Background: Burning mouth syndrome is a condition of unknown etiology, characterized by burning symptoms on the otherwise clinically healthy oral mucosa. Central and/or peripheral neuropathy is one of the proposed causes for this condition. Psychological component in these patients is also very present, as it is known that BMS patients exhibit high levels of pain, anxiety, and depression. The aim of this study was to evaluate anxiety and depression among patients with burning mouth syndrome and a control group. We also further review and discuss the literature available on this subject.
Subjects and methods: A total of 93 subjects, divided into two groups, participated in this study. The group of patients with BMS included 43 participants, while the control group consisted of 50 participants. Self-reported STAI (State anxiety and Trait anxiety) and BDI questionnaires were used to evaluate anxiety and depression in subjects in both groups.
Results: BMS group had higher average total scores of state anxiety, trait anxiety and depression. The difference between the BMS group and control group was statistically significant for state anxiety scores and BDI scores.
Conclusion: We might conclude that BMS patients are more anxious (state) and depressed when compared with the control group. However, they do not differ from the control group regarding anxiety as a trait. Thus we might conclude that feeling of anxiety in general starts after the BMS symptoms first occur and last for a longer period of time.
