It is used to diagnose pulpal health of the dental nerve and vasculature inside the pulp chamber and root canals of a tooth. These are useful and essential diagnostic aids in endodontics.
- Tests pulp vitality of an injured/non injured tooth.
- A gentle, pulsed stimulus begins to increase.
- Convenient to operate.
- Extremely economical.
- Electric pulp testing (EPT) is done by placing a tester on the to-be-tested tooth along with a drop of conducting paste.
- Usually the patient’s saliva or toothpaste suffices as a conductor of electricity.
- The electric current is gradually increased until the patient signals a sensation, which consists of clicking or buzzing in the tooth.
- The test is repeated on neighboring teeth and often on the corresponding contralateral tooth.
- The lowest perceptible current is recorded for each tooth.
