MEDEIROS FOSSATI, Anna Christina et al. Alterations of the oral mucous membrane caused by the association between tobacco and the mouthwashes with an alcohol concentration of 26.9 %. Rev Cubana Estomatol [online]. 2006, vol.43, n.3, pp. 0-0. ISSN 1561-297X.

The epithelium and the keratin layer of the oral mucous membrane of 15 rats that were subjected to a topical application of cut tobacco and mouthwashes with an alcohol concentration of 26.9 % during 45 days were analyzed. After that period, the oral mucous membranes were removed and a histological analysis was made. It was observed a significant decrease of the thickness of the epithelium and of the keratin layer, which shows that cut tobbaco associated with collutories with a high concentration of alcohol causes the reduction of the thickness of the keratin layer and of the mouth epithelium.
