Comparison of Salivary Cortisol and α-amylase Levels and Psychological Profiles in Patients with Burning Mouth Syndrome.

PURPOSE: The aim of the study was to compare salivary cortisol and α-amylase levels and psychological profiles in patients with burning mouth syndrome (BMS) and healthy subjects.

METHODS AND MATERIALS: Spitting method was used to collect unstimulated salivary. Salivary cortisol and α-amylase levels were determined using ELISA and the Caraway starch-iodine technique. SLC-90 questionnaire was used to determine the psychological profiles.

RESULTS: The difference between mean of salivary cortisol levels in patients with BMS and in healthy subjects was not significant (4.50 ± 3.68 ng/mL vs. 3.69 ± 3.07 ng/mL, p = 0.377). The difference between mean of α-amylase levels in the BMS patients and healthy subjects was significant (351.68 ± 142.5 and 146.22 ± 130.4, p = 0.001). Note that, 83.4% and 18% of the patients in the case and control groups had psychological problems (p = 0.001).

CONCLUSION: The results showed higher salivary levels of cortisol and α-amylase in patients with BMS compared to healthy individuals. Psychological problem was prevalent in patients.
