Dental Nomenclature Exam Review Qs&As A+ Review Contact Area - ANS-Area on proximal surface that contacts the adjacent tooth. Named distal or mesial by location. Cusps - ANS-Elevated projections on the crowns of teeth. Incisors = incisal edge not cusp Canins = 1 cusp Premolars= 2 or 3 cusps Molars = 4 or more Example: Mesial Buccal Cusp Tubercles - ANS-Small extra elevation on the crowns of teeth(minicusps). Usually found on the lingual surface of maxillary anterior teeth. Mamelons - ANS-Small, rounded projections of enamel on the incisal ridges of newly erupted anterior teeth. They are worn away over time. Cingulum - ANS-Large, rounded bulge area in the cervical third on the lingual surface of anterior teeth. Ridges - ANS-Elevations on the surfaces of the crowns of teeth Marginal ridges - ANS-Elevation at the mesial and distal terminations of the occlusal surface of posterior teeth and the lingual surface of anterior teeth. They meet the cusp ridges at the point angles on posterior teeth. Anterior marginal ridges = vertical Posterior marginal ridges = horizontal Example: mesial marginal ridge...
