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+.
