OBJECTIVES: To know the most important clinical features of Burning Mouth 
Syndrome (BMS) in our environment.
MATERIAL AND METHODS: A prospective study of 30 BMS patients, 29 female and 1 
male, with a mean age of 60.2 years (range 37-89), was made. A previously 
designed clinical protocol, including blood counts, levadure culture, oral pH 
measurement and non-stimulated salivary flow rate, was completed by all 
patients. Comparative and descriptive statistical analysis was performed. The 
Chi-square test was applied (p< 0.05).
RESULTS: Moreover of a burning sensation, 60 % of patients presented oral 
dryness and 60 % dysgeusia. The tongue was the most frequent site affected of 
burning sensation (66.7 %). Type II of BMS was the most common (53.3%). In 
women, 82.9 % were postmenopausal. A 13.3 % of patients suffered type II 
Diabetes, 6.7 % vitamin deficiency and 56.6 % used xerostomy-inducer medication. 
The 56.6 % of patients showed chronic anxiety and/or depression. The 46.7 % had 
a deficient oral hygiene level and 44.4 % wore inadequate dentures. Salivary 
flow rate was decreased in 50 % of patients. Significant levadure growth was not 
detected in any case.
CONCLUSIONS: BMS patients in our environment are principally postmenopausal 
women, with tongue burning, xerostomy, dysgeusia and chronic anxiety and/or 
depression.
