“…KEYWORDS: forensic science, tenprint, ridge width, titanium dioxide, latent fingerprint, aging As a latent fingerprint ages, substantial visual (1) and chemical changes occur (2) that have an effect on the ridge morphology (3,4). The technique known as morphometrics has proven useful in discerning differences between men and women with respect to both the ridge density (5)(6)(7) and in the distribution of minutiae (8,9). It has been reported that aging causes ridge narrowing and a loss in the continuity of the ridges over time (10,11).…”

A methodology to estimate the time of latent fingerprint deposition would be of great value to law enforcement and courts. It has been observed that ridge topography changes as latent prints age, including the widths of ridges that could be measured as a function of time. Crime suspects are commonly identified using fingerprint databases that contain reference inked tenprints (flat and rolled impressions). These can be of interest in aging studies as they provide baseline information relating to the original (nonaged) ridges' widths. In practice, the age of latent fingerprints could be estimated following a comparison process between the evidentiary aged print and the corresponding reference inked print. The present article explores possible correlations between inked and fresh latent fingerprints deposited on different substrates and visualized with TiO . The results indicate that the ridge width of flat inked prints is most similar to fresh latent fingerprints and these should be used as the comparison standard for future aging studies.

“…Mundorff et al [5] observed significant interfinger differences in mean ridge breadths. We have noted significant differences in RC per finger as well, and this suggests the need for digit identification to enable more precise sex discrimination.…”

The degree of sex differences varies in different ancestral groups. Therefore, dermatoglyphic research on sexual dimorphism has focused on pattern and metric variation among different geographic populations [5] ABSTRACT Objective: The aim of this research was to derive probability formulae based on ridge counts (RC) that could be used to contribute to sex determination in human identification. Methods: A modified technique of obtaining RC that is not influenced by finger patterns was employed. RC from fingerprints of 200 male and 200 female Filipinos aged 18-57 years were collected and analyzed statistically. Results: Males had lower RC compared to females, and there were differences in RC per digit as well. Odds for sex discrimination were obtained for the thumb (15 or less is more likely to be male; 20 or more is more likely to be female), index finger (20 or less is more likely to be male, 22 or more is more likely to be female), middle finger (20 or less is more likely to be male; 23 or more is more likely to be female), ring finger (18 or less is more likely to be male; 22 or more is more likely to be female), little finger (20 or less is more likely to be male; 24 or more is more likely to be female), and when the digit was unknown (19 or less is more likely to be male; 21 or more is more likely to be female). Conclusion: Given the overall range of probabilities (P = 0.60-1.00), the formulae based on RC may be used to assist in sex determination of unidentified fingerprints in the Philippine setting.

“…Number of studies reported that the ridges of right hand were found to be coarser than the left hand (Cummins et al, 1994). It was evident that left hand have greater number of ridges than in the right (Gutie´rrez-Redomero et al, 2007) and finer ridges than the right fingers (Mundorff et al, 2014). But these observations may be influenced by sex (Gutie´rrez-Redomero et al, 2007).…”

The present study was aimed at determining the existence of FA in Hausa populations using thumbprint minutiae. The participants included 112 males and 105 females of Hausa Ethnic descent, aged between 18-25 years. The minutiae of the plain thumbprints were determined from a circle with radius that cut across the nucleus of the fingerprints. The result showed that in signed asymmetry bifurcation, crossbar, break, point/dot into ridges and point/dot between ridges exhibited sexual dimorphism. The left ward asymmetry in male was exhibited in bifurcation, cross bar, trifurcation bifurcation, break, bridge, opposite bifurcation, in "M" convergence, in "M" bifurcation and Point/Dot into ridges. Similarly, in female bifurcation, trifurcation bifurcation, enclosure big, opposite bifurcation, convergence, in "M" bifurcation and return exhibit left ward asymmetry. For absolute and composite asymmetry the significant differences was observed in end, enclosure (small), bridge and return. In the entire minutiae types only ridge bifurcation exhibited directional asymmetry in males and six other minutiae types in females. In conclusion, the presence of sexual dimorphism in thumbprint ridge minutiae was demonstrated in the present study. The leftward asymmetry was observed in both sexes in different types minutiae. Females were observed to exhibit directional type of asymmetry more than the males in this population.
