Question 40 (part 2) · LDEK · Diagnosis
During pulp vitality testing with electric test, there is a risk of false negative result. The reason for such result may be:
1) improper isolation and inaccurate drying of the teeth before testing;
2) partial pulp necrosis;
3) pulp necrolysis;
4) immature teeth with nor formed apexes;
5) extensive mineral deposits in the canal.
Correct answer is:
2) partial pulp necrosis;
3) pulp necrolysis;
4) immature teeth with nor formed apexes;
5) extensive mineral deposits in the canal.
Correct answer is:
- A. 1,5.
- B. 2,3.
- C. 2,4,5.
- D. only 5.
- E. 1,4.
Hint
A false negative means a vital pulp fails to respond; think of situations where nerve fibres are immature, shielded or only partly preserved.
