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 relatively more common in East Asian populations, particularly among certain Japanese and few Native American populations. The trait is not common and noticed among East Asian populations and even among Japanese population overall.
