Abstract :
Background: Oral lichen planus (OLP) and oral lichenoid reactions (OLR) are related to systemic diseases and drug exposure. Long-term use of inhaled corticosteroids and ??-agonists in bronchial asthma (BA) may lead to the development of such oral lesions.Aim: To determine the prevalence and clinical correlation of asymptomatic OLP and OLR in individuals with BA.Materials and Methods: This case–control study included 280 participants. All were adults aged >18 years; those with systemic disorders, pregnancy, lactation, or tobacco habits were excluded. Asthma severity was graded using pulmonary function. Data were analyzed using SPSS 23.0 with t-test, ANOVA, chi-square, and correlation, considering p < 0 p?=?0.0019),>18 years; those with systemic disorders, pregnancy, lactation, or tobacco habits were excluded. Asthma severity was graded using pulmonary function. Data were analyzed using SPSS 23.0 with t-test, ANOVA, chi-square, and correlation, considering p < 0.05 significant..Results: Asthma patients showed significantly higher prevalence of oral lesions: 26.43% (37/140) had OLP (20%) or OLR (6.43%) versus 3.57% (5/140) in controls (p?
