Assessment of Intraoral Imaging Exposure Rates Among Dental Students: A Cross-Sectional Study on Radiographic Errors and Retake Factors
Pallavi Gadre
Abstract: A guiding principle of radiation safety is ensuring that radiation dosage is as low as possible while yielding the necessary diagnostic information. The aim of this study was to compare the number of radiographs taken in 'film - based' general dental practices, determine whether conventional radiography resulted in more or fewer radiographs, and analyze the reasons for any changesThe primary objective of this study was therefore to examine the prevalence of and reasons for re - exposure of intraoral images taken by third - and fourth - year dental students in a dental school clinic. All exposures were kept as low as reasonably achievable (ALARA). The total number of intraoral images taken by third - and fourth - year dental students, re - exposures, and error descriptions were extracted from patient clinical records for a four - month period. Out of a total of 9484 intra oral radiographs taken between July and October 2022, 1198 radiographs were repeated due to errors. The maximum number of repeated radiographs were Intra oral periapical radiographs, among those maximum number of patient re - exposures occurred due to cone cutting. Among bitewing radiographs, film misplacement was the most frequently repeating error. For occlusal radiograph, the most common artefact was improper vertical angulation. Errors in taking radiographs increase patient?s radiation exposure, and also waste time and money. Educational intervention can now be specifically designed to reduce the retake rate and radiation dose for future patients.
