Abstract Purpose This research was to evaluate the Working Length of the root canal, in the presence of different Irrigants Using Digital Radiography, IOPAX-Ray and Electronic Apex Locator. Method Access openings were made in all the Sixty (60), extracted teeth and the pulp was extirpated. After this an endodontic file was placed inside the canal unless visible from the Apical Foramina with naked eyes. The file was then pulled back approximately 0.5mm and an IOPA radiograph followed by RVG was taken. For the measurements with apex locator, first the apical foramina were blocked using the molding wax. Water was then injected into the root canal of the tooth for the apex locator measurement, as it cannot record the measurements in dry canals, subsequently in the presence of various irrigants. Results While comparing different diagnostic aids with the control group in Central Incisors, Canines and Premolars, Mean value of absolute change were observed to be not statistically significant. CONCLUSION- The accuracy of the Electronic Apex Locator was found to be optimum. However, a combination of methods can increase the accuracy of Working Length Determination.
