[Periodontal conditions and diabetes mellitus in the Japanese-Brazilian population].
OBJECTIVE
To evaluate the relationship between diabetic status and periodontal conditions in the Japanese-Brazilian population.


METHODS
The sample consisted of 1,315 subjects, of both sexes, first (Issei) and second (Nisei) generations, aged 30 to 92 years, living in Bauru, Brazil. Edentulism and presence of 6 null sextants were the exclusion criteria for the sample. The Community Periodontal Index and Periodontal Attachment Loss Index were determined using the probing of 10 teeth in a sample of 831 subjects. The diagnosis of diabetes mellitus was based on fasting blood sugar and blood sugar 2 hours after 75 mg of glucose overload. Statistical analysis was conducted using Kappa test and Chi-square test.


RESULTS
Regarding periodontal conditions, 25.5% of the sample were healthy people, 12.5% showed bleeding on probing, 49.4% calculus, 10.4% pockets of 4-5 mm deep, and 2.2% pockets deeper than 6 mm. The percentage of subjects with an attachment loss of 0-3 mm was 24.2%; 4-5 mm, 36.7%; 6-8 mm, 23.7%; 9-11 mm, 11.3%; and up to 12 mm or more, 4.1%. The association between the periodontal condition and diabetes mellitus showed no statistical significance (p<0.05), although diabetic subjects have a higher percentage of deeper pockets and attachment loss >6 mm than non-diabetics, as tested by Chi-square test.


CONCLUSIONS
Epidemiological studies relating oral health and systemic disease, such as diabetes mellitus, can provide important contributions for preventing the worsening of such diseases.
