Impact of Examiner Training and 3D Reconstruction on CBCT Detection of Anatomical Microstructure.

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
Cone-beam computed tomography (CBCT) has become a reference imaging method in dentistry, providing higher diagnostic accuracy and detailed visualization of complex internal anatomy. This study evaluated the impact of examiner training and three-dimensional (3D) reconstruction on CBCT detection of anatomical microstructures. CBCT scans obtained from 30 teeth with anatomical variations were evaluated by examiners across five skill levels. The same anatomical structures (root canals, isthmuses, and foramina) were assessed using dynamic navigation with multiplanar reconstruction (MPR) and a 3D reconstruction tool available in the e-Vol DX software. The experimental groups included the examiners: undergraduate student, undergraduate student with specific CBCT training, general practitioner, endodontist, and radiologist (control). Each examiner analyzed axial slices with and without 3D reconstruction, recording the number of structures identified and the influence of 3D assistance. Data were analyzed using Kolmogorov-Smirnov, Mann-Whitney, and Kruskal-Wallis tests (p < 0.05). For the general practitioner, 3D reconstruction significantly increased identification of root canals and foramina (p < 0.05), while other groups showed no significant differences between analyses. All examiners reported higher diagnostic confidence when using 3D reconstruction, with endodontists, general practitioners, and trained undergraduates indicating benefit in 100% of cases, and untrained undergraduates in 60%. The 3D reconstruction tool positively influenced the general practitioner's ability to detect root canals and foramina in mandibular premolars with complex anatomy. When using 3D reconstruction, examiners at all training levels achieved good diagnostic performance, enhancing both accuracy and confidence in anatomical interpretation.
