Burning mouth syndrome (BMS) is a frequent source of oral discomfort and sensation mainly at middle-aged or elderly women without identifiable local pathology. Forty-two patients with stomato-glossopyrosis were registered at the Department of Periodontology, Dental School, University Pécs, between August 2002 and January 2003. Oral clinical examination failed to identify physical explanation for the complaint of painful or burning mouth. After complete examination (blood test included), scaling, root planning and oral hygiene instructions were given. Six patients reported decreasing mucosal pain or burning. Two patients had iron-deficiency and Sjögren's syndrome was suspected and verified at another two patients. Thirty-two patients completed the benzydamine-study. They were divided into two groups. The study group (16 patients) rinsed with benzydamine containing solution, the control group (16 patients) received placebo solution for rinsing the same way for ten days. Differences were found between the two groups favouring the benzydamine containing solution. Pain reduction, mouth dryness and diminution of burning sensation were detected by means of visual analog scale (VAS). Benzydamine rinses could be effective in the management of BMS, but clinicians need to monitor patients for possible side effects in the case of long-term use.
