Shovel-shaped incisors are teeth with thick marginal ridges surrounding a deep lingual fossa. They have a higher prevalance in Asian racial groups.

When present, shovel-shaped incisors can indicate correlation among populations and are considered to be one of the non-metrical traits in osteology.

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. Shovel-shaped incisors are significantly common in Amerindians from North, Central and … Näytä lisää

This gene is also linked to growth of thicker hair, increased development of sweat glands, and the shift to shovel-shaped incisors. The gene mutation is thought to have first occurred some 30,000...

Abstract. From dental casts of 94 parent-offspring and 127 full-sib pairs, sampled from two Chilean populations, shovelling indices are computed to measure the degree of shovelling of maxillary central incisors quantitatively. Genetic correlations are computed to determine the role of genetic factors in explaining the variation in this trait.
