12 Questions
What is the shape of the mesial slope on the buccal cusp of the maxillary first premolar?
Straight
Where is the buccal cusp tip located in relation to the buccal root on the maxillary first premolar?
At the central line of the buccal root
What is the shape of the distal slope on the buccal cusp of the maxillary second premolar?
Straight
How does the lingual root trunk length compare to the whole root length on the maxillary first premolar?
Half the length mesially and takes only the apical third distally
In which view does the buccal outline of the buccal root incline slightly lingually for the maxillary first premolar?
Proximal view
Where is the lingual root apex compared to the buccal root apex on the maxillary first premolar?
Shorter with a blunt apex
Which statement accurately describes the pulp cavity of maxillary premolars in the mesiodistal section?
It has a narrow pulp chamber that is pointed incisally.
In the labiolingual section of maxillary premolars, how do the root canals emerge from the pulp chamber?
As two root canals that emerge separately but reunite to open in the same foramen.
Compared to maxillary first premolars, what distinguishing feature is more prominent in maxillary second premolars?
The buccal ridge is more prominent.
In the occlusal aspect of maxillary premolars, which statement is true about the central groove and fossae?
First premolars have a longer central groove, and the mesial and distal fossae are nearer to the margins.
Which statement accurately describes the cusp ridges of maxillary premolars?
First premolars have longer mesial cusp ridges, and second premolars have longer distal cusp ridges.
Compared to maxillary second premolars, what distinguishing feature is more prominent in maxillary first premolars?
The mesial marginal ridge groove is more observed.
