A double-blind placebo-controlled trial is conducted in order to evaluate the efficacy of Diazepam 1% oral gel and determine the statistical significance of the outcome variables. 40 patients with BMS, in two groups:~case group with Diazepam 1% oral gel (Galenic formulation)~control group with placebo in oral gel formulation~Follow-up of 2 months
Burning mouth syndrome (BMS) is a syndrome characterized by burning and persistent oral pain, ranging from mild to intense, in the absence of organic disorders of the oral cavity and with a major impact on the quality of life of the sufferer. Although several etiological theories have been proposed to explain BMS, none has been universally accepted to date, and its origin remains unclear. Currently, several scientific evidences would suggest that underlying BMS would be alterations in certain neuropathic mechanisms.~The purpose of the study is to evaluate the efficacy of Diazepam 1% oral gel in the treatment of burning mouth syndrome.
