The impacts of oral health symptoms, hygiene, and diet on the development and severity of psoriasis


Numerous studies have suggested a correlation between oral health, the oral microbiome, and various dermatologic conditions, particularly psoriasis. In this study, we utilize a specially designed questionnaire administered to 265 patients at The Ohio State University's dermatology clinics to explore the relationship between psoriasis and a combination of factors that included dietary habits, oral health, and oral hygiene practices. Age, family history of psoriasis, previous diagnosis of strep throat or rheumatoid arthritis, and oral pain or discomfort experienced within the last 12 months were all found to be significant predictors of psoriasis. Additionally, higher body mass index scores, poor gum health, and speech difficulties related to dental problems were all correlated with more severe psoriasis symptoms. Conversely, patients who reported consuming fresh fruit at least once a day experienced milder symptoms. Our goal is to develop a better understanding of how and why psoriasis incidence is correlated with some of the oral health factors under review.
