CBCT Performance and Endodontic Sealer Influence in the Diagnosis of Vertical Root Fractures.

Aim: To evaluate the performance of three cone beam computed tomography (CBCT) machines in detecting vertical root fractures (VRFs) in teeth filled with different sealers.

Materials And Methods: A total of 80 single-rooted premolars were subjected to instrumentation and restoration with gutta-percha + AH Plus sealer, gutta-percha + sealer 26, gutta-percha + fill canal, and gutta-percha without sealer as the control. Half of the samples were randomly subjected to root fracture and all the teeth were scanned by i-CAT (Imaging Sciences International, Hatfield, USA), PreXion (PreXion Inc.
