INTRODUCTION:
The history of endodontics begins in the 17th century. Research has brought numerous advances and developments and now endodontic therapy is regarded as a specialized procedure which not only requires complete knowledge of the subject but an appropriate armamentarium as well. Irrespective of the reasons of undergoing the root canal treatment, 1 accurate working length determination ensures successful root canal treatment, reduction in chance of insufficient cleaning of the canal or of damaging the periapical tissues from over instrumentation. Traditional methods for establishing working length such as radiographs, anatomical averages of canal length, tactile sensation and moisture on a paper point have their limitations. Radiographs, which are always regarded as a two dimensional image of a three dimensional structure are not only technique sensitive 2, 3 but are also subjected to distortion and magnification. Even amongst experienced clinicians, the use of anatomical averages and tactile sensation has proved to be unreliable and are subjected to marked intra-subject differences. The development of electronic apex locators (EALs) has helped in making the assessment of working length more accurate and predictable. Use of EALs in combination with radiographs allow an accurate working length determination.4, 5 Dentaport ZX (J. Morita Corp, Tokyo, Japan),has a proven accuracy 6 in working length determination, even in presence of different electrolytes, blood and irrigant solutions7, 8,...
