For the outer (facial) surfaces of all teeth, the height of curvature is located in the cervical third of the teeth. In the inner (lingual) surfaces of anterior teeth, both upper and lower, the height of curvature is also located in the cervical third of the tooth, on the cingulum.
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.
Type III - Trace Talon: The projection originates from the cingulum (also known as the "cervical third") of the root and is enlarged or prominent in any form (conical, bifid or tubercle-like) [7] Since many cases of Talon cusp go unreported, it is hard to draw linkage maps but it is safe to assume that dental formation is influenced by genetic ...
The term anterior teeth refers to incisors and canines, as opposed to premolars and molars, which are posterior teeth. [1] Apical The direction toward the root tip(s) or apex(es) of a tooth (the apices), as opposed to coronal, which refers to the direction toward the crown. It may also refer to something relating to the roots, such as apical ...

It refers to the portion of the teeth that forms a convex protuberance at the cervical third of the anatomic crown. It represents the lingual or palatal developmental lobe of these teeth. [1] In zoology and palaeontology, cingulum refers to this feature only in the upper teeth. When this occurs in the lower teeth it is called the cingulid.
The animal’s fossil records date back 225 million years, predating the previously confirmed first mammal by approximately 20 million years.
The center of the incisal edge curves slightly downward in the center of the tooth. The cervical line, which is seen as the border between the crown and the root of the tooth, is closer to the apex of the root in the center of the tooth. This makes the cervical line appear as a semicircle in shape. [citation needed]
