Oral lesions, were mostly asymptomatic (80.5%) and predominantly of reticulate pattern (87.9%). Avoidance of deram chewing induced marked or complete improvement of the oral lesions in 56.3% of cases even without treatment within a 3 month follow up period. Pathological examination showed features similar to classical LP.CONCLUSIONS: Deram chewing should be considered as a possible cause of oral LP, particularly among frequent and prolonged chewers.
