Abstract

Introduction: Dental radiography has a major role in diagnosis of oral and dental diseases. Different technical methods are used to obtain high quality image in radiography and reduce X-Ray exposure in the patients. In this research modified techniques for periapical intraoral radiography with parallel technique by using XCP and Snap-A-Ray film holders had been used to overcome technical errors. Materials and Methods: With the use of XCP and Snap-A-Ray film holders, 96 parallel periapical intraoral radiographs were taken from 96 patients who were reffered to the radiology department of Isfahan dental school with the same condition of operation such as voltage (70 kvp), Amp(8 mA). The type of radiography films was E speed. From 96 radiographs, 6 of them were included in the pilot study and 90 radiographs were processed automatically (processor) in the same condition and after observation by the radiologist, the reports were written in the checklist Results: Evaluation of intraoral radiographs obtained by use of Snap-A-Ray film holder, showed technical errors of cone cutting (26.7), displacement (15.6), foreshortening (13.3), elongation (8.9) and overlapping (2.2) whereas none of these technical errors were observed in intraoral radiographs obtained by use of XCP film holders. Discussion & Conclusion: Totally the XCP film holders are easier to use and image quality of radiographs are better than those of Snap-A-Ray film holders. Regarding to the absence of technical errors and better image quality using XCP film holders, these film holders are preferrred which prevents repetition of radiography and reduces patient x- ray exposure dosage.
