	abstract = {<p>Enamel and dentin patterns have awakened a considerable interest in phylogenetic studies. However, almost nothing is known about the dental tissue proportions of European Pleistocene hominins, apart from Neanderthal populations. This study aims to assess the three-dimensional dental tissue proportions of permanent canines belonging to the extensive sample of hominin teeth at Sierra de Atapuerca (Spain) through the use of microtomographic techniques. Our results show that early and middle Pleistocene populations from Atapuerca exhibit large coronal and root dentine dimensions, as well as a thinly enamelled pattern, which has been traditionally considered an autapomorphic Neanderthal trait. Therefore, these results might support an early enamel thickness decrease which is already observed 800kyr ago in Homo antecessor and maintained in later groups such as Sima de los Huesos and Neanderthal populations during the middle Pleistocene.R{\'e}sum{\'e}Les patrons de proportions de l{\textquoteright}{\'e}mail et de la dentine ont {\'e}veill{\'e} un int{\'e}r{\^e}t consid{\'e}rable dans les {\'e}tudes phylog{\'e}n{\'e}tiques. Cependant, on ne conna{\^\i}t encore presque rien sur les proportions des tissus dentaires des hominid{\'e}s du Pl{\'e}istoc{\`e}ne europ{\'e}en, {\`a} l{\textquoteright}exception de celles des populations n{\'e}andertaliennes. La pr{\'e}sente {\'e}tude vise {\`a} {\'e}valuer les proportions tridimensionnelles des tissus dentaires des canines permanentes issues d{\textquoteright}un {\'e}chantillon exceptionnel de dents d{\textquoteright}hominin{\'e}s d{\textquoteright}Atapuerca (Espagne) en utilisant des techniques microtomographiques. Nos r{\'e}sultats montrent que les populations du Pl{\'e}istoc{\`e}ne moyen et inf{\'e}rieur d{\textquoteright}Atapuerca poss{\`e}dent des proportions de dentine radiculaire et coronaire {\'e}lev{\'e}es, ainsi qu{\textquoteright}un patron d{\textquoteright}{\'e}mail fin qui a {\'e}t{\'e} traditionnellement consid{\'e}r{\'e} comme un caract{\`e}re autapomorphique des N{\'e}andertaliens. Par cons{\'e}quent, ces r{\'e}sultats appuient l{\textquoteright}apparition pr{\'e}coce d{\textquoteright}une diminution de l{\textquoteright}{\'e}paisseur de l{\textquoteright}{\'e}mail depuis au moins 800\&nbsp;ka chez Homo antecessor. Ce patron d{\textquoteright}{\'e}mail fin est {\'e}galement observ{\'e} dans d{\textquoteright}autres groupes plus tardifs, tels que Sima de los Huesos et les populations n{\'e}andertaliennes pendant le Pl{\'e}istoc{\`e}ne moyen.</p>
