Study Notes
Permanent Canines Overview
- Four permanent canines in total: two in maxillary arch and two in mandibular arch, with one per quadrant.
- Positioned at the corners of the mouth, enhancing cosmetic facial expressions.
- Noted for stability due to their large labio-lingual dimension, long wide roots, and self-cleansing crown shape.
- Develop from four lobes: three labial and one lingual, with the middle labial lobe forming a prominent cusp.
- Wider buccolingually than mesiodistally, with a convex labial outline featuring a labial ridge.
Unique Features of Canines
- Distal cusp slope longer than mesial cusp slope.
- Contact areas positioned at different cervico-occlusal levels, linked to adjacent tooth classes.
- Alveolar bone over canine roots presents as canine eminence.
- Longest and strongest roots among teeth, providing excellent anchorage.
Functions of Canines
- Assist and support other teeth during mastication.
- Primarily used for tearing, seizing, slicing, and chewing food.
- Contribute significantly to aesthetics.
Maxillary Canine Characteristics
- Labial aspect shaped trapezoidal or pentagonal, with a convex mesial outline.
- Distal outline slightly concave, with a longer distal cusp slope than mesial.
- Cervical line curves convexly towards the root.
- Smooth labial surface interrupted by shallow depressions, with a developed labial ridge.
Maxillary Canine Aspects
- Lingual aspect narrower than labial with a larger cingulum compared to incisors; features well-developed lingual ridge.
- Mesial aspect shows more convex labial and lingual outlines with a pronounced curvature of cervical line.
- Distal aspect has a less pronounced cervical line curvature.
- Incisal aspect wider labio-lingually than mesiodistally, with prominent labial lobe ridge and well-developed cingulum.
Mandibular Canine Characteristics
- Generally narrower mesiodistally and labio-lingually compared to maxillary canines.
- Less developed lingual surface and cingulum; cusp tip alignment differs from maxillary canines.
- Distal cusp slope is longer while mesial slope is shorter; crown shape less convex.
Mandibular Canine Aspects
- Labial aspect trapezoidal or pentagonal, with a nearly straight mesial outline aligned with the root.
- Distal outline less convex; cusp tip aligned with vertical root axis.
- Lingual aspect resembles labial but is narrower and less concave, with a shallow lingual fossa.
- Mesial aspect triangular in shape, less convex labial outline, and reduced curvature of cervical line.
- Distal aspect mirrors mesial features but with a flatter cervical line.
- Incisal aspect oval with a smaller cingulum compared to maxillary canines, and cusp ridges inclined lingually.
