Landmark identification accuracy in xeroradiographic cephalometry

Identification accuracy of fourteen cephalometric landmarks was compared between xeroradiographic cephalograms and conventional cephalograms. Four landmarks—point A, upper incisor tip, infradentale, and menton—were more accurately determined on the xeroradiograph, while two landmarks—point B and condylion—were more accurately determined on the conventional cephalogram. Although not conclusively demonstrated in this study, the xeroradiograph does appear to offer more clarity and detail than the conventional cephalogram. Further investigation of this new diagnostic medium will be necessary before its true significance to dentistry can be evaluated.
