| Abstract | ||||
| purpose: Assessment of the accuracy of different voxel sizes of CBCT in evaluation of various infrabony defects (both linear and volumetric). Accuracy of 2 different software systems in volumetric measurements of alveolar bone defects. Methods: This study included 2 parts. An in vitro study included 10 dry mandibles, 60 classified artificial defects were created on the mandibles. Linear and volumetric measurements were done on mandibles and CBCT. The data then compared with CBCT data with different voxel sizes on 2 different software programs. An in vivo study on 5 patients with periodontal bone defects and scheduled for flap surgery. Linear and volumetric measurements were done both intra-surgical and on CBCT. Data analyzed and compared on 2 different software programs. Results: no significant difference in both linear and volumetric measurements of all alveolar bone defects when comparing CBCT with actual measurements. No significant difference between the 2 software packages used for volume evaluation. No difference between 0.1 and 0.2 mm voxels. Conclusions: This study shows that CBCT is very accurate in identifying and quantifying alveolar bone loss and thus can be used in diagnosis of periodontal diseases. Both software used can give accurate results. Smaller voxels give more accurate results. | ||||
