Electric pulp testing (EPT) works on the premise that electrical stimuli cause an ionic change across the neural membrane, thereby inducing an action potential with a rapid hopping action at the nodes of Ranvier in myelinated nerves. A “tingling” sensation will be felt by the patient once the increasing voltage reaches the pain threshold, but this threshold level varies between patients and teeth, and is affected by factors such as individual age, emotional factors, pain perception, pain threshold, tooth surface conduction, and resistance, analgesic using, recent trauma, orthodontic treatment, etc
