A cingulum connects the lingual and central cusps at the posterior margin of the tooth.
Circulate -us: having a cingulum or collar: see also cinetus.
This ridge, the cingulum, serves to protect the edge of the gums from injury by the hard parts of food.
In respect to their upper teeth, the incisors are small, equal, and have a hind cusp on the cingulum.
For this sash (Fig. 97) the more general terms zna and cingulum are sometimes used.
Posteriorly this single cusp in the cingulum is united with the hypocone.
Here, too, the cingulum is as high as the paracone and metacone.
The premolars are four in number, and in all the cingulum is fairly well seen.
