recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...

BACKGROUND/AIM Recurrent aphthous stomatitis (RAS) is defined as multifactor immunologic inflammatory lesions in the oral cavity, characterized by painful, recurrent single/multiple, shallow, round or ovoid ulcerations of mucosal tissues. To date, a considerable number of RAS treatment protocols have been suggested, but since the etiology of RAS is idiopathic, these treatment options have sympt...

Recurrent aphthous stomatitis (RAS) and recurrent intraoral herpes (RIH) are the two most commonly presenting oral lesions in the dental setting. It is critical that the oral health professional be able to accurately discriminate between these disorders. To facilitate the differential diagnosis between RAS and RIH, important components of assessment are discussed. These include: prodromal signs...

Background: Recurrent aphthous stomatitis (RAS) is a common disease, which several etiologic factors have been considered for it. The infectious agents and immunological factors are the most suspected causes. Recently a few studies with varied results have been done to clarify the role of Helicobacter Pylori (H.pylori) in etiology of RAS. Objective: To find correlations between serum IgG and Ig...

Background and Aim: Recurrent aphthous stomatitis (RAS) is one of the most common lesions in the oral mucosa. The etiopathogenesis of RAS is not clear. RAS is multifactorial, and several factors can contribute to RAS development. This study aimed to evaluate the RAS prevalence and some related factors in 12-17-year-old schoolchildren in Zahedan City (Southeast of Iran). Materials and Methods: ...
