3. General considerations
Crown wide MD.
MD is slightly less than the incisocervical
measurement.

4. Dr. Rooban Thavarajah
Maxillary Canine
Does not resemble incisor (except root)
MD constricted @ cervix
Mesial, Distal surface appear convex
A single well developed sharp cusp
Long mesial & Short distal slope
Line joining contact areas bisect line drawn
from cervix to tip of cusp
Roots – Long, slender, tapering and twice
crown length
5. LABIAL ASPECT
Mesial & distal outlines bulge convexly to
cervical line.
The height of contour - at level of contact area.
Mesial- distal contact areas - located - same
level incisocervically (@ different levels
permanent canine)
Dr. Rooban Thavarajah
6. LABIAL ASPECT
Mesioincisal slope is normally longer than
distoincisal slope
Cervical line - even curvature apically.
No developmental depressions or
imbrication lines in root surface
Dr. Rooban Thavarajah
7. PALATAL ASPECT
Prominent cingulum, lingual & marginal
ridges.
MP and DP fossae are present
A tubercle at cusp/ Lingual ridge
Root – a distal inclination
Dr. Rooban Thavarajah
8. PROXIMAL ASPECT
Labiolingually tooth is thicker
Cervical line depth is less as compared to
incisors and even less in distal aspect
Mesial - Similar to incisor except
Crown height – greater
Cervical third greater Labiopalatally
Distal
Reverse of mesial side
Dr. Rooban Thavarajah
9. Dr. Rooban Thavarajah
Incisal edge
Diamond shaped
Tip of cusp distal to centre of crown
Mesial slope longer than distal slope ( X of
Lower canine, similar to permanent teeth)
