The role of psychological factors in the development of burning mouth syndrome.

The psychiatric profiles of 50 patients diagnosed with burning mouth syndrome (BMS) were compared to those of 50 age- and sex-matched individuals as the control group. The Symptom Checklist-90-Revised (SCL-90-R) questionnaire was used to evaluate the role of psychological factors in the development of BMS. Somatization, obsessive-compulsive, depression, anxiety, hostility, phobic anxiety, psychoticism, global severity index (GSI), positive symptom total (PST), and positive symptom distress index (PSDI) scores were significantly higher in the patients with BMS than in the control group. In a subgroup analysis according to sex, women with BMS had higher T-scores for somatization, obsessive-compulsive, paranoid ideation, GSI, PST, and PSDI than women in the control group. In contrast, only the PSDI score was significantly higher in men with BMS compared to men in the control group. There was a significant difference in the T-scores for somatization, psychoticism, and GSI between the three age subgroups (≤50, 51-65, and ≥66 years). The obsessive-compulsive and PSDI scores were significantly higher in patients with BMS who also had at least one chronic disease than in patients with BMS who had no chronic disease. In conclusion, psychological factors are correlated with BMS.
