Answer 2

Ectomesenchyme

Question 3

What type of tissue forms the enamel?

Answer 3

Ectoderm

Question 4

What is the dental lamina

Answer 4

Thickening of the Primary epithelial band which dips down for initial tooth development

Question 5

Difference between vestibular lamina and dental lamina?

Answer 5

Both thickening of the epithelium (dental will form tooth)

Question 6

Bud goes to school, graduates and gets a Cap, and then the Bells ring

Answer 6

Stages of tooth formation

Question 7

In the bud stage what induces growth in the mesenchyme?

Answer 7

Epithelium

Question 8

What is the enamel organ?

Answer 8

Ectomesenchyme cells on the inside of the bell/cap stage
Outer enamel epithelium
Inner enamel epithelium
Stratum intermedium
Stellate reticulum??

Question 9

Where is the dental papilla?

Answer 9

Under the cap/bell

Question 10

Where is the dental sac?

Answer 10

Sack under the cap stage (surrounds the dental papilla too)

Question 11

What is being induced during the cap stage and by what?

Answer 11

Mesenchyme induces the epithelium

Question 12

Where’s the enamel knot?

Answer 12

Inside the enamel organ on top of the cap (eventual cusp tip)

Question 13

What is the stellate reticulum?

Answer 13

Fills the middle of the enamel organ

Question 14

Where is the stratum intermedium?

Answer 14

Right on top of the Inner enamel epithelium(on the cap)

Question 15

What is the stratum intermedium?

Answer 15

helps with the enamel mineralization

Question 16

What is the cervical loop?

Answer 16

Where IEE and OEE meet (becomes the HERS)

Question 17

What does the Dental sac form?

Answer 17

Periodontium

Question 18

What does the dental papilla form?

Answer 18

Pulp

Odontoblasts

Question 19

What does the Inner enamel epithelium form?

Answer 19

Ameloblasts (enamel forming)

Question 20

What cells make the odontoblasts?

Answer 20

Dental Papilla

Question 21

What’s the direction of inductino for Enamel and Dentin?

Answer 21

Pre-ameloblasts induce Papilla to become Odontoblasts (dentin)
Dentin induce Pre-ameloblasts to become Ameloblasts (enamel)

Question 22

Wheres the tomes process? (PE)

Answer 22

Tail of ameloblast that shoots out enamel

Question 23

Where’s the tomes fiber?

Answer 23

Tail of the dentin

Question 24

What induces the Dental papilla outer cells to become root odontoblasts?

Answer 24

HERS

Question 25

What makes the cementoblasts?

Answer 25

The dental sac (after touching the root dentin)
