This document provides information about the permanent canine teeth. It describes the anatomy and dimensions of both the maxillary and mandibular canines. The maxillary canine is the longest tooth with a conical root and prominent cusp. It erupts around age 11-12 years. The mandibular canine resembles the maxillary canine but is narrower with slightly shorter roots. Both canines are important for guidance during jaw function and maintaining stability in the dental arch.

● Introduction
● Maxillary canine (all aspects)
● Dimensions of maxillary canine
● Mandibular canine
● Dimensions of mandibular canine

3. 1. Introduction
● The four canines are
placed at the corners of
the mouth .
● 3rd tooth from median
line
● Longest tooth
● Canine guidance
● Most stable teeth
● Self cleansing
● Canine eminence
● 4 lobes

5. Chronology of maxillary canine :
1) First evidence of calcification : 4-5 months
2) Enamel completed : 6-7 yr
3) Eruption : 11-12 yr
4) Root completed : 13-15yr

6. Maxillary canine
1) The outline of the labial or lingual aspect of maxillary
canine is a series of curves except for the angle made by
tip of cusp .
2) The labiolingual measurement of crown is about 1mm
greater than that of maxillary central incisor .
3) Cingulum shows greater development than that of
central incisor .
4) Root is thick labiolingually with developmental
depressions mesially and distally .

8. Labial aspect :
1) Labial surface of crown is smooth with 2 shallow
depressions mesially and distally . Middle labial lobe is well
developed this produces a ridge on labial surface .
2) A line drawn over crest of this ridge from cervical line to the
tip of cusp , is a curved one inclined mesially at its center .
3) Mesially crown is convex upto contact area .Above it , it is
concave .Contact area is at junction of middle and incisal
third .
4) Distally crown is concave between cervical line and contact
area . distal contact area is centre of middle third of crown .
5) Note the two levels of contact areas .
6) Root is conical with pointed or curved apex .

9. Labial aspect

11. Lingual aspect :
1) Crown and root are narrower lingually than
labially . Cervical line shows more even
curvature.
2) Cingulum is large and pointed like a cusp .
3) Below the cingulum are definite ridges
between marginal ridges .
4) Depressions are found between these
ridges .
5) Shallow concavities between ridges are
mesial and distal lingual fossae .
6) Mesial and distal surfaces of crown is
visible from lingual aspect .

13. MESIAL ASPECT :
1)shows greater bulk and greater
labiolingual measurement than any other
anterior teeth.
2)crown - wedge shape, cervical third
there is greater measurement .
3)labial outline and lingual outline
4)cervical line
5)root -conical

14. Mesial aspect

15. Distal aspect:-
1)somewhat same form as mesial
aspect.
2)cervical line exhibits less curvature .
3)distal marginal ridge is heavier and
more irregular in outline .
4)surface displays more concavity
above contact area.
4)developmental depression on root is
more pronounced .

16. Distal aspect

17. Incisal aspect :
1)labiolingual dimension is greater than
mesiodistal.
2)Tip of cusp is labial labiolingually and mesial to
the centre mesiodistally .
3)when cut cross sectionally mesial half has
greater bulk labiolingually
4)distal slope is longer than mesial slope .

18. Dimensions of
maxillary canine :

19. 1) Length of crown : 10.0 mm
1) Length of root : 17.0 mm
1) MD diameter of crown : 7.5 mm
2) MD diameter of crown at cervix : 5.5 mm
1) LL diameter of crown : 8.0 mm
2) LL diameter at cervix : 7.0 mm
1) Curvature of cervical line (mesial) : 2.5 mm
2) Curvature of cervical line (distal ) : 1.5 mm

20. 17mm

21. Chronology of mandibular canine:
1) First evidence of calcification :4 - 5 yr
1) Enamel completed :6 - 7 yr
1) Eruption : 9 - 10 yr
1) Root completed : 12 - 14 yr

22. Mandibular canine :
1) Bears a close resemblance to maxillary canine .
2) It is narrower mesiodistally than maxillary canine .
3) Labiolingual diameter is less.crowns longer than
maxillary. Higher contact areas .
4) The root may be as long as maxillary canine but
usually it is somewhat shorter .
5) Less cingulum development .
6) Less bulk marginal ridges .
7) Lingual portion resembles mandibular LI in crown .
8) Cusp not as developed as maxillary.
- Bifurcated roots a variation .

23. Dimensions of
mandibular canine :

24. 1) Length of crown :11.0 mm
2) Length of root : 16.0 mm
3) MD diameter of crown : 7.0 mm
4) MD diameter of crown at cervix : 5.5 mm
5)LL diameter of crown : 7.5 mm
6) LL diameter at cervix : 7.0 mm
7) curvature of cervical line (mesial) : 2.5 mm
8) curvature of cervical line ( distal ): 1.0 mm
