Association of burning mouth syndrome with xerostomia and medicines.

OBJECTIVE A case control study to identify risk factors for burning mouth syndrome (BMS). MATERIAL AND METHODS Quantitative analysis was carried out on the total salivary flow at rest and stimulated; subjective xerostomia, ingestion of medicines and the psychological states of anxiety and depression in 40 patients with BMS and 40 controls. RESULTS The ANOVA analysis showed significant differences in the means of the number of medicines/day, number of xerostomising agents/day, subjective xerostomia, anxiety and depression, between the groups studied. No significant differences were seen in the at rest or stimulated saliva flow rates. The odds ratio analysis determined the association of BMS with xerostomia and the consumption of hypotensives and diuretics. CONCLUSIONS From the results of this study, it can be shown that the consumption of hypotensives and diuretics was a risk factor for the development of BMS. The function of the salivary glands in patients with BMS is not affected.
