Temporomandibular Joint Disorder Associated With Migraine – Clinical Study

Abstract

<i>Objectives:</i> The aim of this study was to assess the prevalence of Temporomandibular Disorders (TMD), using the Research Diagnostic Criteria for TMD (RDC/TMD) in women with episodic and chronic migraine (M and CM), as well as in asymptomatic women. Method: Sample consisted of 100 women, being 40 with M and 27 with CM, identified from a headache outpatient center; we also investigated 33 women without headaches for at least 3 months (women without headache group — WHG). Assessment of TMD was conducted by a physical therapist who was blind to the headache status. Results: Our sample consisted of 100 women. The mean age was 37.18 years for WHG, 38.16 years for M and 37.83 for CM. TMD was diagnosed in 10 women from the WHG, 33 women with M group and 21 women with CM group. TMD was significantly more prevalent in women with M and CM groups, as compared to WHG (Table 1). As compared with women without headache, women with M and CM were significantly more diagnosed with TMD and also presented higher risk for TMD (Table 1). <i>Diagnoses</i> of group I were the most prevalent in all groups. Mixed diagnoses (I+II and I+II+III) were observed only in individuals with migraine, and were more common in CM than in M group. Diagnoses of groups I+III were observed in the three groups, but were more prevalent in the M group than in the other groups. TMDs from groups II and III were not observed. Conclusion: Women with migraine are more likely to have muscular and articular TMD, suggesting that both disorders might be clinically associated, which demonstrate the importance of physical therapy assessment in the multidisciplinary team.
