本研究的目的是确定扫频光源光学相干断层扫描（SS-OCT）在检测和估计后牙邻面龋深度的诊断准确性。从53名患者的86个近端表面获得了SS-OCT图像和咬翼片。6名检查者使用SS-OCT和X线片根据龋损深度量表（0-4）对位置进行评分。将结果与治疗后获得的临床观察结果进行比较。SS-OCT可以检测到存在的近端龋的断层图像合成的基础上获得的后向散射信号的近端龋病变通过咬合釉质。与X光片相比，SS-OCT在检测牙釉质空洞病变和牙本质龋方面显示出显著更高的灵敏度和更大的受试者工作特征曲线下面积（Student's t检验，p < 0.05）。对于临床环境中近端病变深度的检测和估计，SS-OCT似乎是一种比咬翼片更可靠和准确的方法。
The aim of this study was to determine the diagnostic accuracy of swept-source optical coherent tomography (SS-OCT) in detecting and estimating the depth of proximal caries in posterior teeth in vivo. SS-OCT images and bitewing radiographs were obtained from 86 proximal surfaces of 53 patients. Six examiners scored the locations according to a caries lesion depth scale (0-4) using SS-OCT and the radiographs. The results were compared with clinical observations obtained after the treatment. SS-OCT could detect the presence of proximal caries in tomograms that were synthesized based on the backscatter signal obtained from the proximal carious lesion through occlusal enamel. SS-OCT showed significantly higher sensitivity and larger area under the receiver operating characteristic curve than radiographs for the detection of cavitated enamel lesions and dentin caries (Student's t-test, p < 0.05). SS-OCT appears to be a more reliable and accurate method than bitewing radiographs for the detection and estimation of the depth of proximal lesions in the clinical environment.
