The aim of this study was to compare the level of agreement between four operators with different levels of experience for two methods of detecting secondary enamel and dentin carious lesions in composite restored teeth.
Sixty teeth of 40 patients with with secondary carious lesions in the composite resin were selected. The teeth were examined by two methods; visual inspection and a laser fluorescence device (DIAGNO dent pen 2190) by four operators including an undergraduate student, a dentist with 5 years of clinical experience, a general dentist with 12 years of clinical experience and an oral and maxillofacial radiologist. Cohen's kappa statistic was applied in order to assess the agreement between the diagnoses performed by the four operators with each diagnostic method.
The diagnosis performed by different operators achieved an excellent agreement with high ICC.
DIAGNOdent can be a useful device for secondary caries detection in posterior teeth as an adjunct to visual examination.
本研究旨在比较四位经验水平不同的操作者，使用两种方法检测复合树脂修复牙继发釉质和牙本质龋损时的一致性水平。
选取40例患有复合树脂继发龋损患者的60颗牙齿。由包括一名本科生、一名具有5年临床经验的牙医、一名具有12年临床经验的普通牙医和一名口腔颌面放射科医生在内的四位操作者，通过两种方法对牙齿进行检查；视觉检查和激光荧光装置（DIAGNOdent pen 2190）。应用Cohen's kappa统计量来评估四位操作者使用每种诊断方法所做出诊断之间的一致性。
不同操作者做出的诊断具有高度一致性，ICC值较高。
作为视觉检查的辅助手段，DIAGNOdent可成为检测后牙继发龋的有用工具。
