This document provides information about the maxillary canine tooth. It discusses the location and numbering of the tooth, its chronology of development, dimensions, and anatomical features visible from the labial, lingual, mesial, distal, and incisal aspects. Key points include that the maxillary canine is located distal to the central incisor, aids in cutting food and speech, and resembles the central incisor but has a more rounded outline and lingual fossa occupying 2/3 of the lingual surface.

2. INTRODUCTION
 Two in number
 Mesial side: Maxillary Central Incisor
 Distal Side: Maxillary canines
FUNCTION:
 Cutting food
 Speech and support for lips
 Supplements central incisor in function and
are similar looking

3. Tooth Numbering
 UNIVERSAL SYSTEM – 7 and 10
 PALMER – 2,2
 FDI Sytem – 12, 22

4. Chronology
 First evidence of calcification-: 10-12 months
 Enamel completed: 4-5 years
 Eruption: 8-9 years
 Root completed: 11 years

5. Dimensions
In mm
Cervico- incisal length of crown 9.0
Length of the root 13.0
Mesiodistal diameter of crown 6.5
Mesiodistal diameter of crown cervix 5.0
Labio diameter of crown 6.0
Labio diameter of cervix 5.0
Mesial curvature of cervical line 3.0
Distal curvature of cervical line 2.0

6. Labial Aspect
 Crown outline is trapezoidal
 Mesial margin is approax. Similar to Maxillary
Central incisor.
 Distal margin more rounded
than maxillary Central incisor.

7.  Mesio-incial and disto incisal line are more
rounded than maxillary Central incisor.
 Incisal outline is similar to maxillary central
incisor but not straight.

8. Lingual Aspect
 Mesial margin is more convex than maxillary
central incisor and
 distal margin is more rounded than maxillary
central incisor
 Lingual Fossa is deep triangular shaped and
occupies 2/3rd of lingual surface of crown.
Lingual 2/3rd

10.  Fossa will be rounded at the mesio-marginal
ridge which is straight and longer whereas
distal marginal ridge will be slightly curved and
small.

11. Mesial Aspect
 Very similar to the central incisor,
with lessened dimension
 Curvature of the cervical line is marked in the
direction of the incisal ridge.

12.  Root appears as a convex with like rounded
apical root end.

13. Distal Aspect
 Distal surface is smaller and more convex in
all dimensions than mesial surface
 Curvature of cervical line is usually a
millimeter or so less in depth than on mesial
side.

14. Incisal Aspect
 Resembles central incisor
 Cingulum may be large, as is the incisal ridge
 Labiolingual dimension may be greater than
usual in comparison with mesiodistal
dimension
 Exhibit more convexity labially and lingually
from incisal aspect than maxillary central
incisor

15.  Mesiolabial and distolabial line angles are
more rounded.
