Factors involved in the remission of oral lichen planus treated with topical corticosteroids

Aim To determine the factors that affected the complete clinical remission of oral lichen planus (OLP) treated with topical corticosteroids. Material and methods We retrospectively evaluated the charts of patients diagnosed as OLP. Age, sex, current medical conditions, medications, type of OLP, Thongprasom score, pain level assessed by a numeric rating scale (NRS), Candida infection, topical steroid treatment preparation, duration of treatment until the first complete clinical remission, and follow-up duration were assessed as variables. Results In total 100 patients, after complete remission, 22 patients reported a relapse within 1.5–45 months, with a mean of 15.6 ± 13.2 months. Age, duration, gingiva and vestibule area, hypertension, dyslipidemia, Thongprasom score, preparation and topical corticosteroid potency were factors affecting the remission. Multivariate logistic regression analysis revealed that the patients’ age and duration of treatment were significant factors after adjusted for age, sex, and independent factors with a P -value
