This article is devoted to the comparison of optical density indicators, topographic-anatomical location of odontogenic cysts, tumors and tumor-like neoplasms of the jaws. The purpose of the study was to compare the data of 3D visualization of radiological sections of images of cysts, tumors and tumor-like lesions of mandible when using CT and CBCT. 3D imaging provides a detailed view of neoplasms in the bone tissue of jaws and the structure of surrounding organs, such as the tooth, its roots, and the state of the pulp. Analyzing CT and CBCT data, surgical treatment can be accurately planned at the planning stage. So far, quite a few data have been found on the comparative characteristics of CT and CBCT data, some of them are of a contradictory nature, which formed the basis of this direction of research. 85 patients participated in the study. Of them, 21 people visualized two neoplasms each. All imaging objects were measured by CT and CBCT. At the first stage, the new growth was measured three times in the axial direction of the plane using the computer interpolarization algorithm, and at the second stage, the new growth was outlined in all three planes. According to the conducted research, the difference in the estimation of both methods was 0.01268 and the limits of the amplitudes were 0.28367 and 0.29836, respectively. The variance of the first method was equal to 0.009891, and the variability indicator of the second method was 0.02164. The difference in optical density between the two methods was 0.00245, and the total variance of the difference was 0.1229. A least squares mean of 0.01627 associated with a confidence interval is evidence that the two methods give nearly the same results, a value of 0.1627 suggests that the null hypothesis is that the two methods give the same results. Determining the non-invasive volume of neoplasms of the jaws is useful in preoperative diagnosis, and the availability of 3D-MAX software and high-quality CT / CBCT scans is a necessary condition for creating the correct surgical intervention algorithm and detecting the presence of potential intra- and postoperative complications.
