The aim of this study was to evaluate the clinical efficacy of four electronic apex locators i.e Dentaport ZX, Raypex 6, Propex pixi and I-Root in comparision with the standard radiographic technique.
A total of 20 patients diagnosed with apical periodontitis with no periapical lesions scheduled for root canal therapy were selected for the study and the working length of palatal canal were determined using the four apex locators and standard radiographic technique.
Statistical analysis was done using PRISM 5.0 Software. Intra-group comparison was done using repeated measures one way ANOVA with post-hoc tukey test and inter group comparision was done using Independent sample t test. No significant differences were detected between the apex locators (P=0.531).
The result in this study showed no significant difference among the groups, indicating they were as good as the radiographic method.
