"cingulum"の定義と意味

What is "cingulum"?

The cingulum refers to a rounded ridge or prominence located on the lingual (tongue-facing) surface of the anterior teeth, particularly the incisors and canines. It is a natural anatomical feature formed by the enamel and acts as a structural support for the tooth. The cingulum can vary in size and shape among individuals, but its presence aids in maintaining the stability and strength of the tooth structure. Additionally, it serves as an attachment site for the periodontal ligament, which helps keep the tooth securely anchored in the jawbone.
