Not necessarily. Each patient will have their own base level to electrical stimulus that must be determined at the time of testing. The base level for each patient can be determined by pulp testing similar teeth to the teeth in question. To confirm the diagnosis, a corresponding control tooth in the same arch should be tested. Molars should be matched to molars, premolars to premolars, cuspids to cuspids, and incisors to incisors. If this is not possible because teeth are
absent, endodontically treated, have full coverage or very large restorations a similar tooth in the opposite arch should be used.
