An evaluation of media used in electric pulp testing

Electric Pulp Tester Conductance Through Various Interface Media

“…Some of these conduction differences were found to be statistically significant. These findings are in contrast to those of Martin et al (6) and Cooley and Robison (7), who found that the type of medium used to couple the probe of the electric pulp tester to the tooth surface was not significant. One possibility for this difference could be the limited number of media they used even though they did include water as a media.…”

“…This being true, liquid interface media are not recommended when using EPTs. Even though liquid media are not recommended for use with EPTs, they were still included in this study as previous authors have also tested them (6,7) and we wanted to test some readily available media that are found in dental offices.…”

“…Martin et al (6) concluded that there were no appreciable differences in either the voltage or the potential difference transmitted by the tester using various media. Additionally, EPT manufacturers differ on their recommendations for media, ranging from toothpaste to electrode gel.…”

Effects of conducting media and gender on an electric pulp test

“…The available evidence shows comparable efficacies of some interface media in the ability to transmit the electric current through tooth to the pulp both in extracted teeth (Martin et al . , Cooley & Robinson ) and clinical study (Michaelson et al . ).…”

Electric pulp testing: a review

“…1975, Cooley & Robison 1980). A laboratory study by Martin et al. (1969) concluded that the interface medium made no appreciable difference to either the voltage or the electric current transmitted.…”
