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.
  • The cervical line on the mandibular canine curves less toward the incisal portion.

    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
