Artificial neural networks reconstruct missing perikymata in worn teeth Open
Dental evolutionary studies in hominins are key to understanding how our ancestors and close fossil relatives grew from the early stages of embryogenesis into adults. In a sense, teeth are like an airplane's ‘black box’ as they record impo…

Severe Enamel Defects in Wild Japanese Macaques Open
Plane-form enamel hypoplasia (PFEH) is a severe dental defect in which large areas of the crown are devoid of enamel. This condition is rare in humans and even rarer in wild primates. The etiology of PFEH has been linked to exposure to sev…

Sexual dimorphism of deciduous canine dental tissues dimensions of modern human populations Open
The dental tissue proportions of human permanent canines are one of only a few sexually dimorphic features that are present in childhood, and therefore offer the opportunity to estimate the sex of immature individuals. This work aims to ev…

Middle Pleistocene hominin teeth from Biache-Saint-Vaast, France Open
The study of dental morphology can be a very useful tool to understand the origin and evolution of Neanderthals in Europe during the Middle Pleistocene (MP). At present, the earliest evidence, ca. 430 ka, of a pre-Neanderthal population in…

Early and Middle Pleistocene hominins from Atapuerca (Spain) show differences in dental developmental patterns Open
The Bayesian statistical approach considers teeth as forming a developmental module, as opposed to a tooth‐by‐tooth analysis. This approach has been employed to analyze Upper Pleistocene hominins, including Neandertals and some anatomicall…

Similarities and differences in the dental tissue proportions of the deciduous and permanent canines of Early and Middle Pleistocene human populations Open
The two‐ and three‐dimensional assessment of dental tissues has become routine in human taxonomic studies throughout the years. Nonetheless, most of our knowledge of the variability of the enamel and dentine dimensions of the human evoluti…

Testing the inhibitory cascade model in a recent human sample Open
The Inhibitory Cascade Model was proposed by Kavanagh and colleagues (Nature, 449, 427–433 [2007]) after their experimental studies on the dental development of murine rodent species. These authors described an activator–inhibitor mechanis…
