摘要

目的:研究基于交流阻抗谱技术(ACIST)的CarieScan Pro (CS)设备在咬合表面的体内性能。受试者和方法:伦理委员会批准了这项研究,参与者给予知情同意。该研究包括来自24名患者的144颗未修复的恒磨牙。采用ICDAS标准目测牙合面。然后进行CarieScan测量。病变的实际深度通过x线片和/或临床在适当的时候打开病变来评估。采用Spearman等级相关系数(rs)评价各方法之间的相关性。计算D3-(牙本质龋)诊断阈值的敏感性(SE)和特异性(SP),并评估ROC曲线下面积(AUC)。结果:ICDAS、CS测量值与参比标准呈正相关(rs 0.37 ~ 0.72, P<0.0001)。ICDAS和CS的AUC分别为0.93和0.84。ICDAS和CS的敏感性/特异性分别为72.0%/96.6%和68.0%/90.8%。ROC曲线比较显示ICDAS与CarieScan Pro的性能差异无统计学意义(P = 0.129)。结论:两种方法对牙合面牙本质龋均有较好的诊断效果。

In-Vivo Performance of the CarieScan Pro Device for Detection of Occlusal Dentine Lesions
Objective: The aim of this study was to evaluate the in-vivo performance of the CarieScan Pro (CS) device based on AC Impedance Spectroscopy technology (ACIST) on occlusal surfaces. Subjects and Methods: The ethics committee approved the study and the participants gave informed consent. The study included 144 unrestored permanent molars from 24 patients. The occlusal surfaces of the teeth were examined visually using ICDAS criteria. Then CarieScan measurements were performed. The actual depth of the lesions was assessed using radiographs and/or clinically by opening the lesion when appropriate. Correlation between all methods was assessed using Spearman's rank correlation coefficient (rs). Sensitivity (SE) and specificity (SP) were calculated at the D3- (dentine caries) diagnostic threshold and the area under the ROC curve (AUC) was assessed. Results: Significant positive correlation was found between ICDAS, CS measurements and the reference standard (rs 0.37–0.72, P<0.0001). The AUC for ICDAS and CS were 0.93 and 0.84, respectively. Sensitivity/specificity for ICDAS and CS were 72.0%/96.6% and 68.0%/90.8%, respectively. Comparison of the ROC curves showed no significant difference between the ICDAS and CarieScan Pro performance (P = 0.129). Conclusion: Both methods showed good diagnostic performance in detection of dentine caries on occlusal surfaces.
