RESUMO
OBJECTIVE: A systematic review was performed to synthesize and identify risk factors involved in TMD onset. STUDY DESIGN: Electronic searches were conducted in PubMed, Web of Science, Scopus, Embase, PsyInfo and Lilacs databases, as well as in three gray literature databases (Google Scholar, ProQuest and Open grey). The studies were blindly assessed by two reviewers and selected by a pre-defined eligibility criterion. Risk of bias of included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Cohort Studies. Grading of Recommendations Assessment, Development and Evaluation (GRADE) was evaluated for most related factors. RESULTS: Twenty-one cohort studies were included. Significant factors were female gender, symptoms of depression and anxiety, perceived stress, sleep quality, symptoms of obstructive sleep apnea and presence of any comorbidity, such as Irritable Bowel Syndrome, lower back pain, headache frequency, tension-type headache, migraine and mixed headache. Moreover, high estrogen and low testosterone levels in utero, greater pain perception, jaw mobility pain, pain during palpation, orofacial anomalies, as well as extrinsic and intrinsic injuries were also significant. CONCLUSIONS: Several factors seems to be involved in TMD onset, however, more studies with standardized methodology are necessary to confirm these findings.
RESUMO
OBJECTIVES: To evaluate the prevalence of awake bruxism (AB) in the adult population. MATERIALS AND METHODS: Six main electronic databases and three sources of grey literature were searched to identify cross-sectional studies in which AB was assessed. The studies were independently selected by two reviewers in two phases, based on their eligibility criteria. The first one consisted of reading titles and abstracts, and the second one involved reading the full articles. The study quality assessment was obtained by using the "Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data", and the "R Statistics" software was used to perform meta-analyses. RESULTS: Seventeen out of 3086 identified studies were included. None of the studies scored high in methodological quality across all 9 items of the JBI checklist. However, "the use of valid methods to identify pathology" and "appropriate statistical analysis" were considered to have high methodological quality in all the studies. The overall pooled prevalence of the meta-analysis was 15.44% (99% confidence interval: 10.81 to 20.72%) and there was no difference for sex, sampling method and according to consensus-based classification. CONCLUSIONS: The prevalence of AB in adults was low. There was substantial methodological variability, which highlights the need for standardized guidelines. CLINICAL RELEVANCE: Prevalence data are useful for raising patients' and clinicians' awareness of the AB. Moreover, since AB can lead to possible pain and overload of the stomatognathic system, this knowledge can also guide dentists to achieve an early diagnosis of AB and to provide appropriate care management.

OBJECTIVE: To determine the best disocclusion guidance in occlusal splints (OSs) to manage and treat temporomandibular disorder (TMD) and sleep bruxism (SB). STUDY DESIGN: The research was conducted on 7 major electronic databases and 3 gray literature sources. We included randomized trials, nonrandomized clinical trials, and before-and-after studies. The risk of bias (RoB) was assessed by Joanna Briggs Institute of Critical Appraisal Tools. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to grade the certainty of evidence. RESULTS: Qualitative synthesis included 16 surveys reporting data from 620 participants. Canine guidance (CG) was widely searched. Bilateral balanced occlusion (BBO) and CG significantly decreased pain levels compared with the placebo splint. Comparing between OS and absence of therapy, only CG was assessed and showed significant improvements on mouth opening, pain, sleep quality, and muscle activity. When compared different guide types among themselves, no significant improvement was founded in any evaluated outcome. Three studies presented high RoB, 7 presented moderate RoB, and 6 presented low RoB. CONCLUSIONS: It is suggested there is not enough evidence to support that there are any specific kind of guidance responsible for improving evaluated outcomes on TMD and SB.

Viscosupplementation (VS) of the temporomandibular joint (TMJ) aims to treat temporomandibular dysfunction (TMD) by stimulating synovial cells to improve intracapsular lubrication. The purpose of the present study was to assess a VS protocol planned with the aid of cone-beam computed tomography (CBCT) and checked by ultrasonography (US). The study was carried out in 3 stages. The first was to check the correspondence between the proposed facial reference points and the osseous components of the joint by means of CBCT. In the second stage, the upper and lower compartments of 20 TMJs of fresh frozen cadavers were injected with coloured liquids, and the accuracy of the technique was confirmed by dissecting the anatomical specimens. The third stage consisted of VS in 10 patients (20 TMJs), with real-time verification of the location of the needle tip by means of ultrasonography. CBCT confirmed the correct locations of the marked points used in the proposed VS protocol. The dissections showed that 13 of the 14 injections effectively reached the upper and lower compartments. The location of the needle tip was effectively verified by ultrasonography, confirming the correct access to both compartments. The proposed protocol was effective for accessing the upper and lower compartments of the TMJ. The evaluated protocol proved to be accurate, safe and clinically reproducible means of VS in the upper and lower compartments of the TMJ.

The use of botulinum neurotoxin-A (BoNT-A) is an alternative for the management of orofacial pain disorders. Although only Botox has labeled, there are other commercial brands available for use, among them: Dysport, Botulift, Prosigne, and Xeomin. The objective of the present study was to evaluate the possible differences in the antinociceptive effect evoked by different commercially available formulations of BoNT-A in an animal model of inflammatory orofacial pain induced by formalin injection. Male C57/BL6 mice (20-25 g) were submitted to the pre-treatment with five different commercial brands of BoNT-A (Botox, Botulift, Xeomin, Dysport, or Prosigne; with doses between 0.02 and 0.2 Units of Botulinum Toxin, in 20 µL of 0.9% saline) three days prior the 2% formalin injection. All injections were made subcutaneously into the right perinasal area. After formalin injections, nociceptive behaviors like rubbing the place of injection were quantified during the neurogenic (0-5 min) and inflammatory (15-30 min) phases. The treatment using Botox, Botulift, and Xeomin were able to induce antinociceptive effects in both phases of the formalin-induced pain animal model, however, Dysport and Prosigne reduced the response in neither of them. Our data suggest that the treatment using different formulations of BoNT-A is not similar in efficacy as analgesics when evaluated in formalin-induced orofacial pain in mice.
RESUMO
OBJECTIVES: The aim of this systematic review was to evaluate the prevalence of temporomandibular joint disorders (TMJD) among the general population. MATERIALS AND METHODS: Five main electronic databases and three grey literature were searched to identify observational studies in which TMJD was diagnosed using the research diagnostic criteria (RDC/TMD) or diagnostic criteria (DC/TMD). The studies were blindly selected by two reviewers based on eligibility criteria. Risk of bias (RoB) was assessed using the Joanna Briggs Institute Critical Appraisal Checklist, and the "R" Statistics software was used to perform meta-analyses. RESULTS: From 2741 articles, 21 were included. Ten studies were judged at low RoB, seven at moderate, and four at high. The TMJD investigated were as follows: arthralgia, disk displacement (DDs) with reduction (DDwR), DDwR with intermittent locking, DDs without reduction (DDwoR) with limited opening, DDwoR without limited opening, degenerative joint disease (DJD), osteoarthritis, osteoarthrosis, and subluxation. The main results from prevalence overall meta-analyses for adults/elderly are as follows: TMJD (31.1%), DDs (19.1%), and DJD (9.8%). Furthermore, for children/adolescents are as follows: TMJD (11.3%), DDs (8.3%), and DJD (0.4%). Considering the individual diagnosis meta-analyses, the most prevalent TMJD is DDwR for adults/elderly (25.9%) and children/adolescents (7.4%). CONCLUSIONS: The overall prevalence of TMJD was approximately 31% for adults/elderly and 11% for children/adolescents, and the most prevalent TMJD was DDwR. CLINICAL RELEVANCE: Knowledge about the frequency of TMJD can encourage dentists to consider appropriate strategies for early and correct diagnosis and, if need be, correct management.

SARS-COV-2 is a highly pathogenic coronavirus that causes the disease known as COVID-19, which has infected more than 100 million people worldwide. The main form of containment of the pandemic is social isolation. However the isolation, the severity of the COVID-19 disease, the uncertainty of the future and the economic impact are the possible causes of anxiety as an adverse effect of the pandemic. The literature describes the possible association between anxiety with poor sleep quality, exacerbation of painful conditions, gastroesophageal reflux disease, increased consumption of drugs and the possibility of developing or enhancing sleep bruxism. Health professionals should keep in mind the possibility of overlapping with the different clinical conditions mentioned and the need for a multi-professional team to manage these patients.
RESUMO
Exacerbation of nighttime sleep-related oromotor activity is often recognized as a relevant clinical entity commonly known as sleep bruxism (SB). Many pragmatic issues about SB diagnosis and management remain controversial. Therefore, within a critical review of the literature, this article proposes an operational clinical approach for SB diagnosis and management, with a focus on three comorbidities frequently occurring in relation to sleep: obstructive sleep apnea (OSA), gastroesophageal reflux disease (GERD), and insomnia. In the absence of any comorbidities, and if clinically justified, short-term medication and/or splints may be considered. If a comorbid condition is suspected, then the patient should be screened for OSA, GERD, and insomnia. For OSA screening, the Epworth Sleepiness Scale, STOP-Bang, and NoSAS questionnaires are available validated tools. For GERD screening, a positive patient report, whether associated or not with clinical signs and symptoms of heartburn and/or regurgitation, can be tested. For insomnia screening, report of difficulties initiating or maintaining sleep or of early morning awakening more than three times a week may be useful for diagnosis clarification. An adequate clinical approach for comorbid SB requires that both SB and the related comorbid condition be properly assessed and managed. Very often, improvement of SB with treatment of the associated condition will confirm the relationship and establish a more precise diagnosis (ie, secondary SB). Clinicians intending to manage SB should be able to identify these possible clinical interactions, and, if needed, perform an integrative multidimensional approach. Some approaches will benefit from a multidisciplinary approach for achieving therapeutic success.

Viscosupplementation is a minimally invasive technique that replaces synovial fluid by intra-articular injection of hyaluronic acid (HA). Although effective in some joints, there is not conclusive evidence regarding temporomandibular disorders. This case series described the efficacy of a viscosupplementation protocol in intra-articular temporomandibular disorders. Ten patients with a diagnosis of disc displacement and/or osteoarthritis by Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were submitted to four monthly injections of low or medium molecular weight HA. Pain, mandibular function, image analysis by tomography and magnetic resonance, and quality of life were assessed at baseline and follow-ups (1 and 6 months). Pain, jaw range-of-motion, mandibular function, and quality of life improved at follow-up evaluations. Osteoarthritis changes decreased, and 20% of patients improved mandibular head excursion after treatment. Resolution of effusion and improvement in disc morphology were observed for most patients. This viscosupplementation protocol reduced pain and symptoms associated with internal derangement of temporomandibular joint, improved quality of life, and showed benefits from both low and medium molecular weight HA in alternate cycles.

ABSTRACT BACKGROUND AND OBJECTIVES: Temporomandibular disorders are diseases causing pain and dysfunction in joints and muscles controlling mandibular movements. Their etiology is multifactorial and multidisciplinary approaches are needed to reach a differential diagnosis and an adequate management plan. This case report proposes a management protocol, with monthly sodium hyaluronate infiltrations, with different molecular weights, to control such changes and promote improvement of temporomandibular joint biomechanics and pain. CASE REPORT: This study describes a case of a 48-year old patient with a 10-year history of temporomandibular pain with function loss since 2001. Patient has classified her pain as 9 according to analog visual scale. In addition, history and detailed physical evaluation have shown different signs and symptoms, such as localized pain (right side), and right temporomandibular joint arthralgia with noise. Diagnosis was disc displacement with reduction and possible synovitis/ capsulitis to the right. Right temporomandibular joint osteoarthritis was also diagnosed by cone beam CT-scan. Initially, a flat upper splint with total coverage and contact with all antagonist teeth was used. In the attempt to decrease temporomandibular arthralgia, non-steroid anti-inflammatory drugs and muscle relaxants were used. Since right temporomandibular joint pain was not effectively managed, we decided to use intra-joint sodium hyaluronate injections with different molecular weights, per month, in a total of four applications. At treatment completion, clinical evaluation has shown normal function, no pain with visual analog scale = zero, in addition to adequate interincisal distance. CONCLUSION: This report has suggested that viscosupplementation cycles with sodium hyaluronate of different molecular weights may provide excellent results in the long run, to control joint temporomandibular disorder symptoms. Therapeutic benefits were maintained for four years with no need for annual maintenance cycles.
RESUMO JUSTIFICATIVA E OBJETIVOS: As disfunções temporomandibulares são um grupo de doenças que causam dor e disfunção na articulação e nos músculos que controlam os movimentos da mandíbula. Sua etiologia é multifatorial e abordagens multidisciplinares são necessárias para chegar a um diagnóstico diferencial e plano de tratamento adequado. Propõe-se um protocolo de tratamento, com infiltrações mensais, empregando hialuronato de sódio, com diferentes pesos moleculares, para controlar essas alterações e promover uma melhoria da função biomecânica da articulação temporomandibular, bem como da sua dor. RELATO DO CASO: Este estudo descreve um caso de uma paciente de 48 anos que apresentava uma história de 10 anos de dor temporomandibular com perda de função que apareceu em 2001. Ela classificou a intensidade da sua dor como grau 9 de acordo com a escala visual analógica. Além disso, anamnese e exame clínico detalhado mostraram diversos sinais e sintomas, como dor localizada miofascial (lado direito), artralgia da articulação temporomandibular direita com ruído. O diagnóstico foi de deslocamento de disco com redução e possível sinovite/capsulite à direita. Osteoartrose da articulação temporomandibular direita também foi confirmada por tomografia computadorizada de feixe cônico. Inicialmente, foi utilizada uma placa superior plana de cobertura total com contato com todos os dentes antagonistas. Numa tentativa de diminuir a artralgia temporomandibular, foram empregados anti-inflamatórios não esteroides e um relaxante muscular. Como a dor da articulação temporomandibular direita não foi efetivamente eliminada,optou-se pela utilização de uma injeção intra-articular de hialuronato de sódio, com diferentes pesos moleculares, por mês, totalizando quatro aplicações. No final do tratamento, o exame clínico mostrou normalização da função, a dor havia desaparecido, escala analógica visual=zero, além de uma distância interincisal adequada. CONCLUSÃO: O presente trabalho sugeriu que ciclos de viscossuplementação com hialuronato de sódio, de diferentes pesos moleculares, podem proporcionar excelentes resultados, em longo prazo, no controle de sinais e sintomas da disfunção temporomandibular de origem articular. Os benefícios terapêuticos foram mantidos por um período de quatro anos, sem a necessidade de ciclos anuais de manutenção.
RESUMO
Ear acupuncture works by reducing painful sensations with analgesic effect through microsystem therapy and has been demonstrated to be as effective as conventional therapies in the control of facial pain. This clinical trial aimed to evaluate the adjuvant action of auricular acupuncture through an observation of the evolution of temporomandibular and masticatory myofascial symptoms in two groups defined by the therapies elected: auricular acupuncture associated with occlusal splint (study) and the use of the occlusal splint plate alone (control). We have selected 20 patients, who were randomly allocated into two groups of ten individuals. Symptoms were evaluated in five different moments, every seven days. We analyzed the orofacial muscle and joint palpation in order to measure the intensity of the experienced pain. Both groups showed a statistically significant decrease in muscle and joint symptoms (p < 0.05). However, comparisons between the groups showed an expressive and significant reduction of symptomatology in the study group (p < 0.05) already on the first week of therapy. According to the results, to the methodological criteria developed and statistical analysis applied, the conclusion is that auricular acupuncture therapy has synergistic action on conventional occlusal splint treatment. It was demonstrated to be effective in the reduction of symptoms in the short term.
RESUMO
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.

JUSTIFICATIVA E OBJETIVOS: A disfunção temporomandibular compreende um termo coletivo que envolve alterações clínicas nos músculos da mastigação, das articulações temporomandibulares e/ou estruturas associadas.O objetivo deste estudo foi realizar uma análise crítica, utilizando as principais bases de dados, sobre a efetividade e a segurança do hialuronato de sódio no tratamento das disfunções temporomandibulares de origem articular, a fim de recomendar ou refutar seu uso na prática clínica. CONTEÚDO: Os estudos foram obtidos através das seguintes bases de dados: Medline, via PubMed (1966 - 2013), Registro de Ensaios Controlados Cochrane, (2012), Embase (1980 - 2013) e LILACS (1982 - 2013). A estratégia utilizada foi a busca ajustada para cada base, a fim de identificar o maior número possível de estudos envolvendo o uso do hialuronato de sódio no tratamento da disfunção temporomandibular de origem articular. Houve limitação do idioma, buscando artigos em língua inglesa. Cruzaram-se os seguintes descritores: tratamento da articulação temporomandibular versus hialuronato de sódio versus deslocamento agudo e crônico do disco com e sem redução versus ácido hialurônico versus osteoartrite e osteoartrose versus viscossuplementação. Como critérios de inclusão foram analisados estudos randomizados, uni ou duplamente encobertos, série de casos, com 15 ou mais participantes. Excluíram-se relato de caso, estudos abertos "open-label", estudos em modelos animais e artigos relacionados a tratamento da disfunção artrogênica que não possuíssem como uma das terapias a infiltração de hialuronato de sódio na articulação temporomandibular. A qualidade metodológica desses estudos foi avaliada e classificada conforme o nível de evidência do Oxford Centre for Evidence Based Medicine. CONCLUSÃO: De acordo com a análise crítica dos estudos incluídos, pode-se afirmar que o uso do hialuronato de sódio é eficaz e seguro, sendo recomendado no tratamento das seguintes condições: deslocamento agudo e crônico do disco com redução e sem redução, osteoartrose, osteoartrite e doença articular degenerativa.
BACKGROUND AND OBJECTIVES: Temporomandibular disorder is a collective term involving clinical masticatory muscles, temporomandibular joints and/or associated structures changes. This study aimed at reviewing, using major databases, the effectiveness and safety of sodium hyaluronate in the treatment of temporomandibular joint disorders, aiming at recommending or discarding its clinical use. CONTENTS: The following databases were queried: Medline, via Pubmed (1966-2013), Cochrane Central Registry of Controlled Trials (2012), Embase (1980-2013) and LILACS (1982-2013). The strategy was a search adjusted to each database to identify the largest possible number of studies involving sodium hyalorunate to manage joint temporomandibular disorders. Language was limited to articles published in English. The following keywords were crossed: temporomandibular joint management, versus sodium hyalorunate, versus acute or chronic reducing or nonreducing disk displacement, versus hyaluronic acid, versus osteoarthritis, versus viscosupplementation. Inclusion criteria were randomized, blind or double-blind studies, and case series with 15 or more participants. Exclusion criteria were open label-label studies, animal model studies and articles related to arthrogenous disorders not being treated with sodium hyalorunate infiltration of the temporomandibular joint. Methodological quality of such studies was evaluated and classified according to the level of evidence of the Oxford Center for Evidence Based Medicine. CONCLUSION: According to this review, one may state that sodium hyalorunate is effective and safe, being recommended to manage the following conditions: acute and chronic reducing and nonreducing disk displacement, osteoarthritis and degenerative joint disease.
RESUMO
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.

The aim of this study was to conduct a systematic review to identify the randomized clinical studies that had investigated the following research question: Is the mandibular manipulation technique an effective and safe technique for the treatment of the temporomandibular joint disk displacement without reduction? The systematic search was conducted in the electronic databases: PubMed (Medical Publications), LILACS (Latin American and Caribbean Literature in Health Sciences), EMBASE (Excerpta Medica Database), PEDro (Physiotherapy Evidence Database), BBO (Brazilian Library of Odontology), CENTRAL (Library Cochrane), and SciELO (Scientific Electronic Library Online). The abstracts of presentations in physical therapy meetings were manually selected, and the articles of the ones that meet the requirements were investigated. No language restrictions were considered. Only randomized and controlled clinical studies were included. Two studies of medium quality fulfilled all the inclusion criteria. There is no sufficient evidence to support the effectiveness of the mandibular manipulation therapy, and therefore its use remains questionable. Being minimally invasive, this therapy is attractive as an initial approach, especially considering the cost of the alternative approaches. The analysis of the results suggests that additional high-quality randomized clinical trials are necessary on the topic, and they should focus on methods for data randomization and allocation, on clearly defined outcomes, on a priori calculated sample size, and on an adequate follow-up strategy.

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.
RESUMO
BACKGROUND: Myofascial pain (MP) is a painful condition characterized by pain transmitted from trigger points (TP) within myofascial structures (in the muscles), local or distant from the pain. TPs can produce a characteristic pattern of irradiated pain or autonomic symptoms when stimulated. Cyclobenzaprine, a muscle relaxant that suppresses muscle spasm without interfering with muscle function, is used in clinical management of MP to improve quality of sleep and reduce pain. OBJECTIVES: To assess efficacy and safety of cyclobenzaprine in treating MP. SEARCH STRATEGY: The Pain Palliative and Supportive Care Review Group's Specialised Register, CENTRAL, PubMed, EMBASE, LILACS and Scielo were searched in February 2009. SELECTION CRITERIA: All RCTs and quasi-RCTs reporting use of cyclobenzaprine for treating MP with pain assessment as a primary or secondary outcome. DATA COLLECTION AND ANALYSIS: Two review authors independently screened studies identified, extracted data, assessed trial quality and analyzed results. MAIN RESULTS: We identified two studies with a total of 79 participants. One study, with 41 participants, compared cyclobenzaprine with clonazepam and with placebo. Participants taking cyclobenzaprine had some improvement of pain intensity compared to those on clonazepam, mean difference (MD) -0.25 (95% CI, -0.41 to -0.09; P value 0.002) and placebo, MD -0.25 (95% CI, 0.41 to -0.09; P value 0.002). The other study, with 38 participants, compared cyclobenzaprine with lidocaine infiltration. Thirty days after treatment there were statistically non-significant differences between comparison groups, favoring lidocaine infiltration, for the mean for global pain, MD 0.90 (95% CI -0.35 to 2.15, P value 0.16), and for the mean for pain at digital compression, MD 0.60 (95% CI -0.55 to 1.75, P value 0.30). There were no life-threatening adverse events associated with the medications. AUTHORS' CONCLUSIONS: There was insufficient evidence to support the use of cyclobenzaprine in the treatment of MP. We identified only two small studies in which a total of 35 participants were given cyclobenzaprine, and it was not possible to estimate risks for benefits or harms. Further high quality RCTs of cyclobenzaprine for treating MP need to be conducted before firm conclusions on its effectiveness and safety can be made. Experts in this area should elect cut-off points for participants to identify whether a patient has achieved a clinically relevant reduction of pain (primary outcome), so that their results can be combined easily into future versions of this review.
