Q

What is the identifying factor of the Maxillary 1st premolar? What does this identifying factor cause the root shape to look like?

A

it has a MesioMarginal Groove. This causes the root to indent on the mesial side and gives the root a kidney bean shape

25
Q

Which non molar tooth most frequently exhibits 3 roots?

A

the maxillary 1st premolar

26
Q

What is the relationship between the cusp heights of the maxillary 2nd premolar?

A

they are of equal height

27
Q

Which tooth is the most symmetrical posterior tooth?

A

the maxillary 2nd premolar

28
Q

Which tooth looks wrinkly?

A

the maxillary 2nd premolar

29
Q

Which tooth has snake eyes?

A

the mandibular 1st premolar

30
Q

Which tooth has a mesiolingual groove?

A

the mandibular 1s premolar

31
Q

Why can you see more of the occlusal table from the mesial side of the mandibular 1st premolar?

A

because the mesial marginal ridge is located more cervicaly than the distal marginal ridge

32
Q

Which posterior tooth is the smallest in the BL direction?

A

Mandibular 1st premolar

33
Q

What is the shape of the occlusal outline of the mandibular 1st premolar?

A

diamond

34
Q

What is the shape of the occlusal table of the mandibular 2nd premolar?

A

rectangle

35
Q

What is the shape of the crown of the Mandibular 2nd molar?

A

pentagonal

36
Q

Which tooth shows a Y, U, and H shape possibility? Which shape is most common?

A

the mandibular 2nd molar

the U shape is the most common

37
Q

How many lobes does the Mandibular 2nd molar develop from?

A

5

38
Q

The mandibular 2nd premolar in the Y shape has the same number of occlusal pits as which tooth?

A

maxillary 1st molar

39
Q

Which premolar has multiple lingual cusps, a lingual groove and a central fossa?

A

the mandibular 2nd premolar

40
Q

If you were congenitally missing a premolar, which one would it most likely be?

A

the mandibular 2nd premolar

41
Q

which tooth has a root that approximates the mental foramen?

A

the mandibular 2nd premolar

42
Q

What is the occlusal outline shape of the Maxillary 1st Molar?

A

rhomboidal

43
Q

Which angles are acute and which are obtuse on the Maxillary 1st molar occlusal outline?

A

the distobuccal and mesiolingual angles are obtuse

the mesiobuccal and distolingual angles are acute

44
Q

What are the sizes of the roots from biggest to smallest of the maxillary 1st molar?

A

45
Q

What are the lengths of the furcations of the the maxillary 1st molar from shortest to longest?

A

M<b></b>

46
Q

What are the 2 teeth that can cause problems for cleaning and matrix placement due to concavities?

A

the maxillary 1st molar - distal concavity

the maxillary 1st premolar - mesial developmental groove and root concavity

47
Q

Which cusps does the oblique ridge connect on the Maxillary 1st molar?

A

the distobuccal and the mesiolingual

48
Q

Which tooth has a cusp of carabellie and which cusp is it riding on?

A
