Caracterización de los tejidos dentales de los caninos permanentes de las poblaciones actuales y del pleistoceno de la sierra de atapuerca, burgos, mediante microtomografía computorizada (micro-ct)dimorfismo sexual y otras inferencias paleobiológicas

Résumé

ABSTRACT In this PhD dissertation, we employed microtomographic image analysis techniques to assess the three-dimen¬sional dental tissue proportions of the permanent canines belonging to the Pleistocene populations of the Sierra de Atapuerca (Spain), as well as the canines of a large sample of modern humans of known sex. The main objective of this study is to explore the variability present in the dimensions of the different dental tissues of the populations under study and its utility to assess sexual dimorphism. The results obtained in this doctoral thesis allow to conclude that dental tissue proportions of permanent canines can be reliably used for sex estimation in extinct and extant populations, being especially useful in paleoanthropological and forensic contexts, where other skeletal elements are absent or often appear fragmented, and when we intend to estimate the sex of subadult individuals.
