Background, aims: The present study was undertaken to assess the periodontal status of a rural Japanese population and to study the correlation between the periodontal status and the serum antibody titers for Porphyromonas gingivalis (Pg) fimbriae.Method: A total of 236 individuals were examined for their periodontal conditions by the use of the community periodontal index for treatment needs (CPITN), and serum antibody titers for Pg fimbriae in their peripheral blood samples were evaluated using the enzyme-linked immunosorbent assay.Results: There was a substantially larger proportion of edentulous subjects in the age group older than 60 years. The remaining teeth were 24.1, 23.2, 11.1 and 10.1 per person in the 40–49, 50–59, 60–69 and 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:03036979:JCPE280311:ges" location="ges.gif"/〉70 age groups, respectively. The % of sextants with a CPITN code of missing sextant (MS) increased towards elderly and reached 〉60% in the age group of 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:03036979:JCPE280311:ges" location="ges.gif"/〉70 years, as the % of the CPITN 2, 1 or 0 sextant decreased. The % of CPITN 4 and 3 sextants did not differ between different age groups and were about 6–8% and 15–20%, respectively. The % of CPITN 1 or 0 sextants was higher in female subjects than in male subjects in the 60–69 and 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:03036979:JCPE280311:ges" location="ges.gif"/〉70 age groups, while the % of CPITN 4 or 3 sextants was higher in male subjects than in female subjects in all age groups. There was no significant difference between various age groups in the mean serum antibody titers for Pg fimbriae. The mean anti-Pg fimbriae antibody titers was significantly higher for the subjects with a maximum CPITN code 4 (max.-CPITN 4 subject) than for the subjects with lower maximum CPITN codes. The antibody titers varied extensively among the max.-CPITN 4 or 3 subjects, but not among the max.-CPITN 2/1/0 or MS subjects.Conclusions: The present study demonstrated that tooth loss is a remarkable event in elderly subjects and that oral prophylaxis and mechanical debridement should be mandatory in the population examined. It was also demonstrated that the serum antibody titers against Pg fimbriae could be useful for screening individuals with moderate to severe periodontitis.
