A Case Series-Smokeless Tobacco Induced Oral Premalignant Lesions

Wide spectrum of oral mucosal lesions can be caused by tobacco in any form. Tobacco use causes an array of changes in the oral cavity, from mucosal pigmentation to thickening, ulceration of the epithelium. Oral cancer and other oral mucosal lesions such as tobacco induced keratosis, leukoplakia, and submucous fibrosis are strongly associated with tobacco consumption. The prevalence and severity of lesions demonstrate a dose-response relationship, which is best predicted by the amount, frequency and duration of smokeless tobacco use.
