Etiopathogenic, clinical-diagnostic and therapeutic aspects of the burning mouth syndrome. Research and treatment protocols in a patient group

Burning mouth syndrome (BMS) is a frequently seen pathology characterised by burning tongue and oral pain without macroscopic structural lesions to the mucose. BMS etiopathology isn't known and therapy is merely empirical and unsatisfactory. METHODS: To evaluate the hypothesis that this syndrome would originate by a small diameter peripheral neuropathy combined to a mucosal trophic lesion, 37 patients, (7 male, 30 female, between 36 and 79 years, mean 54 years) affected by BMS, consecutively observed in our dispensary were submitted to a series of examinations and to therapeutical approach used in neuropathic painful syndromes. All patients were submitted to a complete stomatological exam and X-ray pantomography to exclude mucosal macroscopical lesions and dentistry illnesses. All patients executed sierological exams (glycemia, etc.), neurological exam, tongue and foot dorsum quantitative sensory examination, tongue and face telethermography. A few patients (3 male, 10 female; age 34 to 53, mean 49) were submitted to mucosal tongue biopsy, analyzed by optic microscopy and immunofluorescency following treatment with anticytoplasmatic neuronal proteins antibodies (protein gene product 9.5). RESULTS: These examinations showed subclinical polyneuropathy in 50% of patients. In particular, a loss of function in small diameter nervous fibres in about 50% of patients was observed. Histological examination of tongue mucose revealed a moderate atrophy in 70% patients. CONCLUSIONS: All patients were submitted to an antalgic therapy, with non-antiflammatory drugs used in neuropathic painful syndromes (quercetine, antiepileptic drugs benzodyazepinein and gabaergic, topical application of capsaicine solutions).
