Abstract:
Radial immunodiffusion technique was used to estimate salivary immunoglobulin A, and enzyme-linked immunosorbent assay for estimation of serum IgA, IgG and IgM in 30 patients with acute recurrent aphthous ulceration (RAU) and during remission period compared to 30 healthy controls. Significantly elevated level of salivary IgA (p < 0.05) was found in patients with minor RAU when compared to the control group. Serum IgA level was elevated in patients with minor acute RAU when compared to the controls (p < 0.05). Serum immunoglobulin level of IgG and IgM showed no differences between patients with either minor or major recurrent aphthous ulceration and controls.
