Question 124 · LDEK · Vital pulp therapy
Mixing calcium hydroxide with physiological saline to form a paste and then applying it to the exposed pulp in a sterile environment results in:
1) a mild inflammatory reaction of tissues lying underneath the ones being in contact with the paste;
2) at first the necrosis of the pulp tissues contacting the paste and then the healing into a fully formed, healthy vital pulp;
3) necrosis of the pulp tissues contacting the paste, then a demarcation zone rich in collagen forms, and eventually a mineralized barrier;
4) eventually a mineralized barrier called the dentin bridge;
5) either general acute pulpitis or necrosis.
The correct answer is:
2) at first the necrosis of the pulp tissues contacting the paste and then the healing into a fully formed, healthy vital pulp;
3) necrosis of the pulp tissues contacting the paste, then a demarcation zone rich in collagen forms, and eventually a mineralized barrier;
4) eventually a mineralized barrier called the dentin bridge;
5) either general acute pulpitis or necrosis.
The correct answer is:
- A. 1,2.
- B. 1,3,4.
- C. 2,5.
- D. 3,4,5.
- E. 1,4,5.
Hint
Recall how the very high pH of calcium hydroxide affects the pulp surface it touches and what forms beneath that zone over the following weeks.
