Chart of posterior teeth. In dentistry, the term posterior teeth usually refers as a group to the premolars and molars, as distinguished from the anterior teeth, which are the incisors and canine teeth. The simplest way of distinguishing between anterior teeth and posterior teeth is that posterior (back) teeth are situated at the back of the ...
The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. 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. Molars show a great deal of diversity in size and shape across the ...
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. The incisors cut the food ...
The mandibular third molar is the tooth located distally from both the mandibular second molars of the mouth with no tooth posterior to it in permanent teeth. In deciduous teeth, there is no mandibular third molar. For this tooth, there are great variances among third molars, and a specific of a third molar will not hold true in all cases.
The term posterior teeth refers to premolars and molars, as opposed to incisors and canines, which are anterior teeth. [1] [5] Proximal The surfaces of teeth that normally lie adjacent to another tooth. Proximal includes both mesial and distal, such as when referring to the proximal surfaces of teeth. [1] Quadrant
In the posterior teeth, both in upper and lower jaw, the lingual height of contour is found at the middle third of the inner surface of the tooth. The lower second premolar proposes an exception as its height of curvature in inner surface is located in the occlusal third of the inner surface.
Premolars can be considered transitional teeth during chewing, or mastication. They have properties of both the canines, that lie anterior and molars that lie posterior, and so food can be transferred from the canines to the premolars and finally to the molars for grinding, instead of directly from the canines to the molars.

Teeth also preserve better than bone, and so the sample of teeth available to archaeologists is much more extensive and therefore more representative. Dentition is particularly useful in tracking ancient populations' movements, because there are differences in the shapes of incisors, the number of grooves on molars, presence/absence of wisdom ...
