Q

What is the most unique feature of a maxillary canine from a facial view?

A

concavity on the DF cervical 1/3 (HUGE CAVITY AREA)

21
Q

Which tooth is more likely to have 1 or NO pulp horns?

A

Mandibular Incisiors (RATS! I put max incisors)

22
Q

T/F: At 14 weeks in utero, hard tissue begins forming in the central incisor, and sometimes the lateral incisor

A

True

23
Q

T/F: At 55 - 56 days in utero, hard tissue begins forming in the central incisor

A

FALSE- 56 days is 8 weeks. QUICK MATH tells me this is Way to SOON

24

T/F: By 16 weeks in utero, hard tissue begins forming in in the first molar

A

True

25
Q

T/F: At 42 - 48 days in utero, the dental lamina forms

A

True

26
Q

T/F: By 18 weeks in utero, hard tissue begins forming in the second molar

A

True

27
Q

Is Chronic Periodontitis a symptom of pathogenic occlusion?

A

Hell NAW

28
Q

The Bennett Angle is formed between between _______ and _________ lines on the pantographic tracing

A

protrusive and NW lines…how did i get this wrong?? OH, I put protrusive and NW condyler paths, not PANTOGRAPHIC TRACING (WTF?)

29
Q

The stylomandibular ligament limits excessive _______ movement of the mandible

A

protrusive

30
Q

What kind of a role does the sphenomandibular ligament play in limiting mandibular movement?

A

A MINIMAL role

31
Q

The roots of primary anterior teeth are comparatively ________ and ________ when matched against the permanent dentition.

A

Narrower, longer

32
Q

What is the shape of the functional form of Max 2nd PMs?

A

Oval

33
Q

Movement of the mandible is characterized by the position of the _________ in ______________.

A

condyle in the GLENIOD FOSSA (not the articular eminence)

34
Q

In a sagittal plane, what is the THICKEST section of the articular disc?

A

Posterior border

35
Q

Permanent MANDIBULAR canines usually erupt at age:

A

9-10 years

36
Q

The dentition of a normally developed 7 year old has ____ primary teeth and ___ permanent teeth.

A

18 primary (only lost the central’s)….6 permanent (centrals in, 1st molars in)

37
Q

What is the shape of the Mand 1st PM from the FACIAL aspect?

A

pentagonal (not diamond, which is occlusal view!)

38
Q

Does normal mastication INFLUENCE the alignment of teeth?

A

NO!!! go figure!

39
Q

T/F: In the horizontal plane, the contour of the glenoid fossa’s posterior wall (working side) dictates the placement of tooth grooves in the working side

A

True

40
Q

T/F: Immediate side shift is movement into the position toward the medial fossa wall on the working side

A

True

41
Q

T/F: The working groove is usually at a right angle to the central groove, while the nonworking groove is usually oriented at an oblique angle to the central groove

A

True

42
Q

T/F: The Bennett Angle is another name for the Bennett Movement

A

False!

43
Q

T/F: In the horizontal plane, the contour of the glenoid fossa’s medial wall (non­working side) determines working, nonworking and central groove position and width

A

True

44
Q

The permanent anterior tooth whose pulp chamber has the GREATEST FL measurement is the????

A

MAXILLARY CANINE

45
Q

T/F: Coordinated chewing operates at the open end of a chewing stroke when muscle elevator and muscle opener actions overlap

A

True

46
Q

T/F: The crushing stage requires 3-4 strokes and the tituration (grinding) stage averages 20 strokes

A

True

47
Q

T/F: The adaptive arc of closure and the touch-open reflexes both occur at the expense of muscles and joints

A

True

48
Q

T/F: During mastication, the food bolus is normally positioned bilaterally on both the working and non-working sides

A

False

49
Q
