本研究调查了60名患者的1488颗牙齿对两种电牙髓测试和一种冷热牙髓测试的积极和消极反应。已知无牙髓或牙髓病变牙齿的三个亚组（接受根管治疗的牙齿，根管填充物的牙齿，或证实有相关根尖放射性的牙齿）被确定并分别评估其反应。测试在两个牙齿表面进行，面颌面和面颈部，以及所有修复体。每位患者的牙龈组织也使用两种电测试进行测试。主要发现是：(a)牙齿对冷无反应，对读数无反应或对读数大于组织对电的反应有很高的可能性属于已知的无牙髓或牙髓病变亚组；(b)在三个亚组中，唯一的假阳性反应是在多根牙齿中，可能至少有一个管中保留了重要组织；(c)在三个亚组中，如果将高于患者组织反应水平的电假阳性反应视为阴性反应，则冷和电假阳性的差异无统计学意义（p = 0.07）。
This study investigated the positive and negative responses of 1488 teeth in 60 patients to two electric pulp testers and a cold thermal pulp test. Three subgroups of known pulpless or pulpally diseased teeth (teeth receiving root canal therapy, teeth with root canal fillings, or teeth with confirmed associated apical radiolucencies) were identified and their responses evaluated separately. Testing was performed on two tooth surfaces, the facio-occlusal and faciocervical, and on all restorations. The gingival tissue of each patient also was tested using both electrical tests. The primary findings were: (a) teeth not responding to cold and either not responding or responding at readings greater than the tissue response to electrical had a high probability of being in the known pulpless or pulpally diseased subgroups; (b) the only false positive responses to cold in three subgroups were in multirooted teeth with probable vital tissue remaining in at least one canal; and (c) in the three subgroups, if the false positive responses to electrical that responded at levels higher than the patient's tissue response were considered to be negative responses, the difference in false positives between cold and electrical became not statistically significant (p = 0.07).
