The study group consisted of 62 female (69.7%) and 27 male (30.3 %) patients, with a mean age of 60.9 years, ranging from 40 to 89 years. In all cases a study protocol, specially designed for this disease was completed, including general, medical and oral information and an intraoral examination. Comparative and descriptive statistical analysis was performed. The Chi-square test was considered significant at p< 0.05. Results: The 50-59 years age group showed the highest prevalence among the studied cases (24.3%). The tongue was the most frequent location of symptoms, affected in 86 patients (96.6%). In addition to the burning sensation, 25.8% and 48.3% of the patients complained of oral dryness and dysgusia, respectively. Type III BMS was the most common subtype (50.6%).
