RELATION BETWEEN TEMPOROMANDIBULAR DISORDERS AND HEADACHES:BIBLIOGRAPHIC REVIEW
Keywords:
temporomandibular joint dysfunction syndrome, temporomandibular joint, headache, tension-type headache.Abstract
Introduction: the incidence of temporomandibular disorders (TMD) is up to 50 % in the adult population and headache can be extremely disabling in severe cases. In addition, both pathologies can appear simultaneously. Therefore, it is necessary to know the scientific evidence on the relationship of both pathologies in the adult population.
Objective: the aim of this study is to review the scientific evidence regarding the relationship between temporo-mandibular disorders and headaches among the adult population. Material and method: a search for observational articles in English and Spanish was performed in the Medline Complete, Cinhal Complete and Academic Search Complete databases. Articles that analyzed in adults the relationship between TMD and headaches in adults from different variables were included. A critical reading of each article was made through the Newcastle-Ottawa Quality Assessment Scale. Results: eight articles met the eligibility criteria and were part of the present review. Six of them assessed how the presence of temporomandibular disorder could influence headaches, while 3 studies studied headache as a risk factor to verify its relationship with temporomandibular disorders. All studies fulfill STROBE criteria for observational studies. Conclusion: there is a relationship between TMD and headaches, both pathologies appearing simultaneously, despite the need for a muscular component in TMD to produce a headache. The greater the pain or the severity of the TMD, the more likely you are to have a headache. Migraine is the type of headache most closely related to TMDs.
