This document provides information about the maxillary permanent canine tooth, including its chronology, notation, position, function, description of anatomical aspects, anomalies, clinical considerations, pulp cavities, and occlusion. Key points include: - The maxillary permanent canine develops from 4-15 years of age and is the longest tooth in the arch. - It is notation is either 13, 23 using the FDI two digit system, or #6 or #11 using the universal numbering system. - Its functions include supporting maxillary incisors, incising food, providing esthetics, and guiding occlusion. - Its anatomical aspects like crown, root, and pulp cavity are described in detail for each view (

• Borders (4), maximum convexity.(Contact area
,crest of curvature).
• Surface structure.

14. Maxillary Permanent Canine
Notation??
There are 3 numbering or notation systems:
A.Palmer numbering system.
B.International (two digit) system. 13, 23
C.Universal numbering system #6,#11
3 3,

15. Maxillary Permanent Canine
Position?

16. Maxillary Permanent Canine
Function
• Support the maxillary incisors.
• Incision (shearing and tearing
of food)
• Esthetics (Canine eminence)
• Stability of restorations.
• “Canine guidance” : guide the
tooth into intercuspal position

 Labial ridge.
 2 developmental depressions on either side of the
labial ridge.

27. 1. Conservative treatment with esthetic restoration
should be the first choice to preserve the normal
facial shape.
2. Variations
o a cusp-like tubercle is found on the cingulum.
associated with Lingual pits or sharp pointed cusp tip
o The root varies in length
Clinical consideration

28. The canine may be malposed or impacted.

31. Pulp cavities

32. Anatomy of the pulp cavity
1. Pulp chamber
2. Pulp canal
3. Pulp horn
4. Apical foramen
5. Lateral (Accessory)canal
6. Supplementary canal
7. Anastomosis

34. General rules
1- The outline of the pulp cavity generally
corresponds to the external contour of the
tooth
2- Cusp anatomy  pulp horn
3- Root canal
several classifications but mostly at least one
root canal in each root /(branch)

39. Pulp cavities of maxillary canine
General out line
Description
Mesiodistal section (labial section)
I. pulp chamber & pulp canal
Labioligual section (Mesial section)
I. pulp chamber & pulp canal
Cervical cross section
Mid Root cross section

41. General out line
Pulp cavity of maxillary canine has LL>
MD measurement of any anterior tooth.
Longest root and longest root canal.

43. Labial section (Mesiodistal section)
• Pointed incisally represent the cusp, pulp
horn
• Widens near cervical limit and narrowest at
the cusp
Pulp chamber
• Same length from cervical third till apical zone
• Then taper to singleforamen
• Mesial or Distal curve may be presnt.
Pulp canal

44. Mesial section (labiolingual section)
• Pointed incisally
• Widens to the mid cingulumlevel
• Labial margin slightly convex
• Lingual marginbulging in cigulum
Pulp chamber
• LL>MD
• May taper gradually
• Or at apical third become greatly constricted while the
foramen is still larger than incisor.
• Foramen may be at the center or labial.
Pulp canal

45. Cervical section
 Ovoid and
wider LL
Mid root section
less ovoid,
sometimes circular
