Abstract

Introduction: The purpose of this study was to compare the accuracy of different generations of electrical
apex locators (EALs) using different measuring protocols. The accuracy of E-PEX PRO (Eighteeth,
Changzhou, China) as newly introduced device, Root ZX (J Morita Corp, Tokyo, Japan), and iPex (NSK,
Tochigi, Japan) EALs were evaluated.
Methods: In this study thirty extracted human permanent single rooted premolar were used. The working
length was determined with #15 K-file, then by one of the three EALs, first by introducing the file into the
canal until the EAL reads 0.0 then retracting the file until it reads +1.0, second by proceeding the file until the
EAL reads +1.0. The data were analyzed using One-way repeated measure ANOVA test at P value of (0.05).
Results: No statistically significant differences were found between the three EALs at either measuring
protocol
Conclusions: Under the in-vitro conditions of the current study, all tested EALs were accurate in estimating
working length.
