PERMANENT ANTERIOR TOOTH MORPHOLOGY - Mandibular Canines

Question 1

What has a longer cusp slope?

Answer 1

distal

Question 2

What do the red lines represent? (labial)

Answer 2

cusp slopes

mesial shorter than distal

Question 3

What does the blue line represent? (labial)

Answer 3

labial ridge

Question 4

What has a more prominent labial/palatal ridge, mandibular or maxillary canines?

Answer 4

maxillary canines

Question 5

What are the arrows pointing to? (labial)

Answer 5

developmental grooves

but not as pronounced as the maxillary canine.

Question 6

What do the structures represent?

Answer 6

Have a mesio-lingual and disto-lingual fossa (red)

Lingual ridge (blue)

We still have a cingulum (just less developed than max canine)

Question 7

What side is the mesial and what is the distal side?

Answer 7

mesial = left
distal = right

shorter mesial cusp slope

Question 8

Where are the connection points on the distal surface of the mandibular canine?

Answer 8

at the junction of the incisal and middle 1/3

Question 9

Where are the connection points on the mesial surface of the mandibular canine?

Answer 9

in the incisal 1/3

Question 10

Where is the CEJ placed on the mesial surface of the mandibular canines?

Answer 10

CEJ curve is more incisally displaced on the mesial wall

Question 11

When do the mandibular canines erupt?

Answer 11

9/10

Question 12

What side is more curved wall, the mesial or distal?

Answer 12

distal

Question 13

What has longer mesial-distal distance, maxillary or mandibular canines?

Answer 13

maxillary

Question 14

What has a more prominent lingual ridge, maxillary or mandibular canines?

Answer 14

maxillary

wider

(not as pronounced developmental grooves)

Question 15

What has a more developed cingulum?

Answer 15

maxillary

mandibular is less devolved and smoother

Question 16

Name structures A and B (INCISAL)
