Burning mouth syndrome (BMS) is an idiopathic orofacial pain disorder of unclear etiology, now attributed to neuropathic genesis. Since previous approaches to treating BMS have not proven to be more successful than placebo, the study aimed to investigate a special phenomenon of BMS, not accepted or included in any of the existing definitions, that in these patients the burning symptom temporarily reduces/disappears during meals. The study included 52 subjects examined for spontaneous burning pain of the oral cavity with healthy oral mucosa at sites where symptoms were reported. Symptom intensity was recorded using a numerical pain rating scale of 0-10. The beginning of alleviation and withdrawal of symptoms was measured with a stopwatch after the beginning of chewing a piece of paraffin and dissolving a candy in their mouth. After achieving complete (or maximum) improvement, the time until the symptoms returned was measured. All but one subject (98,1%) improved during the experiment, while 44 of them (84,6%) achieved a temporary complete remission by at least one stimulus. The improvement starts within the first minute, while the maximum effect is achieved within three minutes. The return of symptoms after the end of stimulation begins around the first minute and returns to the initial level within three minutes and 20 seconds. In conclusion, this phenomenon provides a quick and accurate diagnosis of BMS simply and reliably, while temporarily managing the symptoms with certainly the highest percentage of effectiveness. For this reason, our results call for its inclusion in the definition of BMS.
