Oral leukoplakia (OL) is a premalignant lesion described as “a predominant white lesion of the oral mucosa which cannot be defined as any other known lesion”. Several clinical trials have investigated the treatment of OL with use of supplements. Although the administration of retinoic acid and beta-carotene has some efficacy to resolve OL, the studies were based on small samples and short periods of follow-up. Given the side effects and counterindications of antioxidizing agents, with the exception of lycopene, the use of agents requires careful control. The small number of patients, the lack of controls, the lack of widely accepted criteria for classifying OL, the variability in nonsurgical treatment protocols, and differences in histopathologic evaluation difficult the interpretation of data of the few randomized clinical trials in nonsurgical treatment of OL. At this time, randomized controlled trials for nonsurgical treatment of OL demonstrate no evidence of effective treatment in preventing malignant transformation and recurrence. It reinforces that after clinical resolution, OL should be regularly followed.
