Twenty-two anterior and bicuspid teeth that previously had been designated for extraction, were removed from 11 male patients. Two teeth were extracted from each patient and each tooth had a periodontal pocket of at least 4 mm and a Gingival Index of 2 or 3. One tooth in each patient was subjected to scaling, root planing, and plaque control in an effort to reduce gingival inflammation. By means of an orthodontic tube and composite resin bonding material a periodontal probe under 15 to 20 gm of pressure was fixed in the periodontal pocket of each tooth. The specimens were removed en bloc and histologic specimens prepared. The conclusions were that when the gingiva is inflamed, the tip of the periodontal probe tends to extend to the apical base of the junctional epithelium or slightly beyond but there is great variation in this position. Further, it was concluded that the position of the probe tip during probing is not affected by the depth of the sulcus or periodontal pocket.
从11名男性患者口中拔除了之前已确定要拔除的22颗前牙和双尖牙。每位患者拔除两颗牙齿，每颗牙齿的牙周袋至少为4毫米，牙龈指数为2或3。为了减轻牙龈炎症，对每位患者的一颗牙齿进行了龈上洁治、根面平整和菌斑控制。通过正畸管和复合树脂粘结材料，将在15至20克压力下的牙周探针固定在每颗牙齿的牙周袋中。将标本整块取出并制备组织学标本。结论是，当牙龈发炎时，牙周探针的尖端往往会延伸至结合上皮的根尖底部或略超出该范围，但该位置存在很大差异。此外，得出的结论是，探测过程中探针尖端的位置不受龈沟或牙周袋深度的影响。
