Özet

Abstract

Background

Cone Beam Computed Tomography (CBCT) is widely used in dentistry; however, many practitioners have limited knowledge regarding its appropriate indications and radiation safety protocols. Optimizing CBCT use is essential for both patient safety and diagnostic efficacy. This study aimes to evaluate Turkish dentists’ and dental specialists’ awareness, attitudes, and practices regarding CBCT usage, radioprotection, and dose-reduction measures.

Methods

A nationwide cross-sectional study was conducted from November 2021 to February 2024, involving 306 volunteer dentists with 1 to 51 years of clinical experience. Participants completed an 18-item questionnaire covering CBCT usage frequency, imaging indications, technical parameter selection, radiation protection and training. Statistical analysis included Chi-square and Kruskal-Wallis tests.

Results

Implant planning, lesion evaluation, and root morphology assessment were the most common reasons for CBCT use. Oral and maxillofacial radiologists used CBCT more frequently than other specialists. A significant relationship was observed between frequency of CBCT use and the selection of technical parameters (voxel size, field of view) (p < 0.001). While lead apron usage was common, thyroid collar usage varied and showed a significant relationship with scan frequency (p = 0.001). Most participants relied on automatic settings and did not consistently consult a radiologist either before or after imaging.

Conclusions

The study reveals knowledge gaps in CBCT usage and radiation protection practices among dental professionals. Ongoing professional education and clearer guidelines are essential to ensure safe and effective use of CBCT technology.
