24
Q

which teeth have 7-8 pulp horns

A

maxillary 11s

25
Q

do mandibular cheek teeth have infundibulum

A

no

26
Q

2 categories of enamel

A

peripheral and infundibular

27
Q

3 types of enamel

A

1 - cheek teeth - wear resistance
2 - incisors - shear forces
3- less prominent, transitional

28
Q

what is dentin for

A

tensile strength, compressibility
between enamel - form laminated structure
crack stoppers

29
Q

what creates the irregular occlusal surface

A

dentin and cementum

30
Q

types of primary dentin

A

intratubular and intertubular

31
Q

types of secondary dentin

A

regular - continuous with primary
irregular - laid down from attrition of occlusal surface, prevents pulpar exposure

32
Q

what is tertiary dentin

A

laid down locally in response to noxious stimuli

33
Q

what is in pulp

A

connective tissue skeleton, vasculature, lymphatics, nerves

34
Q

when do roots develop

A

by 2 yrs

35
Q

which is the softest dental tissue

A

cementum

36
Q

major structural component of clinical crown

A

cementum

37
Q

what does cementum do

A

reparative function
deposited rapidly in response to stimuli

38
Q

brachygnathism

A

short mandible
congenital

39
Q

prognathism

A

protruding jaw

40
Q

when do canines erupt

A

4-6 yrs

41
Q

canine teeth are

A

brachydont

42
Q

is it common to have mandibular wolf teeth

A

no

43
Q

when do wolf teeth erupt

A

6-18 mo

44
Q

how to remove wolf teeth

A

sedate, block, elevate, gently

45
Q

how to age incisors

A

eruption times, shape, occlusal surface, glavaynes groove, dental stars

46

A

deciduous
01 - 6d
02 - 6 wk
03 - 6 mo
permanent
01 - 2.5 yr
02 - 3.5 yr
03 - 4.5 yr
