Abstract
El presente estudio, tuvo como objetivo, analizar los distintos patrones morfológicos presentes en
las huellas labiales de una determinada población costarricense y su correlación con las variables,
sexo, edad y afinidad biológica. Se analizaron 105 huellas labiales pertenecientes a estudiantes de
quinto y sexto año de la carrera de odontología de la Universidad de Costa Rica durante el II
semestre del 2016.
De las 105 huellas labiales analizadas mediante el método de Renaud, el patrón más prevalente fue
el tipo C de manera general, mientras que, de manera individual, en labio superior predomina el
patrón tipo A y en labio inferior predomina el patrón tipo C. De la totalidad de muestras analizadas,
se destaca que todas revelaron patrones distintos y la correlación estadística entre las variables,
sexo, edad y afinidad biológica, permitió conocer la existencia de elementos que podrían ser útiles
para identificación de individuos en el ámbito forense.
Los resultados demuestran que, con la aplicación de las técnicas adecuadas en la toma de muestras
y un análisis estandarizado, las huellas labiales pueden ser utilizadas en el ámbito forense como
método de identificación de individuos. Este estudio, además, pone en evidencia la necesidad de
realizar más investigación sobre huellas labiales en Costa Rica, no sólo por la necesidad de un
aumento en el número de muestras y así obtener mayores resultados estadísticos, si no también para desarrollar las herramientas necesarias en la toma, revelado y análisis de huellas labiales, así
como su aplicabilidad al servicio de la justicia costarricense.
The objective of this study was to analyze the different morphological patterns present in the lip prints of a certain Costa Rican population and its correlation with the variables, sex, age and biological affinity. 105 lip prints were analyzed belonging to fifth and sixth year students of the dental career of the University of Costa Rica during the second semester of 2016. Of the 105 labials analyzed by the Renaud method, the most prevalent pattern was type C in general, while, individually, in the upper lip, predominantly, the type of pattern, A and the lower lip, predominantly the type C pattern. Of the total of the analyzed samples, the different patterns and the statistical correlation between the variables, sex, age and biological affinity, remarks information that can be useful to identify individuals in the forensic field. The results show that, with the application of the appropriate techniques in the taking of samples and a standardized analysis, the lip prints can be used in the field of forensic science as a method of identification of individuals. This study also highlights the need to conduct more research on lip prints in Costa Rica, not only to increase the number of samples, but also to obtain more extended statistical results. Besides, this research can be used to develop the necessary tools in the taking, development and analysis of lip print. Moreover, the results obtained may be taken into consideration in order to improve forensic research in the Costa Rican justice system.
