Diagnosing Headache and Facial Pain
One of the first manuscripts that purported to identify the cause of TMD was published by Coston in 1934 . The loss of hearing, tinnitus, dizziness, headache, and a burning sensation of the throat and tongue were then thought to be the result of a dental malocclusion. The association between malocclusion and TMD remains very controversial for many reasons including the high prevalence of malocclusion in the general population . At the present time, there is little evidence to support occlusion as a predisposing factor, nor is there any evidence to support occlusal equilibration, prosthodontics, and orthodontics in the prevention and treatment of TMD [6, 7]. Likewise occlusal interferences are not thought to result in the development of TMD and the treatment of interference is unlikely to result in resolution of TMD [6-11]. The etiology of TMD is clearly complex, and making the correct diagnosis in the face of so many potential sources of facial pain can be challenging .
