Answer

Answer

A study by Mo et al indicated a neuropathic source for burning mouth syndrome, finding a loss of thermal sensitivity in individuals with the condition. In the study, which included 25 patients with burning mouth syndrome and 19 controls, temperature and mechanical detection and pain thresholds were measured on the dorsum of the left hand, the skin over the mental foramen, the tip of the tongue, and the mucosa of the lower lip. Analysis of the cold detection and heat pain thresholds showed significantly less sensitivity to cold and heat on the tongues and lips of the burning mouth syndrome patients when compared with the controls. However, the mechanical detection and pain thresholds did not differ significantly between patients and controls at any of the measurement sites. [12]
