What are the tooth numbers for the Maxillary premolars ?
What are the tooth numbers for the Mandibular Premolars
4 and 5 - 11 and 12
20 and 21 - 28 and 29
Indicate the following on this picture of a Premolar ?
What do the Premolars do ? What process do they supplement for molars ?
They are for piercing and they supplement grinding for the Molars.
How many developmental lobes do you usually see on a premolar ? and what are there location?
How many cusps does a premolar usually have ? and what is there position ?
Do premolars possess an occlusal surface ?
Typically, four developmental lobes:–3 buccal, 1 lingual
Typically, two cusp facial and lingual
What is unique about the Maxillary Premolars ?
Which of the two is larger ?
Which way are the crowns wider ? F-L or M-D
First and second are more similar than mandibular premolar
First slightly larger than second
from the facial view where is the cusp tip located relative to the midline ?
Which is longer , the MB cusp ridge or the DB cusp ridge ?
Cusp tip located just distal to midline of root
The MB cusp ridge is longer
Which way the the lingual cusp of the Maxillary 1st premolar leaning towards ? Mesial or distal
What are two very special things about the Maxillary 1st premolar ?
- Mesial marginal groove visible
- •Mesial concavity from root trunk to cervical portion of crown*
On the Maxillary first premolar which way is the lingual cusp offset to ______ ?
Is the lingual narrower M-D than facial ?
Is the lingual cusp or shorter or taller ?
Is the lingual cusp of the first premolar,the smallest in the mouth ?
In the First premolar is there a mesial concavity from the root trunk to cervical portion of crown?
On the First premolar the Mesial marginal ridge shorter than distal marginal ridge ? T or F
Are the M-D pits well separated ?
What are the three Type forms ?
- Type 1 - No bifurcation
- Type 2- Bifurcated
- Type 3- Partial Bifurcation
How do you tell the difference between a right and left Maxillary 1st premolar ?
•Lingual cusp tipped mesially*
•Mesial marginal groove
•MB cusp ridge longer than DB*
Is the crown bigger on the First or Second Mailllary Premolar ?
Indicate which tooth is rounded and which angular ?
Which one has more equal cusp sizes ?
1st is more angular and the 2nd is more rounded
the second premolar
out of the first and second maxillary premolar which one has a marginal grove and a mesial concavity ?
Which has closer MD pits ?
Which has more supplemental groves
The 2nd premolar has closer MD pits
On the second maxillary premolar , which cusp slope is shorter , MB or DB ?
