The authors conducted an in vivo study to compare a laser fluorescence system with a visual system for occlusal caries diagnosis in children's primary and permanent molars.
The authors selected for evaluation 320 untreated, cavity-free primary and permanent molars in healthy children aged 6 through 14 years. Two of the authors conducted the laser fluorescence evaluation. Another of the authors completed the clinical evaluation. The kappa value was 0.68. The authors compared sensitivity, specificity, predictive values, odds ratio and receiver operating characteristic (ROC) curves for the laser fluorescence system.
For the whole sample, the sensitivity and specificity of the laser fluorescence system were 0.79 and 0.87, respectively. The positive and negative odds ratios for the whole sample were 6.33 and 0.23. The positive and negative predictive values for the whole sample were 33.9 percent and 98.1 percent. The value of the area beneath the ROC curve (AUC) was 0.92 for the whole sample.
The laser fluorescence system was more precise than visual evaluation in identifying lesions without cavities and healthy surfaces in primary and permanent molars.
In daily practice, dentists can consider the laser fluorescence system a complementary tool in the visual exploration of occlusal surfaces of primary molars and permanent first molars.
作者进行了一项体内研究，以比较激光荧光系统和视觉系统对儿童乳牙和恒牙咬合面龋齿的诊断效果。
作者选取了320颗6至14岁健康儿童未经治疗、无龋洞的乳牙和恒牙进行评估。两名作者进行激光荧光评估。另一名作者完成临床评估。kappa值为0.68。作者比较了激光荧光系统的敏感性、特异性、预测值、优势比和受试者工作特征（ROC）曲线。
对于整个样本，激光荧光系统的敏感性和特异性分别为0.79和0.87。整个样本的阳性和阴性优势比分别为6.33和0.23。整个样本的阳性和阴性预测值分别为33.9%和98.1%。整个样本的ROC曲线下面积（AUC）值为0.92。
在识别乳牙和恒牙中无龋洞病变和健康表面方面，激光荧光系统比视觉评估更精确。
在日常实践中，牙医可将激光荧光系统视为乳牙和恒牙第一磨牙咬合面视觉检查的辅助工具。
