Term
| Where are the incisal ridges worn on the incisors? |
|
Definition

Term
| how are the proximal outlines of the crowns of canines shaped? |
|
Definition
| proximal outlines of crowns are wedge or triangular with a lingual "S" shape |
|
|
Term
| which surface of the canine has a more curved CEJ? |
|
Definition
| mesial has more curve than distal |
|
|
Term
| traits seen in cuspids from the incisal view: |
|
Definition
(1) marginal ridges taper toward cingulum (lingual half narrower than facial half)
(2) lingual contour more curved (convex) than labial
(3) roots taper toward apex (and toward lingual) |
|
|
Term
| how many lobes form the facial surface of the canines? |
|
Definition
| three-- the middle of which forms the labial ridge which is more prominent maxillary canine |
|
|
Term
| mesial crown contour of maxillary canine |
|
Definition
| convex in middle third but nearly flat in cervical third |
|
|
Term
| mandibular mesial contour of canine |
|
Definition
| almost flat or convex and nearly in line with root contour |
|
|
Term
| mandibular vs. maxillary canine crown |
|
Definition
| mandibular appears bent more distally relative to root |
|
|
Term
| mandibular vs. maxillary canine cusp |
|
Definition
| mandibular cusp is more obtuse (more blunt) with mesial cusp ridge closer to horizontal |
