Each tooth was radiographed twice with twodifferent radiographic systems; conventional & digital systems. The right-angleparalleling technique with film holders was used in both systems. The distancebetween the file tip and the center of radiographical apex from both imaging systemswas measured by two examiners and the mean of each two measurements wasrecorded, the data was collected and analyzed statistically by paired t- test.Results: The mean value of radiographic length reveals that there is a very smalldifference between the measurements of conventional radiographic system(0.8727mm) and those measurements of digital radiographic system (0.8367mm)when compared with the real length measurements (1mm). Paired t-test showsthat there is no significant difference (p < 0.05) was founded between the realmeasurements and the radiographic measurements are taken from both conventionaland digital systems. In conclusion both the conventional and digital imaging systemscan be used accurately for working length determination in an endodontic therapy.
