Questions and Answers

What is a key difference between the cervical line of mandibular and maxillary canines?

The cervical line of the mandibular canine is horizontal.

Study Notes

Mandibular Canine

Similar to maxillary canines but narrower mesiodistally and labiolingually
Crown height is slightly longer than maxillary canine

Labial Aspect

Maxillary Canine:
- Crown wider mesiodistally
- Sharper cusp angle
- Shorter mesial cusp ridge than distal
- Mesial and distal proximal contacts more cervical
- Crown bulges beyond root outline
- More pronounced labial ridge
- Pointed root tip
Mandibular Canine:
- Crown narrower mesiodistally
- Blunter cusp angle
- Much shorter mesial cusp ridge than distal
- Mesial cusp ridge nearly horizontal
- Mesial and distal proximal contacts more incisal
- Crown outline almost continuous with root, little bulge
- Less pronounced labial ridge
- Blunter root tip

Lingual Aspect

Maxillary Canine:
- Prominent lingual anatomy
- Pronounced lingual marginal ridges
- Prominent lingual ridge and fossae
- Cingulum centered
Mandibular Canine:
- Smoother lingual surface
- Less pronounced lingual marginal ridges
- Less prominent lingual ridge and fossae
- Cingulum centered or slightly distal

Mesial Aspect

Less curvature labially on the crown, little curvature above cervical line
Curvature at cervical portion less than 0.5mm
Lingual outline similar to maxillary canine, but differing in degree
Cingulum less pronounced
Incisal portion of crown thinner labiolingually, making cusp more pointed
Cusp tip nearly centered over root
Cervical line curves more incisally than on maxillary canine
Root tip more pointed on mandibular canine
Developmental depression mesially on mandibular canine root is more pronounced

Distal Aspect

Little difference from maxillary canine, except for features mentioned in mesial aspect (common to both)

Incisal Aspect

Outlines of crowns are often similar
Mandibular Canine:
- Mesiodistal dimension smaller than labiolingual dimension
- Mesial surface less curved
- Cusp tip and mesial cusp ridge inclined lingually
- Distal cusp ridge and contact area extension are distinct
- Cusp ridges of maxillary canine are in a nearly straight line mesiodistally
