Clinical Trial Summary

If epidemiological studies indicate relatively low prevalence reported in the general population, idiopathic burning mouth syndrome (BMS) is a common condition among certain groups of the population: 30% of menopausal women experience oral burning to varying degrees . Despite significant progress made in recent years, in understanding the physiopathogeny, treatment options remain limited and disappointing,resulting in an impairment of the quality of life. Given the chronic nature of idiopathic burning mouth syndrome, the need to identify the causes and effective treatment modalities for subjects suffering is essential.


Clinical Trial Description

Idiopathic burning mouth syndrome (BMS) is a chronic orofacial pain condition in which the pain is felt as intense, located on the tongue and the oral mucosa with no known cause. The pain may last for years and present treatments are of little effect. BMS is primarily a feminine disease, affecting women during or following menopause, suggesting an etiopathogenic role of the sexual hormones potentiating a local salivary factor. An anxiodepressive component is often associated with the disease. Recently, a molecule named opiorphin has been identified in human saliva. In animals, this molecule has shown potent analgesic properties comparable to those of morphine. The hypothesis of the investigators is that this molecule is in lower quantity in the saliva of persons suffering BMS and that this decrease causes oral burning sensations.

The main objective of the study is to test the hypothesis of a decrease of opiorphin levels in the saliva of patients suffering from primary BMS compared to a group of control subjects. The main judgment criteria is the level of salivary opiorphin in ng/mL.

The proposed study is a multicentric, simple blinded case controlled study. The investigators will collect the data from 21 primary BMS patients and 21 control subjects matched in sex, age, and hormonal status (menopause). The alpha risk is 0.5% and the power of the study is 90%.

Criteria for inclusion : BMS patients will be suffering for more than 4 months from burning pain in the tongue or oral mucosa with no organic trouble detectable by anamnesis, clinical evaluation and biological testing.

The design of the study includes three sessions for all subject of both groups; the maximum duration of participation for a subject is 8 weeks and the total duration of the study is 24 months There are two investigation centers. ;
