Salivary cortisol and dehydroepiandrosterone as oral biomarkers to determine stress in patients with recurrent aphthous stomatitis.

BACKGROUND

Recurrent aphthous stomatitis (RAS) is one of the most common oral ulcerative diseases with a multifactorial etiology. Although psychological stress is an exacerbating factor, the role of salivary stress hormones, cortisol, and dehydroepiandrosterone (DHEA) in this oral disease has not been extensively reported. The study aimed to estimate and compare the salivary cortisol and DHEA levels in RAS patients and healthy control group with the aid of ELISA microplate reader.

SUBJECTS AND

METHODS

Sixty patients were enrolled in our study, which included 30 patients with clinically diagnosed RAS and 30 healthy controls. Two mL of unstimulated whole saliva was collected and salivary cortisol and DHEA levels were measured using ELISA kit, and the values were read by microplate ELISA reader and recorded in both groups.

RESULTS AND

CONCLUSION

The mean salivary cortisol and DHEA levels were elevated in the RAS patients compared to the healthy controls and were statistically significant. Salivary cortisol and DHEA can serve as oral biomarkers to determine stress in patients with RAS. However, the present study necessitates further studies with larger sample size and an improved protocol to ascertain the actual role of these presumed oral biomarkers as well as anxiety and stress as triggers in the pathogenesis of RAS.
