• Mandibular Right Permanent Canine

  
  

  Describe how many roots and cusps

  • one root

  -> distal side has a groove

  -> it bends towards the distal

  -> root is flattened mesiodistally (has an oval cross section)

  -> mesial slope of the cusp tip is shorter than the distal slope

  
• Mandibular Right Permanent Canine

  
  

  describe the palatal surface of the Mandibular Right Permanent Canine

  • Poorly developed cingulum

  • LESS developed marginal ridges compared to maxillary canine

  -> this produces shallow lingual fossa

  
• Mandibular Right Permanent Canine

  
  

  describe the labial surface of the Mandibular Right Permanent Canine


  • long axis of the tooth tilts towards the lingual resulting in the labial surface becoming convex whilst the lingual is concave
