Aim: The aim of the present study is to evaluate and to compare the accuracy of two electronic apex locators (EALs): DentaPort ZX and iPex, at a position 0.5 mm short of the apical foramen. Materials and Methods: Thirty single-rooted, mandibular premolar teeth were selected. Standard access cavities were prepared and the actual length (AL) was calculated. The samples were then embedded in alginate and the electronic measurements were determined and recorded. Results: The results obtained showed that in determining the root canal length with a tolerance level of ±0.5 mm, i.e., AL ± 0.5 mm, DentaPort ZX was accurate in 93.3% of the samples and iPex was accurate in 90% of the samples at a position 0.5 mm short of the apical foramen. Conclusion: A strong correlation was seen between the two electronic methods and AL and also in between the two EALs, showing the possibility of their use to measure the root canal length. No statistically significant difference was found between both the apex locators.
