Answer 12

A. (33,43)
B. Both the maxillary and mandibular canines are called the “cornerstone” of the mouth because they are all located three teeth away from the midline, and separate the premolars from the incisors

Answer 13

A. 33, 43
B. The location of the canines reflect their dual function as they complement both the premolars and incisors during mastication (A.K.A chewing.)
C. tearing of food.
D. The canine teeth are able to withstand the tremendous lateral pressure caused by chewing.

Question 14

5. Maxillary and mandibular canine
   C/ Structure of Maxillary and mandibular canine

Answer 14

1/ Size: on average, canines are the longest teeth in each arch, and the maxillary canine is the longest tooth in the mouth even though the mandibular canine crown is longer than the maxillary canine crown.
