The aim of this study was to determine whether changes in probing attachment levels are related to subgingival spirochete or leukocyte counts in periodontal pockets. Following initial clinical recordings and therapy consisting of oral hygiene instruction and root debridement, the probing attachment levels of proximal sites of 120 single-rooted teeth in 7 patients were measured every 3 months for 12 months. The measurements of each site were subjected to regression analysis, which determined whether the site was deteriorating, improving, or non-changing. Subgingival washings were taken of 19 deteriorating, 22 improving, and 127 non-changing sites to determine the number and % of spirochetes and the number of leukocytes at each site. Improved probing attachment levels were associated with reduced numbers of spirochetes and leukocytes. However, the ranges of individual measurements of subgingival washing variables overlapped considerably between groups. Spirochete and leukocyte counts related better to the 12-month probing depths than to changes in probing attachment levels during the preceding 12 months. These findings suggest that none of the tested subgingival washing parameters are suitable indicators of changes in attachment levels on an individual site basis.
本研究的目的是确定牙周袋探诊附着水平的变化是否与龈下螺旋体或白细胞计数相关。在进行初始临床记录以及包括口腔卫生指导和根面清创的治疗后，对7例患者的120颗单根牙邻面部位的探诊附着水平每3个月测量1次，共测量12个月。对每个部位的测量结果进行回归分析，以确定该部位是恶化、改善还是无变化。对19个恶化部位、22个改善部位和127个无变化部位进行龈下冲洗，以确定每个部位螺旋体的数量和百分比以及白细胞数量。探诊附着水平的改善与螺旋体和白细胞数量的减少相关。然而，各组之间龈下冲洗变量的个体测量范围有相当大的重叠。螺旋体和白细胞计数与12个月时的探诊深度的相关性优于与前12个月探诊附着水平变化的相关性。这些发现表明，所测试的龈下冲洗参数均不适用于个体部位附着水平变化的指标。
