Abstract

Objective: To identify temporomandibular disorders (TMD) symptoms in two groups of fibromyalgia patients according to the temporal relation between the onset of facial pain (FP) and generalized body pain (GBP). Cross-sectional study design: Fifty-three consecutive women with fibromyalgia and FP were stratified according to the onset of orofacial pain: Group-A (mean age 47.30 ± 14.20 years old), onset of FP preceded GBP; Group-B (mean age 51.33 ± 11.03 years old), the FP started concomitant or after GBP. Clinical assessment: Research Diagnostic Criteria for Temporomandibular Disorders and the Visual Analogue Scale. Results: Myofascial pain with mouth opening limitation (p = 0.038); right disc displacement with reduction (p = 0.012) and jaw stiffness (p = 0.004) were predominant in Group A. Myofascial pain without mouth opening limitation (p = 0.038) and numbness/burning were more common in Group B. Conclusion: All patients had temporomandibular joint symptoms, mainly muscle disorders. The prevalence of myofascial pain with limited mouth opening and right TMJ disc displacement with reduction were higher in Group A.
