It is estimated that up to 10% of the American public has some form of Temporomandibular Joint Disorder (TMD), of whom perhaps 5% may seek or need treatment. The purpose of this study is to demonstrate that chewing gum for 5 minutes on the involved side at levels less than maximal contraction will decrease resting muscle tone in the masseter muscle as demonstrated through surface electromyography.; This study examined 40 normal subjects as well as 6 people diagnosed with TMD. The results showed that there was a significant decrease in masseter output after the intervention as measured by EMG in the normals. There was not enough data in the TMD population from which to make conclusions.
