1
Q

what is the third stage of odontogenesis?

A

Cap Stage

2
Q

Cap Stage occurs?

A

b/w the 9th and 10th week in utero

3
Q

describe the proliferation in the cap stage

A
tremendous growth 
(proliferation is going to continue)
4
Q

not only does proliferation characterize this stage, but various levels of?

A

differentiation

5
Q

what are the more specific processes of differentiation in the cap stage?

A
  1. cytodifferentiation
  2. histodifferentiation
  3. morphogenesis
6
Q

what is morphogenesis bringing about?

A

the actual SHAPE of something

7
Q

what is NEW in the cap stage?

A

DIFFERENTIATION will START!!!!!

8
Q

THE CAP STAGE IS KNOWN FOR?

A

DIFFERENTIATION!!!!!

VERY IMPORTANT

9
Q

describe the enamel knot formation

A

Inner most outline determines the future dental shape

and origin is Ectodermal

10
Q

in the cap stage there is also the formation of?

A

glycosaminoglycans: (hydrophilic)

11
Q

glycosaminoglycans is known as?

A

“GAGS”

12
Q

what does the “GAGS” do in the cap stage?

A

they are used to attract water to the developing tooth

13
Q

where are the “GAGS” location?

A

desomosome junctions

14
Q

what is the main thing that the cap stage is known for?

A

Morphogenesis

15
Q

the enamel knot in the cap stage will become?

A

the enamel organ

16
Q

the enamel organ in the cap stage will become?

A

the enamel

17
Q

the inner mass of ectomesenchyme in the cap stage is now considered the?

A

dental papilla

18
Q

the dental papilla in the cap stage will produce the future?

A

dentin and pulp

19
Q

the remaining ectomesenchyme surrounding the outside of the cap or enamel organ condenses into the?

A

dental sac

20
Q

the dental sac is going to contribute to the structures of?

A

cementum
periodontal ligament (PDL)
alveolar bone

21
Q

the enamel organ, dental papilla, and dental sac all together is called?

A

the tooth germ

22
Q

the enamel organ is what in origin?

A

ectodermal

23
Q

the dental papilla and dental sac is what in origin?

A

ectomesenchyme (mesoderm)

24
Q

the successive dental lamina adjacent will become?

A

the permanent tooth bud!

25
Q

the basement membrane in the cap stage is b/w?

A

b/w the enamel organ and the dental papilla

26
Q

the successional dental lamina of the anterior will develop?

A

lingually

27
Q

the successional dental lamina of the premolars develop where?

A

in furcas (furcations) of molars

28
Q

the successional dental lamina of the molars develop where?

A

distal from the premolars
