The investigate of the prevalence of Bitewing and Periapical radiography errors prepared in the radiology department of the faculty of dentistry birjand university of medical sciences in 2017-2018

With showing an error in the intra-oral radiographic images, dentist diagnosis may be affected by the occurrence, and the patients treatment plan can be problematic in these cases. The present study aimed to determine the prevalence rate of Bitewing and Periapical radiography errors prepared in the radiology department of the faculty of dentistry birjand university of medical sciences.
 

In a descriptive cross-sectional study, 3761 Bitewing and Periapical radiography prepared by 8th and 9th-semester dental students in 2017-2018 were selected and evaluated. by viewing radiography, common radiographic technical errors, as well as repeat or non-repeat radiographs in them, were determined and reported. Finally, the frequency and percentage of radiographic errors were analyzed using the SPSS software (version 23) and Chi-Square test. Significance level (p = 0.05) was considered.

Common radiographic errors were incorrect filmed placement 20.71%, cone-cut 20.10% Elongation 10.70 % and the repetition rate of the radiographs was %30, respectively. There was a significant relationship between the type of error and the students' semester(p:0.001). The frequency of error in periapical radiography was more than of the bitewing radiograph.

Based on the results of the study population, the most radiographic errors included film insertion errors and cone cut and these two errors were the most frequent cause of repeate radiographs that emphasize required the provision of specific training for the prevention of these errors.
