Oral burning sensation: prevalence and gender differences in a Japanese population.

BACKGROUND

Burning mouth syndrome (BMS) is characterized by an oral burning sensation (OBS) in the tongue or other oral mucous membrane in the absence of any clinical abnormal findings. It frequently affects middle-aged and aged women. Although there are many oral disorders with OBS besides BMS, the prevalence of OBS is unclear.

AIM

To investigate the prevalence of OBS and analyze the gender differences in a Japanese population.

METHODS

The study subjects were 2599 dental patients in two dental offices in Tokyo, Japan. The prevalence of OBS was investigated using a questionnaire.

RESULTS

The mean ages of the subjects were 42.7 +/- 13.8 (mean +/- SD) years of age in male and 40.1 +/- 15.4 (mean +/- SD) years of age in female. The prevalence of OBS "at present" was 2.8% of 1310 male subjects and 3.2% of 1289 female subjects. There was no statistically significant difference between them for each decade. The prevalence including "at present" and "in the past" were 9.3% in male subjects and 10.8% in female subjects; this difference was not statistically significant.

CONCLUSION

These findings fail to demonstrate a female predilection for OBS.
