The objective of this study was to evaluate the repeatability of 2 nondestructive caries detection methods, ultrasound (ULS) and DIAGNOdent, for the detection of approximal caries lesions, and to evaluate 2 tips provided for the DIAGNOdent.
White/brown-spot lesions (n = 42) were captured by a digital camera, and measured by test methods and confocal laser scanning microscope (CLSM). Intra- and inter-observer reliability, accuracy, and Cohen's kappa and Spearman's rho statistics were used.
At DIAGNOdent, intra-observer agreements were 78.5%, 66.7% for A tip and 59.5%, 47.6% for B for 2 examiners, respectively. Accuracy of both tips was 50% for the first examiner; 45.3% for A and 47.6% for the B tip for the second examiner. All ULS measurements were accurate, reliable, and positively and significantly correlated between examiners.
The A tip of the DIAGNOdent was found to be better than the B tip for the detection of enamel caries. All DIAGNOdent and ULS measurements were positive and significantly correlated for both examiners. Both methods demonstrated high repeatability and accuracy.
本研究的目的是评估两种非破坏性龋齿检测方法，即超声（ULS）和DIAGNOdent，用于检测邻面龋损的重复性，并评估为DIAGNOdent提供的两种探头。
用数码相机采集白色/褐色斑点病变（n = 42），并通过测试方法和共聚焦激光扫描显微镜（CLSM）进行测量。使用观察者内和观察者间的可靠性、准确性以及科恩kappa系数和斯皮尔曼等级相关系数统计。
在DIAGNOdent检测中，两位检查者的观察者内一致性分别为：A探头78.5%、66.7%，B探头59.5%、47.6%。第一位检查者两种探头的准确性均为50%；第二位检查者A探头为45.3%，B探头为47.6%。所有超声测量结果准确、可靠，且检查者之间呈正相关且具有显著性。
发现DIAGNOdent的A探头在检测牙釉质龋方面优于B探头。两位检查者的所有DIAGNOdent和超声测量结果均呈正相关且具有显著性。两种方法均显示出高重复性和准确性。
