Aim: The aim of the present study is to test the accuracy of cone-beam computed tomography (CBCT) in detecting simulated root fractures (RFs) in endodontically treated teeth with different post and cores. Materials and Methods: Forty maxillary central incisors without any defects were randomly divided into four groups (n = 10) according to type of posts; Group A (Cast), B (fiber-reinforced composite post [FRC]), C (hybrid composite), and D (control, without any post). Except teeth in Group D, all of the samples were endodontically treated and prepared for post restoration. Using a reference, FRC post and core, cast post and core, and core build-up in Group C were completed. In Group C, hybrid composite was placed directly into post space. All of the samples were prepared for standard metal crowns considering 2 mm of the ferrule in their preparation. To simulate clinical situation, teeth were mounted in 135° angulation. A universal testing machine was used to fracture the teeth. Then, the CBCT scans were obtained, and three oral and maxillofacial radiologists assessed the images for the presence of RFs. The data were analyzed using IBM SPSS version 20.0 (IBM Corp., Armonk, NY, USA). Results: There was no significant difference among four groups. The lowest sensitivity was for Group A and B. Kappa coefficient for first and second observer was 0.972 ± 0.0391 and for third observer 0.876 ± 0.0391 (P > 0.05). Conclusion: Within limitations of this in vitro study, different postmaterials had no significant effect on diagnostic abilities of CBCT in detecting RFs.
