The distribution of periodontal disease stages is not the same in both human jaws, parts of the same jaw or in different ages of life. In the sample of 2,730 sextants, 455 persons 15+ years of age, analysis of distribution of both periodontal disease and loss of attachment in jaw sextants in different age groups was made, using the Community Periodontal Index (CPI) and Loss of Attachment (LA). Statistical significance testing was checked using the Pearson Chi-Square-test with probability of 95%. Healthy periodontium is mostly found in upper anterior sextant (36%, p < 0.001), and bleeding on probing in lower right sextant (25.45%, p < 0.001). There is most calculus in lower anterior sextant (48.19%, p < 0.001), followed by upper posterior (15-17%). Deep pockets are more often in lower anterior sextant (31.87%, p < 0.001), and upper and lower posterior sextants are without teeth in 18-20.5% of cases, but lower anterior sextant in only 7.73% (p < 0.001). Cumulative minimal loss of attachment (0-3 mm) significantly is more often present in upper anterior sextant (21.2%, p < 0.001), while values 5-11 mm are more often in lower anterior sextant (25-43%, p < 0.001). Loss of attachment > or = 12 mm appears in only 1.4% present sextants and it is rear on left jaw side. Significant differences in distribution of both periodontal disease and loss of attachment appear in age 30+.
牙周疾病各阶段在人类的上下颌、同一颌骨的不同部位或不同年龄段的分布并不相同。在2730个牙区段样本（455名15岁及以上的人）中，使用社区牙周指数（CPI）和附着丧失（LA）对不同年龄组颌骨牙区段的牙周疾病和附着丧失分布进行了分析。使用概率为95%的Pearson卡方检验进行统计学显著性检验。健康的牙周组织大多见于上颌前牙区段（36%，p<0.001），而探诊出血多见于右下牙区段（25.45%，p<0.001）。下颌前牙区段的牙石最多（48.19%，p<0.001），其次是上颌后牙区段（15 - 17%）。深牙周袋多见于下颌前牙区段（31.87%，p<0.001），上颌和下颌后牙区段在18 - 20.5%的病例中无牙，但下颌前牙区段仅为7.73%（p<0.001）。累积最小附着丧失（0 - 3mm）显著更常见于上颌前牙区段（21.2%，p<0.001），而5 - 11mm的值更常见于下颌前牙区段（25 - 43%，p<0.001）。附着丧失≥12mm仅出现在1.4%的现有牙区段中，且在左颌侧较少见。牙周疾病和附着丧失的分布在30岁以上人群中出现显著差异。
