[Isolation of helicobacterpylori with PCR method from oral aphthous of patients with recurrent aphthous stomatitis in Rasht in 2002]

ABSTRACT

Introduction: recurrent aphthous stomatitis [RAS] is a disorder, which is characterized by ulcers restricted to oral mucousa. Regarding the inspection of histological similarities between peptic ulcers and recurrent oral aphthous and the response of RAS to the broad-spectrum antibiotic treatment such as tetracycline and the identified role of H.pylori in peptic ulcers, the possibility of bacterial involvement in the progression of oral aphtous ulcers has been suggested. Hence, there are limited evidence available for colonization of H. pylori and its probable role in induction of oral aphthouse ulcers
