Assessment of Quality of Radiograph Taken by Undergraduate Students in Paediatric Dentistry Clinic: An Institutional Study

Abstract

Background: Dental radiograph acts as an adjunct to the clinical examination that aids the dentist to evaluate and definitively diagnose many oral diseases and conditions. Bitewings and periapical radiographs are the two intraoral radiographs that are commonly used in paediatric dental clinic. Aim: To assess the quality, justification and reporting of intraoral radiographs taken by the undergraduates dental students in the paediatric dental clinic. Methods: The folder of 154 paediatric dental patient treated by the 4 th and 5 th year undergraduates dental students during the 2018/19 academic session were retrieved retrospectively from the record unit. The quality of the radiograph was graded as grade 1, grade 2 or grade 3 by two calibrated examiners based on the National Radiological Protection Board (NRPB) criteria. The justification and reporting of the radiographs were also assessed. Data were analysed using the Statistical Package for the Social Sciences (SPSS) Version 27 software (IBM, Armonk, NY, USA). Results: A total of 108 radiographs were available for assessment, which consist of 55 bitewings and 53 periapical radiographs. 6.5%, 45.4% and 48.2% of the radiographs taken were graded as grade 1, grade 2 and grade 3 respectively. The justification for radiographical investigation were stated in 88.9% of the radiographs, while only 11.1% did not justify. Investigating interproximal caries and periapical status of the teeth were the most common justification for taking bitewings and periapical radiographs respectively. Only 5.6% of the radiographic findings were reported either in the examination and diagnosis form or in the patients' folder, while the remaining 94.44% radiographs were not reported. Conclusion: Majority of the undergraduate dental students took poor quality radiographs which renders the radiograph to be diagnostically unacceptable and failed to record the reporting in the patient's folder. However, majority of the dental students did justify the needs for the radiographic investigation.

Comparative study of 360° virtual reality and traditional two-dimensional video in nonface-to-face dental radiology classes: focusing on learning satisfaction and self-efficacy

“…That is, the learner does not directly operate in an intraoral dental X-ray unit. Oral radiographic images that contain errors cannot precisely validate the patient’s condition, thus affecting accurate diagnosis [ 54 ]. Obtaining intraoral radiographic images that accurately depict the patient’s oral condition is largely dependent on the skills of the DR operator.…”
