对49例晚期慢性牙周炎患者的切牙、尖牙和前磨牙进行初步的非手术牙周治疗。每3个月在每颗牙齿的6个位点通过探测附着水平测量来监测结果。在24个月的时间内，对每个部位的一系列9个探测附着水平测量值进行线性回归分析。回归线的斜率，24个月期间预计的探测附着丧失。间隔（Δ.γ）并计算了每个地点的坡度概率水平。鉴定了两组具有探测附着损失的位点：组1：具有Δ的位点。γ的> 1.5 mm且P < 0.05;组2：具有Δ的部位。γ的> 1.0 mm，P < 0.05。第1组包括120个研究中心（5%），第2组包括265个研究中心（10%），共2532个可用研究中心。在两组中，对于初始探测深度≤的位点，探测附着丧失更频繁地被注意到。3.5 mm，比初始探测深度≥7.0在最初较浅或中等深度的病变中发现大多数具有探测、附着丧失的部位的发现可能表明由于与治疗相关的创伤而导致的附着丧失，而不是由于持续的炎性疾病过程而导致的附着丧失。
Incisors, cuspids and premolars in 49 patients with advanced chronic periodontitis were treated with initial, non-surgical periodontal therapy. The results were monitored by probing attachment level measurements at 6 sites of each tooth every 3rd mo. during a period of 24 mo. A series of 9 probing attachment level measurements for each site was subjected to linear regression analysis. The slope of the regression line, the projected probing attachment loss during the 24-mo. interval (.DELTA..gamma.) and the probability level of the slope were calculated for each site. Two groups of sites with probing attachment loss were identified: group 1: sites with .DELTA..gamma. > 1.5 mm and P < 0.05; group 2: sites with .DELTA..gamma. > 1.0 mm and P < 0.05. Group 1 included 120 sites (5%) and group 2 included 265 sites (10%) of the total of 2532 available sites. In both groups, probing attachment loss was more frequently noticed for sites with an initial probing depth .ltoreq. 3.5 mm than for sites with initial probing depth .gtoreq. 7.0 mm. The finding that the majority of sites with probing, attachment loss was found among initially shallow or moderately deep lesions may indicate attachment loss due to trauma associated with therapy rather than loss as a result of a continuing, inflammatory disease process.
