This document provides information on the similarities between maxillary and mandibular canine teeth. It discusses their chronology of development, functions, and anatomical features. Key similarities include appearance of tooth buds at 5 months, initiation of calcification from 4-5 months, and crown completion time. Both canines have a single cusp, with the maxillary canine being the longest tooth in the arch. Features like the labial ridge, lingual ridge, and cingulum are present in both tooth types. The root of each canine is also long and slightly offset towards the distal.

4. Introduction:
 Canines are 3rd teeth from the mid line.
“Canine eminence” is the elevated bone ridge over the
labial portion of the roots.
There are four canines placed at the corner of the
mouth and hence called the „corner stones’ of the
dentition.
They have a single pointed cusp (also called cuspids):
Mesial Contact : with lateral incisors.
 Distal Contact : with 1st premolar.
 Longest tooth in the entire arch (both
crown & root).

Distal cusp ridge
Mesial Cusp Ridge

8. Labial aspects:
1. Shape: Pentagonal.
2. Labial Surface: is convex.
3. Incisal Outline: Mesioincisal slope is
generally shorter than distoincisal
slope.
4. Cusp Tip: is located directly over the
root center.
5. C.E.J: is curved towards the apex of
the root.
6. Regardless of the prominency Labial
ridge & Developmental depressions
are present in both canines.
7. Height of contour: is in the cervical
third.

10. Lingual Aspects:
1. Mesial , Distal and Incisal outlines:
are similar to their labial surface.
2. Cervical outline: asymmetrical and
offset towards distal.
3. Lingual ridge and Mesiolingual &
Distolingual fossae are the only
characteristic feature of canines.
4. Cingulum: is prominent in both canines.
5. Height of contour: is in the cervical
third.

12. Mesial Aspects:
1. Shape: triangular like incisors.
2. Dimensions: convex and widest labiolingually of any
anterior teeth .
3. Labial outline: entirely convex with height of
contour in cervical third.
4. Lingual outline: concane in incisal half and convex in
cingulum area.
5. C.E.J: is evenly curved incisally.

is similar to the Mesial surface
of its own.

16. Incisal aspects:
1. Shape: roughly diamond .
2. Cingulum: is offset towards distal.
3. Labiolingually: crown is thicker towards mesial
while distally it is thinner.

18. Root:
1. Roots of both canines are single and the longest
of the arch in which they are present.
2. Tip or Apex of the root is slightly offset
towards distal.
3. Wider labiolingually than mesiodistally.
4. Cross section at the neck of the root is roughly
ovoid.
