ORAL STIMULATION OF PATIENTS WITH BURNING MOUTH SYNDROME USING SINUSOIDAL CONSTANT CURRENT

Burning mouth syndrome (BMS) represents an oral pain disorder without the apparent lesions on oral mucosa. Genesis of BMS is still unclear, but neurological disturbances are highly suspected. The aim of this investigation is to compare the oral mucosal sensibility to sine wave constant current electrical stimulation between BMS patients and controls. The hypothesis that there is a possible alteration in reactibility in patients with BMS is tested. Participants are sorted in 2 groups: one consists of 37 BMS patients, and the other is control group with are 30 age and sex matched subjects. Current perception thresholds&#8217; testing was carried out on the tongue tip. For creating measurable sinusoidal constant current stimuli, we had produced sinusoidal constant current source. We performed tests at frequencies of 20, 200, 500 Hz, 2 and 5 kHz. We have used two active electrodes of different sizes comparison. BMS group had statistically significant lower current perception thresholds for any frequency and any active electrode applied (post hoc Scheffe multiple comparisons ; p<0.001 with smaller active electrode applied and p&#8804; 0.007 with larger active electrode applied), Sinusoidal constant current stimulation of oral mucosa showed somatosensory hyperfunction in patients with burning mouth syndrome, ascribing it a neurological origin.
