Objectives: This project included the development of an educational module addressing cone beam computed tomography (CBCT) basics, anatomy, and interpretation of CBCT reconstructed multiplanar images containing pathology. The subsequent objective was to test the efficacy of this educational tool. Methods: 32 Navy dental providers completed a brief online demographic survey and multiple-choice pretest evaluating their knowledge of CBCT. The web based educational module was then made available to the cohort. After completing the module, participants were given the link to the posttest and short feedback questionnaire. Results: 24 posttests and feedback questionnaires were completed. The data demonstrated an increase in the number of correct responses between the pre and posttests which was not statistically significant when comparing overall scores. (75.2% (pretest) to 77.5% (posttest) [p=.379]). Interestingly, the results limited to sectional scores provided different outcomes. The basics/anatomy sections combined yielded a statistically significant change from 77.4% to 86.6% (p= .010). The interpretation section, however, saw a decrease in performance. (Pretest=69.7% vs. Posttest=58.6% [p=.400] ) 100% of respondents agreed that the module was helpful and met its objective. Conclusions: The information presented in the CBCT basics and anatomy sections of the module resulted in the participants' increased performance on the posttest. The decrease in performance on the interpretation section could be attributed to the skill set required to interpret CBCT multiplanar images. Image interpretation is a skill set that cannot be developed using a few examples of how disease is manifested radiographically.
