Knowledge and Attitude toward the Cone Beam Computed Tomography among Dental Students – A Cross Sectional Questionnaire Based Study

Abstract

Background: Cone Beam Computed Tomography (CBCT) has transformed dental imaging by providing three-dimensional visualization with increased accuracy and CBCT provides three-dimensional visualization with lower radiation doses than conventional medical CT. Adequate awareness and a good attitude toward CBCT are necessary for its effective and responsible application in a clinical setting. This study sought to evaluate dental students' knowledge and attitudes about using CBCT. Methods: A cross-sectional descriptive study was conducted with undergraduate dental students, using a structured self-administered questionnaire. The survey consisted of questions about demographic data, indications for CBCT, awareness of radiation safety, and attitudes toward CBCT in the clinical setting. Descriptive statistics were used to summarize the data and chi-square tests were conducted to identify associations between academic level, knowledge, or attitude scores. Results: A total of 230 undergraduate dental students and interns participated in this study. The majority of students (94%) indicated they were familiar with CBCT, and this was especially true for senior students (97%). Notably, 66% of respondents recognized dental and maxillofacial imaging as the primary reason for obtaining a CBCT scan. More than half of the students (53%) correctly recognized higher radiation dose as advantages of CBCT, and almost all the participants (93%) agreed that CBCT is a valuable addition to modern dental care. However, there were gaps regarding safety; only about 69% were aware of radiation safety practices. There were statistically significant differences for several questions across years of study related to having knowledge of CBCT advantages, knowledge of safety practices, and having exposure to training. Only 43% reported having attended a presentation or formal training on CBCT.  Conclusion: The study revealed that knowledge and attitude toward CBCT improve with increasing academic level among dental students. Despite overall awareness, deficiencies remain in areas such as radiation safety and appropriate clinical indications. Incorporating focused training programs and practical learning in the undergraduate curriculum may improve students understanding and promote the judicious use of CBCT in clinical practice.
