BITE PROBLEMS ASSOCIATED WITH HEADACHES ACCORDING TO NEW ARTICLE IN THE JOURNAL OF PROSTHETIC DENTISTRY, JUNE 2011

THE PRIMARY INDICATION THAT THE TEETH, BITE AND TEMPOROMANDIBULAR APPARATUS are involved in headaches and migraines is the involvement ot the Trigeminal nerve in all of these disorders. The input to the trigeminal nerve can cause nociceptive nervous input which results in headaches, migraines and other autonomic and somatic symptoms.

Neuromuscular Dentistry reduces the nociceptive input into the central nervous system and can often eliminate or prevent many types of headaches and migraines, especially those involving trigeminally innervated tissues including teeth, jaw muscles, jaw (TMJ)joints, eustacian tubes, muscles that tighten the eardrum. This can correct blood flow to the anterior 2/3 of the meninges to the brain.

Abstract
STATEMENT OF PROBLEM: Although an interaction of malocclusion, parafunction, and temporomandibular joint disorders (TMD) can be inferred from the experience of daily practice, scientific evidence to corroborate this hypothesis does not exist. However, there are indications that TMD and headaches may be intertwined.

PURPOSE: The purpose of this study was to identify the presence or absence of an association of occlusal interferences, parafunction, TMD, or physiologic, muscular, or prosthodontic factors with the occurrence of headache.

MATERIAL AND METHODS: In a private practice population of 1031 subjects (436 men and 595 women, mean age 49.6 years) the demographic parameters, headache and general pain history, habits and general personal information were recorded. Clinical examination for dental, muscular, and temporomandibular joint pathology was accomplished. Data were statistically analyzed using the Mann-Whitney U, Kruskal-Wallis, and Chi-Square tests (α = .05). A multinomial logistic regression analysis was performed with respect to confounding variables.

RESULTS: Headache affliction was found to affect women more frequently than men (1.7:1). Students and non academics were more prone to suffer from headache. Parafunction (P=.001), TMD (P=.001) and gross differences between centric occlusion and maximum intercuspation of more than a 3 mm visible track marked with 8 μm articulation foil (P=.001) significantly influenced the presence of headache. Headache intensity and frequency decreased with age. While tension-type headache was most frequently diagnosed, the parameters studied were not significantly associated with one certain headache diagnosis more frequently than others.

CONCLUSIONS: Stomatognathic factors of TMD, parafunction, and gross differences between centric occlusion and maximum intercuspation of more than 3 mm are associated with headache. These findings should be interpreted with caution due to the cross-sectional nature of this study.
