• Lead Sponsor: Istanbul University

Brief Summary

The term temporomandibular joint disorder (TMD) refers to a group of disorders affecting the temporomandibular joint and/or muscles of mastication. Typical symptoms are; joint noises, pain, and limited mouth opening. Many therapeutic modalities have been advocated for the treatment of TMD as intraoral splints, laser, ultrasound, physical therapy, surgery, and medications with inconsistent reported results due to the multifactorial etiology of this disorder. Although intraoral splints are the most widely used therapy, it has some drawbacks as being inconvenient for the patient due to their relatively large size interferes with eating and affects speech, therefore their use is mostly limited to sleeping time, which decreases its effectiveness.

Recently some commercial earplugs that claim to treat TMD have been introduced, however, there is no validated data regarding these appliances. Thus, this study aimss to evaluate the possible effect of earplugs on myogenous TMD.
