The purpose of this study was to locate the position of the periodontal probe tip using a pressure of 126 N/cm2 (force of 0.30N using a round periodontal probe tip with a diameter of 0.55 mm). The influence of gingival inflammation on this position was also studied. Subjects with three levels of periodontal health and disease were entered into the study and each contributed one experimental tooth. At each site a standardized probing system was used to place a probe into a clinical pocket. The probe tip was luted to the test tooth surface. The tooth with its gingival tissue and probe tip was extracted, fixed, and processed for histological measurements. Distances in mm were obtained from the cemento-enamel junction (CEJ) to the probe tip, to the base of the crevice/pocket, and to the most coronal connective tissue attachment. Analysis of the data indicated that clinical inflammation was not a factor in the placement of the probe tip at crevice/pocket's landmarks relative to the CEJ; however variability of probing may have caused the non-significance. The probing system placed the probe tip 0.66 mm apical to the base of the crevice/pocket and 0.06 mm coronal to the most coronal connective tissue attachment. These conclusions corroborated the results of the previous study in dogs which predicted probe placement of 0.44 mm apical to the base of the crevice using the standardized pressure of this probing system.
本研究的目的是使用126 N/cm²的压力（使用直径为0.55 mm的圆形牙周探针时力为0.30 N）来确定牙周探针尖端的位置。还研究了牙龈炎症对该位置的影响。将具有三种牙周健康和疾病水平的受试者纳入研究，每人提供一颗实验牙齿。在每个部位使用标准化的探测系统将探针插入临床牙周袋。将探针尖端粘固在测试牙齿表面。连同其牙龈组织和探针尖端一起将牙齿拔除、固定并进行组织学测量。获得从牙骨质-釉质界（CEJ）到探针尖端、到裂隙/牙周袋底部以及到最冠方结缔组织附着处的毫米距离。数据分析表明，临床炎症不是相对于CEJ在裂隙/牙周袋标志处放置探针尖端的一个因素；然而，探测的变异性可能导致了无显著性差异。该探测系统将探针尖端放置在裂隙/牙周袋底部根尖0.66 mm处以及最冠方结缔组织附着处冠方0.06 mm处。这些结论证实了先前在犬类中的研究结果，该研究使用此探测系统的标准化压力预测探针放置在裂隙底部根尖0.44 mm处。
