Although smooth-surface caries can be subjectively assessed by visual inspection, quantitative methods would improve the monitoring of these lesions.
To evaluate the in vitro performance of laser fluorescence devices, namely DIAGNOdent (LF) and DIAGNOdent pen (LFpen), and a fluorescence camera (VistaProof; FC) in the detection and quantification of smooth-surface caries in primary teeth.
Two examiners evaluated 99 smooth surfaces of 65 extracted primary molars using FC, LF, and LFpen. As a reference standard, the actual and relative lesion depths were determined using stereomicroscopy and polarized light microscopy. Reproducibilities were assessed, and correlation analyses were performed. The sensitivities, specificities, and accuracies of the methods were calculated and compared.
There was a significant correlation between the values obtained using the fluorescence-based devices and the actual and relative lesion depths, although the correlation coefficient values were not higher than 0.7 (LF, 0.673; LFpen, 0.646; FC, 0.663). The sensitivities of the devices were similar for the detection of enamel caries, although LFpen was superior in detecting dentin lesions. The reliabilities of all methods were moderate to low, with similar accuracies at all depths.
Although the fluorescence-based devices showed similar performance in the detection of enamel and dentin lesions, the reliability of these devices and the correlation of their findings with the actual and relative lesion depths were moderate with regard to smooth-surface caries in primary molars.
尽管平滑面龋可通过视觉检查进行主观评估，但定量方法将改善对这些病变的监测。
评估激光荧光设备，即DIAGNOdent（LF）和DIAGNOdent笔（LFpen）以及荧光相机（VistaProof；FC）在乳牙平滑面龋检测和定量中的体外性能。
两名检查者使用FC、LF和LFpen对65颗拔除的乳牙磨牙的99个平滑面进行评估。作为参考标准，使用立体显微镜和偏振光显微镜确定实际和相对病变深度。评估再现性，并进行相关性分析。计算并比较这些方法的敏感性、特异性和准确性。
尽管相关系数值不高于0.7（LF为0.673；LFpen为0.646；FC为0.663），但使用基于荧光的设备获得的值与实际和相对病变深度之间存在显著相关性。这些设备在检测釉质龋方面的敏感性相似，尽管LFpen在检测牙本质病变方面更具优势。所有方法的可靠性为中度至低度，在所有深度的准确性相似。
尽管基于荧光的设备在检测釉质和牙本质病变方面表现相似，但就乳牙磨牙的平滑面龋而言，这些设备的可靠性及其结果与实际和相对病变深度的相关性为中度。
