Comparative analysis between electromyographic findings of masseter muscle in patients with and without temporomandibular disorder: part I
Journal Title: RSBO - Year 2009, Vol 6, Issue 4
Abstract
Introduction: The need to understand the changes of the masseter muscle in the temporomandibular disorders has been leading more often the dental surgeon to work together with other health professionals, with a multidisciplinary focus, which seems to be the best condition to help patients with such complex disorder. Objective: To evaluate the possible modifications of the masseter muscle regarding the muscle tension value (RMS) in patients with and without temporomandibular joint disorder (TMD) through electromyography.Material and methods: 20 volunteers were selected (11 without TMD and 9 with TMD), with full dentition and Angle class I occlusion.Results:Statistically significant difference was found in the values of the electromyographic data regarding muscle tension at rest and during maximum intercuspidation in the right and left sides of the masseter muscle for both groups. Besides, the obtained values of the muscle tension through electromyography follow a mathematical standard that allowed the creation of a linear regression equation: EMG-MIC = 528.75 – (54.76 x EMG-REP). Conclusion: Data obtained through electromyography were effective to prove the physiological changes in the masseter muscle in the group with TMD in comparison to the group without TMD.
