Abstract
The purpose of this study was to assess the accuracy of images captured from i-CAT® cone beam computed tomography compared to conventional digital cephalograms. The magnitude of and difference compared to dry skull measurements of six cephalometric linear measures were made on 33 human dry skulls. Also, several cephalometric angles were compared. The data was analyzed using one-way analysis of variance and by t-tests to determine statistical significance. Minor differences were found for the angular measurements between the two imaging techniques. Five of the six linear measurements were found to be longer, but clinically accurate, using both imaging techniques. The measurement Co- Gn, however, was shorter and clinically inaccurate using both imaging techniques. This inaccuracy was greater for the conventional digital cephalograms compared to i-CAT. There was a statistically significant difference between the two imaging techniques and between both imaging techniques and the dry skull measurements for Co- Gn.
