Abstract

Objectives: The aim of this study was to examine the association between depressive symptoms and periodontal diseases in a representative group of adults.Methods: A total of 4,892 subjects were included in the study. Periodontal disease was assessed using the Community Periodontal Index. The PHQ-9 scale was used to evaluate depression. Binary logistic regression analysis was used to calculate the Odds Ratio (OR) for periodontal disease with a 95% confidence interval (CI).Results: The prevalence of depressive symptoms was 93.4 in the normal group (PHQ-9≤9) and 6.6 in the group with depressive symptoms (PHQ-9≥10). On dividing the group with depressive symptoms by gender, the OR for periodontal disease was 1.13 (95% CI=0.82-1.56). On dividing the normal group by gender and educational level, the OR was 0.96 (95% CI=0.69-1.34). Thus, no significant difference was found between the groups.Conclusions: There was no association between depressive symptoms and periodontal diseases.
