Background: Radiography is one of the useful tools employed in the dentistry for the purpose of diagnosis. Adverse health effects may occur due to clinically, un-indicated, avoidable repeat; un-optimized examinations and might require serious optimization. Film reject analysis is an important tool for identification of factors associated with suboptimal radiographic images and subsequent rectification. Hence; we planned this study to assess the reasons responsible for the rejection of radiographs through a repeat film analysis. Materials & methods: The present study included assessment of reasons responsible for repeat of radiographic films (both intra-oral and extra-oral). Collection of data of the repeat radiographic film of one year was done from the record room of the department and assessed. Radiographs showing all the anatomic details with optimum contrast and density and no distortion were considered as excellent. The rejected films were analyzed each day, and the reason for rejection and the type of examination were recorded. Information was recorded about the operator to allow classification into groups according to experience. All the data were recorded and analyzed. Results: Wrong angulations were prevalent in 27.2 percent of the cases. Prevalence percentage for error in radiography and wrong placement of radiographic films was 3.9 and 12.8 respectively. As far as machine error and error in positioning of tube head was 4.2 and 39.2 respectively. 5.2, 7.6 and 5.7 was the percentage prevalence of error in processing of radiographic film, movement of patient and other errors respectively. Conclusion: For the achieving higher improvements in the repeating rates of dental x rays, alterations in the teaching techniques should be done.
Key words: Radiograph, Repeat, X-ray
