Working length of root

EAL Group: Working length was measured using the Root ZX apex locator (J. Morita Corp., Kyoto, Japan), following the manufacturer's instructions. A #15 K-file was connected to the device and advanced until the display indicated "APEX," confirming the location beyond the apical foramen. DR Group: Working length was determined using a #15 K-file inserted 1 mm short of the estimated radiographic apex. A digital periapical radiograph was taken, and the working length was adjusted accordingly. Repeated radiographs were obtained until the file tip was 1 mm short of the radiographic apex.
