They are used primarily to grind food during chewing. The name molar derives from Latin, molaris dens, meaning "millstone tooth", from mola, millstone and dens, tooth.
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.

Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion .) Tooth formation begins before birth, and the teeth's eventual morphology is ...
Human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. As such, they are considered part of the human digestive system. [ 1] Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function.
Specimens are “armed” with “teeth” on their front and back — with eight to 14 “teeth” on their ventral or front side and 22 to 26 “teeth” on their dorsal or backside. Photos show ...
Wisdom teeth in the human mouth for permanent teeth. There are none in deciduous (children's) teeth. The third molar, commonly called wisdom tooth, is the most posterior of the three molars in each quadrant of the human dentition. The age at which wisdom teeth come through ( erupt) is variable, [ 1] but this generally occurs between late teens ...
Removable partial denture. A removable partial denture ( RPD) is a denture for a partially edentulous patient who desires to have replacement teeth for functional or aesthetic reasons and who cannot have a bridge (a fixed partial denture) for any reason, such as a lack of required teeth to serve as support for a bridge (i.e. distal abutments ...
Permanent teeth of right half of lower dental arch, seen from above. The dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition. In humans and many other species, the superior ( maxillary or upper) dental arch is a little larger than the inferior ( mandibular or lower) arch, so ...
