Most consistent diagnosis?
Tooth tests NEGATIVE to cold, with swelling and pain on percussion.
Show answer and explanation
Correct answer: A. Pulp necrosis with apical periodontitis/abscess
Negative cold = necrosis; percussion pain + swelling = symptomatic apical periodontitis/abscess.
- A. Correct. No response to cold = non-vital (necrotic) pulp; percussion pain + swelling = apical periodontitis/abscess.
- B. Irreversible pulpitis is still vital and would respond to cold — inconsistent with a negative cold test.
