Temporomandibular disorders and chronic daily headaches in the community and in specialty care.

BACKGROUND: Chronic daily headaches (CDHs) are often associated with temporomandibular disorders (TMDs). However, large studies assessing the relationship were conducted in general, and not clinical, populations. Thus, clinical exams were not completed. Clinic-based studies with expert diagnosis are, in turn, often small and may not be representative. OBJECTIVE: To contrast the demographic and clinical symptoms of CDH and TMD in participants within the general population relative to patients seen in a headache clinic. METHODS: All inhabitants 10 years and older of a small city in Brazil were interviewed. Those with more than 15 days of headache per month were examined by a team consisting of a neurologist, a dentist, and a physical therapist. Headaches were classified as per the Second Edition of the International Classification of Headache Disorders and TMD as per the Research Diagnostic Criteria. The procedure was repeated (by the same team) with CDH sufferers consecutively seen in a headache center. RESULTS: Of 1605 inhabitants interviewed, 57 (3.6%) had CDH, and 43 completed all physical assessments. For specialty care group, of 289 patients, 92 had CDH, and 85 completed all assessments. No significant differences were seen for gender and age, but education level was significantly higher among those recruited at specialty care. Muscular TMD happened in 30.2% of CDH patients from the community vs 55.3% in the headache center (difference of -25.1%, 95% confidence interval of difference=-40.8% to -9.4%). No TMD happened in 41.9% of those recruited from the population relative to 20% of those in the headache center (21.9%, 95% confidence interval=6.7-37.1%). CONCLUSION: Individuals with CDH recruited from the general population are significantly less likely to have CDH relative to those selected from the headache center. Issues of generalizability are of concern when conducting clinic-based studies on the topic.

Combined palliative and anti-inflammatory medications as treatment of temporomandibular joint disc displacement without reduction: a systematic review.

The aim of this study was to evaluate the efficacy of self-care combined with anti-inflammatory medications in the treatment of temporomandibular joint (TMJ) pain associated with disc displacement without reduction (DDWOR). A systematic review of randomized clinical trials was done by the authors. The databases searched were Medline (1966 to July 2012); EMBASE (1980 to July 2012); and LILACS (from 1982 to July 2012). The review authors independently assessed trials for eligibility and methodological quality and also extracted all data. The data was double-checked for accuracy. There was no language restriction in the searches of EMBASE, PubMed, and LILACS databases, or in the manual search. The risk of bias and the heterogeneity of the studies taken into consideration were assessed. Two studies, randomizing 175 patients, were included in this review. The first study (n = 106) compared the following interventions: medical treatment, rehabilitation, arthroscopic surgery with postoperative rehabilitation, or arthroplastic surgery with post-operative rehabilitation. The second study (n = 69) compared the use of nonsteroidal anti-inflammatory medications and self-care instructions, nonsteroidal anti-inflammatory medications, occlusal splint, and mobilization therapy. The third group received no treatment; patients were only informed of their prognosis. There is no sufficient evidence regarding efficacy and safety of the palliative treatments associated with anti-inflammatory versus other treatments, or absence of treatment on pain reduction in patients with TMJ DDWOR.

Temporo-mandibular disorders are an important comorbidity of migraine and may be clinically difficult to distinguish them from tension-type headache.

UNLABELLED: Clinical differentiation between the primary headaches and temporomandibular disorders (TMD) can be challenging. OBJECTIVES: To investigate the relationship between TMD and primary headaches by conducting face to face assessments in patients from an orofacial pain clinic and a headache tertiary center. METHOD: Sample consists of 289 individuals consecutively identified at a headache center and 78 individuals seen in an orofacial pain clinic because of symptoms suggestive of TMD. RESULTS: Migraine was diagnosed in 79.8% of headache sufferers, in headache tertiary center, and 25.6% of those in orofacial pain clinic (p<0.001). Tension-type headache was present in 20.4% and 46.1%, while the TMD painful occurred in 48.1% and 70.5% respectively (p<0.001). CONCLUSION: TMD is an important comorbidity of migraine and difficult to distinguish clinically from tension-type headache, and this headache was more frequent in the dental center than at the medical center.

A diferenciação clínica entre as cefaleias primárias e as disfunções temporomandibulares (DTM) pode ser desafiadora. Objetivos : Investigar a relação entre DTM e cefaleias primárias conduzindo uma avaliação face a face entre pacientes de um centro de dor orofacial e de um centro terciário de cefaleia. Método : A amostra consistiu de 289 indivíduos avaliados consecutivamente em um centro terciário de cefaleia e 78 indivíduos de uma clínica orofacial. Resultados : A migrânea foi diagnosticada em 79,8% dos pacientes do centro de cefaleia e 25,6% dos pacientes do centro de dor orofacial. A cefaleia do tipo tensional esteve presente em 20,4% e 46,1%, enquanto as DTM dolorosas ocorreram em 48,1% e 70,5% respectivamente (p<0,001). Conclusão : DTM é uma comorbidade importante da migrânea e difícil de distinguir clinicamente da cefaleia do tipo tensional, tanto que esta cefaleia foi mais frequente no centro odontológico do que no centro médico. .

Occlusion and temporomandibular disorders: a critical analysis of the literature / Oclusão e disfunção temporomandibular: uma análise crítica da literatura

BACKGROUND AND OBJECTIVES: Occlusion has been considered an important risk factor for the temporomandibular disorders (TMD). To check the pertinent literature in a systematic way and proceed to a critical analysis to elucidate the relation of the occlusal factors with temporomandibular disorders and to establish a consensus to standardize and define behaviors in clinical practice as well as select effective/safety treatments for the patient.CONTENTS: The therapeutic modalities that change the occlusal surface, teeth position and the mandibular position will be discussed to establish parameters that can assess the real importance of these factors in the etiology of the TMD. The following databases were researched: PubMed (1966-2008), Lilacs (1982-2008). Manual search was also carried out. The search strategy was realized according to each database. The selected articles were submitted to a critical analysis.CONCLUSION: The failure to obtain of an ideal/functional occlusion won?t necessarily results in signals and symptoms of TMD. The occlusal adjustment wouldn't be indicated to treat TMD; it does not present adequately effectiveness and safety. Orthodontic treatment wouldn't be recommended to prevent or treat TMD. The stabilization splint of nocturnal use shows evidence/effective and safe intervention to the control of the masticatory myofascial pain.

JUSTIFICATIVA E OBJETIVOS: A oclusão tem sido considerada importante fator de risco de disfunção temporomandibular (DTM). O objetivo foi revisar a literatura de forma sistemática e proceder à análise crítica para elucidar a relação dos fatores oclusais com DTM, e criar consenso para a prática clínica.CONTEÚDO: Este estudo discute modalidades de tratamento que modificam a superfície oclusal, a posição dentária e a posição mandibular para se estabelecer parâmetros que avaliem o real papel desses fatores na etiologia da DTM. É apresentado um consenso, baseado em evidência, para padronizar/definir condutas na prática clínica e selecionar tratamentos eficazes e seguros para o paciente. Foram pesquisadas as bases de dados: Pubmed (1966-2007) e LILACS (1982-2007). Foi realizada busca manual em revistas e referências de artigos incluídos. A estratégia de busca foi adaptada a cada base de dados.CONCLUSÃO: A não obtenção de uma oclusão ideal/funcional não resulta necessariamente em sinais/sintomas de DTM. O ajuste oclusal não deve ser indicado para tratar DTM, por não apresentar efetividade e segurança adequados. O tratamento ortodôntico não deve ser recomendado para prevenir ou tratar DTM. A placa estabilizadora de uso noturno apresenta evidência como intervenção segura e efetiva para o controle da dor miofascial mastigatória.
