Dental radiography plays an important role in the diagnosis of the mouth and teeth diseases. Different methods are used for improving the quality of radiographic images of patient and for limiting the contact with ionization radiation. The aim of this study is to evaluate the frequency of radiographic errors of periapical. In this study, a number of 2292 periapical radiographic films taken by bisector method were examined to determine the frequency of the errors. The Xray films were produced by dental students from patients then they were classified based on the type of the error. Among the 2292 X-ray radiography films in this work, a number of 296 had errors (12.9%), 4 cases of the greatest errors in this study were Elongation (19.6 %), improper placement of films (18.9 % ), Cone cut (14.6%) and cut of the apex in the radiography (13.9 %). Considering the importance of reducing the risk of exposure to ionizing radiation, as well as decreasing the time and cost, organizing appropriate plans for academic and practical training of dental students is proposed to reduce the radiography errors.
