Abstract

Aim The aim of this study was to assess the accuracy of linear measurements on cone beam computed tomography (CBCT) images of human cadaveric mandibles and to establish its use in various diagnostics and dental treatment modalities. Materials and methods A prospective cohort study was carried out using four dried human mandibles that were obtained from the Department of Anatomy Topiwala National Medical College (TNMC) on which 10 different linear distances between defined anatomical points were identified and instrumented with K files (number 08) and then imaged using Kodak 9000 3DVT X-ray machine-CBCT mode. Electronic linear measurements of bone height were measured using Kodak viewing software. Physical measurements were done with digital calibrated calipers at the same location. The measurements were performed three times by three experienced observers and the mean of the measurements was taken as dimensional truth. Results Intraclass correlation obtained with respect to each mandible and for each method of evaluation (Vernier caliper and CBCT) by the three observers was found to be highly significant (p < 0.001) and amounted to 0.996 [95% confidence interval (CI)], making all the readings justifiable. On comparing measurements by CBCT with gold standard Vernier calipers, we found the p-value to be greater than that of 0.05, mean difference of Vernier Callipers (VC) and CBCT is −0.0283, indicating that the mean difference is not equal to zero, and thus the CBCT results are almost equal to VC. Conclusion The present study reveals that we are now able not only to provide more accurate diagnosis with this imaging modality, but also to guide and assess various surgical and clinical interventions.
