Shovel-shaped Incisor

Incisor whose lingual surface is characterized by a scoop reminiscent of a coal shovel. This scoop is formed by lingual extensions of the enamel from the mesial and distal sides of the tooth, or inrolling of the lateral borders. This tooth form is characteristic of certain Mongoloid populations first described in the literature by A. Hrdlicka in 1907. There is also a variant in which, additionally, a labial extension of enamel forms a scoop on the labial surface of the incisor.

Cf. barrel-shaped incisor.
