OBJECTIVES: Cone Beam Computed Tomography (CBCT) is a widely used imaging technology in dentistry, requiring specialized training and a specific license in Germany. This study aimed to evaluate the effectiveness of an e-learning platform for acquiring CBCT knowledge and to examine participant satisfaction and experiences.
METHODS: The study included German dentists, half with CBCT license and half without. The participants completed an online pre-test with 15 image-based questions to assess basic knowledge and then were given access to the e-platform containing 104 annotated CBCT cases (e.g. implant planning, cysts, or impacted teeth). After 8-10 weeks, a post-test similar to the pre-test was conducted. An 11-item questionnaire recorded participant experience. Data were analysed using independent and paired t-tests, and Fisher's exact test; p < 0.05 was considered statistically significant.
RESULTS: Between May and October 2025, 32 dentists participated in the study (16 with and 16 without CBCT license). Learning with the e-learning platform led to a significant increase in knowledge (p < 0.001). Participants with CBCT license had higher baseline scores than those without (75.8% vs. 69.3%; p < 0.05); after the learning phase, the difference was no longer significant (p = 0.37), with final scores of 83.1% and 80.6%, respectively. Regardless of CBCT license status, dentists found the platform to be a valuable tool for enhancing diagnostic skills, offering a user-friendly, case-based structure.
CONCLUSIONS: The digital learning platform significantly improved CBCT-related diagnostic skills and dentists, both with and without a CBCT license, found the platform practical and easy to use.
