Abstract

Background:  Background: The electric pulp tester has been used as a diagnostic modality to discriminate the periapical diseases of endodontic basis from various other pathological articles with similar radiographic findings. The results can be false-positive or false-negative amongst 10 to 20% of the cases. Electric pulp tester producers differ on their references of media, ranging between toothpaste to gel based electronic media. The present study was conducted with the aim to determine the conductance of the electric pulp tester through different conducting media invitro. Materials and methods: Freshly extracted premolars were used for the study. Pulp chamber was exposed and cathode was put into the pulpal tissues. The voltage at the cathode was recorded. The readings were recorded on the voltmeter when the digital display showed 40. Average of 5 readings was obtained in all the cases Results: All the toothpastes showed similar conductance of around 0.6. K-Y brand lubricating jelly, media recommended by the manufacturer showed a conductance of 1.3. Conclusion: Therefore, it is crucial to determine the sort of interface while testing for pulpal obliteration. A weak conducting material may result in false positive results.
