ObjectiveThis study aimed to assess the response to conservative treatment of pain in patients diagnosed with masticatory myofascial pain (MMP) with or without migraine.Study DesignA total of 61 patients were evaluated and divided into 2 groups: Group 1 (G1), patients with MMP (n = 34); Group 2 (G2), patients with MMP and migraine (n = 27). Pain was assessed subjectively by visual analog scale (VAS) and objectively through masticatory muscle palpation at baseline and after 3 treatment visits. Treatment included occlusal appliances, medication, and self-care exercises.ResultsG2 reported greater discomfort subjectively and objectively at all evaluation visits; however, significant difference between groups was noted objectively only at baseline (P = .0052). Regardless of group, pain levels decreased significantly over time as measured by VAS analyses (G1 P = .0033; G2 P = .0031) and muscle palpation (G1 P < .0001; G2 P < .0001).ConclusionsEvidence-based therapy improved pain scores over time in MMP patients regardless of the presence of migraine.Copyright © 2013 Elsevier Inc.
