Oral Leukoplakia: Case Report

ABS TRACT The evaluation of the etiology of oral leukoplakia which is the most common premalign or potentially malign lesion of the oral mucosa. A 39-year-old male patient who complains to his gingiva was admitted to the clinic of periodontology. In his clinic examination, he has white lesions on the buccal mucosa and on his commisuras and also he has a tongue that was red, dry and with ragads. In his medical history, he addressed that because of his psychiatric disorder, he has been taking lithium for a long-term and has been smoking 50-60 cigarettes a day. Leukoplakia was determined in the bilateral buccal mucosa and labial commissure on his examination. Lesions were carried out by excisional biopsy. Smoking is the major etiologic factor for developing oral leukoplakia. Xerostomia resulted from using lithium for a long time may be considered as a triggering factor on the side of smoking in the development of oral leukoplakia in patients with bipolar affective disorder.
