Canines

Question 1

The Max. canine cusp is located ……. for both mesiodistal and labiolingual diameter

Answer 1

in the center

Question 2

The Max. canine mesial cusp tip angle is …….. than the distal, which is …….

Answer 2

sharper (straight)
rounded
* The same is true for the Mand. canine

Question 3

The Max. canine buccal middle lobes run from …….., and the buccal height of contour is at ……..

Answer 3

the incisal edge to the cervical line
the junction of the middle and cervical third
* Same goes for the Mand. canine

Question 4

The Max. canine mesial contour is …….. with the height of contour at ………., while the distal contour is …… with the height of contour at ………

Answer 4

slightly convex (and flat or concave at the cervical third)

• at the incisal edge (junction of middle and incisal third)
• convex
• middle third

Question 5

The Max. canine lingual anatomy features ……

Answer 5

1. a prominent mesial and distal marginal ridges
2. a cingulum (the largest in the mouth)
3. a lingual ridge, running from the cusp tip to the cingulum, making a mesial & distal fossae
4. height of contour on the cingulum in the cervical third
   * Lingual pit may be present

Question 6

The root of the Max. canine is characterized by …….

Answer 6

mesial and distal concavities (with the distal being more distinct)
* Same goes for the Mand. canine

Question 7

An incisal view of the Max. canine shows …..

Answer 7

a round distal profile and flat (or concave) mesial profile

Question 8

The crown length of the Mand. canine is …… than that of the Max. canine

Answer 8

longer

* However, the total length is less than the Max. canine

Question 9

The Mand. canine is …… in mesiodistal width than the Max. canine

Answer 9

smaller

* Note that: the Max. canine is fatter than the Mand. canine

Question 10

The Mand. canine mesial profile is …… with the height of contour at …… , while the distal profile is …….. and the height of contour at ……

Answer 10

straight, at the incisal edge (at incisal third)

* convex, at the junction of the incisal and middle thirds

Question 11

The Mand. canine incisal tip is …… in labiolingual dimension

Answer 11

lingual

* Note that: the whole crown is distally inclined, unlike the Max. canine (in which the crown is in line with the root)

Question 12

The Mand. lingual anatomy is ……

Answer 12

same as the Max. canine, but less distinct

* Lingual pit is rare

Question 13

The height of contour & mesial, distal contact areas are …… on the Mand. canine than the Max. canine

Answer 13

higher
