Fingerprints are considered to be one of the most reliable methods of identification. Identification of an individual plays a vital part of any medico-legal investigations. Dermatoglyphics is a branch of science that studies epidermal ridges and ridge patterns. Epidermal ridges are polygenic characteristics that form intrauterine 10-18 weeks and considered fully developed by the sixth month of fetal growth. Fingerprints are permanent morphological characteristics and criminal detection based on fingerprints is based on the principle that no two people can have identical fingerprints. Sex determination from fingerprints has been examined in different population. In this study we aimed to study fingerprint ridge density in Turkish population sample of Baskent University students. Fingerprints were obtained from 118 women, 88 men a total of 206 students aged between 17 and 28 years old by means of simple inking method. Fingerprints from all right and left hands fingers were collected in three different area of each. The ridges on fingerprints were counted diagonally on squares measuring 5 mm × 5 mm on radial, ulnar and inferior areas. The fingerprint ridge density in radial, ulnar and inferior areas and between sexes was compared statistically Mann Whitney U test and Friedman test. The ridge density was significantly greater in women in every region studied and in all fingers when compared to men. The fingerprint ridge density in the ulnar and radial areas of the fingerprints was significantly greater than the lower area. Fingerprint ridge density can be used by medico-legal examination for sex identification.
指纹被认为是最可靠的身份识别方法之一。个体识别在任何法医学调查中都起着至关重要的作用。皮纹学是一门研究表皮嵴和嵴纹的科学分支。表皮嵴是多基因特征，在子宫内10 - 18周形成，在胎儿生长到第六个月时被认为已完全发育。指纹是永久性的形态特征，基于指纹的刑事侦查是基于没有两个人可以拥有相同指纹这一原则。在不同人群中都对通过指纹进行性别鉴定进行了研究。在本研究中，我们旨在研究巴斯肯大学学生这一土耳其人群样本中的指纹嵴密度。通过简单的油墨法从118名女性、88名男性，共206名年龄在17至28岁之间的学生获取指纹。收集了每只手左右手指在三个不同区域的指纹。在桡侧、尺侧和下方区域，在5毫米×5毫米的正方形上对角计数指纹上的嵴。采用曼 - 惠特尼U检验和弗里德曼检验对桡侧、尺侧和下方区域以及不同性别之间的指纹嵴密度进行统计学比较。在所研究的每个区域以及所有手指中，女性的嵴密度均显著高于男性。指纹的尺侧和桡侧区域的指纹嵴密度显著高于下方区域。指纹嵴密度可用于法医学检查中的性别鉴定。
