Study Notes
Mandibular Canine
- The crown of the mandibular canine is narrower mesiodistally and labiolingually than the maxillary canine, but similar in length.
- The root of the mandibular canine is usually shorter than the maxillary canine, but can be as long in some cases.
- The lingual surface of the crown is smoother, with less cingulum development and less bulk to the marginal ridges compared to the maxillary canine.
- The cusp of the mandibular canine is not as well-developed as the maxillary canine, with thinner cusp ridges labiolingually.
Contact Areas
- The mesial contact area is in the incisal third near the mesioincisal angle.
- The distal contact area is more cervical, at the junction of the middle and incisal thirds.
- Both contact areas are more incisal than those of the maxillary canine.
Root Variations
- A variation of the mandibular canine is bifurcated roots, which is not rare.
- Root curvatures are infrequent, but when present, they often occur in the mesial direction.
Crown Characteristics
- The crown of the mandibular canine appears longer due to its narrowness mesiodistally and the height of the contact areas.
- The mesial outline of the crown is nearly straight with the mesial outline of the root.
- The distal outline may be slightly concave in the cervical third and convex in the incisal two-thirds.
Comparison with Maxillary Canine
- The lingual surface of the crown is smoother and flatter, simulating that of the mandibular incisor.
- The cingulum is smooth and poorly developed, and the marginal ridges are less distinct.
- The lingual portion of the crown is narrower relatively than that of the maxillary canine.
- The tooth has less curvature above the cervical line labially and lingually, including the cingulum.
