*rarely internal tooth resorption

Question 10

What are three ways a restoration immediately affects the pulp?

Answer 10

1-Thermal (bur heat)
2-Mechanical (cut dentin)
3-Chemical (restorative materials)

Question 11

What causes pulp insult years after a restoration is placed?

Answer 11

Bacterial microleakage

Question 12

What are three examples of physical trauma to the pulp?

Answer 12

1-Severance of the neurovascular supply
2-Concussive effects to the pulp
3-Direct pulp exposure

Question 13

What are 3 responses of the pulp to physical trauma?

Answer 13

1-Discoloration- heme breakdown causes darkening of the tooth
2-Resorptive defects
3-Healing, or death

Question 14

What are two things endodontic treatment accomplishes?

Answer 14

1-Eliminate infection in the dentin-pulp complex

2-Maintain tooth/teeth within the oral complex

Question 15

What about the tooth vascular supply makes it be able to get to a point that it cannot heal anymore?

Answer 15

It has a terminal end blood supply, does not have collateral blood supply
