The aim of this study was to assess the possibility of digital image analysis of pit-and-fissure discoloration in order to diagnose caries. Digital images showing pit-and-fissure discoloration in 100 teeth of 19 patients were analyzed to obtain the fractal dimension (FD) and the proportion of the area of pit-and-fissure discoloration to the area of occlusal surface (PA). DIAGNOdent values were measured (DD), and dentists' diagnoses were also obtained. The sensitivity and specificity of FD, PA, DD, and the combination of FD and PA compared to the dentists' diagnoses were calculated. The sensitivities of FD, PA, DD, and the combination of FD and PA were 0.89, 0.47, 0.69, and 0.86, respectively, and the specificities were 0.84, 0.95, 0.91, and 0.86, respectively. Although further research is needed for the practical use, it is possible to use the analysis of digital images of pit-and-fissure molar discoloration as a diagnostic tool.
本研究的目的是评估利用数字图像分析窝沟变色以诊断龋齿的可能性。对19例患者100颗牙齿的窝沟变色数字图像进行分析，以获得分形维数（FD）和窝沟变色面积与咬合面面积的比例（PA）。测量了DIAGNOdent值（DD），并获取了牙医的诊断结果。计算了FD、PA、DD以及FD与PA组合相对于牙医诊断的敏感性和特异性。FD、PA、DD以及FD与PA组合的敏感性分别为0.89、0.47、0.69和0.86，特异性分别为0.84、0.95、0.91和0.86。尽管实际应用还需要进一步研究，但利用磨牙窝沟变色数字图像分析作为诊断工具是可行的。
