The distribution of periodontal disease and loss of attachment in jaw sextants in different age groups--cross-sectional study.
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+.
