To correlate the DIAGNOdent readings (LF) with those of direct visual (DV) examination, indirect visual (IDV) examination, bitewing radiography (BWR), and pit and fissure opening (PFO) for the detection of occlusal caries in primary teeth; to determine the validity of this device using PFO as reference; and to evaluate its reliability.
Two calibrated operators examined 130 teeth with 405 examination sites using DV, IDV and radiographic examinations, and LF. Of the 405 sites, 155 were visually scored for caries after pit and fissure opening.
Pit and fissure opening was found to significantly correlate with all methods (rhoLF = 0.48, rhoBWX = 0.48, rhoDV = 0.44, rhoIDV = 0.41). For enamel lesions, higher sensitivity (0.76) was found with DV, while higher specificity (0.88) with the LF. For lesions into dentin, however, higher sensitivity (0.78) was found with the LF, while higher specificity (0.98) with the BWR. The device's accuracy was found to be 0.61 for enamel lesions, while for lesions into dentin 0.70, and its reliability was excellent (ICC = 0.97).
The LF device presented high reliability in the detection of occlusal caries in primary teeth and its performance was similar to DV and radiographic examinations.
将DIAGNOdent读数（LF）与直接视觉（DV）检查、间接视觉（IDV）检查、咬合翼片X线摄影（BWR）以及窝沟开口（PFO）检查结果进行关联，以检测乳牙咬合面龋；以PFO为参照确定该设备的有效性；并评估其可靠性。
两名经过校准的操作人员使用DV、IDV、X线摄影检查以及LF对130颗牙齿的405个检查部位进行检查。在405个部位中，155个部位在窝沟开口后进行了龋齿的视觉评分。
发现窝沟开口与所有方法均显著相关（rhoLF = 0.48，rhoBWX = 0.48，rhoDV = 0.44，rhoIDV = 0.41）。对于釉质病变，DV的敏感性较高（0.76），而LF的特异性较高（0.88）。然而，对于牙本质病变，LF的敏感性较高（0.78），而BWR的特异性较高（0.98）。发现该设备对釉质病变的准确性为0.61，对牙本质病变的准确性为0.70，其可靠性极佳（ICC = 0.97）。
LF设备在乳牙咬合面龋的检测中具有较高的可靠性，其性能与DV和X线摄影检查相似。
