Question

Single-rooted teeth that may have proximal root concavities; canines generally have proximal root concavities

Lateral incisors may have a palatal groove on the cingulum that extends on the cervical-third of the lingual surface
a. true
b. false

Answer 1

The statement is true. Canines can have proximal root concavities and lateral incisors can have a palatal groove on their cingulum.

Step-by-step explanation:

True. Single-rooted teeth, like the canines, indeed often have proximal root concavities. Canines are especially known for tearing food due to their pointed edge, and these teeth can present with proximal concavities along the sides of their roots. Additionally, lateral incisors may feature a distinctive palatal groove on their cingulum, which can extend down to the cervical-third of their lingual surface. Understanding the unique features of these teeth is important in dental anatomy and helps in identifying them in both clinical and educational settings.
