ABSTRACT BACKGROUND AND OBJECTIVES: To relate biopsychosocial variables of Research Diagnostic Criteria for Temporomandibular Disorders to groups of patients with temporomandibular disorders, temporomandibular disorders and migraine and a control group. METHODS: This is a cross-sectional observational study where 280 consecutive patients were evaluated and distributed in three groups: group I (140 control individuals); group II (65 individuals with muscle temporomandibular disorders) and group III (75 individuals with migraine and muscle temporomandibular disorders). Exclusion criteria were individuals with clinical history of muscle inflammatory processes, muscle spasms, contractures and acute temporomandibular joint traumatic injury. RESULTS: Group III individuals had association with severe depression (p<0.001), level 4 in pain severity (p=0.004), unspecific physical symptoms without severe pain (p<0.0001) and unspecific symptoms with severe pain (p<0.00001). There has been significant difference between females and males in group III (Z=2.59; p=0.001), with longer pain duration among females. The percentage of females in group III was significantly higher as compared to males (p=0.004). CONCLUSION: The relationship between variables and the three groups has shown a higher number of individuals with more severe symptoms in group III. So, it is understood that migraine is a morbid condition often associated to temporo mandibular disorders, worsening symptoms referred by patients. There is the need for multidisciplinary evaluation of these individuals to optimize treatment and minimize morbidity, costs and the number of medical visits.
