Objective:To study the correlation of the concentrations of tumor necrosis factor ?(TNF-?)between saliva and serum in patients with recurrent aphthous ulceration(RAU).Methods:Thirty patients with light RAU and thirty healthy controls were recruited.The levels of tumor necrosis factor ?(TNF-?)were measured in both saliva and serum of patients with RAU and control subjects by enzyme linked immunosorbent assay(ELISA)and TNF-? standard curve.Results:The concentrations of tumor necrosis factor ?(TNF-?)in saliva and serum were significantly higher(P
