ARDILA MEDINA, Carlos Martín; JIMENEZ GOMEZ, Raúl  e  ALVAREZ MARTINEZ, Efraín. Systematic revision of the effects of the reversed smoking habit on the oral mucosa. AMC [online]. 2013, vol.17, n.3, pp. 405-415. ISSN 1025-0255.

Background: It is been said that the reversed smoking habit intensifies the seriousness of the diseases of the buccal mucosa and put people at serious risks regarding oral health. Objective: to revise the scientific literature related to the diseases of the oral mucosa associated to reversed smoking habit. Method:  a systematic revision of observational and experimental investigations published in the Medline-PubMed and SciELO data bases from 1960 to 2012 was made. Terms were used in different combinations: nicotinic stomatitis, reverse smoking, reverse smokers, oral cancer, oral premalignant lesions y tobacco. Series of cases, duplicated results due to combinations of search terms, non-available data, letters to the editor and historical revisions were excluded. Results: in all the revised studies it was revealed that reversed smoking habit is more frequent in women than in men. Twelve investigations showed association between reversed smoking habit and carcinoma of the hard palate or microinvasive tumors. It was observed that inverted smokers are at more risk of presenting blotches and red areas in the palate, as well as leukoplakias and carcinomas. The estimated risk of presenting carcinoma of the hard palate was 132 times higher in women that have the reverse smoking habit. Mortality rates set by age were almost twice higher for reverse smokers compared to non-smokers. Conclusions: reversed smoking habit is associated to oral cancer and to other advanced diseases of the buccal mucosa. Intervention studies should be conducted in order to try to persuade populations to quit smoking.
