Nouvelles données sur l’édification des molaires et l’estimation de l’âge dentaire des enfants par imagerie médicale et 3D : apports et perspectives

The Neandertals of northeastern Iberia: New remains from the Cova del Gegant (Sitges, Barcelona)

“…Tompkins (1996b) has noted that Neandertals show an advance in the mineralization of the posterior dentition but a delay in the P3, relative to the incisors. This relative advance in the formation of the molars was subsequently documented in other immature Neandertals, including Châteauneuf 2 (Colombo et al, 2013). Although no incisors are preserved in the Gegant-5 individual, the posterior dentition (P 4 and M 1 ) is slightly advanced relative to the C 1 , and the dental sequence is matched in the La Quina H18 Neandertal (Smith et al, 2010).…”

Qafzeh 9 Early Modern Human from Southwest Asia: age at death and sex estimation re-assessed

“…The parameters from the definition of ossification stages (Coqueugniot and Weaver 2007;Coqueugniot et al 2010) are implemented after the study of the Coimbra documented collection in Portugal (137 individuals aged between 7 and 29 years old from the 20th century). Accuracy of age estimation from skeletal development is thought to be more sensitive to environmental factors (Lewis and Garn 1960;Liversidge et al 1998;Cardoso 2007;Colombo et al 2013). In addition, as for the use of dental references, bone maturation criteria originate from current populations and might therefore lead to slight discrepancies in age estimations of prehistoric populations having different lifeways.…”

Langerhans cell histiocytosis or tuberculosis on a medieval child (Oppidum de la Granède, Millau, France – 10th–11th centuries AD)

“…Dental age estimations were performed using the maturation of 10 deciduous molars and canines [50], and 5 permanent molars and canines [51] by direct observation on isolated teeth, or by CT-scan for teeth still in place [52]. Bone age was evaluated through 11 measurements (lengths of left and right humerus, left and right radius, left tibia, left femur, right fibula, right pars lateralis, pars basilaris, right scapula, and width of right scapula) [53].…”
