Medical thermography is a noninvasive technique that allows an examiner to visualize and estimate the temperature of the body . This technique allows for an evaluation of the functionality of the structures, which is why it is considered a physiological test and records the variation in the surface temperature of the human body based on the infrared radiation emitted by the surface of that body .Subjects with burning mouth syndrome (BMS) have altered sensitivity and pain thresholds for thermal stimuli compared to a control group An objective of this study is to standardize temperature values derived from thermograms of the tongue in BMS .

Subjects will make one visit to our clinic with burning mouth syndrome and control healthy . They will be asked to acclimate to room temperature for at least 20 minutes. Subjects are requested not to consume hot drinks or food for at least an hour before imaging and not to use any skin preparations. During the tests, infrared thermal images were taken immediately after subjects protruded their tongues forward and downward to the desired position
