What is the portion of the tooth covered by enamel?
Anatomic Crown; always the same
What is the portion of the tooth that is clinically visible?
Clinical Crown; varies with age
What are the surfaces that consist of the mesial of one tooth contacting the distal of the adjacent tooth except at the midline and on the distal surface of the third molars?
Proximal Surface
What are the surfaces that each posterior tooth has 4 of?
Axial Surfaces; mesial, distal, facial/buccal, lingual
Each posterior tooth cusp has ____triangular ridge.
one; triangular ridges are wider at the base than at the cusp tip
What are the raised or convex contours on the lingual surfaces of posterior teeth but are not on the cervical part of the crown? the biggest, bulkiest on the lingual surface
Lingual Heights of Contour
What is the angle formed by the junction of any two of the four surfaces of the anterior tooth?
Line Angle on the Anterior Teeth; the incisal ridge is not considered a surface.
What is the area on the chewing surface of the posterior teeth bordered by the crests of the mesial and distal marginal ridges, crests of the cuspal ridges, and the facial and lingual cusp tips?
Occlusal table
What is the a nebulous location of the entire occlusal contacting area that does not have clear delineating landmarks like the occlusal table does?
