Abstract：
The aim of this study was to assess the reliability of three diagnostic methods (near-infrared transillumination (NIRT), bitewing radiographs (BW), and clinical images (CI)) to detect occlusal carious lesions in a low caries risk population. This retrospective analysis included one hundred and eighty-eight occlusal surfaces, scored as sound surface, early lesion, or distinct lesion. We evaluated the agreement between and within the methods over time. Kappa statistics tested the correlation between the methods. Examiners detected occlusal early lesions more frequently with visual examination and NIRT and the same lesions were confirmed on the 2-year follow-up. Within the limitations of this study, we were able to establish that early occlusal lesions can be detected and monitored over time using NIRT and visual exam, while BW scores showed mostly sound surfaces at both examinations. NIRT combined with clinical examination can be considered appropriate to detect and monitor early enamel caries on the occlusal surface in low caries-risk populations.
摘要：
本研究的目的是评估三种诊断方法的可靠性(近红外透照(NIRT)，bitewing射线照片（BW），和临床图像（CI）），以检测低龋风险人群中的咬合龋病变。这项回顾性分析包括188个咬合面，评分为声音表面，早期病变,或明显的病变。随着时间的推移，我们评估了这些方法之间和内部的协议。Kappa统计检验了方法之间的相关性。检查人员通过目视检查和NIRT更频繁地发现咬合早期病变，并且在2年的随访中证实了相同的病变。在这项研究的局限性内，我们能够确定早期咬合病变可以检测和监测随着时间的推移使用NIRT和视觉检查，而BW评分在两次检查中都显示出主要的声音表面。NIRT结合临床检查可以认为适合于低龋风险人群的咬合面早期釉质龋的检测和监测。
