The aim of this study was to develop a computerized measurement system for analysis of unstandardized serial radiographic images. A new approach for estimating the error associated with the determination of alveolar crest loss is described. The study shows that a difference of 0.87 mm in cemento-enamel junction-crest measurement between unstandardized serial radiographs taken within accepted clinic routine is required for a significant loss in crestal bone height. The ability to detect with significance a difference of less than 1 mm in crestal bone height makes the appropriate use of traditional bite-wing radiographs a useful diagnostic tool for the assessment of periodontal maintenance.
本研究的目的是开发一种用于分析非标准化系列X线影像的计算机测量系统。描述了一种估计与牙槽嵴吸收测定相关误差的新方法。该研究表明，在临床常规接受的范围内拍摄的非标准化系列X线片之间，牙骨质-釉质界至牙槽嵴的测量值相差0.87 mm时，牙槽骨高度才会有显著降低。能够显著检测出牙槽骨高度小于1 mm的差异，使得合理使用传统的咬合翼片成为评估牙周维护情况的有用诊断工具。
