Impact of oral lesions on the quality of life of psoriatic individuals: A case-control study.

OBJECTIVES

To assess the presence of oral lesions and the impact of oral health-related quality of life (OHRQoL) on individuals with psoriasis.

METHODS

This case-control study comprised 295 individuals with psoriasis and 359 controls. Oral examination to assess different types of oral lesions as angular cheilitis (AC), geographic tongue (GT), white (WP), and red plaque or red macule (RPM) was performed. To evaluate OHRQoL, the Oral Impact on Daily Performance (OIDP) questionnaire was applied. Data were analyzed using the chi-squared, Fisher, Kruskal-Wallis, Mann-Whitney, and Bootstrap Intervals tests.

RESULTS

Individuals with psoriasis had significantly more oral lesions than controls (OR = 3.66, 95% CI: 2.33-5.85; p < .001) and higher global OIDP scores (12.17 case versus 6.93 controls; p = .008). Higher occurrence of GT (p < .001) and AC (p < .001) was observed in individuals with psoriasis. The final multivariate model demonstrated higher OIDP scores related to the following variables: alcohol use, diabetes, anxiolytics use, AC, and GT, showing worse OHRQoL.

CONCLUSION

Psoriatic individuals had a higher frequency of AC and GT than controls. Worse OIDP scores in frequency and severity were observed in psoriatic individuals with oral lesions, revealing the negative impacts of these lesions on OHRQoL.
