The aim of the present study was to compare the effect of application of an image processing mode of a colorizer on the efficacy of the detection of interproximal carious lesions viewed in direct digital radiography.
A total of 102 proximal surfaces of extracted human premolars on direct digital images were evaluated by three observers with and without the application of pseudocolor filter. The teeth were sectioned and viewed microscopically to determine the gold standard. The kappa value agreement ratios were calculated.
Sensitivity and specificity values for normal digital and colorized images were 66.7%, 60%, 80.5%, and 50%, respectively. However, there were no statistically significant differences between the two types of images (P = 0.12).
In this study application of pseudocolor filter on digital radiographic images failed to result in significantly improved caries detection.
本研究的目的是比较在直接数字放射成像中应用一种彩色化图像处理模式对邻面龋损检测效果的影响。
三名观察者对102个直接数字图像上的拔除人类前磨牙邻面进行评估，分别在应用和未应用伪彩色滤镜的情况下。将牙齿切片并进行显微镜观察以确定金标准。计算kappa值一致性比率。
正常数字图像和彩色化图像的敏感度和特异度值分别为66.7%、60%、80.5%和50%。然而，两种类型图像之间无统计学显著差异（P = 0.12）。
在本研究中，在数字放射图像上应用伪彩色滤镜未能显著提高龋损检测效果。
