Systemic Zinc Sulphate in Treatment of Recurrent Aphthous Ulcerations:A Doubleblind, Placebo Controled Study
Zinc Sulphate in Treatment of Recurrent Aphthous Stomatitis
Recurrent aphthous stomatitis (RAS) is one of the most common of oral mucosa diseases that affects approximately 20% of the general population. Despite the fact that clinical, pathologic and therapeutic feature of the disease has been comprehensively studied, the pathophysiology of aphthous ulcers remains incompletely understood.
Zinc is a potent catalyst of wound healing and zinc deficiency may be a common cause of delayed tissue repair. Use of zinc sulfate in promotion wound healing and preservation of epithelial integrity advocated its possible use in the treatment or prevention of recurrent oral ulcers.
The purpose of the present study was to determine of systemic zinc sulphate in the treatment of recurrent aphthous stomatitis.

Placebo Comparator: A
Patients with Recurrent aphthous stomatitis
|
patients with clinical signs and symptoms of RAS , in whom clinical diagnosis was accompanied with low level of zinc serum were selected for the study. Gender, age, medical history, symptoms, types and site, number, size, pain level, intervals, disease duration and form of treatment were recorded for all participants. Patients were randomly divided into two groups . The case group (n=7) received a single dose of zinc sulphate in the form of 220 mg capsules for 1 month ,while starch-containing placebo was administered with the same dosage and period in the control group. The clinical data were scored according to the size of lesions were scored subjectively. the symptomatology score was obtained using a visual analogue scale(VAS). All participants in both groups were examined up to 5 months in order to assess the effectiveness of the treatment. At the end of fifth month the serum zinc level was tested again. |
