| Popis: | To assess linear and volumetric measurement accuracy of periodontal defects (class 2 furcation, fenestration, dehiscence, and three-wall intrabony defect) by using CBCT and micro-CT images obtained at different voxel sizes. We created 66 periodontal defects in human dry mandibles. Images of teeth with defects were taken by Planmeca Promox 3D Max (CBCT) at voxel sizes of 0.2 and 0.075 mm and super-argus PET/CT (micro-CT) at voxel sizes of 0.12 and 0.06 mm. All defects were then linearly (depth, width, and height) and volumetrically measured by 3D-DOCTOR software. Differences between voxels were assessed by Wilcoxon signed rank test. Bland-Altman limits of agreement and ICCs were calculated to assess agreement between the methods. Significance was set at p |
