Electromyographic indices, orofacial myofunctional status and temporomandibular disorders severity: A correlation study.

摘要: Abstract This study examined whether there is an association between surface electromyography (EMG) of masticatory muscles, orofacial myofunction status and temporomandibular disorder (TMD) severity scores. Forty-two women with TMD (mean 30years, SD 8) 18 healthy 26years, 6) were examined. According to the Research Diagnostic Criteria for (RDC/TMD), all patients had myogenous disorders plus disk displacements reduction. Surface EMG masseter temporal muscles was performed during maximum teeth clenching either on cotton rolls or in intercuspal position. Standardized indices obtained. Validated protocols used determine perception assess myofunctional status. showed more asymmetry right left muscle pairs, unbalanced contractile activities contralateral ( p t -test), worse higher scores In conclusion, these methods will provide useful information diagnosis future therapeutic planning.
