Increased anxiety level and high salivary and serum cortisol concentrations in patients with recurrent aphthous stomatitis.
Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal disorders. The aim of the study was to determine any association between anxiety levels and concentrations of salivary and serum cortisol in patients with RAS. It has been suggested that stress with its presumed effects on the immune system, constitutes one of the major causative agents of RAS. ⋯ The trait anxiety levels (STAI-T) were 49.78 (+/- 13.02) in RAS group and 38.49 (+/- 10.31) in control group (p = 0.001). Salivary and serum cortisol concentrations and state and trait anxiety levels in RAS were significantly higher than those in the control group. Our results suggest that stress may be involved in the pathogenesis of RAS.
