible to demonstrate that the morphological patterns existing in the lip prints are associated with gender, whether it is male or female. The conventional procedure within cheiloscopy is the most used. The articles comment that cheiloscopy is a complementary technique in criminal, legal or purely forensic odontological cases. Conclusion: Although it is a technique that has many limitations such as lack of technology, research, existing pathologies, among others; cheiloscopy is a complementary technique that can help forensic and forensic odontologists in the identification of gender of individuals.
