Mix of all Flashcards
Which tooth is the exception to the following rule? Teeth with cusps will have a shorter mesial buccal cusp ridge than distal buccal cusp ridge
Maxillary First Premolar
Which molar has a non-functional cusp?
Mandibular First Molar
Of all premolars, which is the most symmetrical from facial to lingual when looking at an occlusal view?
Maxillary Second Premolar (with mandibular central incisor)
Which premolar is the only one to have a lingual height of contour in the occlusal 3rd?
Mandibular 2nd Premolar
On a maxillary premolar, what proximal view allows you to see the most occlusal surface
Distal
In which tooth does the buccal cusp take up 2/3 of the occlusal surface from an occlusal view?
Mandibular 1st premolar
Which has the greater O-C dimension, maxillary 1st premolars or maxillary 2nd premolars?
Maxillary 1st premolar
From which proximal view are all 3 cusp tips visible on a mandibular 2nd premolar and why?
Distal view; b/c the distal marginal ridge is more cervical than the mesial marginal ridge and the ML cusp > DL cusp
Where would you find a prominent mesial concavity?
Maxillary 1st Premolar
From an occlusal view, which tooth may have a slight divergence lingually?
Mandibular 2nd premolar
From an occlusal view, which tooth has a divergence lingually?
Mandibular 1st premolar
What are the only succedaneous teeth to NOT replace the same type of tooth?
Premolars (they replace primary molars→NO primary premolars)
On which tooth is the lingual cusp that is most variable in size of any premolar?
Mandibular 1st premolar
Which maxillary premolar has the shortest lingual cusp?
Maxillary 1st Premolar
Which of the teeth is most likely to have mesial root depression?
- Maxillary lateral incisor
- Maxillary Canine
- Maxillary 1st Premolar
- Maxillary 2nd Premolar
Maxillary 1st Premolar
Of the following teeth, which has a distal marginal ridge that is the smallest angle with the axis of the tooth?
- Maxillary First Premolar
- Maxillary Second Premolar
- Mandibular First Premolar
- Mandibular second Premolar
Mandibular 1st Premolar
Arrange the following teeth in descending order of which most likely to have two roots? 1. Maxillary First Premolar 2. Maxillary Second Premolar 3 Maxillary Central Incisors 4. Mandibular Canine
Maxillary First Premolar> Maxillary Second Premolar > Mandibular Canine > Maxillary Central Incisor
Which Premolar is often not a bicuspid?
Mandibular Second Premolar
Which of the anterior teeth show the greatest variation, like a peg-like tooth?
Maxillary Central Incisor
Which tooth surface is most likely to exhibit a continuous d relatively straight tour from the root to the crown?
Mesial Surface of Mandibular Canine
When looking at the Mandibular 1st Premolar, viewing which surface will permit observation of largest amount of occlusal surface?
Lingual (most variable cusp)
Which Premolar is most likely to have a lingual developmental groove?
Mandibular 2nd premolar
Which tooth is the widest in MD?
Maxillary Central Incisor
