This entocristid is continuous with the lingual cingulum. It involves a bar of material placed along the cingulum of the anterior dentition. The molars also have such a lingual cingulum. It is usually seen beneath the cingulum or incisal edge. Many sources suggest that he came from the town of Cingulum in Picenum. Damage to the cingulum also simultaneously damages the hippocampus. The lingual surface tapers toward the cingulum. Talon cusp can simply be defined as hyperplasia of the cingulum of an anterior tooth. Two dissimilar flagella that are involved in locomotion are present in the cingulum and sulcus. The transverse flagellum is structurally complex and wraps around the cingulum. Around the neck of the crown, a thickened cingulum, or shelf, is present. The cingulum is a major association tract. Each of the teeth has a prominent cingulum (shelf) on the inner (lingual) side. The marginal ridges and the cingulum of the tooth are well-developed. The lower incisor edges lie anterior to the cingulum plateau of the upper incisors.
