An index and a score system for radiographical longitudinal studies of caries progression on proximal tooth surfaces are presented and compared with the DF-surface system. Generally, a good correlation between DF-surface differences and scores was found in a three-year study on teenagers. However, the score system seems to forward better means for a detailed study of the individual.
本文提出了一种用于近端牙面龋进展的影像学纵向研究的指数和评分系统,并将其与DF-面系统进行了比较。总体而言,在一项针对青少年的三年研究中,发现DF-面差异与评分之间具有良好的相关性。然而,评分系统似乎为个体的详细研究提供了更好的方法。
