Summary
This study found no significant difference in detecting root fractures using different cone-beam computed tomography settings. The 100 µm high-resolution mode without an optimization filter is recommended for endodontically treated teeth.
Area of Science:
- Dental imaging
- Endodontics
- Radiology
Background:
- Accurate detection of root fractures is crucial in endodontic treatment.
- Cone-beam computed tomography (CBCT) is a common imaging modality for evaluating endodontic complications.
Purpose of the Study:
- To assess the impact of optimization filter (OF) and voxel size on the accuracy of root fracture detection using CBCT.
- To determine the optimal CBCT imaging parameters for identifying root fractures in endodontically treated teeth.
Main Methods:
- Forty endodontically treated roots, half fractured, were scanned using Planmeca ProMax 3-D with 75 µm and 100 µm voxel sizes, with and without an OF.
- Five reviewers assessed fracture presence on a 5-point scale.
- Data analyzed for intra-/interobserver agreement, accuracy, sensitivity, and false-positive rates.
Main Results:
- Strong intra- and interobserver agreement was observed (high κ-values).
- No statistically significant differences in fracture detection accuracy were found among the tested CBCT settings.
- All evaluated techniques demonstrated comparable performance in identifying root fractures.
Conclusions:
- The 100 µm high-resolution mode without an OF is recommended for root fracture detection.
- This setting offers advantages in reduced cost, radiation dose (dose area product), and scanning time compared to other modalities.
- This approach provides a cost-effective and efficient method for evaluating root fractures in endodontically treated teeth.
