Question

Which of the following teeth is a single-cusp tooth located at the angle between the anterior and the posterior portions of the dental arch, plays an important role in controlling mandibular movement, and is sometimes called the "canine tooth" or the "eye tooth"?

(A) Incisor
(B) Canine
(C) Premolar
(D) Molar

Answer 1

The tooth described is the canine tooth, which is a single-cusp tooth important for tearing food and controlling jaw movement. It lies between the incisors and premolars.

Step-by-step explanation:

The tooth in question is a single-cusp tooth situated at the juncture of the anterior and posterior parts of the dental arch, known as the canine tooth. This tooth is critically involved in managing mandibular movement and is often referred to as the 'canine tooth' or 'eye tooth'. There are four canine teeth in a human mouth, two situated on the upper arch and two on the lower. They are positioned next to the incisors and feature a pointed edge, or cusp, ideal for tearing food. Unlike the bicuspids or premolars, which have two cusps, or the multicuspid molars, canines are notable for their single, prominent cusp.
