title: Prevalence of recurrent aphthous ulceration in Jordanian dental patients.
abstract: BACKGROUND
  Reviewing the literature, no studies were cited to report the prevalence of recurrent aphthous ulceration in Jordan. The aim of this study is to report the prevalence of recurrent aphthous ulceration in Jordanian subjects.
  
  
  METHODS
  A total of 684 dental patients who attended Jordan University of Science and Technology interviewed and administered to fill questionnaires related to history, size, shape, and duration of recurrent aphthous ulceration. Other related questions were also asked.
  
  
  RESULTS
  About 78% of subjects experienced recurrent aphthous ulceration. Approximately 85% of ulcers were less than one cm in diameter, 66% were circular in shape, 92% were painful, 82% interfered with eating, and 55% located in lips and buccal mucosa. Only 50%of participants related ulcers to stress. Sixty eight percent reported no association with tiredness and 85% no association with types of food ingested. Of the 39% who had blood tests carried out, 7% had vitamin B12 and 4% hemoglobin deficiency.
  
  
  CONCLUSIONS
  Recurrent aphthous ulceration is a common problem in Jordanian adults.
