Abstract

Objective To assess the accuracy of linear measurements from stitched and non-stitched cone beam computed tomography (CBCT) images in comparison to direct measurements. Materials and methods Ten dry human mandibles were marked with gutta-percha at reference points to obtain five vertical and five horizontal distances. CBCT using stitching and non-stitching programs were performed. All distances on CBCT images obtained using stitching and non-stitching programs were measured and compared with direct measurements. The intraclass correlation coefficients (ICCs) were calculated. Results The intraobserver ICCs of direct measurements were 0.998 to 1.000, and those of measurements on both non-stitched and stitched CBCT images were 1.000. The intermethod ICCs between direct measurements versus non-stitched CBCT images and direct measurements versus stitched CBCT images ranged from 0.972 to 1.000 and 0.967 to 0.998, respectively. No significant differences were found between direct measurements and stitched or non-stitched CBCT images (p > 0.05). Conclusion Linear measurements from stitched and non-stitched CBCT images were accurate compared with direct measurements.
