Correct answer: C — Electric pulp test (EPT)

The electric pulp test (EPT) applies a gradually increasing electrical current to the labial/buccal surface of the tooth (through electrode paste for conductivity) until the patient perceives a tingling or warming sensation. A positive response (sensation at a given reading) indicates that the pulp nerve fibres are functional — it does not measure pulp blood flow (vitality). False positives (response from a necrotic tooth) can occur from stimulation of adjacent vital tissues. False negatives can occur in traumatised, recently erupted, or heavily restored teeth.
