Evaluation of Diagnostic Visibility in CBCT Images with Prosthodontic Crown-Induced Artifacts: Retrospective CBCT Analysis
Year: 2025
Type: article
Study design: Observational Study
Abstract: Background: CBCT is widely used in dental diagnostics, but image artifacts from prosthodontic crowns can reduce diagnostic clarity. This study evaluated the effect of crown materials-metal, PFM, and zirconia-on CBCT visibility. Materials and Methods: CBCT scans of patients with different crowns were retrospectively analyzed. Key landmarks such as the periapical area, lamina dura, and bone were assessed using the diagnostic visibility score (DVS, 0-4). Two observers independently evaluated the scans. Results: Metal crowns produced the most artifacts, followed by PFM crowns. Zirconia crowns caused minimal distortion, preserving visibility. Differences among groups were statistically significant with high interobserver agreement. Conclusion: Zirconia crowns provide better diagnostic visibility in CBCT scans. Crown material selection plays a vital role in image interpretation accuracy.
