Question 4

4

Which level of pulpal response is this: Inflammation and necrosis

Question 5

5

In a level 1 pulpal response, sclerotic dentin is formed by dentinal tubules becoming sclerosed and filled with what kind of dentin?

Question 6

5

Sclerotic dentin narrows the _____ of the tubule to decrease _____.

Question 7

7

This type of dentin is formed in the level 1 pulpal response and is slowly formed dentin that constricts the dimensions of the pulp chamber.

Question 8

8

What two things die in level 2 pulpal response to severe inflammation?

Question 9

8

Level 2 pulpal response can lead to differentiation of ______, which produces _____ on the pulpal wall.

Question 10

8

In level 2 pulpal response, if only the odontoblastic process dies, this results in empty dentinal tubules called _____.

Question 11

9

What is tertiary dentin caused by external stimulus that reactivates the dentinogenic activity of pre-existing odontoblasts?

Question 12

9

What is the teriary dentin that is generated by osteoblast-like reparative cells (odontoblast is dead).
