ABSTRACT Recurrent Aphthous Stomatitis (RAS) may be part of the "atopic background". Recently it has been reported that aphtous stomatitis could be an expression of atopic diathesis. The aim of this study is to verify whether the prevalence of posttraumatic aphthae is higher in patients with RAS and atopic diathesis than in patients with RAS without atopy.
In the past three years 39 new patients between 14 and 56 years of age and affected by idiopathic RAS have been observed. Atopic status and history of posttraumatic aphthosis were evaluated in all patients.
The results appear to show that in our population the prevalence of posttraumatic aphthae is higher among atopic patients.
Not only RAS but also pathergy could be considered an expression of the rich clinical/ symptomatic constellation of atopic diathesis.

    ABSTRACT: Recurrent aphthous stomatitis (RAS; recurrent aphthous ulcers; canker sores) belongs to the group of chronic, inflammatory, ulcerative diseases of the oral mucosa. Up to now, the etiopathogenesis of this condition remains unclear; it is, however, considered to be multifactorial. The results of currently performed studies indicate that genetically mediated disturbances of the innate and acquired immunity play an important role in the disease development. Factors that modify the immunologic response in RAS include: food allergies, vitamin and microelement deficiencies, hormonal and gastrointestinal disorders (e.g., celiac disease, Crohn's disease, ulcerative colitis), some viral and bacterial infections, mechanical injuries and stress. In this paper, we presented the main etiopathogenetic factors of RAS with a special emphasis on the mechanisms of the immune response modification. Moreover, we discussed the crucial clinical symptoms and types of RAS together with epidemiologic data based on the current medical literature reports and our own observations.
