Permanent Canines

Question 1

what does the upper canine have instead of an incisal edge?

Answer 1

a pointed cusp

Question 2

what is the crown of the upper canine like?

Answer 2

convex with the middle region often heightened to a prominent ridge (runs longitudinally to end at the tip of the cusp)

Question 3

comment on the mesial and distal borders of the upper canine

Answer 3

the mesial border (mesial cusp slope) is shorter and less steeply inclined than the distal border (distal cusp slope)

Question 4

what is the palatal side of the upper canine like?

Answer 4

generally concave, often divided into two shallow fossae by a ridge connecting the cusp with the cingulum

Question 5

comment on the cervical undulation on the upper canine

Answer 5

it is greater on the mesial surface than the distal

Question 6

where is the mesial contact of the upper canine located?

Answer 6

more incisally

Question 7

where is the distal contact of the upper canine located?

Answer 7

the centre of the middle third of the crown

Question 8

what is the root of the upper canine like?

Answer 8

longest and strongest of human dentition, irregularly oval, usually slightly grooved both mesially and distally

Question 9

in comparison to the upper canine what is the lower canine like?

Answer 9

smaller and more slender, more symmetrical, shorter and weaker and flatter mesio-distally so it appears narrower and more slender

Question 10

what is the lingual aspect of the lower canine crown like?

Answer 10

cingulum, marginal ridges and fossae are less pronounced than in the upper canines, lingual surface is flatter (like lower incisors)

Question 11

what is the labial surface of the lower canine like?

Answer 11

ridges are less prominent, mesial border is shorter and less steeply inclined, labial surface is lingually inclined bringing the cusp into lingual position
