RESUMO
This study aimed to analyze and compare volumetric tomography Cone- Beam and periapical examination, by technique of Clark, identifying accidents and endodontic complications, which were simulated, for endodontic interest. Sixteen human teeth from three human jaws were submitted to preparation of 20 changes/injuries in order to simulate situations that can lead to complications for diagnosis and endodontic treatment. The simulations were divided into four groups: G1) fragment of fractured file in radicular duct; G2) holes/slots in radicular duct; G3) metal cores with deviation from the path of root canal and, G4) external resorption. Each tooth was submitted to examination of periapical radiography, by technique of Clark and each jaw, by the examination of Cone-Beam Computed Tomography. The analysis of the tests was performed by a single observer, a specialist in dental radiology. The overall results using McNemar statistical test showed a difference statistically significant (p <0.05) for Cone-Beam Computed Tomography if compared to periapical radiographs. Statistical analysis of individual results for alteration/defect, using Wilcoxon statistical test showed superiority of Cone-Beam Computed Tomography to identify resorptions, with statistically significant value (p <0.05). According to the results it can be concluded that, generally, the Cone-Beam Computed Tomography showed superiority in relation to conventional periapical radiographs, identifying simulated changes/injuries
