  2. Shovel-shaped incisors - Wikipedia

    en.wikipedia.org/wiki/Shovel-shaped_incisors

    Shovel-shaped incisors. Shovel-shaped incisors and non-shovel-shaped incisors. Shovel-shaped incisors (or, more simply, shovel incisors) are incisors whose lingual surfaces are scooped as a consequence of lingual marginal ridges, crown curvature, or basal tubercles, either alone or in combination.

  3. Sinodonty and Sundadonty - Wikipedia

    en.wikipedia.org/wiki/Sinodonty_and_Sundadonty

    The upper first incisors and upper second incisors are shovel-shaped, and they are "not aligned with the other teeth". [10] The upper first premolar has one root, and the lower first molar in Sinodonts has three roots (3RM1). [10] [5]

    The incisors also begin to show the shovel-shaped appearance, which can be attributed to a change towards a hunter-gatherer diet. [14] The reduction in molar size has been linked to the eating of softer foods, including cooked foods as well as more meat. [15]

  5. ASUDAS - Wikipedia

    en.wikipedia.org/wiki/ASUDAS

    The ASUDAS (Arizona State University Dental Anthropology System) is a reference system for collecting data on human tooth morphology and variation created by Christy G. Turner II, Christian R. Nichol, and G. Richard Scott. [1] The ASUDAS gives detailed descriptions for common crown and root shape variants and their different degrees of expression.

    Shovel-shaped incisors are commonly cited as evidence for regional continuity in China. [ 51 ] [ 52 ] Stringer (1992) however found that shovel-shaped incisors are present on >70% of the early Holocene Wadi Halfa fossil sample from North Africa, and common elsewhere. [ 53 ]

  7. Odontometrics - Wikipedia

    en.wikipedia.org/wiki/Odontometrics

    Odontometrics is the measurement and study of tooth size. [ 1][ 2] It is used in biological anthropology and bioarchaeology to study human phenotypic variation. The rationale for use is similar to that of the study of dentition, the structure and arrangement of teeth. There are a number of features that can be observed in human teeth through ...

  8. Maxillary central incisor - Wikipedia

    en.wikipedia.org/wiki/Maxillary_central_incisor

    The maxillary central incisor is a human tooth in the front upper jaw, or maxilla, and is usually the most visible of all teeth in the mouth. It is located mesial (closer to the midline of the face) to the maxillary lateral incisor. As with all incisors, their function is for shearing or cutting food during mastication (chewing).

  9. Homo antecessor - Wikipedia

    en.wikipedia.org/wiki/Homo_antecessor

    The upper incisors are shovel-shaped (the lingual, or tongue, side is distinctly concave), a feature characteristic of other Eurasian human populations, including modern. The canines bear the cingulum (a protuberance toward the base) and the essential ridge (toward the midline) like more derived species, but retain the cuspules (small bumps ...
