The cingulum is highlighted near the base. In dentistry, cingulum (Latin: girdle or belt) refers to an anatomical feature of the teeth. 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]
The marginal ridges and the cingulum of the tooth are well-developed. The cingulum reaches incisally a great length and is large enough to create small fossa on either side of it. Depicted by the cementoenamel junction , the cervical line is the border between the root and crown of a tooth.
Dental work performed mostly in UK/Europe in last half of 20th Century. Tooth development is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth. Although many diverse species have teeth, non-human tooth development is largely the same as in humans.
The equivalent structure on upper molars is called the cingulum. The presence or absence of a cingulid is often a diagnostic feature for mammal remains. Some animals don't have a cingulid. Those that do may have them on only some, or all of the teeth, though most often on the molar teeth. It can be on the upper or lower teeth, or both.
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.
Edge-to-edge articulation is when opposing front teeth meet along their incisal edges when teeth are in maximal intercuspal position. [16] In Posselt's envelope this happens in ICP as the incisors of the mandible slide past the cingulum of the upper incisors to meet the biting edge and continue to maintain tooth contact as mandible protrudes ...
The teeth should all fit on a line of occlusion which, in the upper arch, is a smooth curve through the central fossae of the posterior teeth and cingulum of the canines and incisors, and in the lower arch, is a smooth curve through the buccal cusps of the posterior teeth and incisal edges of the anterior teeth.
Talon cusp will show physical signs of the irregular dental formation of the teeth and cause other symptoms of the disease that could possibly lead to dental problems in the future, depending on severity of the deformity. Most commonly, the extra cusp is located on the lingual surface, giving a three-pronged appearance. [5]
