Introduction: Recurrent aphthous stomatitis (RAS) is one of the most usual inflammatory diseases of the oral mucosa. The clinical characteristics of RAS are well defined, but the exact etiology and pathogenesis of the disease are not. Several investigations have noticed cigarette smoking to have a protective effect on RAS. The aim of the study is to investigate the association between cigarette smoking and RAS in order to improve the current knowledge on this issue.
Methodology 68 patients with RAS participated in the study. A full mouth clinical examination was performed and a medical history was taken for each patient. Data were analyzed with χ2 test.
Results While 6 (8.9%) of patients with RAS were smokers, a significantly higher percentage (24.9%) among the subjects with RAS were not smokers (group II) (χ2 =70.4; d.f. = 2, P < 0.001).
Conclusion The negative association between smoking and RAS indicated by this investigation is not meant to encourage people to smoke nor to spare them from the intention to quit their habit. These conclusions should be used to clear up the cause and pathogenesis of the RAS and to identify better prevention and treatment.
