23 subjects were followed prior to treatment for 5 to 12 months in an attempt to relate attachment loss during this period to attachment level, probing depth, gingival redness and bleeding on probing. The subjects were divided into 3 groups based on amount and distribution of prior attachment loss: minor periodontitis, predominantly molar periodontitis and generalized periodontitis. The % of sites that exhibited attachment loss during the study period in the minor periodontitis, predominantly molar periodontitis and generalized periodontitis groups, were 1.3, 8.1 and 5.4, respectively. Subjects with minor periodontitis and predominantly molar periodontitis exhibited attachment loss more frequently in molar sites, proximal sites and sites with attachment level greater than or equal to 4 mm. In subjects with generalized periodontitis, attachment loss was related to tooth surface and attachment level, but not to tooth type. The relationship between the clinical parameters and attachment loss was improved compared with previous studies by using more homogeneous subject groups, more sensitive methods of analyzing attachment change and multivariate data analysis. However, the clinical parameters could not be used as diagnostic tests to predict attachment loss at individual sites.
在治疗前对23名受试者进行了5至12个月的随访，试图将这一时期的附着丧失与附着水平、探诊深度、牙龈发红及探诊出血联系起来。根据既往附着丧失的程度和分布情况，将受试者分为3组：轻度牙周炎组、主要为磨牙牙周炎组和广泛性牙周炎组。在研究期间，轻度牙周炎组、主要为磨牙牙周炎组和广泛性牙周炎组中出现附着丧失的部位百分比分别为1.3%、8.1%和5.4%。轻度牙周炎和主要为磨牙牙周炎的受试者在磨牙部位、邻面部位以及附着水平大于或等于4mm的部位更频繁地出现附着丧失。在广泛性牙周炎受试者中，附着丧失与牙面及附着水平有关，但与牙型无关。与以往研究相比，通过使用更同质的受试者群体、更敏感的分析附着变化的方法和多变量数据分析，临床参数与附着丧失之间的关系得到了改善。然而，临床参数不能用作诊断试验来预测个体部位的附着丧失。
