Study Notes

Canine Teeth Characteristics

  • The canines are the strongest teeth in the mouth.

Stability of Canine Teeth

  • The canines are the most stable teeth in the mouth due to their large labio-lingual dimension and highly developed middle labial lobe, which forms a strong, well-formed cusp incisally.

Principal Identifying Features of Permanent Maxillary Canine

  • A developmental depression is present mesially and distally, extending for most of the root length.
  • The developmental depression is more pronounced distally than mesially on the root.

Mesial Aspect of Permanent Maxillary Canine

  • The mesial surface of the crown is nearly straight with the mesial surface of the root.
  • The contact area is located near the mesio-incisal angle.

Incisal Aspect of Permanent Maxillary Canine

  • The labio-lingual dimension is greater than the mesio-distal dimension.
