Blood Test Values and Community Periodontal Index Scores in Medical Checkup Recipients

Background: We examined the blood test values of people who received general medical checkups and their Community Periodontal Index (CPI) score. Methods: A total of 7,452 persons (5,742 males and 1,710 females), who had general medical and dental checkups, were the subjects of the study. Many were people who worked for companies in and around Nagoya and their family members, ranging in age from 16 to 80 years. The blood test in our study consisted of 37 items used in general blood tests. Partial‐mouth recordings were used to measure CPI scores. The highest CPI score for each subject was used for analysis. Odds ratios and confidence interval values were obtained using the Mantel‐Haenszel method to analyze the results. Results: CPI scores of 3 and 4 were related to the test values of high‐density‐lipoprotein cholesterol, serum iron, white blood cell count, fasting blood sugar, glycosylated hemoglobin A1, glycosylated hemoglobin A1c, and C‐reactive protein. Conclusion: Blood test values tended to show correlations with CPI scores, more clearly seen in males than in females. J Periodontol 2003;74:1778‐1784.
