Conditioned pain modulation is associated with anesthesia efficacy in patients with temporomandibular disorder.
Abstract Conditioned pain modulation (CPM) assesses descending pain inhibition in humans and has been shown to be clinically relevant. However, the possible contribution of the CPM response to the efficacy of local anesthetics remains poorly understood. This study aimed to evaluate the association between the CPM response and the efficacy of topical anesthesia applied to the trigeminal region in females with chronic orofacial pain and healthy participants. Thirty-five females with painful tempo...
