Dental Anatomy Exam 1 Questions With Complete Solutions
1. Clinical crown The portion of the tooth that is clinically visible
2. Anatomic crown The portion of the tooth covered by enamel
3. Axial surfaces Mesial, distal, facial, and lingual surfaces
4. Proximal sur- Can only be either mesial or distal
faces (Distal third molar surface is NOT a proximal surfac
- no contact)
5. Triangular ridges Ridges that descend from cusp tips of only
posterior teeth; descend toward the central part
of the occlusal surface (NEVER referred to as a
facial or lingual ridge!)
6. Triangular ridges
7. Cuspal ridges Descend from cusp tips in a lateral direction
either mesial- ly or distally (every posterior tooth
cusp has four ridges)
8. Cuspal ridges
9. Facial/lingual
ridges

10. Oblique ridge "Special Kind" of transverse ridge; union of the
triangular ridge of the distofacial cusp and the
distal cusp ridge of the mesiolingual cusp across
the facial-lingual perimeter of the occlusal
surface; NOT a "pure" transverse ridge (because
both are not triangular ridges)
11. Oblique ridge
12. Marginal ridges Rounded borders of enamel that form the mesial
and distal margins of the lingual surface of
anterior teeth
13. Marginal ridges
14. Lingual height of Convexity on the lingual surface of posterior
contour teeth in the middle third of the crown
15. Lingual height of
contour
16. Lingual fossae Irregular depressions or concavities on the lingual
sur-
faces of the canines; either mesiolingual or distolingual
17. Lingual fossae
