Burning mouth syndrome (BMS) is a chronic disease characterized by burning of 
the oral mucosa associated with a sensation of dry mouth and/or taste 
alterations. BMS occurs more frequently among postmenopausal women. The 
pathophysiology of the disease is still unknown, and evidence is conflicting; 
although some studies suggest a central origin, others point to a peripheral 
neuropathic origin. The efficacy of some medications in the treatment of BMS 
suggests that the dopaminergic system may be involved.
