The purpose of this study was to evaluate the accuracy of volumetric analysis software packages in assessment of tooth volume using cone beam computed tomography and compare them to the volume obtained using an optical digital scanner. Twenty-four single rooted teeth indicated for extraction were collected. Cone beam computed tomography scans of these teeth resting in a custom scan jig were taken. Three dimensional digital models were obtained from the DICOM image cone beam computed tomography files using segmentation software packages (Anatomage, Mimics, and Amira) and volumes were calculated for each of the segmented teeth. The teeth were then scanned using a 3-shape digital scanner. The stereolithographic files were used to calculate the volume. Volumetric analysis comparisons were made between the stereo-lithographic scanner measurements and the individual cone beam computed tomography software measurements of the segmented data. The intraclass correlation coefficient was used for the reliability tests. Friedman’s two-way analysis of variance was used to com-pare the volume obtained from the software programs.
