Question

Quizplus · Accepted Answer

The cingulum is the developmental lobe that makes up the bulk of the cervical third of anterior teeth.The lingually occurring cingulum is considered the fourth lobe of anterior teeth because anterior teeth are comprised of three other lobes,all positioned on the labial surface.The cervical line is the line that demarcates the cementoenamel junction (CEJ).A lingual ridge is the triangular ridge of a mesiobuccal cusp that runs to the center of an occlusal surface.A marginal ridge is a rounded border of enamel that forms the mesial and distal shoulders of occlusal surfaces of posterior teeth and the mesial and distal shoulders of the lingual surfaces of anterior teeth.Cusps occur on canines,premolars,and molars.Lingual cusps are positioned at the lingual aspect of teeth and assist in chewing and grinding functions.
