This study aimed to evaluate the diagnostic accuracy of an Optical Pulp Scanning (OPS) device. A total of 421 teeth from 107 emergency patients were investigated. Pulp vitality was assessed using conventional diagnostic methods (ConvDia), cold pulp testing (CPT), and a final diagnosis (FinDia) based on the pulp chamber contents (PCCs) of teeth requiring endodontic treatment (EmeTe). Following ConvDia, OPS screening was performed, endodontic access was prepared, and the FinDia was established. The specificity, sensitivity, as well as positive and negative predictive values of ConvDia, CPT, and FinDia were calculated against the OPS results. The null hypothesis stated that specificity and sensitivity would be equal to or lower than 90% and 80%, respectively. OPS sensitivity was 66.2% and 72.2% (EmeTe) for ConvDia, 66.2% and 69.8% (EmeTe) for CPT, and 76.9% for FinDia. Specificity was 26.4% and 25.5% (EmeTe) for ConvDia, 26.9% and 21.7% (EmeTe) for CPT, and 31.5% for FinDia. These results suggest that, at its current stage of development, the OPS device does not provide an acceptable level of diagnostic accuracy, particularly in vital teeth.
本研究旨在评估光学牙髓扫描（OPS）设备的诊断准确性。对107例急诊患者的421颗牙齿进行了调查。使用传统诊断方法（ConvDia）、冷牙髓测试（CPT）以及基于需要进行牙髓治疗（EmeTe）的牙齿的牙髓腔内容物（PCCs）的最终诊断（FinDia）来评估牙髓活力。在进行ConvDia之后，进行OPS筛查，准备牙髓治疗通路，并确定FinDia。根据OPS结果计算ConvDia、CPT和FinDia的特异性、敏感性以及阳性和阴性预测值。原假设表明特异性和敏感性将分别等于或低于90%和80%。对于ConvDia，OPS在EmeTe中的敏感性为66.2%和72.2%；对于CPT，在EmeTe中的敏感性为66.2%和69.8%；对于FinDia，敏感性为76.9%。对于ConvDia，特异性在EmeTe中为26.4%和25.5%；对于CPT，在EmeTe中为26.9%和21.7%；对于FinDia，特异性为31.5%。这些结果表明，在其当前的发展阶段，OPS设备不能提供可接受的诊断准确性水平，尤其是在活髓牙中。
