    <criteria>
      <inclusion_criteria>50 Patients between 20 and 45 years old will be included if they present with 1–5 aphthous ulcers of less than 24 h duration. The ulcers diameter will not be greater than 6 mm and they do not suffer from acute or chronic diseases of the oral mucosa Patients will be excluded from the study if they have concurrent clinical conditions including serious liver, kidney, and heart dysfunctions or if they have ulcers as a manifestation of a systemic disease process such as ulcerative colitis, Crohn’s disease, Behcet’s syndrome, or serious anaemia. To minimize the effect of confounding variables in the psycho- physiological component of the study, the patients should not have a history of alcohol or drug abuse and should not take any narcotic analgesics. Patients will be excluded if they have a history of systemic immunosuppressive therapy.</inclusion_criteria>
