Maxillary Permanent Canine
General Characteristic Features
of the Canines:
1. The canines are placed at the
“corners” of the mouth, which
help in keeping facial expressions at
the cosmetic value.

2. The canines are the longest teeth in
the mouth.
3. The canines are the strongest teeth in
the mouth. WHY?
4. The canines are the most stable teeth
in the mouth because of
the followings:
A- They have large labio-lingual
dimension.

B- They have long roots, which are
well anchored in the alveolar
bone.

C- The crown shape of the canine
allows for “self-cleansing”, so
they stay for longer time.
5. The middle labial lobe is highly
developed incisally into a
strong, well-formed cusp.

The Permanent Maxillary Canine
Principal Identifying Features:
1. Single pointed cusp.
2. The distal slope of the cusp is longer
than the mesial slope.
3. Marked convex labial outline and
bulky palatal cingulum.
4. Very long single root.

Labial Aspect
1. The mesial outline of the crown is
convex from the cervical line to the
crest of curvature, which is located at
the junction of the incisal and middle
thirds.
2. The distal outline of the crown is D M
slightly concave from the cervical line
to the crest of curvature,which is
located at the center of the middle
third.

3. The tip of the cusp is in a line with
the center of the root.
4. The distal slope of the cusp is longer
than the mesial slope.
5. The cervical line is convex toward
the root.
6. The labial surface is smooth except
for a shallow depression mesially and
distally dividing the three lobes, with
the middle one much more developed
producing the labial ridge.

7. The root is long and conical, with
the apex curved distally.

Lingual Aspect
1. The tooth is narrower lingually than
labially (i.e., tapered lingually).
2. The cingulum in the maxillary canine
is larger than that in the maxillary
central and lateral incisors.
3. There is a well developed lingual
ridge confluent with the cusp tip,
which divides the lingual fossa
into two fossae.

Dr. Malak Alhuwaizi
4. There is a developmental
depression mesially and distally
extending for most of the root length.

Mesial Aspect
1. The labial and lingual outlines of the
crown are more convex than that in the
maxillary central and lateral incisors,
with the crest of curvature (labially and
2.5mm
lingually) located at the cervical thirds.
2. The curvature of the cervical line is
2.5 mm towards the cusp.

3. A line bisecting the cusp is labial
to a line bisecting the root.
4. There is a developmental
depression extending on part of the
root.

Dr. Malak Alhuwaizi
Distal Aspect
1. The curvature of the cervical line is
less distally than mesially (as in the
maxillary central and lateral incisors).
2. The developmental depression
of the root is more pronounced
distally than mesially.
Dental Anatomy lec 6
Dr. Malak Alhuwaizi
Incisal Aspect
1. The labio-lingual dimension is greater
than the mesio-distal dimension.
2. The ridge of the labial lobe is very
noticeable labially, with its greatest
convexity at the cervical third.
3. The cingulum is well developed and
makes a small arc when compared with
the labial outline which makes a large
arc.

4. The tip of the cusp is labial to the center
labio-lingually, and at or slightly mesial labial
to the center mesio-distally.

The Permanent Mandibular Canine
Principal Identifying Features:
1. The mandibular canine is narrower M D
mesio-distally and labiolingually
than the maxillary canine.
2. The lingual surface of the crown of
the mandibular canine is shorter than
that of the maxillary canine, with less
developed cingulum and less prominent
marginal ridges.
Dental Anatomy lec 6
Dr. Malak Alhuwaizi
3. The cusp of the mandibular canine is
not as well-developed as that of the
maxillary canine.
4. The tip of the cusp is not in a line
with the center of the root.
5. The mesial slope of the cusp is
shorter than the distal slope.
6. The distal outline of the crown is
more rounded than the mesial
outline.
Dental Anatomy lec 6
Dr. Malak Alhuwaizi
7. The mesial surface of the crown is
nearly straight with the mesial surface
of the root, with the contact area being
near the mesio-incisal angle.
M D
8. The distal contact area is located
more incisally than the
maxillary canine.
