The purpose of the study was to assess the diagnostic possibilities and interobserver agreement between the radiologist the CBCT and panoramic tomography in diagnostics of radiopack lesions in the maxillo-facial region. The study design: the results of morphological and radial examination of 272 patients with radiopack lesions in the maxillo-facial region were assessed. Consistency among the radiologists was evaluated by means of Cohen»s kappa. The diagnostic signi cance of the results was assessed using Student»s t-test. Results: CBCT sensitivity was 98%, speci city – 89%, diagnostic accuracy – 97%. Sensitivity of the panoramic tomography of the dental alignments was 69%, speci city – 44%, diagnostic accuracy – 64%. The area under the ROC-curve for the panoramic tomography – 0,612 (p˂0,05), for the CBCT – 0,937 (p˂0,05). Interobserver agreement in estimating the panoramic tomography was satisfactory (k=0,24, p˂0,001), it was high for the CBCT (k=0,83, p˂0,0001).
