Introduction: The aim of this study was to assess the radiographic technical quality of root canal therapy performed by three different groups of undergraduate, graduate and endodontic specialists conducted in the Jordan University of Science and Technology (JUST) Dental Teaching Center. Method and Material: The sample comprised of 320 subjects aged 18- 60 years old attended for endodontic treatments. Patients who had endodontic treatments were divided into three treatment groups according to their treatment providers (undergraduate students, graduate students and endodontic specialists). Periapical radiographic assessment sheet was attached to the patient’s file. This part included criteria for radiographic assessment for the quality of root canal filling. The following information were recorded, tooth type, quality of radiograph, taperness, length, and density of root canal filling, level of obturation in comparison to cement-enamel junction(CEJ), presence of apical periodontitis, location and size of apical periodontitis, presence of root resorption, presence of break in lamina dura, presence of widening of PDL space, presence of condensing apical periodontitis, presence of internal resorption, presence of missed canals, Presence of ledged canals, Presence of fractured instruments, presence of furcal lesions, pulpal diagnosis and restoration after endodontic treatment. Teeth were treated using at least three, long cones paralleling technique, radiographs (preoperative, working-length and postoperative) of a high quality that showed the entire length of the root and the periapical area. Two investigators using a magnifying lens and an X-ray viewer examined the radiographs independently. The results were compared and a final consensus was agreed. In case of disagreement, a third investigator was asked to read the radiograph and a final agreement was reached. Measurement was recorded and was taken as a caliber for periapical radiographs film reading. ...........
