Background: Oral lichen planus (OLP) is a chronic oral mucosal disease. It can manifest as severe erosive/ulcerative oral lesions, causing pain and discomfort. Oral health-related quality of life (OHRQoL) may be deteriorated due to the patient's symptoms. The aim of this study was to evaluate OHRQoL and its relation to oral pain in erosive/ulcerative OLP patients.
Materials and methods: In this cross-sectional study, patients with erosive/ulcerative OLP filled out Chronic oral mucosal disease questionnaire (COMDQ). Meanwhile, they recorded their oral pain through Visual analog scale (VAS). The Pearson's correlation coefficient was used to analyze the relationship between COMDQ score and VAS (IBM SPSS Statistics). P < 0.05 was considered statistically significant.
Results: Sixty patients participated in the present study; 51 (85%) were women and 9 (15%) were men. The mean age of participants was 50 ± 14.5 years. The mean score of COMDQ was 47.44 (±18.21). The mean VAS score was 4.5 (±2.4). COMDQ total and all domain scores were significantly correlated with VAS (P < 0.05), except for the "Patient support" domain (P = 0.63).
Conclusion: In patients with erosive/ulcerative OLP, there was a significant correlation between oral pain and COMDQ total score, as well as its physical, social, and emotional domains. It seems that COMDQ can be a complementary tool for assessing treatment outcomes in OLP patients.
