Comparative Evaluation of Artifacts Originated by Four Different Post Materials Using Different CBCT Settings.

Unlabelled: The aim of this study was to evaluate whether cone beam computed tomography (CBCT) images in the presence of four different post materials, obtained from different kVps with varying resolutions and varying metal artifact reduction (MAR) algorithms, differed in artifact estimation, and to compare tooth regions in terms of artifact value.

Materials And Methods: Forty premolar teeth were used in this study. Root canals were treated, and teeth were randomly distributed into four subgroups ( = 10) for the preparation of post materials: titanium, gold (Nordin), quartz fiber (Bisco DT Light), and glass fiber (Rely X).
