Zinc sulfate supplementation for treatment of recurring oral ulcers.
Use of zinc sulfate in promotion of wound healing and in maintenance of epithelial integrity suggested its possible use in the treatment or prevention of recurrent oral ulcers. In a series of 32 patients with recurrent aphthous ulcers (RAU), serum zinc levels were observed. Seventeen patients, eight with initial serum zinc levels above 110microng/dl and nine with serum zinc levels below 110microng/dl, were provided zinc sulfate supplementation up to a total of 660 mg/day. All patients with initial serum zinc levels less than or equal to 110 microng/dl showed improvement; three of the eight patients with initial serum zinc levels above 110 microng/dl improved, five did not. Improvement consisted of 50% to 100% reduction in frequency of episodes. This suggests a combination of causes of RAU, one of which may be a local or general deficiency of zinc or a defect in metabolism, perhaps at the cellular level, related to zinc.
