Association of anxiety, age and oral health-related quality of life with periodontitis: A case-control study.

Objective: This case-control study evaluated the association of sociodemographic profile, mental health disorders and oral health-related quality of life (OHRQoL) with periodontitis.

Methods: Patients with periodontitis (PP, n = 50) and control patients (CP, n = 50) were allocated into 2 groups after a complete periodontal examination. Data collection included age, sex, marital status, education and application of 2 questionnaires: Hospital Anxiety and Depression Scale for the diagnosis of anxiety/depression and Impact Profile on Oral Health (OHIP-14) for classification of well-being. An adjusted multiple binary logistic regression analysis was performed to assess the effect of all studied covariates on periodontitis.

Results: The results show that mean clinical attachment loss and periodontal probing depth were 5.92 (SD = 0.42) and 5.46 (SD = 0.78) in PP and 0.00 (SD = 0.00) and 2.85 (SD = 0.23) in CP, respectively (p < 0.001). The regression analysis demonstrated a significant effect on periodontitis for age (OR = 1.13; p < 0.0001; 95% CI: 1.07-1.20), with the PP having more people aged 50 years or older than CP, anxiety (OR = 1.25; p = 0.020; 95% CI: 1.04-1.50) and OHIP-14 (OR = 1.17; p < 0.0001; 95% CI: 1.08-1.226).

Conclusions: The findings showed a positive association between anxiety, OHRQoL and age with periodontitis.
