Question

The root of tthis tooth may be bifurcated and has a deep linear mesial concavity. The distal concavity is less pronouncedd.

When bifurcated, the roots of a maxillarry first prremolar separate many mmillimeters apical to the cementoenameel junction
a. true
b. false

Answer 1

The correct option is A. True. The statement about the maxillary first premolar having bifurcated roots with a deep mesial concavity and separating many millimeters apical to the cementoenamel junction is true, reflecting its unique dental anatomy.

Step-by-step explanation:

The statement regarding the maxillary first premolar being bifurcated and having a deep linear mesial concavity with the roots separating many millimeters apical to the cementoenamel junction is true. The premolar is indeed one of the teeth that can have two roots, and the characteristics of its roots, such as the mesial concavity, are distinct from the other teeth.

The maxillary first premolar is often bifurcated, meaning it has two separate roots, and this anatomical feature can be an important consideration in dental procedures such as root canals or the creation of dental prosthetics like crowns and bridges.

The statement that the roots of a maxillary first premolar separate many millimeters apical to the cementoenamel junction when bifurcated is false. In a bifurcated tooth, the roots separate below the cementoenamel junction, not above it. The cementoenamel junction is the point where the crown and root meet, and it is located at the gum line.
