Journal of Oral Pathology & Medicine, 07/15/2010

Zinc deficiency might play a role in some patients with BMS. In such patients, appropriate zinc replacement therapy is effective in relieving symptoms. Of the 276 patients with BMS, 74 had low serum zinc levels. Zinc replacement therapy lowered the mean numerical pain scale in these patients from 8.1 to 4.1, compared with a mean decrease from 7.7 to 6.7 in a control group.
