The images of the Quantitative Light induced Fluorescent (QLF) device, which provides both natural color images similar to those from intraoral cameras and fluorescent images using 405 nm light in a single shot, were evaluated for the validity and inter examiner reliability in detecting tooth cracks. QLF images of 26 cracked teeth before and after removing crack lines were taken. Two examiners assessed the QLF images before removing the crack line with natural color images, fluorescent images, and combination images showing both images simultaneously, and recorded the crack's location after observing images. The reference standard of the crack's location was established by a trained dentist based on QLF images after removing the crack line. The agreement between examiners and the reference standard of the crack line was calculated by kappa value. Inter examiner agreement of natural color images showed at 0.394, while fluorescent and combination images showed at 0.449 and 0.493. Compared with the reference standard, the combination and fluorescent images showed higher agreement at 0.742 and 0.662, while the natural color images showed the lowest agreement, at 0.164. Determining crack location using only natural colored QLF images is challenging, but fluorescent and combination images improved agreement between examiners and the reference standard.
定量光诱导荧光（QLF）设备的图像可在单次拍摄中提供类似于口腔内相机拍摄的自然彩色图像以及使用405nm光的荧光图像，对其在检测牙齿裂纹方面的有效性和检查者间可靠性进行了评估。拍摄了26颗有裂纹牙齿在去除裂纹线前后的QLF图像。两名检查者在去除裂纹线之前，分别用自然彩色图像、荧光图像以及同时显示这两种图像的组合图像对QLF图像进行评估，并在观察图像后记录裂纹的位置。裂纹位置的参考标准由一名经过培训的牙医根据去除裂纹线后的QLF图像确定。通过kappa值计算检查者之间的一致性以及与裂纹线参考标准之间的一致性。检查者间自然彩色图像的一致性为0.394，荧光图像和组合图像的一致性分别为0.449和0.493。与参考标准相比，组合图像和荧光图像的一致性较高，分别为0.742和0.662，而自然彩色图像的一致性最低，为0.164。仅使用自然彩色QLF图像确定裂纹位置具有挑战性，但荧光图像和组合图像提高了检查者与参考标准之间的一致性。
