Automated biometrics-based personal identification of the Hunter–Schreger bands of dental enamel

Abstract: The use of automated biometrics-based personal identification systems is a ubiquitous procedure in present times. Biometrics has certain limitations, such as in cases when bodies are decomposed, burned, or only small fragments of calcified tissues remain. Dental enamel is the most mineralized tissue of organisms and resists post-mortem degradation. It is characterized by layers of prisms of regularly alternating directions, known as Hunter-Schreger bands (HSB). In this article, we show that the pattern variati… Show more

“…Ramenzoni et al (10) were the first to use the fingerprint identification and verification software (VeriFinger Demo 4.2, SDK ⁄ Fingersec) and could satisfactorily evaluate the uniqueness of Hunter-Schreger bands for personal identification. This prompted us to choose VeriFinger SDK v5.0 software for the analysis of enamel rod end patterns for personal identification in this study.…”

“…Note that image treatment has enhanced both contrast and the number of observed HSBs above mentioned work the HSBs pattern was represented through drawings due to the low contrast between dark and clear bands in the teeth analyzed. It is worth mentioning that the light source must be directed in the same direction of HSBs, since these structures work as optic fibers when exposed to direct light source (Ramenzoni & Line, 2006). Therefore, the visualization of horizontal HSBs require the light source to be horizontally oriented.…”

“…Differences in the structure of HSBs among the various groups of mammals may be used to infer phylogenetic relationships, diet adaptation (Tseng, 2012), in the identification of mammalian taxa of higher orders (Ferretti, 1999;Koenigswald, 1985;Line & Bergqvist, 2005;Maas & Thewissen, 1995;Stefen, 2001). The pattern of HSBs can vary greatly among humans and this characteristic can be used as a biometric-based parameter for personal identification in automated systems (Ramenzoni & Line, 2006). The analysis of HSBs has been hindered by technical difficulties.…”

“…El alto contenido mineral de los tejidos dentales, especialmente del esmalte, es responsable de su dureza y resistencia, por lo que permite la identificación de los cuerpos humanos (Ramenzoni & Line, 2006). En 1920, Ubaldo Carrea elaboró un método matemático que permite calcular la estatura del sujeto a partir de las dimensiones dentales (Carrea, 1920;Carrea, 1939).…”
