Abstract

Objectives

To present the methods used to study the reliability and validity of twodimensional cephalometry, the programs and systems tested, and the most troublesome cephalometric measurements and points.

Methods

We performed a literature review of published studies on digital cephalometric Software. A total of 28 articles, published from 1981 to 2011, met the study requirements. The elements studied in the articles were in various two-dimensional formats (X-ray film, digital copy printing, scanner, software).

Results

X-ray film showed the best cephalometric tracing. Digital radiography obtained directly or scanned in high resolution radiographic film showed values closest to manual tracing, but digital photography of the film showed significant differences.

Conclusions

The latest software is reliable for clinical cephalometric study. As advances in the software were made, differences with older programs became fewer.

更新二维数字头影测绘方法的有效性

目的介绍研究二维头颅测量的信度和效度的方法、测试的程序和系统，以及最麻烦的测量点和难点。方法对已发表的有关数字头颅测量软件的研究进行文献回顾。在1981 - 2011年共发表了28篇符合研究要求的文章。文章中研究的元素是各种二维格式的(x射线胶片、数字复印、扫描仪、软件)。结果x线片表现出良好的头颅示踪。直接获得的数字射线摄影或高分辨率射线摄影胶片扫描显示的数值最接近人工追踪，但胶片的数字摄影显示出显着差异。结论最新软件可用于临床头颅测量研究。随着软件的进步，与旧程序的差异越来越小。
