| Abstract (english) | 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 12mm 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+. |
