Assessing oral surgery residents' competencies and training needs in tomography interfaces through a usability framework.
Article in BMC medical education, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCone Beam Computed Tomography (CBCT) plays a critical role in oral and maxillofacial surgery (OMFS), yet the training needs of residents regarding CBCT viewer interfaces remain underexplored. Effective utilization of these interfaces is essential for accurate diagnosis and treatment planning. This study aims to assess OMFS residents' competencies in CBCT viewer interfaces and identify training gaps through a usability framework.
methodsOMFS residents participated in a usability evaluation of five CBCT viewer interfaces (VIS: Icad Vision, NNT: Newtom, ODM: OnDemand, OVV: OneVolume Viewer, ROM: Planmeca Romexis). Effectiveness was measured through task completion rates, efficiency through task duration, mouse clicks, and cursor distance, and satisfaction using the System Usability Scale (SUS) and the Computer System Usability Questionnaire (CSUQ). Statistical analysis included Friedman and Dunn's tests with Benjamini-Hochberg correction.
resultsResidents reported receiving no hands-on CBCT training and relied only on verbal instruction during dental school, suggesting a lack of structured training. All of them successfully completed tasks on all interfaces, indicating 100% effectiveness. However, significant differences in efficiency and satisfaction were observed, reflecting varying levels of proficiency and highlighting areas where further training could be beneficial. VIS interface required significantly more time (198.4 ± 70.44 s) and mouse clicks (69.82 ± 33.17, p < 0.05) compared to other interfaces, suggesting a need for additional practice with this interface. The ODM interface achieved the highest SUS score (69.89 ± 22.79), while the VIS interface had the lowest (41.82 ± 22.90) (p < 0.05). Only ODM approached the industry-standard threshold for user satisfaction, while the remaining systems failed to meet this criterion.
conclusionsThis study highlights the need for structured training in CBCT viewer interfaces for OMFS residents. Findings suggest that a standardized, hands-on multi-software program should be integrated into residency curricula to improve efficiency, reduce cognitive load, and enhance clinical decision-making. Future research should focus on the long-term impact of usability-driven training on clinical performance and patient outcomes.
