本研究试图确定过去牙周破坏的模式是否可以（1）简要总结，（2）与其他临床和微生物学参数相关。对61名年龄在12岁至61岁之间、患有破坏性牙周疾病的受试者进行了评估，每颗牙齿6个部位的发红、牙菌斑、化脓、探诊出血、牙槽深度和附着水平。计算每个个体的基线依恋水平测量值的频率分布。使用曲线拟合算法将频率分布拟合为1项、2项和3项正态分布。拟合的参数可以用来简明地总结所有的频率分布。3个主要模式的附着丧失可以区分。模式I需要一个两项分布，在< 34%的部位局部破坏，并进一步分为3组，这取决于患病部位的平均附着丧失。亚组的第二个峰的平均值分别为2.7、5.3和8.6 mm。模式II表现出更广泛的疾病（>33%的受影响部位），频率分布中有多个峰，需要3项分布才能获得满意的拟合。然而，很大一部分网站没有受到影响。模式III表现出单峰正态分布，几乎所有部位都受到影响。该组中峰的平均附着水平范围为2.7至8.4 mm。在每两个月一次的监测过程中，61例受试者中有23例在1个或多个部位显示出明显的附着丧失，这是通过公差分析方法确定的。龈下菌斑样本取自这些活动部位，并在治疗前与对照部位相匹配。第II组和第III组（广泛传播疾病组）受试者的活动部位和对照部位中，具核梭杆菌、中间链球菌和腐蚀艾肯氏杆菌的比例显著升高，而在更局限性疾病组I受试者的活动部位和对照部位中，伴放线放线杆菌和痤疮丙酸杆菌的比例升高。第I组受试者在Widman皮瓣手术和全身四环素治疗后牙周部位的危险率降低了13至15倍，而第II组和第III组受试者降低了2至6倍。
The present investigation attempted to determine if the pattern of past periodontal destruction could be (1) concisely summarized, and (2) related to other clinical and microbiological parameters. 61 subjects between the ages of 12 and 61 years with destructive periodontal disease were evaluated at 6 sites per tooth for redness, plaque, suppuration, bleeding on probing, pocket depth, and attachment level. The frequency distribution of baseline attachment level measurements was computed for each individual. A curve fitting algorithm was used to fit the frequency distribution to 1‐, 2‐, and 3‐term normal distributions. The parameters of the fit could be used to summarize concisely all of the frequency distributions.3 major patterns of attachment loss could be distinguished. Pattern I required a two‐term distribution with localized destruction at < 34% of sites and was further divided into 3 groups, depending on average attachment loss at diseased sites. The means of the second peak for the subgroups were 2.7, 5.3, and 8.6 mm, respectively. Pattern II exhibited more widespread disease (>33% of sites affected) with multiple peaks in the frequency distribution requiring a 3‐term distribution for satisfactory fit. However, a significant proportion of sites was not affected. Pattern III exhibited a single‐peaked normal distribution in which virtually all sites were affected. Mean attachment levels of the peaks in this group ranged from 2.7 to 8.4 mm.23 of the 61 subjects showed significant attachment loss at 1 or more sites during the course of bi‐monthly monitoring, as determined by the tolerance method of analysis. Subgingival plaque samples were taken from these active sites and matched with control sites prior to therapy. The proportions ofFuso‐bacterium nucleatum, Streptococcus intermedius, andEikenella corrodenswere significantly elevated in active and control sites of subjects in groups II and III combined (the widespread disease groups), and proportions ofActinobacillus actinomycetemcomitansandPropionibacterium acneswere elevated in active and control sites of the more localized disease group I subjects. Group I subjects showed a 13‐to 15‐fold decrease in hazard rates of periodontal sites after Widman flap surgery and systemic tetracycline, whereas groups II and III subjects showed 2‐to 6‐fold decreases.
