Mix of all

Question 1

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

Answer 1

Maxillary First Premolar

Question 2

Which molar has a non-functional cusp?

Answer 2

Mandibular First Molar

Question 3

Of all premolars, which is the most symmetrical from facial to lingual when looking at an occlusal view?

Answer 3

Maxillary Second Premolar (with mandibular central incisor)

Question 4

Which premolar is the only one to have a lingual height of contour in the occlusal 3rd?

Answer 4

Mandibular 2nd Premolar

Question 5

On a maxillary premolar, what proximal view allows you to see the most occlusal surface

Answer 5

Distal

Question 6

In which tooth does the buccal cusp take up 2/3 of the occlusal surface from an occlusal view?

Answer 6

Mandibular 1st premolar

Question 7

Which has the greater O-C dimension, maxillary 1st premolars or maxillary 2nd premolars?

Answer 7

Maxillary 1st premolar

Question 8

From which proximal view are all 3 cusp tips visible on a mandibular 2nd premolar and why?

Answer 8

Distal view; b/c the distal marginal ridge is more cervical than the mesial marginal ridge and the ML cusp > DL cusp

Question 9

Where would you find a prominent mesial concavity?

Answer 9

Maxillary 1st Premolar

Question 10

From an occlusal view, which tooth may have a slight divergence lingually?

Answer 10

Mandibular 2nd premolar

Question 11

From an occlusal view, which tooth has a divergence lingually?

Answer 11

Mandibular 1st premolar

Question 12

What are the only succedaneous teeth to NOT replace the same type of tooth?

Answer 12

Premolars (they replace primary molars→NO primary premolars)

Question 13

On which tooth is the lingual cusp that is most variable in size of any premolar?

Answer 13

Mandibular 1st premolar

Question 14

Which maxillary premolar has the shortest lingual cusp?

Answer 14

Maxillary 1st Premolar

Question 15

Which of the teeth is most likely to have mesial root depression?

• • Maxillary lateral incisor
• • Maxillary Canine
• • Maxillary 1st Premolar
• • Maxillary 2nd Premolar

Answer 15

Maxillary 1st Premolar

Question 16

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

Answer 16

Mandibular 1st Premolar

Question 17

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

Answer 17

Maxillary First Premolar> Maxillary Second Premolar > Mandibular Canine > Maxillary Central Incisor

Question 18

Which Premolar is often not a bicuspid?

Answer 18

Mandibular Second Premolar

Question 19

Which of the anterior teeth show the greatest variation, like a peg-like tooth?

Answer 19

Maxillary Central Incisor

Question 20

Which tooth surface is most likely to exhibit a continuous d relatively straight tour from the root to the crown?

Answer 20

Mesial Surface of Mandibular Canine

Question 21

When looking at the Mandibular 1st Premolar, viewing which surface will permit observation of largest amount of occlusal surface?

Answer 21

Lingual (most variable cusp)

Question 22

Which Premolar is most likely to have a lingual developmental groove?

Answer 22

Mandibular 2nd premolar

Question 23

Which tooth is the widest in MD?

Answer 23

Maxillary Central Incisor
