Ideal Electrode Placement Site of Electric Pulp Tester: A Clinical Study

Abstract

Introduction: Endodontic diagnosis is the essential aid in deciding the treatment plan though it has limitations and shortcomings. Electric pulp testers are widely used for endodontic diagnosis. Such testing requires the tip of electrode to be in optimal position on the surface of the tooth. Aim: The aim of the study is to determine the ideal electrode placement site of electric pulp tester for the mandibular premolars. Material and Methods: Electric pulp tester was used to assess the response of the tooth. A sample size of 60mandibular premolar teeth were included in the study. The electrode tip of electric pulp tester was placed on different sites on the buccal aspect of the tooth. The response of the tooth was evaluated. Results: The lowest response for mandibular premolar was observed to be on the tip of the buccal cusp. The threshold level was said to increase from the buccal cusp tip to middle third and cervical third. It was also concluded that there was no significant difference found between male and female and also with respect to age in response to level of perception of threshold. Conclusion: It is necessary to place the electrode tip of the electric pulp tester at the appropriate site for the accurate diagnosis.
