Summary
Temporomandibular disorders (TMD) are linked to specific headache types like migraine and chronic daily headaches. TMD severity and subtypes, particularly muscular pain, significantly increase headache frequency and risk.
Area of Science:
- Neurology
- Pain Medicine
- Dental Medicine
Background:
- Temporomandibular disorders (TMDs) are frequently comorbid with headaches.
- Previous research suggests TMD may influence migraine progression.
Purpose of the Study:
- To investigate the association between TMD subtypes and severity with primary headache syndromes.
- To differentiate TMD's impact on specific headaches versus general headaches.
Main Methods:
- A controlled clinical study involving 300 individuals.
- TMD assessment using the Research Diagnostic Criteria for TMD.
- Primary headache classification via the International Classification for Headache Disorders-2.
Main Results:
- Individuals with myofascial TMD showed higher likelihood of chronic daily headaches (CDH), migraine, and episodic tension-type headache.
- TMD pain grade and severity correlated with increased odds of CDH, migraine, and headache frequency.
- Multivariate analyses confirmed TMD association with migraine and CDH, with painful TMD and pain grade linked to headache frequency.
Conclusions:
- TMD, its subtypes, and severity are independently associated with specific headache syndromes and frequency.
- The association is particularly noted with muscular TMD pain, suggesting central facilitation mechanisms.
