He objective of this research is to establish the relationship that exists between the fingerprint formulas and the persons accused in homicides of the Peruvian population carried out in the Criminalistics Directorate of the National Police of Peru between the years 2013 to 2017. The type of study is Descriptive, longitudinal, retrospective, nonexperimental design (correlational) and approach quantitative. The population is of Peruvians composed of 2690 persons incriminated in homicides, regardless of their economic situation or if they are primary or recidivist, with a sample constituted by 626 people, of which 565 are men and 61 women. The documentary review technique was used through dactyloscopic (Alphabetic) tabs from which the first variable was obtained, such as dactyloscopic formulas, while for the second variable the types of homicides (qualified, guilty and simple), including the homicide and its attempt were obtained in both sexes and thus from their analysis together obtain a possible formula by sex that demonstrates a possible common pattern of all of them. Among the results we found that if there is a statistically significant relationship of 47% between the fingerprint formulas and the types of homicide of the people incriminated in homicides of the Peruvian population. For the statistical analysis, Pearson's Chi2 was used, completing said relationship in percentage of the summary table of contingency coefficients, with a significant value in both index fingers in men being the higher valued in law with 53.5%; and in women, a significant value was also found in both middle fingers, with a higher value in the left with 81.2%. Finally, a coincidence was found in the finger type and subtype (4 / i) on the ring finger of the left hand with 17% in both men and women incriminated in homicides, which could indicate the existence of a possible pattern common finger.

(Universidad Privada Norbert Wiener, 2012) García Díaz, Marco Aurelio; Quiroz Mejía, Jesús Miguel
La rugoscopia es un método seguro y de bajo costo que puede emplearse como una técnica alterna en lo referente a los procesos de reconocimiento de cadáveres o de personas no identificados. Este trabajo estudió mediante el análisis rugoscópico y la clasificación morfológica del Dr. Basauri, la forma y posición de las rugas del paladar en dos géneros diferentes. El análisis se realizó en los calcos rugoscópicos de modelos de estudio, obtenidos de pacientes que acudieron a la Clínica Odontología de la Universidad Privada Norbert Wiener durante el período de atención 2012-I. Se utilizó una ficha denominada Cuadrícula Rugoscópica Estandarizada de sus siglas (C.R.E.) diseñada y validada como instrumento de recolección de dato; además, se usó 100 modelos de estudio del maxilar superior pertenecientes a 52 varones y 48 mujeres y fotografías intraorales. Como resultados se observó que los tipos de ruga 4 (sinuosa), 1 (recta) y 2 (Curva) presentaron mayor frecuencia de aparición y los tipos 5 (circulo), 8 (Raqueta) y 9 (Rama) los de menor frecuencia para ambos sexos. Se concluye que el tipo de rugas palatina se encuentran relacionadas con la posición, además se pudo apreciar la individualidad del número de rugas pues no hubo repetición descriptiva o código palatoglífico igual entre las personas lo que les confiere a las rugas palatinas el carácter de únicas e irrepetibles; condiciones que le permiten ser empleadas en los procesos de identificación forense. Así mismo, se demostró que la ficha utilizada en este estudio fue eficiente, útil y de fácil diligenciamiento.
