Sensory and Pain Thresholds to Orofacial Argon Laser Stimulation in Patients with Chronic Burning Mouth Syndrome

Abstract

The presence of abnormal prepain perceptions and disturbances in the perception of nonnociceptive and nociceptive thermal stimuli applied on both pain-affected and normal regions suggest a perceptual deficit unrelated to specific pathophysiological mechanisms in BMS. However, it appears that a psychological explanation of BMS should be used cautiously, as the present results suggest alterations in sensory function.
