Abstract
Purpose: The aim of this study is to study the impact of change in kilovoltage (KV) or voxel size on extracted 3D radiographic volume measurement of different sizes of endodontic files and to determine the optimal exposure parameters for volume measurement in CBCT.
Methods: Eight different endodontic k files were radiographically exposed at three different kilovoltages using CBCT and divided into three groups, group 1 (80 KV ), group 2 (60 KV ), and group 3 (50 KV ), then exposed to two different voxel sizes, and divided into two groups, group a (300 μm) and group b (180 μm). The 3D radiographic volume and the actual files volumes were measured using ITK-SNAP software and water displacement method respectively.
Finding: Regarding changes in the kilovoltages, no significant difference ( p ˃0.05 ) was reported between the mean of the 3D radiographic volume of groups 3 and 2 with the mean of actual volume with a mean difference of 1.1 ±7.7 mm3 and 2.6 ±9.6 mm3 respectively. The results for voxel size change, showed no significant difference between the mean of the 3D radiographic volume of group (b) and actual volume group with a mean difference of 1.9 ±7.8 mm3. In the other hand, the difference between the mean of volume measurement at group (a) and actual group became significant with a mean difference of 10.5 ±5.7 mm3 was found.
Conclusion: it concluded that both changes in kilovoltage and voxel size parameters affect significantly the 3D volume measurement and reconstruction.
