摘要：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 probing in lower right sextant (25.45%, p sextant (48.19%, p more often in lower anterior sextant (31.87%, p sextants are without teeth in 18–20.5% of cases, but lower anterior sextant in only 7.73% (p present in upper anterior sextant (21.2%, p often in lower anterior sextant (25–43%, p 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+.
