Psoriasis and oral health in adult United Statues population: A cross-sectional study

Abstract

Abstract Objectives The results were inconsistent with the association between psoriasis and periodontitis. To better understand the strength and nature of the association between oral conditions and psoriasis by analysis of a large number of adults in the United States. Methods By using The National Health and Nutrition Examination Survey datasets from 2009 to 2014, we performed a cross-sectional analysis. For participants aged ≥ 30 years, the psoriasis status was assessed from the medical questionnaire. We used data from periodontal and oral examinations to assess the oral conditions of our participants. We examined the association between psoriasis as exposure and moderate/severe periodontitis and non-functional dentition as outcomes. Results The weighted prevalence of psoriasis was 3%, 44% for moderate/severe periodontitis, and 20.5% for non-functional dentition. The fully adjusted model showed no significant association between psoriasis and moderate/severe periodontitis (Prevalence Ratio 1.03, 95% CI 0.9–1.2, p = 0.7). There was no statistically significant association between psoriasis and non-functional dentition except in the fully adjusted model it became statistically significant (Prevalence Ratio 0.8, 95% CI 0.7–0.9, p = 0.04). Conclusion Psoriasis was associated with the lower prevalence of non-functional dentition after adjustment of potential confounders but was not associated with the higher prevalence of moderate/severe periodontitis.
