A pulp test gives a NEGATIVE response but the tooth is later confirmed to be vital. (Same concept restated.) This result is best classified as a:

Correct answer: A. False negative

  • B. A false positive is a non-vital tooth that tests positive.
  • C. A true negative would be a correctly identified non-vital tooth.
  • D. 'Sensitivity error' is not a standard classification of an individual test result.
