#MCQ 11 - Regarding Electric Pulp Test (EPT) for tooth vitality assessment, all of the following statements are true EXCEPT:
A. The objective is to stimulate a pulpal response by subjecting the tooth to an increasing degree of electric current
B. Any restorations in the tooth or the adjacent gingival tissue should not be contacted with the electrolyte or the electrode
C. The test is always performed on the tooth in question prior to testing on a control tooth
D. Gloves should not be worn while performing EPT because it may cause false negative responses

Answer:
C. The test is always performed on the tooth in question prior to testing on a control tooth

This statement is a false statement because, the test is always performed on a control tooth first, and then only on the tooth in question.

EPT checks the sensibility of a tooth by stimulating nerve endings with a low current and high potential difference in voltage. Although manufacturers of this device give normal reference values of current, the best way to check "normal/baseline" values is to use it on adjacent (nonpathological) teeth. This is then compared with the values obtained on the tooth being questioned. The EPT uses electrical excitation to stimulate the A-delta sensory fibers in the pulp.

Any restorations in the tooth or the adjacent gingival tissue should not be contacted with the electrolyte or the electrode because this may give a misleading response.

The electric Pulp test cannot be solely depended on for testing pulp vitality, results should be confirmed by other vitality tests like cold test or test cavity.

The most ideal way of performing a pulp sensibility test is a combination of cold test and Electric Pulp Test (EPT).
