Cingulum (tooth)

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] 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.
