The accurate and reproducible measurement of gingival attachment level is essential for studying the progression of periodontitis in human populations. An automated periodontal probe has been developed which measures gingival attachment level using the occlusal or incisal surface of the tooth as a fixed landmark and which transfers data directly to a computer. The probing force is adjustable and is regulated by changing the air pressure. A mercury level switch maintains uniform probe angulation during measurements. The reproducibility of measurements obtained with the automated periodontal probe was examined by making duplicate gingival attachment level measurements at 784 sites in 9 patients 1 week apart and comparing the difference between the paired values. A probing force of 0.30 N was used. There was no significant difference in the frequency distributions of measurement differences between either maxillary versus mandibular teeth or anterior versus posterior teeth. The data demonstrate that this device can be used to measure gingival attachment level without the need for stents or estimation of the level of the cementoenamel junction and that reproducible data can be obtained and automatically stored in a computer for subsequent analysis.
准确且可重复地测量牙龈附着水平对于研究人类牙周炎的进展至关重要。现已开发出一种自动牙周探针，它以牙齿的咬合面或切缘作为固定标记来测量牙龈附着水平，并将数据直接传输到计算机。探测力可调，通过改变气压来调节。一个汞柱式液位开关在测量过程中保持探针角度一致。通过在9名患者的784个部位相隔1周进行两次牙龈附着水平测量，并比较配对值之间的差异，来检验使用自动牙周探针获得的测量结果的可重复性。使用的探测力为0.30 N。在上颌牙与下颌牙之间或前牙与后牙之间，测量差异的频率分布没有显著差异。数据表明，该设备可用于测量牙龈附着水平，无需使用支架或估计釉牙骨质界的水平，并且可以获得可重复的数据并自动存储在计算机中以供后续分析。
