Study Notes
Maxillary Canine
-
Located at the corner of the mouth
-
Longest root in the dental arch
-
Importance: Supports facial muscles, maintains jaw stability, and aids in stabilizing other teeth. It's the most prominent tooth
-
Erupts between 12-13 years
-
Labial Aspect:
- Crown is narrower mesio-distally than central incisor
- Cervical line is convex towards the root
- Contact area is mesially at the junction of the middle and incisal thirds.
-
Convex from the mesial and distal sides with slight convexity
-
Tip of cusp is aligned with the center of root
-
Mesial slope of cusp is shorter than the distal slope; Labial aspect is smooth with depressions mesially and distally, which divide the aspect into three lobes (the middle lobe is more prominent)
-
Root is conical, with a blunt apex, and sometimes curved distally or mesially
Lingual Aspect
- Crown and root taper lingually
- Cervical line is more curved than the labial line
- Well-developed cingulum
- A lingual ridge extends down from the cingulum
- Two fossae (mesial and distal) situated between the marginal ridges
- Mesial and distal developmental depressions exist on most of the root length.
Mesial Aspect
- Labial and lingual outlines are more convex within the curvature of the cervical line.
- Slight convexity from the labial aspect to the tip of the cusp at the cervical third.
- Lingual aspect has convexity at the cervical third (cingulum), followed by a small concavity at the middle third, and a straight line to the incisal third.
- Cervical line curves to the cusp
- Root is blunt and conical shaped.
- Convexity present at all points, except for a flat area above the contact point.
Distal Aspect
- Similar to the mesial aspect, but with differences
- Cervical line is less curved
- Distal marginal ridges are more irregular compared to mesial marginal ridges.
- Deeper concavity above the contact point.
- Deeper developmental depression exists on the distal root
Incisal Aspect
- Labio-lingual dimension is greater than mesio-distal dimension
- Tip of the cusp is labial to the center of the crown (labio-lingually) and mesial to the center (mesio-distally).
- The middle lobe ridge is prominent.
- Cingulum is more prominent lingually.
Differences between Maxillary Incisor and Canine
- Canines have a single pointed cusp, while incisors do not.
- Canine's distal cusp slope is longer than its mesial slope.
- Canine possesses convexity on the labial and bulk cingulum at the palatal surface compared to incisors.
- Canines have longer roots with a triangular cross-section
- Canines have well-developed grooves mesially and distally on the root
- Canines have narrower crowns mesio-distally, but wider labio-lingually, than incisors.
- Canines have narrower roots lingually than incisors.
