本研究比较了6个牙周探针（1个第三代、4个第二代和1个第一代）的相对附着水平（RAL）和可探测缝隙深度（PCD）。一个单一的临床医生记录RAL和PCD在6例慢性成人牙周炎患者（平均年龄48.2岁）在两次访问（间隔：1周）使用拉丁方检查顺序。在Ramfjord指数牙的4个邻间位点记录重复测量，以检查探针内差异。在装置11、26、31和46的相似部位记录额外的单次测量值，以研究穿刺针间差异。在> 94%的部位，探头内RAL和PCD再现性小于或等于1 mm。所有探头内Pearson相关系数均> 0.85（P = 0.00），探头间RAL和PCD一致性在> 49%的RAL部位和> 61%的PCD部位小于或等于1 mm。所有探针间Pearson相关系数均> 0.42 RAL（P = 0.00）和> 0.49（P = 0.00）对于PCD，方差分析显示第一代穿刺针和第二代穿刺针之间的RAL和PCD存在显著差异（P < 0.005）;第三代探针与第一、二代探针之间的RAL第三代探针与第一代和第二代探针之间的PCD（P = 0.0475）。在记录的大于或等于4 mm和大于或等于6 mm的囊袋百分比中，探头间差异具有临床意义。在RAL和PCD中发现了显著的探头间差异，这在数据解释和比较中具有临床意义。
THIS STUDY COMPARED RELATIVE attachment levels (RAL) and probeable crevice depths (PCD) from 6 periodontal probes (1 third, 4 second, and 1 first generation). A single clinician recorded RAL and PCD in 6 patients with chronic adult periodontitis (mean age 48.2 years) during two visits (interval: 1 week) using a Latin square examination order. Replicate measurements were recorded at the 4 interproximal sites of the Ramfjord index teeth to examine intra-probe differences. Additional single measurements were recorded at similar sites of units 11, 26, 31 and 46 to investigate interprobe differences. Intra-probe RAL and PCD reproducibility was less than or equal to 1 mm at > 94% of the sites. All intra-probe Pearson correlation coefficients were > 0.85 (P = 0.00), Inter-probe RAL and PCD agreement was less than or equal to 1 mm at > 49% of the sites for RAL and > 61% of the sites for PCD. All inter-probe Pearson correlation coefficients were > 0.42 (P = 0.00) for RAL and > 0.49 (P = 0.00) for PCD, Analyses of variance showed significant differences in RAL and PCD between the first generation probe and the second generation probes (P < 0.005); in RAL between the third generation probe and the first and second generation probes (P = 0.0354); and in PCD between the third generation probe and the first and second generation probes (P = 0.0475). Inter-probe differences were clinically significant in the recorded percentages of pockets greater than or equal to 4 mm and greater than or equal to 6 mm. Significant inter-probe differences were found in RAL and PCD which have clinical importance in data interpretation and comparison.
