Dental pulp tests are investigations that offer valuable diagnostic and treatment planning information to the dental clinician. EPT is a sensibility test that can be easily performed in clinical practice. Current study is to find the best conducting substance among readily available water-based gels and gel-based tooth pastes to evaluate the efficacy of electric pulp tester.

The study will be performed on dental students with written informed constant. The sample size of study is 100. There will two main groups of conductor materials used in the study: water-based gels (fluoride gel, electrode gel and chlorohexidine gluconate) and gel-based toothpastes (Colgate and Dentonic Ultrawhitening gel). All groups will be randomly applied to the same patient at a single visit. Two measurements will be recorded for each material and the average value of the two measurements will used. Then, the measurements will record, and a comparison will be made between different conductors.
