The reliability of an electronic detector for caries in pits and fissures was tested by means of physical measurements, histological sections and clinical evaluation. The device measures the ohmic resistance of the tooth, technical data are given. First we compared measurements and histological sections of teeth due for extraction. The results indicated a high sensitivity of the device for caries, false positive diagnoses did not occur. Based on this, a clinical evaluation on 179 teeth was performed. Under practical conditions the sensitivity of the electronic detector (0.77) was lower than in the first part of the study; conventional diagnosis revealed more carious lesions in dentine (sensitivity: 0.82).
通过物理测量、组织学切片和临床评估对一种用于检测窝沟龋的电子探测器的可靠性进行了测试。该设备可测量牙齿的欧姆电阻，并给出了技术数据。首先，我们比较了即将拔除牙齿的测量结果和组织学切片。结果表明该设备对龋齿具有高敏感性，未出现假阳性诊断。基于此，对179颗牙齿进行了临床评估。在实际情况下，电子探测器的敏感性（0.77）低于研究的第一部分；传统诊断发现牙本质中的龋损更多（敏感性：0.82）。
