Mandibular second premolar
What is sometimes misdiagnosed as a premolar abscess?
The mental foramen
Why must you take came to avoid over filling an endodontic treatment on a mandibular second molar?
may impinge on the mental foramen
What are the three types of occlusal patterns that are seen in mand. second premolars?
(Y) = 5 lobes, 3 cusps
(H) = 4 lobes, 2 cusps
(U) = 4 lobes, 2 cusps, cental developmental groove appears crescent shaped
What is the most common type of mand. second premolar?
Y
Which tooth has a mesial marginal ridge that is distinctly shorter in length and less prominent in height than the distal marginal ridge?
Mand. first premolar
Where are the contacts of the mand. first premolar?
On the mesial or distal triangular fossae, slightly mesial or distal to the marginal ridges
The mandibular first premolar has a small, non-functioning _____ cusp.
Lingual
What does the masticatory function of the mandibular first premolar most resemble?
mand. canine
What are the four distinguishing characteristics of the Mand. premolars when compared to Max. premolars?
1. Proximally tilt lingually
2. Proximally outline is rhomboidal
3. Lingual cusps are smaller than buccal cusps
4. Occlusally crown is square
What is the proximal view of max. premolars?
Trapezoidal
What is the occlusal shape of max. premolars?
Rectangular
What is an important characteristic of mand. first premolars?
Occlusally the buccal lobe makes up the majority of the tooth.
One of the primary sections of formation in the development of the crown of the tooth. Cusp on post. teeth and mamelons and cingula on ant. teeth.
Lobes
What are the important root/pulp characteristics of the first Max. premolar?
1. Both root and pulp are kidney shaped
2. Only premolar with 2 roots and 2 canals
3. Buccal root/canal largest
Premolars are most _____ to do root canal treatments on because they are easy to perforate.
Difficult
Max. premolar roots occasionally penetrate the _____.
Antrum
How do you distinguish if a Max. first premolar is Rt./Lt.
There is a more pronounced mesial developmental groove.
Which premolar is the only one to have a mesial buccal cusp ridge that is longer thanits distal buccal cusp ridge?
Max. first premolar
What 2 teeth have pronounced cervical concavities on the surface of the crown?
Max. first premolar - mesial
Max. first molar - distal
What are the largest premolars?
Max. first premolars
What are the smallest premolars?
Mand. first premolars
What are the most closely vertically aligned of all teeth?
Max. and Mand. premolars
Where does a lingual cusp of a Max. second premolar pass through in a laterotrusive movement?
Through the facial embrasure between the second premolar and the first molar.
What is found on the mand. first premolar and is not present on either max. premolars?
Mesio-lingual developmental groove
What characteristics does the max. second premolar have compared to the max. first premolar?
One root - first has 2
More symmetrical and less angular
DBCR is longer than MBCR
Buccal/Lingual cusps are almost equal in height
Less prominent buccal ridge
Shorter central groove with minimal supplemental gooves
