目标
测试改变图像尺寸对诊断质量的影响。
方法
在上下磨牙和前磨牙中准备尺寸为10和15的根管锉，使其达到完整的根长和1.5 mm短。将Sidexis（S）和Visualix/Vixa（V）系统的数字图像缩小至迪戈拉（D）比例，并将D图像放大至S比例。进行ROC分析，并采用MANOVA统计分析数据。
结果
用10号锉测量根管长度的准确性在缩小后的S型图像上低于原始S型图像（P < 0.011）。其他各项差异均无显著性（P > 0.081）。
结论
当图像尺寸减小时，相关诊断信息可能会丢失。因此，为了获得最佳呈现效果，应放大较小的图像，而不是缩小较大的图像。
OBJECTIVES
To test the effect of altering image size on diagnostic quality.
METHODS
Endodontic files, size 10 and 15 were prepared to full root length and 1.5 mm short, in upper and lower molars and premolars. Digital images of the Sidexis (S) and Visualix/Vixa (V) system were reduced in size to Digora (D) scale, and the D images were enlarged to S scale. ROC analysis was performed and data analysed with MANOVA statistics.
RESULTS
Assessment of root canal length with file size 10 was less accurate for the S images reduced in size, compared with the original S images (P < 0.011). All other differences were not significant (P > 0.081).
CONCLUSIONS
Relevant diagnostic information may be lost when images are reduced in size. Therefore, for optimal presentation, the smaller images should be enlarged rather than the larger ones reduced.
