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.^{[citation needed]}

Shovel incisors are more common in East Asian populations and especially in Native American populations. East Asian homo erectus fossils also commonly have shovel-shaped incisors, a fact cited as an important piece of evidence for the multiregional hypothesis of human evolution.
