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: ...
علیرغم معرفی و بکارگیری روشهای متعدد بهنگام‌سازی ماتریس ضرایب مستقیم داده- ستانده در شش دهه گذشته، هنوز نکاتی از روشهای RAS و RAS تعدیل شده وجود دارند که در سالهای اخیر توجه تحلیلگران اقتصاد داده- ستانده را به خود معطوف کرده است. یکی از این نکات چالش برانگیز رابطه بین اطلاعات برونزا، برتر و یا اضافی بیشتر سال مقصد در روش RAS تعدیل شده و کاهش خطاهای آماری آن نسبت به RAS متعارف در بهنگام‌سازی ضرا...
renal artery stenosis (ras) is the most common cause of secondary hypertension. preliminary data indicate that aspirin renography with hippurate may be more sensitive for detection ras. in this study 20 patients with known or suspected ras underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mtc-dtpa. renal angiogra...
Background: Recurrent aphthous stomatitis (RAS) is among the most common oral lesions and pain is often the chief complaint of patients. The main etiology of RAS is unknown but several predisposing factors have been suggested. This study aims to assess the correlation of blood types (ABO/Rh) with RAS. Methods: We conducted this prospective screening study on 50 patients with RAS and 50 controls...

Background and purpose: Recurrent aphthous stomatitis (RAS) or oral aphthous are among the most common problems in adults. Stressful events could cause these ulcers. The purpose of this study was to determine the prevalence of recurrent aphthous stomatitis among students in Mazandaran University of Medical Sciences and its relationship with anxiety. Materials and methods: In this analytical cr...
Background and Aims: The purpose of the present study was to review the studies regarding serological and salivary oxidant / antioxidant status in patients with recurrent aphthous stomatitis (RAS). Materials and Methods: The literature was searched using key words RAS, Antioxidants, Saliva, Hematinic (s) and Hematinic Acid in the last 10 years, particularly the recent 3 years (2010-2013). A...
