Panorex Interpretation of the Mesio-Distal Axial Inclinations and Mesio-Distal Diameters of the Posterior Teeth

Abstract

Sixteen adult human skulls with "normal occlusion" were examined with the Panorex to determine its ability to record the mesio-distal axial inclinations and the mesio-distal diameters of the posterior teeth. This study indicates that the Panorex can be used as a qualitative and quantitative instrument in the study of the mesio-distal axial inclinations of the posterior teeth. A series of means and standard deviations for each posterior tooth as interpreted by the Panorex was developed. Individual measurements of posterior teeth as seen on the Panorex can now be related and compared to these standards so that they are valuable in the diagnosis, treatment, and evaluation of orthodontic cases. Further research is necessary, however, to accurately interpret the mesio-distal diameters of the posterior teeth as seen on the Panorex if these measurements are to be used for arch length analysis.
