Waldent Electric Pulp Tester
It is a device to examine the vitality of dental pulp using the electrical stimulation. During the pulp test, the current stimulates intradental nerve, and give severe pain to patients.
Some studies were accompanied to measure the responses of subjects by stimulating over the sensory threshold to determine whether the nerve of pulp in the tooth remains alive. So it can accurately read the pulp’s vitality in a very highly efficient way.

This test is conducted under a medium like toothpaste on dried tooth.
Place the probe tip flat on the tooth close to the pulp horn ( labial/ Buccal surface)
