The objective of this study was to investigate the sensorial characteristics of orofacial pain in patients compared with control subjects. A total of 336 subjects (282 patients and 54 control subjects) were evaluated to identify their thermal (cold and warm), tactile, and pain thresholds. Numbness was reported by 61.7% of the patients (p<0.001). Patients with trigeminal postherpetic neuralgia and burning mouth syndrome showed loss of thermal perception; patients with postherpetic neuralgia, burning mouth syndrome, and posttraumatic painful neuropathy had a decrease in tactile perception compared with the control subjects (p<0.001). In conclusion, other sensorial modalities besides pain are affected by neuropathic orofacial pain; these findings can help in the understanding of the pathophysiological mechanisms in orofacial pain. |
