Among the psoriasis patients surveyed, those who rated their gum health as poor or very poor generally exhibited a significant increase in the severity of their psoriasis symptoms. Furthermore, psoriasis patients who experienced difficulties with their speech because their dental trouble also experienced increased in their perceived psoriasis severity. Interestingly, patients who reported eating healthier diets with at least one serving of fresh fruit per day experienced mild psoriasis symptoms in comparison to patients who did not have these healthy dietary practices.
This study has several limitations, including the fact that results are based on a small cohort of patients. Furthermore, data was collected from retrospective surveys which is plagued by recall bias. Another limitation is that patients included in the study were receiving treatment in a dermatology clinic, meaning all patients who did not seek treatment for their psoriasis were excluded which may have led to a selection bias.
The take home message from the results of this study is that there is preliminary data arguing that oral self-care, oral hygiene and eating fresh fruit may benefit patients with psoriasis. However, due to the limitations of this study, further research is necessary to confirm the authors findings. In the meantime, suggesting healthy eating habits and oral hygiene in addition to the usual exercise and weight loss to complement treatment in psoriasis patients appears to be a reasonable practice.
