Background/Objectives: Evaluation of artifact expression in CBCT images caused by different intracanal medications (IMs) considering variations scanning and reconstruction protocols. Reconstruction protocols refer to the specific parameters image processing techniques applied during acquisition, including voxel size, slice thickness, reduction settings. MicroCT was used as reference standard. Methods: Root canal preparation (45./05) upper canines performed, teeth were divided into four groups (n = 10) according IM used: G1: Ultracal XS (UC); G2: Bio-C Temp (BCT); G3: Metapex (MT); G4: Metapaste (MP). The specimens sealed with temporary provisional material stored at 37 °C 100% humidity for 7 days. Then, they scanned using microCT (SkyScan 1174) two CBCTs high low resolutions: EagleX3D OP300. Image registration performed FIJI ImageJ software (v. 1.54k). Axial, sagittal, coronal reconstructions quali-quantitatively evaluated calibrated examiners following scores artifacts (dark streaks, hypodense areas, distortion): definitely absent; probably not sure; present present; possibility endodontic diagnosis: No/Yes. Statistical analysis Fleiss' kappa test two-way ANOVA (α 95%). Results: showed greater volume distortion medication (p < 0.05) compared images. X3D highest values distortion, regardless resolution, OP300 0.05). lowest observed UC BCT groups, respectively Conclusions: Intracanal generates metallic images, hampering diagnosis.
