Summary
A new artifact reduction tool in cone beam computed tomography (CBCT) software accurately measures root canal filling materials. This imaging technology enhances endodontic treatment evaluation by reducing artifacts from obturation materials.
Area of Science:
- Dentistry
- Radiology
- Endodontics
Background:
- Cone beam computed tomography (CBCT) is increasingly utilized in dentistry.
- Endodontists are gaining access to CBCT technology for various applications.
- Artifacts from root canal filling materials can affect CBCT image quality.
Purpose of the Study:
- To evaluate an artifact suppression algorithm in CBCT software.
- To assess the algorithm's effectiveness in reducing artifacts from root canal filling materials.
- To compare measurements of root canal fillings with and without artifact reduction.
Main Methods:
- Eighty-four mandibular molars with endodontically treated mesial root canals were used.
- Four different root canal sealers were applied.
- CBCT scans were acquired, and root canal filling diameters were measured using a digital micrometer and CBCT software with an artifact reduction tool.
Main Results:
- No statistically significant differences were found between micrometer and CBCT software measurements.
- The blooming artifact reduction (BAR) tool in e-Vol DX software was evaluated.
- Measurements were taken in mesiodistal and buccolingual directions.
Conclusions:
- The tested CBCT software algorithm effectively suppressed artifacts caused by obturation materials.
- The artifact reduction tool did not compromise the accuracy of root canal filling measurements.
- This technology can improve the diagnostic quality of CBCT in endodontics.
