Abstract:
PURPOSE: To compare alveolar bony height of pantomograph with bony height of thin slice, multiplanar reformatted (MPR) Computed Tomograph. MATERIALS AND METHODS: Panoramic radiograms of 12 young adult patients had been taken by one radologic technitian and the measurements were corrected by magnification ratio (1.20). The slice thickness of Multi-detector Computed Tomography (CT) was at least 1mm for the accuracy. The raw CT datas were imported into the V-works 4.0 (CyberMed Corp., Seoul, Korea) and transformed to MPR images. Pantomographic measurements of alveolar bone were compared to CT values by average mean bony height measurements for the accuracy. Inter-, and Intraobserver variability was evaluated. RESULTS: There was no significant differences between height measurement of pantomography and that of CT (P> 0.05). There were no significant differences in either inter- or intra-observer measurements (P> 0.05). CONCLUSION: Pantomography showed relatively high accuracy and precision in measuring alveolar bony height.
