Clinical depression is associated with worse periodontal treatment outcomes
Summary
Subjects
The study included 697 of 1299 patients of the Kaiser Permanente NorthWest Division in Portland, Oregon, who had continuous eligibility for medical, dental, and pharmacy benefits and who had received an initial periodontal examination between Jan 1, 1996 and Dec 31, 1998, with at least 3 sites with probing depth ≥5 mm. Eighty five (12.2%) of patients had a diagnostic code for depression. The average at baseline for all patients was 24.5% of sites with pocket depths ≥5 mm, and the mean change from baseline to follow-up was 9.6%. Men and women were equally represented; 26% were current smokers, and mean age was 48.6.
Exposure
The exposure of interest was a DSM-IV diagnostic code for clinical depression prior to the periodontal examination.
Main Outcome Measure
A change score representing change in percent of sites with probing depth ≥5 mm was transformed into a dichotomous categorical variable representing the presence or absence of a submedian periodontal treatment outcome.
Main Results
In a multivariate logistic regression model, depression (odds ratio [OR] 2.16, 95% CI 1.12 to 4.16) and 4-month recall treatment (OR 2.34, CI 1.46 to 3.75) were associated with submedian periodontal treatment outcome, while percent of sites at baseline with PD ≥5 mm (OR 0.93, CI 0.91 to 0.94), number of remaining teeth at baseline (OR 0.94, CI 0.89 to 0.99), and number of teeth lost during the study period (OR 0.75, CI 0.58 to 0.96) were negatively associated. Periodontal surgery, age, sex, smoking, plaque, calculus, diabetes, and antidepressant medication were not significant in the model.
