| Description: | Dermatoglyphics is an essential component of physical anthropology. It has a wide range of applications such as criminology, population studies, phenotypic genetic studies and plays a crucial role in forensic science. This study aimed to assess the matching accuracy of latent fingerprints on a non-porous surface, with a pre-recorded database of patent fingerprints of a given population. Fingerprints were obtained using Dermalog LF10 fingerprint scanner. One hundred and forty-six (95 patent and 52 latent) medical and dental students of College of Medicine, University of Ibadan were recruited using convenience sampling method. The fingerprints were made up of 650 male and 290 female patent fingerprints and 520 latent prints. Monochrome toner powder was used as a developer of latent fingerprints deposited on glass slides. Four hundred and twenty-two latent prints were well developed and admitted for qualitative and quantitative analysis based on set criteria: pattern recognition and minimum of ten minutiae within pattern area were used as the prerequisites for matching between patent and latent fingerprints. GraphPad Prism 7.0 was used for the test of mean of variables. Ulnar and radial loops pattern were the most common types in both patent and latent prints among males and females. The calculation of matching accuracy, precision, specificity, and sensitivity showed 87.4%, 86.7%, 62.4% and 96.5% respectively. The results of matching demonstrate the reliability and the efficacy of monochrome toner powder as a tool for latent fingerprint development and is thus recommended for latent print development in forensic investigations. |
