- Nicotine stomatitis
Nicotine stomatitis is an oral pathologic condition that appears in the
hard palate of themouth as a whitelesion . It is not considered to bepremalignant and results fromtobacco smoking (especially pipes orcigar s) or long-term drinking of very hotbeverage s. Nicotine stomatitis should not be confused withreverse smoker's palate , which is a severe form of palatal keratosis and caused from smoking acigarette with the lit end inside the mouth.The cause of nicotine stomatitis is from the palate being exposed to very hot conditions.
Pipe smoking produces more heat on the palate than any other form of smoking. The frequency of this condition depends on a society's use of consuming hot beverages and of smoking in its various forms. More commonly found in men over 45 years of age, it is characterized as a "fissured" or "dried mud" appearance from excesskeratin production by cells. The palate may appear gray or white and contain manypapule s that are slightly elevated with red in their center. Furthermore, theteeth may be stained brown or black from tobacco smoke.Microscopically, epithelial cells of the palate exhibit signs of
hyperkeratosis and acanthosis. There may bemetaplasia of excretory ducts, which results in the visible papules if the ducts become hyperplastic.There is usually no treatment since there is no increased risk of
cancer . Immediate cessation of smoking may be advised in order to monitor lesion. Nicotine stomatitis should completely resolve on its own after 1 -2 weeks upon termination of smoking. If the lesion persists, abiopsy may be done to confirm diagnosis.References
