目的比较DIAGNOdent、视觉和X线三种诊断系统对乳磨牙牙合面龋诊断的准确性和重复性。组织学金标准。材料和方法58个咬合面的乳磨牙依次检查由两名检查员使用三个诊断系统（DIAGNOdent，视觉和放射学）。将这些结果与组织学金标准进行比较。在一系列阈值下计算每个诊断系统的灵敏度和特异性。使用kappa统计量计算每个诊断系统的检查者间和检查者内重复性，主要结果测量每个诊断系统的敏感性、特异性、检查者间和检查者内重复性。（0.77和0.80，检查者1和2），然而，这被比所有其他系统更低的特异性（0.82和0.85）所抵消，除了检查者：1在V1视觉阈值。DIAGNOdent给出了最高值的kappa检查员内和检查员间的重复性与检查员内的重复性检查员2的视觉诊断有最高值的kappa.Conclusion的DIAGNOdent是最准确的系统测试乳磨牙的咬合牙本质龋的检测。DIAGNOdent系统的性能在统计学上并不显著优于使用非空化牙齿的目视检查（V1和V2阈值）。DIAGNOdent可能被证明是一种有用的预测性临床工具，然而，通过适当的培训，目视检查可以提供类似的结果，而不需要额外的设备。
Objective To compare the accuracy and repeatability of three diagnostic systems (DIAGNOdent, visual and radiographic) for occlusal caries diagnosis in primary molars.Design Two examiner, in vitro, blinded study. Histological gold standard.Materials and methods 58 occlusal surfaces of primary molars examined in turn by two examiners using each of three diagnostic systems (DIAGNOdent, visual and radiographic). These results were compared with a histological gold standard. Sensitivity and specificity were calculated for each diagnostic system at a range of thresholds. Inter- and intra- examiner repeatability were calculated for each diagnostic system using the kappa statistic.Main outcome measures Sensitivity, specificity, inter and intra examiner repeatability for each diagnostic system.Results The highest sensitivity values were provided by DIAGNOdent (0.77 and 0.80, examiners 1 and 2 respectively) however this was offset by a lower specificity (0.82 and 0.85) than all other systems with the exception of examiner: 1 at V1 visual threshold. The DIAGNOdent gave the highest values of kappa for intra- and inter- examiner repeatability with the exception of intra-examiner repeatability for examiner 2 where visual diagnosis had the highest value of kappa.Conclusion The DIAGNOdent was the most accurate system tested for the detection of occlusal dentine caries in primary molars. The performance of the DIAGNOdent systems was not statistically significantly better than that achieved using visual examination for non-cavitated teeth (V1 and V2 threshold). DIAGNOdent may prove useful as a predictive clinical tool, however with appropriate training visual examination may offer similar results without the need for additional equipment.
