Prevalence of recurrent aphthous ulceration in gizan

Abstract

Among present ulcers, recurrent aphthous ulceration (RAU) was found in 1.59% of 4,255 adult Saudi patients seen in the Dental Department, King Fahd Central Hospital, Gizan, between 1984-1989. Of all the patients examined including those with ulcers, 16.4% gave positive history of developing aphthus ulcers at least once during the two years previous to the time of examination. The highest prevalence for both present ulcers and history of ulcers was among the younger age-groups. No significant difference was found between the prevalence figures of RAU in the two sexes. None of the common triggering factors were contributary, nor there has been any correlation between smoking and RAU in this study.
