Knowledge of radiation protection among dental students in a medical college, Nepal

Introduction: Radiation protection is a core component of radiographic practice and provides optimal patient safety and control of radiation hazards. In this study, we aim to determine the knowledge of radiation protection among dental students in a medical college, in Nepal.Materials and methods: Bachelor’s degree dental final year students studying at Gandaki Medical College (GMC), Pokhara, Nepal were included in this study. A questionnaire survey tool was developed by consulting with two lecturers of medical imaging technology who have more than 10 years of experience. 10 multiple-choice questions (MCQs) were handed to each participant. Each correct answer was given a “1” score and each incorrect answer was given a “0” score. There were no negative markings. The knowledge score was categorized as <60 % inadequate, 60–80 % adequate, and 80–100% excellent. Data were coded and analyzed in IBM SPSS statistics, version 28, Chicago, United States. The normality of the data was checked by using the Shapiro-Wilk test. The equality of variance was assessed by Levene’s test. The p-value was set at a 5% level of significance. Two sample ttest was applied since the data followed a normal distribution. Results: A total of 16 dental students, 5 males, and 11 females, 22.060.77 mean age, 20-23 age range were included in this study. Participants did not have prior training in radiation protection. The mean knowledge of radiation protection score was 52.5%, 5.251.52, with a maximum score of 8 and a minimum 3 of which was inadequate. There was a statistically significant difference in knowledge according to gender, p=0.01, t(14)=2.92. The mean response was 60% (adequate) for 21-year-old participants and was inadequate at other ages.Conclusion: The knowledge of radiation protection should be improved among dental students. Adequate course materials and training should be included in their curriculum. Radiation protection national regulations should be implemented as soon as possible
