Question 3

Christine has sharp, pointed cusp tips on her maxillary canines. She is 12 years old and has endured some teasing about the "fang-like" appearance of her canines. She asks her dentist if he can change the shape of her canines. The dentist agrees that reducing the cusp tips will result in a positive change in Christine's appearance.
If the maxillary cusp tips are flattened, which teeth will they most resemble?
a. Maxillary central incisors
b. Maxillary lateral incisors
c. Maxillary first premolars
d. Maxillary second premolars

Maxillary central incisors:
If the maxillary canine cusp tips are flattened, this tooth will most closely resemble a maxillary central incisor because the dimensions and the outline of the canine are closest to those of the central incisors.
