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]
Dental anatomy is also a taxonomical science: it is concerned with the naming of teeth and the structures of which they are made, this information serving a practical purpose in dental treatment. Usually, there are 20 primary ("baby") teeth and 32 permanent teeth, the last four being third molars or " wisdom teeth ", each of which may or may ...
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.
Sometimes it can also be found on the facial surface of the anterior tooth. [3] The term 'talon cusp' refers to the same condition as dens evaginatus; however, talon cusp is more specifically the manifestation of dens evaginatus on the anterior teeth. Talon cusp can be simply defined as hyperplasia of the cingulum of an anterior tooth.
The primary tooth will begin to show signs of development between 14 2 ⁄ 3 weeks and 16 1 ⁄ 2 weeks in utero, at an average of 16 weeks. [5]The permanent tooth typically will erupt between when the child is 8 or 9 years old, while the root will continue to mineralize until around 11 years old. [4]
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.
Teeth are depicted in left lateral view (left side and center of the image) or occlusal view (right side of the image). The positions of tooth features are described along four directions: mesial (forwards, towards the chin), distal (backwards, towards the jaw joint), lingual (inwards, towards the tongue), and buccal or labial (outwards ...
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.
