CBCT Visualization of Furcation Perforation Repair Materials Using Different Voxel Sizes

Background: Three-dimensional cone-beam computed tomography is gaining popularity as an imaging modality aiding the performance of difficult endodontic treatment procedures. For this reason, we assessed visualization bioactive furcal perforation repair materials in ex vivo study using CBCT with different voxel sizes and determined which size yielding best images least artefacts. Visualization restorative material affected by appearance various artifacts. This was conducted to evaluate three five sizes.
 Methods: performed 84 mandibular molars that had been extracted for reasons. All samples were measured a digital caliper (Digimess, São Paulo, Brazil), marked at 3 mm above cementoenamel junction, decoronized line. The root segments amputated below furcation site diamond discs under water cooling. Endodontic access cavities then created, perforations formed. Biodentine, MTA, EndoSequence mixed following manufacturers’ instructions applied sites. Five image sets obtained: 0.075 mm3; 0.1 0.15 0.2 0.4 mm3. Each scan evaluated 2 observers 8 12 years experience imaging.
 Results: quality all achieved Image clarity no statistically difference between mm3 significantly reduced mm3, worst voxels groups.
 Conclusions: can be used examine adjustment effective radiation dose rate selection appropriate size.
