| Abstract | ||||
| The purpose of this research was to determine how various voxel sizes affected volume segmentation of the upper canine's pulp area utilizing the following materials and techniques: Following endodontic preparation, images were taken of 20 maxillary canines. The gold standard was the actual physical volume of pulp spaces that had been produced. Three different voxel sizes of the CBCT were used to scan the teeth: (1) Endodontic mode (75 μm) (2) High- dose mode (150 μm), (3) Low- dose mode (400 μm), and. The prepared pulp area was evaluated using a semi-automated segmentation technique by the Materialise Mimics program. Results: For evaluating the physical volume "gold standard," the endodontic mode (75 μm) has excellent agreement (95%), high dose mode (150 m) have admissible agreement (74%) whereas the mode of low dose (400 m) has unsatisfactory agreement (33%). These discrepancies are statistically significant. Conclusions: The accuracy of the segmented volume decreased when the voxel size was increased during scanning. | ||||
