Premolars Test Exam 2025 With 100%
Correct Answers
A patient is missing a premolar. After observing all of the premolars for comparative purposes,
you conclude that the missing premolar had: cusps of equal height, a short central
developmental groove, and several supplemental grooves.
Which missing premolar is this?
maxillary 1st premolar
maxillary second premolar
mandibular 1st premolar
mandibular 2nd premolar - CORRECT ANSWER✔✔maxillary second premolar
While examining one of your patients, you observe sealants in all 8 premolars. You note two
premolars have sealant material separated into mesial and distal pits. Which two premolars
does this describe? - CORRECT ANSWER✔✔mandibular 1st premolars
A prominent mesial concavity located apical to the contact area that continues onto the root is a
characteristic of a:
maxillary 1st premolars
maxillary 2nd premolars
mandibular 1st premolars
mandibular 2nd premolars - CORRECT ANSWER✔✔maxillary 1st premolars
Which premolar is typical of having a mesial crown cavitation or depression?
maxillary 1st premolars
, maxillary 2nd premolars
mandibular 1st premolars
mandibular 2nd premolars - CORRECT ANSWER✔✔maxillary 1st premolars
When compared to other premolars, which of the following characteristics is unique to a
mandibular 1st premolar?
The root is often bifurcated
The distal cusp ridge is shorter than the mesial cusp ridge
The lingual cusp is almost the same height as the buccal cusp
The occlusal groove pattern is shaped like a Y - CORRECT ANSWER✔✔The distal cusp ridge is
shorter than the mesial cusp ridge
Of the permanent premolars, the one that is most likely to have two pulp canals is the:
maxillary 1st premolars
maxillary 2nd premolars
mandibular 1st premolars
mandibular 2nd premolars - CORRECT ANSWER✔✔maxillary 1st premolars
When the cusps of the maxillary 1st premolars are compared:
The buccal cusp is longer but not wider
The lingual cusp is both shorter and more narrow
The buccal cusp is both shorter and wider
The lingual cusp is both shorter and wider - CORRECT ANSWER✔✔The lingual cusp is both
shorter and wider
Which premolar does not have a transverse ridge?
maxillary 2nd premolar
