Abstract
|
|
|
Temporomandibular disorders(TMD) have been defined as a collective term embracing a number of clinical problems that
involve the temporomandibular joint, the masticatory muscles, and associated structures. Since Dr. James Costen has mentioned about the relationship between TMD and posterior bite collapse, there have been many controversies about the etiology and comorbidities of TMD. The purpose of this study was to investigate the relationship between TMD and hearing acuity in 158 volunteers with or without TMD symptoms. The subjects were examined clinically about TMJ sound, missing teeth, tinnitus, TMJ pain and masticatory muscle pain and the hearing acuity were measured by Audiometer(ITO AE-1000, Japan). The result of this study indicated that there was no significant differences between TMD symptoms and hearing acuity relatively.
