Abstract

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.

摘要

比较了干板X线头颅侧位片和传统头颅侧位片上14个头颅测量标志点的识别准确性。四个标志点——A点、上切牙切端、下齿槽座点和颏下点——在干板X线片上的测定更准确，而两个标志点——B点和髁突点——在传统头颅侧位片上的测定更准确。尽管本研究未得出确凿结论，但干板X线片似乎确实比传统头颅侧位片提供了更清晰的图像和更多细节。在评估这种新的诊断介质对牙科的真正意义之前，有必要对其进行进一步研究。
