Sample item

What is the main limitation of an electric pulp test?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. It tests sensory nerve response rather than true pulpal blood flow

Electric pulp testing assesses neural sensibility, which can be absent or altered despite residual pulpal blood flow, especially after trauma. Results are interpreted with history, examination, and other tests.

Option by option

  • A. It directly measures periodontal attachment

    Periodontal probing assesses attachment, not pulp sensibility.

  • B. It tests sensory nerve response rather than true pulpal blood flow (correct)

    Correct. Sensibility is not identical to vascular vitality.

  • C. It determines tooth color only

    Tooth color may be observed clinically but is not what the test measures.

  • D. It confirms root fracture in every case

    Root fractures require imaging and clinical correlation.
