The purpose of this study was to evaluate the accuracy of Root ZX and Sybron Mini in determining the working length
using 2.5% Sodium Hypochlorite, 2% Chlorhexidine gel and saline. Donnelly¡¯s gelatin technique was used for measuring
twenty extracted human teeth. Electronic working length was measured at the display 0.5 and 0.0 level of each electronic
apex locator using a digital caliper to the nearest 0.01 mm. Each measurement was repeated for each different irrigants.
Accuracy of Sybron Mini was not significantly different from the Root ZX in the three different irrigants, and there was
no significant difference in the accuracy of electronic apex locators among the irrigants when used as recommended by
manufacturer (measuring electronic working length at 0.0 level of Sybron Mini and at 0.5 level of Root ZX).
