    Background Temporomandibular disorders (TMD) is an umbrella term for pain and dysfunction involving the masticatory muscles and the temporomandibular joints (TMJs). TMD is the most common orofacial pain condition. Its prominent features include regional pain in the face and preauricular area......, limitations in jaw movement, and noise from the TMJs during jaw movements. TMD affects up to 15% of adults and 7% of adolescents. Chronic pain is the overwhelming reason that patients with TMD seek treatment. TMD can associate with impaired general health, depression, and other psychological disabilities......, and arthralgia) as well as disorders associated with the TMJ (primarily disc displacements and degenerative disease). As peripheral mechanisms most likely play a role in the onset of TMD, a detailed muscle examination is recommended. The persistence of pain involves more central factors, such as sensitization...

    Temporomandibular disorders (TMD) and primary headaches can be perpetual and debilitating musculoskeletal and neurological disorders. The presence of both can affect up to one-sixth of the population at any one time. Initially, TMDs were thought to be predominantly musculoskeletal disorders, and migraine was thought to be solely a cerebrovascular disorder. The further understanding of their pathophysiology has helped to clarify their clinical presentation. This article focuses on the role of the trigeminal system in associating TMD and migraine. By discussing recent descriptions of prevalence, diagnosis, and treatment of headache and TMD, we will further elucidate this relationship. Copyright © 2016 Elsevier Inc. All rights reserved.

    Etiopathogenesis and clinical management of TMJD integrates a number of medical disciplines. In particular, dentistry, oral - facial surgery, neurology, rheumatology and so on. Nowadays there is no unified strategy for the management of this disease. Most cases of temporomandibular disorder (TMD) respond to simple treatment and the prognosis is good. Symptoms usually remit with simple care. In cases of secondary involvement of temporomandibular joint (TMJ), the prognosis depends on the primary disease. A comprehensive, chronological history and physical and examination of the patient, including dental history and examination, is essential to diagnose the specific condition to decide further investigations, if any, and to provide specific treatment. in severe cases, a joint consultation of a dentist, neurologist and rheumatologist is needed.

OBJECTIVE: Since craniocervical dystonia can involve the same neuromuscular structure as the temporomandibular joint, we sought to assess the correlation between temporomandibular disorders and craniocervical dystonia. METHOD: We applied the Research Diagnostic Criteria for Temporomandibular Disorders to 42 patients with craniocervical dystonia, in order to identify orofacial pain and temporomandibular characteristics on the day of botulinum toxin injection. RESULTS: Twenty-two patients (52.3% reported temporomandibular joint pain; 24 (57.1%, joint sounds; 20 (47.6%, masticatory muscle pain; and 21 (50%, diminished jaw mobility. The patients with oromandibular dystonia presented temporomandibular disorders more frequently than did patients with other types of craniocervical dystonia (p<0.001. CONCLUSION: Temporomandibular disorders occur frequently in patients with oromandibular dystonia. Further studies should address the proper treatment of temporomandibular disorders associated with dystonia.

    Temporomandibular disorders remain a common cause of visits to primary care physicians, internists, pediatricians, and emergency departments. Advances in the clinical diagnosis, radiographic imaging, and classification of these disorders have improved long-term management. There are several types of disorders of the masticatory muscles and the temporomandibular joint as well as associated structures and each may have a complex cause, clinical course, and response to therapy. Host susceptibility plays a role at several stages of these disorders. Future research offers greater possibility in defining this heterogeneous group of disorders and providing more focused and effective treatment strategies. Copyright © 2014 Elsevier Inc.

    Temporomandibular disorders (TMDs) are considered a collection of disorders involving many organic, psychological and psychosocial factors. They can involve the masticatory muscles or the temporomandibular joint (TMJ) and associated structures, or both. It is estimated that 40% to 75% of the population displays at least one sign of the disease and 33% of the population reports at least one symptom. Arthroscopy has been used to reduce signs and symptoms of patients with TMD but the effectiveness has still not been totally explained. To assess the effectiveness of arthroscopy for the management of signs and symptoms in patients with TMDs. The Cochrane Oral Health Group Trials Register (to 23 December 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 4, 2010), MEDLINE via OVID (1950 to 23 December 2010), EMBASE via OVID (1980 to 23 December 2010), LILACS via BIREME Virtual Health Library (1982 to 23 December 2010), Allied and Complementary Medicine Database (AMED) via OVID (1985 to 23 December 2010), CINAHL via EBSCO (1980 to 23 December 2010). There were no restrictions regarding the language or date of publication. Randomized controlled clinical trials of arthroscopy for treating TMDs were included. Two review authors independently extracted data, and three review authors independently assessed the risk of bias of included trials. The authors of the selected articles were contacted for additional information. Seven randomized controlled trials (n = 349) met the inclusion criteria. All studies were either at high or unclear risk of bias. The outcome pain was evaluated after 6 months in two studies. No statistically significant differences were found between the arthroscopy versus nonsurgical groups (standardized mean difference (SMD) = 0.004; 95% confidence interval (CI) -0.46 to 0.55, P = 0.81).

    In 2006, the OPPERA project (Orofacial Pain: Prospective Evaluation and Risk Assessment) set out to identify risk factors for development of painful temporomandibular disorder (TMD). A decade later, this review summarizes its key findings. At 4 US study sites, OPPERA recruited and examined 3,258 community-based TMD-free adults assessing genetic and phenotypic measures of biological, psychosocial, clinical, and health status characteristics. During follow-up, 4% of participants per annum developed clinically verified TMD, although that was a “symptom iceberg” when compared with the 19% annual rate of facial pain symptoms. The most influential predictors of clinical TMD were simple checklists of comorbid health conditions and nonpainful orofacial symptoms. Self-reports of jaw parafunction were markedly stronger predictors than corresponding examiner assessments. The strongest psychosocial predictor was frequency of somatic symptoms, although not somatic reactivity. Pressure pain thresholds measured at cranial sites only weakly predicted incident TMD yet were strongly associated with chronic TMD, cross-sectionally, in OPPERA’s separate case-control study. The puzzle was resolved in OPPERA’s nested case-control study where repeated measures of pressure pain thresholds revealed fluctuation that coincided with TMD’s onset, persistence, and recovery but did not predict its incidence. The nested case-control study likewise furnished novel evidence that deteriorating sleep quality predicted TMD incidence. Three hundred genes were investigated, implicating 6 single-nucleotide polymorphisms (SNPs) as risk factors for chronic TMD, while another 6 SNPs were associated with intermediate phenotypes for TMD. One study identified a serotonergic pathway in which multiple SNPs influenced risk of chronic TMD. Two other studies investigating gene-environment interactions found that effects of stress on pain were modified by variation in the gene encoding catechol O

    Depending on the source and character, pharmacotherapy is one of the most commonly used methods to treat temporomandibular disorders in addition to the use of appliances, physiotherapy, behavioral therapy, and surgical interventions. To decide on the appropriate treatment approach for the treatment of temporomandibular disorders, pharmacotherapeutics should be understood in great detail. As for other pain treatments, pharmacotherapy can be used as a monotherapy or combined with other treatment options in temporomandibular disorders. The aim of the present review is to overview the primary analgesics and myorelaxants used in temporomandibular disorders. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Temporomandibular pain has a musculoskeletal origin because it occurs as a consequence of masticatory muscle function disorder and temporomandibular joint disorder. Most common diagnoses of disorders are disc displacement and osteoarthritis, but their comorbidity can also occur. Pain is the most common symptom, where chronic temporomandibular pain may con- tribute to the occurrence of psychological disorders in the patient population. Splint is the most widespread dental method of treatment but other, noninvasive methods of musculoskeletal pain treatment are also recommended. Electronic axiography is used for visualization of mandibular movements, in particular pathologic sounds in the joints. Mental health, although not so obvious in dental practice, can influence the need of a multidisciplinary approach to the patient with disorder of the temporomandibular joint.

    The aim of this literature systematic review was to evaluate the possible association between malocclusions, orthodontic treatment and development of temporomandibular disorders. A search was carried out on PubMed-Medline database from January 2000 to August 2013 using the keywords "orthodontics and temporomandibular disorders", "orthodontics and facial pain" and "malocclusion and temporomandibular disorders". Human studies included in the study were those assessing signs and symptoms of temporomandibular disorders in relation to orthodontic treatment. A search was carried out on PubMed-Medline database from January 2000 to August 2013 using the keywords "orthodontics and temporomandibular disorders", "orthodontics and facial pain" and "malocclusion and temporomandibular disorders". Human studies included in the study were those assessing signs and symptoms of temporomandibular disorders in relation to orthodontic treatment. The search strategy resulted in 61 articles. After selection according to the inclusion/exclusion criteria 9 articles qualified for the final analysis. The articles which linked orthodontics and development of temporomandibular disorders showed very discrepant results. Some indicated that orthodontic treatment could improve signs and symptoms of temporomandibular disorders, but none of them obtained statistically significant differences. According to the authors examined, there is no evidence for a cause-effect relationship between orthodontic treatment and temporomandibular disorders, or that such treatment might improve or prevent them. More longitudinal studies are needed to verify any possible interrelationship. Key words:Malocclusion and temporomandibular disorders, orthodontics and facial pain, orthodontics and temporomandibular disorders, temporomandibular disorders, temporomandibular dysfunction.

    The aim of this article was to review the literature about temporomandibular disorders and bruxism and their relationships in children and adolescents. The literature was searched using Medline, ISI, Cochrane Library, Scielo and the Internet, from March 1970 to the end of June 2007. The inclusion criteria were: they evaluated a possible association between TMD and bruxism, and they dealt with child and/or adolescent samples. Furthermore, interim reports, related Internet sites and chapters in textbooks were considered. From 64 records found, 30 fulfilled the inclusion criteria. The prevalence of temporomandibular disorders in children and adolescent varies widely in the literature. Temporomandibular disorders are often defined on the basis of signs and symptoms, of which the most common are: temporomandibular joint sounds, impaired movement of the mandible, limitation in mouth opening, preauricular pain, facial pain, headaches and jaw tenderness on function, having mainly a mild character, fluctuation and progression to severe pain and dysfunction is rare. One of the possible causal factors suggested that temporomandibular disorders in children is a functional mandibular overload variable, mainly bruxism. Bruxism, defined as the habitual nonfunctional forceful contact between occlusal tooth surfaces, is involuntary, excessive grinding, clenching or rubbing of teeth during nonfunctional movements of the masticatory system. Its etiology is still controversial but the multifactorial cause has been attributed, including pathophysiologic, psychologic and morphologic factors. Moreover, in younger children, bruxism may be a consequence of the masticatory neuromuscular system immaturity. Complications include dental attrition, headaches, temporomandibular disorders and masticatory muscle soreness. Some studies have linked oral parafunctional habits to disturbances and diseases of the temporomandibular joint, mainly bruxism, suggesting its association with temporomandibular

    Data sourcesMedline, Scopus and Google Scholar.Study selectionTwo reviewers selected studies independently. English language clinical studies assessing the association between temporomandibular disorders (TMD) and features of dental occlusion were considered.Data extraction and synthesisStudy quality was assessed based on the Newcastle-Ottawa Scale (NOS) and a narrative synthesis was presented.ResultsIn all 25 studies (17 case-control, eight comparative) were included. Overall there was a high variability between occlusal features and TMD diagnosis. Findings were consistent with a lack of clinically relevant association between TMD and dental occlusion. Only two studies were associated with TMD in the majority (≥50%) of single variable analyses in patient populations. Only mediotrusive interferences are associated with TMD in the majority of multiple variable analyses.ConclusionsThe findings support the absence of a disease-specific association, there is no ground to hypothesise a major role for dental occlusion in the pathophysiology of TMDs. Dental clinicians are thus encouraged to move forward and abandon the old-fashioned gnathological paradig.

    Full Text Available The temporomandibular joint has a very important role in the stomatognathic system. Its main function is for the opening and closing movement, mastication, and speech. It is located anterior to the ear. The temporomandibular joint connects maxilla and mandible through the articular fossa, hence the slightest change that happens would cause serious matters such as pain, exiting, speech disorder, difficulty in opening and closing movement, headache, and even trismus. In a child or an adolescent, the symptoms are often vague; everything is interpreted as “pain”. This is probably why temporomandibular disorder are often undetected by dentists. Therefore, patience and accuracy is needed to determine the actual disorder through means of clinical and radiographic examination. The radiographic examination suitable for child is the transcranial projection. This projection is believed to be more accurate amongst other projection for child patients.

Material and Methods: A sample of 154 subjects participated in this study. All subjects underwent a series of physical tests and electromyographic assessment (i.e. head and neck posture, maximal cervical muscle strength, cervical flexor and extensor muscles endurance, and cervical flexor muscle performance to determine cervical musculoskeletal impairments. Results: A strong relationship between neck disability and jaw disability was found (r = 0.82. Craniocervical posture was statistically different between patients with myogenous Temporomandibular Disorders (TMD and healthy subjects. However, the difference was too small (3.3º to be considered clinically relevant. Maximal cervical flexor muscle strength was not statistically or clinically different between patients with TMD and healthy subjects. No statistically significant differences were found in electromyographic activity of the sternocleidomastoid or the anterior scalene muscles in patients with TMD when compared to healthy subjects while executing the craniocervical flexion test (P = 0.07. However, clinically important effect sizes (0.42 - 0.82 were found. Subjects with TMD presented with reduced cervical flexor as well as extensor muscle endurance while performing the flexor and extensor muscle endurance tests when compared to healthy individuals. Conclusions: Subjects with Temporomandibular Disorders presented with impairments of the cervical flexors and extensors muscles. These results could help guide clinicians in the assessment and prescription of more effective interventions for individuals with Temporomandibular Disorders.

    Full Text Available Temporomandibular joint (TMJ forms an integral functional part of stomatognathic system. Position, shape, structure and function of teeth have an influence on the proper functioning and health of TMJ. But a problem associated with TMJ is often neglected, and treatment for it is mostly restricted to palliative therapy. A proper understanding of the underlying cause of temporomandibular joint disorder (TMD is necessary to device a proper treatment plan. Etiology of TMDs varies from idiopathic reasons to systemic disorders. The option of Gnathological splint is a conservative, safe and an effective mode of therapy for TMDs caused by occlusal discrepancies (fulcrum/interferences.

    Temporomandibular disorders are the most common cause of chronic orofacial pain, but, except where they occur subsequent to trauma, their cause remains unknown. This cross-sectional study assessed chewing function (habitual chewing side) and the differences of the chewing side and condylar path and lateral anterior guidance angles in participants with chronic unilateral temporomandibular disorder. This is the preliminary report of a randomized trial that aimed to test the effect of a new occlusal adjustment therapy. The masticatory function of 21 randomly selected completely dentate participants with chronic temporomandibular disorders (all but one with unilateral symptoms) was assessed by observing them eat almonds, inspecting the lateral horizontal movement of the jaw, with kinesiography, and by means of interview. The condylar path in the sagittal plane and the lateral anterior guidance angles with respect to the Frankfort horizontal plane in the frontal plane were measured on both sides in each individual. Sixteen of 20 participants with unilateral symptoms chewed on the affected side; the concordance (Fisher's exact test, P = .003) and the concordance-symmetry level (Kappa coefficient κ = 0.689; 95% confidence interval [CI], 0.38 to 0.99; P = .002) were significant. The mean condylar path angle was steeper (53.47(10.88) degrees versus 46.16(7.25) degrees; P = .001), and the mean lateral anterior guidance angle was flatter (41.63(13.35) degrees versus 48.32(9.53) degrees P = .036) on the symptomatic side. The results of this study support the use of a new term based on etiology, "habitual chewing side syndrome", instead of the nonspecific symptom-based "temporomandibular joint disorders"; this denomination is characterized in adults by a steeper condylar path, flatter lateral anterior guidance, and habitual chewing on the symptomatic side.

    Temporomandibular disorders (TMD) are a heterogeneous group of musculoskeletal and neuromuscular conditions involving the temporomandibular joint complex, and surrounding musculature and osseous components. TMD affects up to 15% of adults, with a peak incidence at 20 to 40 years of age. TMD is classified as intra-articular or extra-articular. Common symptoms include jaw pain or dysfunction, earache, headache, and facial pain. The etiology of TMD is multifactorial and includes biologic, environmental, social, emotional, and cognitive triggers. Diagnosis is most often based on history and physical examination. Diagnostic imaging may be beneficial when malocclusion or intra-articular abnormalities are suspected. Most patients improve with a combination of noninvasive therapies, including patient education, self-care, cognitive behavior therapy, pharmacotherapy, physical therapy, and occlusal devices. Nonsteroidal anti-inflammatory drugs and muscle relaxants are recommended initially, and benzodiazepines or antidepressants may be added for chronic cases. Referral to an oral and maxillofacial surgeon is indicated for refractory cases.

    This study investigated the association between craniofacial morphology and temporomandibular disorders in adults. The influence of different craniofacial morphologies on painful temporomandibular disorders was also evaluated. A total of 200 subjects were selected, including 100 with temporomandibular disorders (TMD) and 100 without TMD (control), diagnosed by research diagnostic criteria for temporomandibular disorders. All subjects were submitted to lateral cephalometric radiographs, and classified as brachyfacial, mesofacial, or dolichofacial by Ricketts' analysis. Data were analysed by Tukey-Kramer and Chi-square tests. No association between craniofacial morphology and TMD was found (P = 0.6622). However, brachyfacial morphology influences the presence of painful TMD (P = 0.0077). Craniofacial morphology is not related to temporomandibular disorders in general.

    Changing lifestyles, decreasing physical activity, which is increasing the number of degenerative joint diseases of various etiology, and certain dental procedures are increasing the number of patients complaining of pain in their temporomandibular joints. The aim of the study was to assess the benefits of comprehensive physiotherapy sessions in order to decrease the number of temporomandibular joint problems, thereby improving the patient's quality of life. An examination by a dentist determined each patient's treatment plan, which consisted of a medical exam, physical therapy and education. Each form of treatment was applied 10 times at intervals of 7-14 days. The main goal of the therapeutic physical education was to redress the muscle imbalance in the mandibular joint. This was achieved by restoring balance between the masticatory muscles, along with releasing the spastic shrouds found in the masticatory muscles. The aim of education was to teach the patient exercises focused on the temporomandibular joint and masticatory muscles. The intensity of the exercises and their composition were individually adjusted and adapted to their current state. Physical therapy consisted of the application of pulsed magnetic therapy, laser therapy, and non-invasive positive thermotherapy. The above procedure was conducted on a therapeutic group of 24 patients (3 men and 20 women). In the course of therapy, there were no complications, and all patients adhered to the prescribed regime. None reported any side effects. The mean treatment duration was 123 +/- 66 days. The outcome of the therapy was evaluated as described in the methodology, the degree of pain affecting the joint, and the opening ability of the mouth. In both parameters, there was a significant decline in patient pain. In a study devoted to tactics of rehabilitation treatment for temporomandibular joint disorders, the need for comprehensive long-term therapy, involving education, and learning proper chewing habits

    Recently, some published studies show there is a multifactorial origin for Temporomandibular Disorders, but the dental occlusion's contribution to the development of Temporomandibular Disorders, and how it may influence the adaptive capacity of the Stomatognathic system, it's still unclear. The aim of this study is to evaluate the correlation between the Occlusion Time and Temporomandibular Disorders. A total of 54 patients were enrolled in the study (24 males and 30 females, mean age 27.94 ± 8.21 years). The TMD group (8 males and 10 females) consisted of subjects who presented with at least 1 of the following signs of Temporomandibular Disorders: Temporomandibular Joint sounds (clicking or crepitation), Temporomandibular Joint locking episodes, limited mandibular opening, painful limitation of mandibular movements, pain to palpation of the Temporomandibular Joint or of the masticatory muscles. The control group (16 males and 20 females) presented as free from Temporomandibular Disorders. The T-Scan III computerized occlusal analysis system was to record the subjects' Occlusion. Times during eight mandibular opening-closing movements. The two-ways ANOVA test analyzed the variations for group and sex, showing that the TMD group mean Occlusion Time (0.64 ± 0.21s) was statistically significantly longer than the control group mean Occlusion Time (0.45 ± 0.17s) (pTMJ problems has to be carefully considered as adjunctive instrumental device.

    Full Text Available INTRODUCTION: The possibility that orthodontic treatment in childhood might be a risk factor for the development of temporomandibular disorders (TMD later in life has been an issue of great controversy in dental literature. OBJECTIVE: To determine a possible negative or positive correlation between orthodontic treatment and TMD by presenting the results and conclusions from a number of key-papers dealing with this subject. RESULTS AND CONCLUSION: According to current knowledge, there is no scientific evidence to support that orthodontic treatment is a risk factor for the development of TMD. On the other hand, there is some evidence to support that a proper orthodontic treatment performed in childhood might have a positive effect upon the functional status of the masticatory system later in life.

    Temporomandibular joint (TMJ) is a complex, sensitive, and highly mobile joint. Millions of people suffer from temporomandibular disorders (TMD) in USA alone. The TMD treatment options need to be looked at more fully to assess possible improvement of the available options and introduction of novel techniques. As reconstruction with either partial or total joint prosthesis is the potential treatment option in certain TMD conditions, it is essential to study outcomes of the FDA approved TMJ implants in a controlled comparative manner. Evaluating the kinetics and kinematics of the TMJ enables the understanding of structure and function of normal and diseased TMJ to predict changes due to alterations, and to propose more efficient methods of treatment. Although many researchers have conducted biomechanical analysis of the TMJ, many of the methods have certain limitations. Therefore, a more comprehensive analysis is necessary for better understanding of different movements and resulting forces and stresses in the joint components. This article provides the results of a state-of-the-art investigation of the TMJ anatomy, TMD, treatment options, a review of the FDA approved TMJ prosthetic devices, and the TMJ biomechanics.

    Appropriate management of temporomandibular disorders (TMD) requires an understanding of the underlying dysfunction associated with the temporomandibular joint (TMJ) and surrounding structures. A comprehensive examination process, as described in part 1 of this series, can reveal underlying clinical findings that assist in the delivery of comprehensive physical therapy services for patients with TMD. Part 2 of this series focuses on management strategies for TMD. Physical therapy is the preferred conservative management approach for TMD. Physical therapists are professionally well-positioned to step into the void and provide clinical services for patients with TMD. Clinicians should utilize examination findings to design rehabilitation programs that focus on addressing patient-specific impairments. Potentially appropriate plan of care components include joint and soft tissue mobilization, trigger point dry needling, friction massage, therapeutic exercise, patient education, modalities, and outside referral. Management options should address both symptom reduction and oral function. Satisfactory results can often be achieved when management focuses on patient-specific clinical variables. PMID:24976744

    List, Thomas; Jensen, Rigmor Højland

    2017-06-01

    Background Temporomandibular disorders (TMD) is an umbrella term for pain and dysfunction involving the masticatory muscles and the temporomandibular joints (TMJs). TMD is the most common orofacial pain condition. Its prominent features include regional pain in the face and preauricular area, limitations in jaw movement, and noise from the TMJs during jaw movements. TMD affects up to 15% of adults and 7% of adolescents. Chronic pain is the overwhelming reason that patients with TMD seek treatment. TMD can associate with impaired general health, depression, and other psychological disabilities, and may affect the quality of life of the patient. Assessment Evaluations indicate that the recently published Diagnostic Criteria for TMD (DC/TMD) are reliable and valid. These criteria cover the most common types of TMD, which include pain-related disorders (e.g., myalgia, headache attributable to TMD, and arthralgia) as well as disorders associated with the TMJ (primarily disc displacements and degenerative disease). As peripheral mechanisms most likely play a role in the onset of TMD, a detailed muscle examination is recommended. The persistence of pain involves more central factors, such as sensitization of the supraspinal neurons and second-order neurons at the level of the spinal dorsal horn/trigeminal nucleus, imbalanced antinociceptive activity, and strong genetic predisposition, which also is included in DC/TMD. Conclusion The etiology is complex and still not clearly understood, but several biological and psychosocial risk factors for TMD have been identified. Several studies indicate that patients with TMD improve with a combination of noninvasive therapies, including behavior therapy, pharmacotherapy, physical therapy, and occlusal appliances. More stringently designed studies, however, are needed to assess treatment efficacy and how to tailor treatment to the individual patient.

    Abrahamsson, Cecilia

    2013-01-01

    About 30% of individuals in the Swedish population will at some stage during life have treatment with orthodontic appliances. In more severe cases, when orthodontic treatment is not considered sufficient enough to correct the malocclusion, the orthodontic treatment is combined with orthognathic surgery. For these cases, a satisfying jaw relation is achieved by surgically moving the maxilla and/or the mandible into a pre-planned position. Patients due to be treated with orthognathic surgery often suffer from an impaired masticatory function, symptoms from the masticatory muscles or temporomandibular joints (temporomandibular disorders), headaches as well as dissatisfaction with their facial aesthetics. Since orthognathic treatment is expensive, in many cases arduous to the patient and not without complications, it is important to assess the treatment outcome and if this is satisfying for the patients. Previous studies that have examined the outcome after orthognathic treatment have had diverging study designs and have come to different conclusions with regard to both temporomandibular disorders and masticatory function. The overall aim of this thesis was to assess and compare the frequencies of temporomandibular disorders and the masticatory function in patients with dentofacial deformities before and after orthognathic treatment. THE THESIS IS BASED ON THE FOLLOWING STUDIES: Paper I is a systematic literature review aiming to, in an evidence-based approach, answer the question whether orthognathic treatment affects the prevalence of signs and symptoms of temporomandibular disorders. The review encompasses the period from January 1966 to April 2006 and was further extended to May 2013 in the frame story of this thesis. CONCLUSIONS IN PAPER I AND THE COMPLEMENTARY SURVEY: There is insufficient scientific evidence for a decrease of sub diagnoses of temporomandibular disorders after orthognathic treatment. There is limited scientific evidence for a reduction of

    Full Text Available The aim of this study is to review the existing literature about temporomandibular disorders(TMD and parafunctional habits (bruxism and their relationship in children and adolescents,which is still controversial. TMD is a collective term used to identify a group ofmusculoskeletal conditions of the temporomandibular region. Bruxism defined as the habitual nonfunctional forceful contact between occlusal tooth surfaces. Some studies have linked oral parafunctional habits to TMD, whereas others did not observe this relationship.The role of bruxism -as is currently described- can be considered a controversial and unresolved issue. Taking all evidence together, the authors suggest that there is not any clear relationship between bruxism and TMD.

    In 2012, the recognition of the specialty of Temporomandibular Disorders and Orofacial Pain completed ten years. Given this scenario, it is extremely important to track the current situation of this field of knowledge in Brazil, specifically in the area of research and training. We hope to discuss the importance of the recognition of this specialty and the inclusion of these subjects in undergraduate programs in Dentistry. The objective of this study is to perform a bibliometric survey of researches regarding Temporomandibular Disorders and Orofacial Pain conducted in the country, determine the number of specialization courses in Orofacial Pain and the number of specialists in the field. The bibliometric survey was conducted based on the Dissertations Portal of Coordination for the Improvement of Higher education Personnel (CAPES) and on PubMed. The panorama of the field of Orofacial Pain and Temporomandibular disorders in Brazil was determined by searching on the website of the Brazilian Council of Dentistry. We found 731 theses and dissertations with Temporomandibular Disorders and Orofacial Pain as the main subjects; 81 accredited/recognized Courses on Orofacial Pain and Temporomandibular Dysfunction completed; 8 accredited/recognized Specialization Courses on Orofacial Pain and Temporomandibular Dysfunction still in progress, and 1,064 registered specialists in Orofacial Pain and Temporomandibular Dysfunction in the Brazilian Council of Dentistry. Search in the PUBMED database yielded 576 articles published with the participation of Brazilian researchers as first authors and/or co-authors in the period from 2000 to 2013. From this amount, only 5 were published in Portuguese, while all the others were published in english. We can also notice that the number of published articles increases over time. The number of researches related to temporomandibular disorders has increased over the last ten years, as well as the number of specialization courses and the number

    Temporomandibular disorders are a common musculoskeletal condition causing severe pain, physical and psychological disability. The effect and evidence of osteopathic manipulative treatment and osteopathy in the cranial field is scarce and their use are controversial. The purpose of this pilot study was to evaluate the effectiveness of osteopathic manipulative treatment and osteopathy in the cranial field in temporomandibular disorders. A randomized clinical trial in patients with temporomandibular disorders was performed. Forty female subjects with long-term temporomandibular disorders (>3 months) were included. At enrollment, subjects were randomly assigned into two groups: (1) osteopathic manipulative treatment group (20 female patients) and (2) osteopathy in the cranial field group (20 female patients). Examination was performed at baseline (E0) and at the end of the last treatment (E1), consisting of subjective pain intensity with the Visual Analog Scale, Helkimo Index and SF-36 Health Survey. Subjects had five treatments, once a week. 36 subjects completed the study (33.7 ± 10.3 y). Patients in both groups showed significant reduction in Visual Analog Scale score (osteopathic manipulative treatment group: p = 0.001; osteopathy in the cranial field group: pmanipulative treatment group: p = 0.02; osteopathy in the cranial field group: p = 0.003) and a significant improvement in the SF-36 Health Survey - subscale "Bodily Pain" (osteopathic manipulative treatment group: p = 0.04; osteopathy in the cranial field group: p = 0.007) after five treatments (E1). All subjects (n = 36) also showed significant improvements in the above named parameters after five treatments (E1): Visual Analog Scale score (pmanipulative treatment and osteopathy in the cranial field as an effective treatment modality in patients with temporomandibular disorders. The positive results in both treatment groups should encourage further research on osteopathic

    Temporomandibular disorder is an umbrella term for various clinical problems affecting the muscles of mastication, temporomandibular joint and associated structures. This disorder has a multifactor etiology, with oral parafunctional habits considered an important co-factor. Among such habits, sleep bruxism is considered a causal agent involved in the initiation and/or perpetuation of temporomandibular disorder. That condition can result in pain otologic symptoms. The aim of the present study was to investigate the relationship between temporomandibular disorder and both otologic symptoms and bruxism. A total of 776 individuals aged 15 years or older from urban areas in the city of Recife (Brazil) registered at Family Health Units were examined. The diagnosis of temporomandibular disorder was determined using Axis I of the Research Diagnostic Criteria for temporomandibular disorders, addressing questions concerning myofascial pain and joint problems (disk displacement, arthralgia, osteoarthritis and osteoarthrosis). Four examiners had previously undergone training and calibration exercises for the administration of the instrument. Intra-examiner and inter-examiner agreement was determined using the Kappa statistic. Individuals with a diagnosis of at least one of these conditions were classified as having temporomandibular disorder. The diagnosis of otologic symptoms and bruxism was defined using the same instrument and a clinical exam. Among the individuals with temporomandibular disorder, 58.2% had at least one otologic symptom and 52% exhibited bruxism. Statistically significant associations were found between the disorder and both otologic symptoms and bruxism (p<0.01 for both conditions; OR=2.12 and 2.3 respectively). Otologic symptoms and bruxism maintained statistical significance in the binary logistic regression analysis, which demonstrated a 1.7 fold and twofold greater chance of such individuals have temporomandibular disorder, respectively.

    Full Text Available Because nonespecific symptoms and signs are associated with others well-established in the temporomandibular disorders, it is difficult for the clinician to decide what symptoms and signs should be considered during the diagnosis and the treatment plan. Therefore, the aim of this literature review was to evaluate the prevalence of aural symptoms (otalgias, tinnitus, dizziness and deafness in patients with orofacial pain. Although several hypotheses have been proposed to explain the association between aural symptoms and temporomandibular disorders, the results of the previous studies differed in magnitude. For this reason, it is difficult to establish the prevalence of these aural symptoms concomitantly with temporomandibular disorders. Moreover, such relationship does not necessarily imply a cause-effect relationship. Because of the diagnosis complexity, different treatments must be considered, so the nonespecific symptoms of temporomandibular disorders can be effectively controlled as well. It is crucial for the the clinician to be aware of the possible etiology of aural symptoms, so he should determine if such symptoms may be associated with temporomandibular disorders and thus include them in the treatment.

MATERIAL AND METHODS: Speech and dental occlusal characteristics were assessed in 152 Brazilian children (78 boys and 74 girls, aged 8 to 12 (mean age 10.05 ± 1.39 years with or without TMD signs and symptoms. The clinical signs were evaluated using the Research Diagnostic Criteria for TMD (RDC/TMD (axis I and the symptoms were evaluated using a questionnaire. The following groups were formed: Group TMD (n=40, TMD signs and symptoms (Group S and S, n=68, TMD signs or symptoms (Group S or S, n=33, and without signs and symptoms (Group N, n=11. Articulatory speech disorders were diagnosed during spontaneous speech and repetition of the words using the "Phonological Assessment of Child Speech" for the Portuguese language. It was also applied a list of 40 phonological balanced words, read by the speech pathologist and repeated by the children. Data were analyzed by descriptive statistics, Fisher's exact or Chi-square tests (α=0.05. RESULTS: A slight prevalence of articulatory disturbances, such as substitutions, omissions and distortions of the sibilants /s/ and /z/, and no deviations in jaw lateral movements were observed. Reduction of vertical amplitude was found in 10 children, the prevalence being greater in TMD signs and symptoms children than in the normal children. The tongue protrusion in phonemes /t/, /d/, /n/, /l/ and frontal lips in phonemes /s/ and /z/ were the most prevalent visual alterations. There was a high percentage of dental occlusal alterations. CONCLUSIONS: There was no association between TMD and speech disorders. Occlusal alterations may be factors of influence, allowing distortions and frontal lisp in phonemes /s/ and /z/ and inadequate tongue position in phonemes /t/; /d/; /n/; /l/.

    Magnetic resonance (MR) imaging of the temporomandibular joint (TMJ) has now been established as a procedure of choice in the evaluation of TMJ disorders. In this study, we evaluated the dynamics of TMJ motion on MR imaging, which resembles arthrography. Sixty-eight TMJs in 38 symptomatic patients and one healthy volunteer were examined using pseudodynamic images with gradient echo sequences using a 0.5 Tesla MR unit and 8 cm circular planar surface coil. For depiction of each compartment of the meniscus, the optimum sequence was 200/15/2 (TR/TE/excitations) with 50 deg or 60 deg flip angle in gradient refocused acquisition in steady-state (GRASS) sequences. Three contiguous slices on sagittal MR images were routinely obtained at 14-18 different phases of the opening cycle and displayed in closed-loop cine fashion. Internal derangement was observed in 57% of 68 joints. The most common type was anterior meniscal displacement without reduction. Sideway and rotational displacements, observed in 10% each, were noted on both sagittal multislice images and axial reference images. As a pseudodynamic MR technique, jaw movement specifically designed to check bite procedure to adjust splints is useful for detecting the exact time of meniscal redisplacement on the second click. After conservative therapy for arthrosis, pseudodynamic MR provided information on changes in the meniscus and condylar relationship. Pseudodynamic MR with multiple phases is suitable for evaluating subtle motion abnormality of the meniscus and for post-therapeutic monitoring. (author).

    To assess if subjects with a clinical diagnosis of temporomandibular disorders (TMDs) have a similar prevalence of orthodontic history as a population of TMD-free individuals and to assess if those subjects who have a history of ideal orthodontics have fewer symptoms than those with a history of nonideal orthodontics. Two groups of age- and sex-matched individuals belonging to either a study ("TMD") or a control group were recruited. Subjects who underwent orthodontic treatment were classified as having a history of ideal or nonideal orthodontics based on the current presence of normal values in five reference occlusal features. The correlation with a history of orthodontic treatment was not clinically significant for any of the TMD diagnoses (ie, muscle pain, joint pain, disc displacement, arthrosis), with Phi (Φ) coefficient values within the -0.120 to 0.058 range. Within the subset of patients with a history of orthodontics, the correlation of ideal or nonideal orthodontic treatment with TMD diagnoses was, in general, not clinically relevant or was weakly relevant. Findings confirmed the substantial absence of clinically significant effects of orthodontics as far as TMD is concerned. The very low correlation values of a negative or positive history of ideal or nonideal orthodontics with the different TMD diagnoses suggest that orthodontic treatment could not have a true role for TMD.

    Full Text Available Patients with temporomandibular disorders (TMD frecuently present psychological and psychiatric problems. These patients often show increased somatization, depression, anxiety, stress reaction and catastrophism, wich plays a role in the predisposition, initiation and perpetuation of TMD and treatment response. This review presents thaerapeutic options that compromise the psychological axis of patients with TMD, wich primarily seek to reduce the anxiety and the emotional stress present, modify different perceptions of pain and coping. There are different posibilities, within wich are: patient education, identifying situations that increase the tension to avoid them, teaching relaxation techniques such as biofeedback, hipnosis and yoga. As for psychological treatment, the most common for chronic orofacial pain is cognitive behavioral therapy (CBT. The appropriate and effective psychological intervention can reduce TMD pain, decreasing the probability that the symptoms become more complex. Within psychological treatment options for TMD, conservative standard treatment (education, self-instruction, avoidance of painful movements, soft diet, even the shortest, may be sufficient in the short term for most patients with TMD, especially in cases of acute conditions. The addition of CBT, by a specialist, gives coping skills that will add to the effectiveness, especially in chronic cases, obtaining better results in the long term.

    Background Many dentists believe that sleep bruxism (SB) is a pathogenic factor in myofascial temporomandibular disorder (TMD), but almost all supportive data rely on patients’ self-reports rather than on direct observation. Methods The authors administered a structured self-report interview to determine whether a large and well-characterized sample of patients with myofascial TMD (124 women) experienced SB more often than did matched control participants (46 women). The authors then used data from a two-night laboratory-based polysomnographic (PSG) study to determine whether the case participants exhibited more SB than the control participants. Results The results of independent sample t tests and χ2 analyses showed that, although self-reported rates of SB were significantly higher in case participants (55.3 percent) than in control participants (15.2 percent), PSG-based measures showed much lower and statistically similar rates of SB in the two groups (9.7 percent and 10.9 percent, respectively). Grinding noises were common in both case participants (59.7 percent) and control participants (78.3 percent). Conclusions Most case participants did not exhibit SB, and the common belief that SB is a sufficient explanation for myofascial TMD should be abandoned. Clinical Implications Although other reasons to consider treating SB may exist, misplaced concern about SB’s sustaining or exacerbating a chronic myofascial TMD condition should not be used to justify SB treatment.

    Temporomandibular disorders (TMD) relate to discomfort of the temporomandibular joint (TMJ). The disorder is multifactorial with a degree of psychogenic influence varying throughout an individual's life with phases of symptoms affecting the quality of life. In an attempt to treat this complex group of disorders many treatment modalities have been identified some of which are also considered in other Cochrane reviews. The disorder also has a normal cycle of events appearing to spontaneously improve without treatment. To establish the effectiveness of orthodontic intervention in reducing symptoms in patients with TMD (compared with any control group receiving no treatment, placebo treatment or reassurance) and to establish if active orthodontic intervention leads to TMD. The Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE and EMBASE were searched. Handsearching of orthodontic journals and other related journals was undertaken in keeping with the Cochrane Collaboration handsearching programme. No language restrictions were applied. Authors of any studies were identified, as were experts offering legal advice, and contacted to identify unpublished trials. Most recent search: 13th April 2010. All randomised controlled trials (RCTs) including quasi-randomised trials assessing orthodontic treatment for TMD were included. Studies with adults aged equal to or above 18 years old with clinically diagnosed TMD were included. There were no age restrictions for prevention trials provided the follow-up period extended into adulthood. The inclusion criteria required reports to state their diagnostic criteria for TMD at the start of treatment and for participants to exhibit two or more of the signs and/or symptoms. The treatment group included treatment with appliances that could induce stable orthodontic tooth movement. Patients receiving splints for 8 to 12 weeks and studies involving surgical intervention (direct exploration/surgery of the joint and

    This study aims to present both the features of 124 consecutive patients with temporomandibular disorders (TMDs) and the results of a reversible, conservative, and low-tech treatment. One hundred fifty-eight records of consecutive patients treated in School of Dentistry at the Univag-University Center in Várzea Grande-MT, Brazil, 124 of whom were considered TMD patients, were examined. The following data were obtained: gender, age, main complaint, diagnosis, co-morbidities, type of treatment performed, and treatment results. The patients who received a successful treatment were contacted for reevaluation four to six years after the conclusion of treatment. Pain was the main complaint for 92.7 percent of the patients. The majority of patients were female (female:male ratio of 4.1:1), with a peak age range between 20 and 30 years. Roughly 59.7 percent of the patients were diagnosed as having a muscular TMD, 12.9 percent as an articular TMD, and 27.4 percent as a mixed TMD. The success rate for treatment was 91.7 percent, and there was a tendency toward the long-term maintenance of good results. The features of the 124 TMD patients treated were similar to those reported in the literature with regard to gender, age, and diagnostic prevalence. Most of the disorders were of a muscular origin, and there was a predominance of women between 20 and 30 years of age. The conservative, reversible, and low-tech treatment success rate for TMD can reach values above 90 percent. Therefore, there is no need for invasive, irreversible, expensive, or high-tech treatments for the majority of patients. The majority of TMD patients can benefit from reversible, conservative, and low-tech treatments such as parafunction control and therapeutic exercises that can be performed by any clinician once an accurate diagnosis has been made.

    Full Text Available AIM: To identify the relationship between anterior disc displacement and global posture (plantar arches, lower limbs, shoulder and pelvic girdle, vertebral spine, head and mandibles. Common signs and symptoms of anterior disc displacement were also identified. INTRODUCTION: Global posture deviations cause body adaptation and realignment, which may interfere with the organization and function of the temporomandibular joint. METHODS: Global posture evaluation was performed in a group of 10 female patients (20 to 30 years of age with temporomandibular joint disc displacement and in a control group of 16 healthy female volunteers matched for age, weight and height. Anterior disc displacement signs, symptoms and the presence of parafunctional habits were also identified through interview. RESULTS: Patients with disc displacement showed a higher incidence of pain in the temporomandibular joint area, but there were no differences in parafunctional habits between the groups. In the disc displacement group, postural deviations were found in the pelvis (posterior rotation, lumbar spine (hyperlordosis, thoracic spine (rectification, head (deviation to the right and mandibles (deviation to the left with open mouth. There were no differences in the longitudinal plantar arches between the groups. CONCLUSION: Our results suggest a close relationship between body posture and temporomandibular disorder, though it is not possible to determine whether postural deviations are the cause or the result of the disorder. Hence, postural evaluation could be an important component in the overall approach to providing accurate prevention and treatment in the management of patients with temporomandibular disorder.

    The influence of hormonal fluctuations on pain and mastication was evaluated in patients with painful temporomandibular disorder (TMD) symptoms. Fifty women were assigned to menstrual cycle and oral contraceptive groups (n = 25). Their TMD was diagnosed by Research Diagnostic Criteria for Temporomandibular Disorders. Pain levels, maximum oclusal force (MOF), and masticatory performance (MP) were measured in all menstrual cycle phases. A lower pain level was observed in the ovulatory phase when compared to menstrual and luteal phases (P = .02). No differences were found regarding MOF (P = .20) or MP (P = .94). Hormonal fluctuations intensify pain in women with symptomatic TMD without impairing mastication.

    Full Text Available Masticatory system is a complex functional unit of the body responsible for mastication, speech, and deglutition process. Temporomandibular disorders (TMD is used to describe all functional disturbances of the masticatory system. The etiology of TMD is multifactorial, such as occlusal disharmony and emotional stress. The relationship between occlusion and TMD has been highly debated in dentistry, one of the occlusal factors is the occlusal scheme. Occlusal schemes are defined as bilateral canine guidance, unilateral canine guidance, group function and balanced occlusion. However, studies about the relationship of occlusal schemes and the occurrence of the TMD are still limited and remained controversial. Objective: To investigate the relationship of occlusal schemes witht he occurrence of TMD. Methods: A cross-sectional study was conducted at the Faculty of Dentistry, Uniiversitas Indonesia. A total of 127 students were included in this study. Subjects were examined based on Clinical Helkimo Index and divided into TMD and non-TMD groups. Subjects were categorized as non-TMD groups if the value of the clinical Helkimo index was 0 and as TMD group when the value ranged between 1-25. Results: Balanced occlusion schemes has a greater risk of TMD occurrence with odds ratio value 5.6 and 95% confidence interval 1.188 to 26.331 (p=0.021. Conclusion: Balanced occlusion has a significant relationship with the occurrence of TMD.

    Temporomandibular disorders (TMDs) are prevalent multifactorial pathologies in which the actual role of the cervical region position is controversial. To analyze the relationship between the position of the upper cervical rachis and the symptoms of TMD. Sixty women were recruited to this study. All of them completed a questionnaire and were subjected to a temporomadibular exploration to create two different groups: a TMD Group (n= 30) - women who suffered TMD symptoms according to the evaluation; and a control group (n= 30) - women who were free from TMD symptoms. Two X-ray examinations were performed in all the women: a lateral one and a frontal one with mouth open to assess the C1-C0 distance and the craniocervical angle. ANOVA showed that the TMD and control women had similar C1-C0 distances and craniocervical angles (p> 0.05). Pearson correlation did not indicate any relationship between the craniocervical position and the symptomatology of TMD (r=- 0.070). TMD symptomatology is unrelated to alterations in craniocervical position (C0-C1 distance and craniocervical angle). Women with and without TMD showed a similar prevalence of alteration in the craniocervical position.

    This study aimed to evaluate the characteristics of deglutition in children having or not temporomandibular disorders (TMD) or signs and/or symptoms of TMD. The sample comprised 152 children aged from 8 to 12 years (78 males and 74 females, mean age 10.05+/-1.39 years). The clinical signs were evaluated using the axis I of the Research Diagnostic Criteria for TMD (RDC/TMD) and the symptoms, using a questionnaire. Patients were divided into the following groups: Group TMD (N.=40), signs and symptoms of TMD (Group S and S, N.=68), signs or symptoms of TMD (Group S or S, N.=33) and without signs and symptoms (Group N, N.=11). Characteristics of orofacial structures such as occlusion, tongue, lingual frenulum, lips and mentalis muscle were evaluated. Myofunctional evaluation during deglutition with solid (bread) and liquid (water) was also performed. A high prevalence of abnormal deglutition was found, with similar proportion in groups. Alterations in lips, mentalis muscle and tongue in swallowing was significantly smaller in Group N than in the other groups. The proportions of children with lower lip interposition and lateral tongue thrust, when swallowing liquid, were significantly higher than swallowing solids. There was a smaller proportion of children in Group N with lower lip interposition when swallowing liquids. TMD or presence of signs and/or symptoms of TMD was not associated with an abnormal deglutition. Nevertheless, orofacial myofunctional alterations could be considered influencing factors on TMD, due to the high prevalence of abnormal deglutition pattern. In addition, the abnormal deglutition could be attributed to the malocclusion, mixed dentition phase and orofacial myofunctional characteristics.

    2015-12-01

    Temporomandibular joint disorders (TMD) constitutes of a group of diseases that functionally affect the masticatory system, including the muscles of mastication and temporomandibular joint (TMJ). A number of etiologies with specific treatment have been identified, including the transcutaneous electrical nerve stimulation (TENS). The current paper presents a literature review on the use of TENS in the management of TMD patients. Temporomandibular joint disorder is very common disorder with approximately 75% of people showing some signs, while more than quarter (33%) having at least one symptom. An attempt to treat the pain should be made whenever possible. However, in cases with no defined etiology, starting with less intrusive and reversible techniques is prescribed. Transcutaneous electrical nerve stimulation is one such treatment modality, i.e. useful in the management of TMD. It comprises of controlled exposure of electrical current to the surface of skin, causing hyperactive muscles relaxation and decrease pain. Although the value of TENS to manage chronic pain in TMD patients is still controversial, its role in utilization for masticatory muscle pain is significant. However, an accurate diagnosis is essential to minimize its insufficient use. Well-controlled randomized trials are needed to determine the utilization of TENS in the management of TMD patients.

    The temporomandibular joint (TMJ) is a synovial joint essential for hinge and sliding movements of the mammalian jaw. Temporomandibular joint disorders (TMD) are dysregulations of the muscles or the TMJ in structure, function, and physiology, and result in pain, limited mandibular mobility, and TMJ noise and clicking. Although approximately 40-70% adults in the USA have at least one sign of TMD, the etiology of TMD remains largely unknown. Here, we highlight recent advances in our understanding of TMD in mouse models. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Nowadays, it is apparent that personality disorder is a common condition. Some of the concepts of personality disorder that are currently in use are flawed and need to be revised. The aim of this article is to discuss the controversy created by the uncertainties in the current classification system and to suggest ways forward. In particular, the clinician needs to be aware of the importance of assessing personality abnormality in terms of a severity dimension, and of the ways in which such an abnormality can impact on treatments for other conditions. These changes in the notion of personality disorder are needed as, for the first time, a good evidence base is being established for potential treatments and these will be maximized if we have a classification fit for therapeutic purpose.

    2011-02-01

    Temporomandibular disorder (TMD) is a collective term used to identify a group of musculoskeletal conditions of the temporomandibular region. Bruxism is a non-functional activity characterized by repeated tooth clenching or grinding in an unconscious manner. Over the time bruxism may lead to TMD by the uploading it causes. Nasal obstruction is a common complaint that necessitates mouth breathing when severe. The treatment of bruxism is frequently performed by oral appliances, which induce occlusal disengagement and relax jaw musculature and therefore reduce the force on the temporomandibular joint (TMJ). We believe that nasal obstruction may indirectly have a preemptive and therapeutic effect on sleep bruxism related TMD by causing mouth breathing. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Temporomandibular joint disorders are important oral health problems, reducing the quality of life of sufferers. It has been estimated that approximately 20% to 30% of the adult population will experience temporomandibular joint dysfunction. Arthrocentesis and lavage has been used to treat temporomandibular joint disorders for about 10 years, but the clinical effectiveness of the therapy has not been summarized in the form of a systematic review. To assess the effectiveness and complications of arthrocentesis and lavage for the treatment of temporomandibular joint disorders compared with controlled interventions. The Cochrane Oral Health Group's Trials Register (to August 2009), CENTRAL (The Cochrane Library 2009, Issue 3), MEDLINE (1950 to August 2009), EMBASE (1980 to August 2009), OpenSIGLE (to August 2009), CBMdisc (1981 to 2007 (in Chinese)) and Chinese Medical Library were searched. All the Chinese professional journals in the oral health field were handsearched and conference proceedings consulted. There was no language restriction. All randomised controlled trials (RCTs) (including quasi-randomised clinical trials) aiming to test the therapeutic effects of arthrocentesis and lavage for treating temporomandibular joint disorders. Two review authors independently extracted data, and three review authors independently assessed the risk of bias of included trials. The first authors of the selected articles were contacted for additional information. Two trials, at unclear to high risk of bias, were included in the review. The two trials, including 81 patients with temporomandibular joint disorders, compared arthrocentesis with arthroscopy. No statistically significant difference was found between the interventions in terms of pain. However, a statistically significant difference in favour of arthroscopy was found in maximum incisal opening (MIO) (weighted mean difference of -5.28 (95% confidence interval (CI) -7.10 to -3.46)).Mild and transient adverse reactions

    Mandibular asymmetries are the fulcrum of many debates among modern orthodontists and maxillofacial surgeons. The interest is even greater when facial asymmetries are correlated to the development of TMJ symptoms and temporomandibular disorders (TMD). The aim of this study is to investigate how mandibular asymmetries constitute etiological or predisposing factors for the development of temporomandibular disorders (TMD). We considered patients with mandibular asymmetries associated with TMD. Using orthodontic or surgical-orthodontic treatment, patients experienced correction of their TMJ symptoms. Thus, mandibular asymmetries represent a major risk factor for the development of TMD. We studied a sample of 16 subjects aged between 14 and 36-years-old (11 females and 5 males) with mandibular asymmetries (81% structural asymmetry, 19% functional asymmetry). These subjects presented skeletal and dental malocclusions combined with several temporomandibular disorders, mostly due to muscle tension. In 100% of cases, patients received orthodontic treatment. We compared pre- and post-treatment postero-anterior (PA) cephalometric analyses in order to evaluate asymmetry resolution. Comparison of measurements from pre- and post-therapy PA cephalograms showed resolution of mandibular asymmetries after treatment. The treatment resolved mandibular asymmetries and completely eliminated temporomandibular symptoms. Orthodontic treatment of patients presenting mandibular asymmetry enables correction of all TMJ symptoms and TMD. Mandibular symmetries can therefore be considered to constitute etiological or predisposing factors for the development of TMD. Copyright © 2014 CEO. Published by Elsevier Masson SAS.

    Temporomandibular disorders (TMD) refer to a group of clinical picture affecting the masticatory muscles and temporomandibular joint that are characterized by muscular or joint pain, dysfunction (limited or altered functions) and joint noises, as well as other associated symptoms, such as tension headaches, otalgia, dizziness, tinnitus, and others. Fibromyalgia (FM) is a syndrome of unknown etiology involving generalized chronic pain accompanied, in a high percentage of cases, by other symptoms such as asthenia, anxiety, depression, sleep disturbances, and other less frequent symptoms, such as temporomandibular disorders (TMD). Data were compiled by two experienced examiners following a specific form. An electronic search was carried out in the Cochrane Central Register of Controlled Trials (CENTRAL), PUBMED, and SCOPUS electronic databases (up to April 2016, unrestricted by date or language). Comparative clinical studies with patients with both clinical pictures involving the study of pathogenic processes. Fibromyalgia and temporomandibular disorders with muscle pain both have profiles that affect the muscular system and therefore share many epidemiological, clinical, and physiopathological symptoms. Because of this, we are led to think that there is, if not a common etiology, at least a common pathogenesis. This article revises the physiopathological processes of both clinical pictures in an attempt to determine their similarities and likenesses. This would undoubtedly help in providing a better therapeutic approach.

    The aim of this study was to evaluate stress distributions in the temporomandibular joints (TMJs) with temporomandibular disorders (TMDs) for comparison with healthy TMJs. A model of mandible and normal TMJs was developed according to CT images. The interfaces between the discs and the articular cartilages were treated as contact elements. Nonlinear cable elements were used to simulate disc attachments. Based on this model, seven models of various TMDs were established. The maximum stresses of the discs with anterior, posterior, medial and lateral disc displacement (ADD, PDD, MDD and LDD) were 12.09, 9.33, 10.71 and 6.07 times magnitude of the identically normal disc, respectively. The maximum stresses of the posterior articular eminences in ADD, PDD, MDD, LDD, relaxation of posterior attachments and disc perforation models were 21, 59, 46, 21, 13 and 15 times greater than the normal model, respectively. TMDs could cause increased stresses in the discs and posterior articular eminences.

    To establish the skeletal pattern in subjects with malocclusions and temporomandibular disorders (TMD); to assess the relationship between craniofacial skeletal structures and TMD in subjects with malocclusions. Sixty-four subjects with malocclusions, over 18 years of age, were included in the study. Temporomandibular disorders were clinically assessed according to the Helkimo Anamnestic Index. Subjects underwent a lateral cephalogram. Subjects were grouped according to the sagittal skeletal pattern (ANB angle) into class I, II and III. Parametric Student tests with equal or unequal variations were used (variations were previously tested with Levene test). Twenty-four patients with TMD (experimental sample); 40 patients without TMD (control group); interincisal angle was higher in class I and II (p < 0.05) experimental subjects; overjet was larger in experimental subjects; midline shift and Wits appraisal were broader in the experimental group in all three classes. In class III subjects, the SNB angle was higher in the experimental group (p = 0.01). Joint noises followed by reduced mandible mobility, muscular pain and temporomandibular joint (TMJ) pain were the most frequent symptoms in subjects with TMD and malocclusions. Temporomandibular joint status is an important factor to consider when planning orthodontic treatment in patients with severe malocclusions; midline shift, large overjet and deep overbite have been associated with signs and symptoms of TMD.

    Full Text Available Psychoneuroimmunology characterizes a disease entity that combines psychological components, central nervous system regulation, and immunology, to explain the etiological complexity of a disease. Temporomandibular disorders (TMDs include a heterogeneous group of painful conditions that involve the temporomandibular joint (TMJ, muscles of mastication, and the adjacent anatomic structures. This review focuses on the psychoneuroimmunological diseases and disorders that mimic the symptoms of TMDs. The differentiation of these disorders is of great significance to the oral physician - differentiating and diagnosing the cause of TMJ pain and treating it effectively to benefit the patient.The literature for this review was taken from Medline/PubMed, other indexed journals, standard text books, and online material.

    2015-03-01

    Full Text Available Temporomandibular disorders (TMD constitute a group of clinical problems involving the masticatory muscles, the temporomandibular joint and associated structures. An etiological connection of TMD with psychological factors was proposed as early as the 1980’s. Indeed, the interdependence of psychological and health aspects in the patient’s treatment, place light upon the more important variables contributing to the various mental disorders that may accompany TMD. Current literature suggests a close relationship between TMD and selected psychological factors, such as personality traits, stress, depression, anxiety, and catastrophizing. Of note, anxiety-depressive disorders, somatisation and catastrophizing contribute to chronic TMD, mainly in the form of myofascial pain. Hence, knowledge of the influence of psychological factors affecting TMD, enables the identification of patients with an increased risk of chronic painful TMD.

    2017-04-01

    Temporomandibular disorder (TMD) involves dysfunction of the temporomandibular joint and associated muscles of mastication causing pain with chewing, limitation of jaw movement, and pain. While the exact pathophysiology of TMD is not completely understood, it is thought that hyperfunction of the muscles of mastication places stress on the temporomandibular joint, leading to degeneration of the joint and associated symptoms. We hypothesize that chemodenervation of the muscles of mastication with IncobotulinumtoxinA (Xeomin) will decrease the stress on the temporomandibular joint and improve pain associated with temporomandibular joint and muscle disorder (TMJD). Twenty patients were randomized to IncobotulinumtoxinA (170 units) or saline injection of the masticatory muscles. Patient-reported pain scale (0-10) was recorded at 4-week intervals following injection for 16 weeks. Patients who received saline injection initially were assessed for reduction in pain at the first 4-week interval and if still had significant pain were rolled over into the IncobotulinumtoxinA arm. Preinjection pain scores were similar between patients. While there was a statistically significant reduction in pain score in the placebo group one month, there was an overall larger drop in average pain scores in those patients injected with IncobotulinumtoxinA initially. All patients initially injected with placebo crossed over into the IncobotulinumtoxinA group. Similar results were seen when examining the composite masticatory muscle tenderness scores. There was no significant change in usage of pain medication. We demonstrate utility of IncobotulinumtoxinA in treating patients with TMD with pain despite pain medication usage and other conventional treatments.

    2015-01-01

    Fibromyalgia syndrome (FMS) is a chronic painful syndrome and the coexistence of a painful condition caused by Temporomandibular Disorders (TMD) and FMS has been frequently raised for several studies, however, more likely hypothesis is that a set of FMS characteristics may lead to the onset of TMD symptoms and they are not merely coexisting conditions. Therefore, our aim is presenting a review of literature about the relation between fibromyalgia and the signs and symptoms of temporomandibular disorders. For this purpose, a bibliographic search was performed of the period of 1990-2013, in the Medline, Pubmed, Lilacs and Scielo databases, using the keywords fibromyalgia, temporomandibular disorders and facial pain. Here we present a set of findings in the literature showing that fibromyalgia can lead to TMD symptoms. These studies demonstrated greater involvement of the stomatognathic system in FMS and myogenic disorders of masticatory system are the most commonly found in those patients. FMS appears to have a series of characteristics that constitute predisposing and triggering factors for TMD. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

    To identify temporomandibular disorders (TMD) symptoms in two groups of fibromyalgia patients according to the temporal relation between the onset of facial pain (FP) and generalized body pain (GBP). CROSS-SECTIONAL STUDY DESIGN: Fifty-three consecutive women with fibromyalgia and FP were stratified according to the onset of orofacial pain: Group-A (mean age 47.30 ± 14.20 years old), onset of FP preceded GBP; Group-B (mean age 51.33 ± 11.03 years old), the FP started concomitant or after GBP. Research Diagnostic Criteria for Temporomandibular Disorders and the Visual Analogue Scale. Myofascial pain with mouth opening limitation (p = 0.038); right disc displacement with reduction (p = 0.012) and jaw stiffness (p = 0.004) were predominant in Group A. Myofascial pain without mouth opening limitation (p = 0.038) and numbness/burning were more common in Group B. All patients had temporomandibular joint symptoms, mainly muscle disorders. The prevalence of myofascial pain with limited mouth opening and right TMJ disc displacement with reduction were higher in Group A.

    Oral disorders have a psycho-social impact on the quality of life, that can be measured with instruments as the Oral Health Impact Profile questionnaire (OHIP). Using the OHIP, we evaluated if and how the orofacial pain can affect the quality of life in temporomandibular disorders (TMD) patients. A transversal case-control study was carried out. Study subjects were patients referred to the Section of Prosthetic Dentistry and Temporomandibular Disorders of the University of Pavia (Italy). Subjects were recruited sequentially until the target of 124. The controls were 61 "pain free" subjects, who were recruited from the same clinic. In analyzing the data, the chi squared test was used for categorical data, and t test and one-way analysis of variance were used for numerical scores. The subjects in this study were predominantly females (83.9%). The mean age of subjects was 35.1 years (standard deviation= 14.0). The most frequently reported symptoms were pain in the temporomandibular joint (TMJ) (87.1%). The data showed that orofacial pain had an important impact on daily life (pquality of life of TMD patients.

    2009-01-01

    Objective The purpose of this article is to offer a narrative review and discuss the possible relationship between temporomandibular disorders (TMDs) and whiplash injuries. Methods Databases from 1966 to present were searched including PubMed; Manual, Alternative, and Natural Therapy Index System; and Cumulative Index for Nursing and Allied Health Literature. Search terms used included whiplash injury, temporomandibular disorders and craniomandibular disorders. Inclusion criteria consisted of studies on orofacial pain of a musculoskeletal origin addressing the following topics: posttraumatic temporomandibular disorder (pTMD) incidence and prevalence, mechanism of injury, clinical findings and characteristics, prognosis (including psychologic factors). Excluded were studies of orofacial pain from nontraumatic origin, as well as nonmusculoskeletal causes including neurologic, vascular, neoplastic, or infectious disease. Results Thirty-two studies describing the effects of whiplash on TMD were reviewed based on inclusion/exclusion criteria. The best evidence from prospective studies indicates a low to moderate incidence and prevalence. Only 3 studies addressed mechanism of injury theories. Most studies focusing on clinical findings and characteristics suggest significant differences when comparing pTMD to idiopathic/nontraumatic patients. Regarding prognosis, most studies suggest a significant difference when comparing pTMD to idiopathic/nontraumatic TMD patients, with pTMD having a poorer prognosis. Conclusions There is conflicting evidence regarding the effects of whiplash on the development of TMD. Furthermore, because of lack of homogeneity in the study populations and lack of standardization of data collection procedures and outcomes measured, this review cannot conclusively resolve the controversies that exist concerning this relationship. This review of the literature is provided to clarify the issues and to provide useful clinical information for health care

    Approximately 6 to 16% of patients with trigeminal neuralgia symptoms present intracranial tumors, the most common being the vestibular schwannoma (acoustic neuroma). Some symptoms reported by patients include hearing loss, tinnitus, headaches, vertigo and trigeminal disturbances. An increased muscle response in the surrounding head and neck musculature may also be observed, which mimics signs and symptoms of temporomandibular disorders. In these cases, magnetic resonance imaging (MRI) has proved to be a useful tool in tumor diagnosis. The differential diagnosis between myofascial and neuralgic pain is important, as both may present similar characteristics, while being of different origin, and demanding special treatment approaches. The purpose of this paper is to demonstrate the relationship among trigeminal neuralgia symptoms, intracranial tumors and temporomandibular dysfunction by presenting a clinical case. PMID:19089251

    Psoriasis is a chronic, remitting and relapsing inflammatory disorder, involving the skin, nails, scalp and mucous membranes, that impairs patients' quality of life to varying degrees. Psoriatic arthritis is a chronic seronegative, inflammatory arthritis, usually preceded by psoriasis. Temporomandibular disorders is a generic term referred to clinical conditions involving the jaw muscles and temporomandibular joint. The aim of this study was to assess symptoms and signs of temporomandibular disorders in psoriasis patients with and without psoriatic arthritis. The study group included 112 patients (56 men, 56 women; median age 49.7±12 years) with psoriasis, 25 of them were affected by psoriatic arthritis. A group of 112 subjects without psoriasis (56 men, 56 women; median age 47.7±17 years) served as controls. Signs and symptoms of temporomandibular disorders were evaluated according to the standardized Research Diagnostic Criteria for Temporomandibular Disorders. Psoriasis patients were subgrouped according to the presence/absence of psoriatic arthritis and by gender, to assess the prevalence of traditional symptoms and signs of temporomandibular disorders. Patients with psoriasis, and to an even greater extent those with psoriatic arthritis, were more frequently affected by symptoms and signs of temporomandibular disorders, including an internal temporomandibular joint opening derangement than healthy subjects. A statistically significant increase in symptoms of temporomandibular disorders, in opening derangement, bruxism and sounds of temporomandibular joint was found in patients with psoriatic arthritis as compared with psoriasis patients without arthritis and controls. psoriasis seems to play a role in temporomandibular joint disorders, causing an increase in orofacial pain and an altered chewing function.

Signs and symptoms of temporomandibular disorders were evaluated according to the standardized Research Diagnostic Criteria for Temporomandibular Disorders. Psoriasis patients were subgrouped according to the presence/absence of psoriatic arthritis and by gender, to assess the prevalence of traditional symptoms and signs of temporomandibular disorders. RESULTS: Patients with psoriasis, and to an even greater extent those with psoriatic arthritis, were more frequently affected by symptoms and signs of temporomandibular disorders, including an internal temporomandibular joint opening derangement than healthy subjects. A statistically significant increase in symptoms of temporomandibular disorders, in opening derangement, bruxism and sounds of temporomandibular joint was found in patients with psoriatic arthritis as compared with psoriasis patients without arthritis and controls. CONCLUSIONS: psoriasis seems to play a role in temporomandibular joint disorders, causing an increase in orofacial pain and an altered chewing function. PMID:26019683

    2013-01-01

    Temporomandibular disorders (TMD) are common. Usual symptoms are joint noises and pain, pain in masticatory muscles, difficulties in jaw movements and headache. Treatment of TMD includes information on the background and good response to treatment of these disorders. The patient is advised on self-care routines, including relaxing the lower jaw, massaging the masticatory muscles and hot or cold packs on painful sites. Pharmacotherapy consists of paracetamol or anti-inflammatory analgesics. Occlusal appliances, physiotherapy, cognitive therapies and acupuncture are recommended. Complicated cases not responding to treatment are referred to specialized care.

    The relationship between handicaps because of voice disorders and temporomandibular disorders (TMDs) severity was examined. Fifty-two Persian women with temporomandibular disorder (TMD) were examined by two dentists in separate sessions and the assessment protocol of the Dentistry Clinic of Tehran University of Medical Sciences was filled by both dentists and finally they gave their opinion separately about the existence of TMD and categorized the severity of TMD as mild, moderate, and severe. To assess perceived disability resulting from voice disorders in TMD patients, the voice handicap index (VHI) questionnaire was used. The total score of VHI in 80.8% of patients with TMD was equal to or more than 14.5. A significant positive relationship was found between the severity of TMD and the total score of VHI (P = 0.000, r = 0.79). It seems that a comprehensive voice assessment should be included in the evaluation of TMD, and considering different effects of voice disorders on patients' lives, a complete voice evaluation including voice-related disability is necessary to understand the nature of pathophysiology of TMD.

    Full Text Available Abstract Background Temporomandibular disorders (TMDs are by far the most predominant condition affecting the temporomandibular joint (TMJ, however many patients have mild self-limiting symptoms and should not be referred for specialist care. The aim of this pilot study was to develop a simple, cost-effective management programme for TMDs using CD-ROM. 41 patients (age 18–70 participated in this study, patients were divided into three groups: the 1st group were involved in an attention placebo CD-ROM (contain anatomical information about the temporomandibular system, the 2nd group received information on CD-ROM designed to increase their control and self efficacy, while the 3rd group received the same programme of the 2nd group added to it an introduction to self-relaxing techniques followed by audio tape of progressive muscle relaxation exercises. Each of the groups was asked to complete a number of questionnaires on the day of initial consultation and six weeks afterwards. Results The two experimental groups (2nd & 3rd were equally effective in reducing pain, disability and distress, and both were more effective than the attention placebo group (1st, however the experimental groups appeared to have improved at follow-up relative to the placebo-group in terms of disability, pain and depressed mood. Conclusion This pilot study demonstrates the feasibility and acceptability of the design. A full, randomized, controlled trial is required to confirm the efficacy of the interventions developed here.

    The aim of this study was to determine the prevalence of temporomandibular disorder (TMD) signs in a group of institutionalized patients with schizophrenia. Three hundred thirty-nine patients with schizophrenia were examined and compared with 107 age-matched and gender-matched control subjects. TMD signs were evaluated according to the Research Diagnostic Criteria to assess temporomandibular joint pain to palpation, limitation of maximum mouth opening, alteration of mouth opening pathway (deviation/deflection) and temporomandibular joint noises. In addition, tooth wear was recorded for the assessment of bruxism. The prevalence of any TMD signs was observed higher (P = 0.001) in the patients with schizophrenia (284/339, 83.7%) than in the controls (72/107, 67.3%). The prevalence of more than one TMD sign was also significantly higher (P = 0.03) in the patients with schizophrenia (131/339, 38.6%) than in the controls (29/107, 27.1%). Significant differences between the two groups were apparent for joint pain on palpation (P = 0.006), deflection (P = 0.006) and joint sounds (P = 0.002). Severe tooth wear was evident in 39.2% of the patients with schizophrenia compared with 21.2% in the control group (P = 0.001). The finding of the present study showed that, compared to control population, chronically hospitalized patients with schizophrenia seem to be more prone to the development of TMD signs and severe tooth wear and bruxism.

Two hundred volunteers aged 19.3 to 27.8 (mean 21.50, SD 0.97 participated in this study. An analogue pressure algometer was used for the evaluation of muscle tenderness of the following masticatory muscles: superficial and deep parts of the masseter muscle; anterior and posterior parts of the temporal muscle; and the tissues adjacent to the lateral and dorsal part of the temporomandibular joint capsule. Each patient described the algometry result for the individual components of the masticatory motor system, by selecting each time the intensity of pain on a 100 mm Visual Analogue Scale (VAS ruler. The area under the receiver operating characteristic (ROC curve, indicating the discriminatory efficiency for asymptomatic subjects and patients with temporomandibular dysfunction according to the dysfunction Di index, was the largest for the mean pain value (AUC = 0.8572; SEM = 0.0531. The 7.4 VAS cut-off point marked 95.3% specificity for this variable in identifying healthy subjects and 58.4% sensitivity in identifying patients with symptoms of dysfunctions (accuracy 68.1%. Assuming comparable sensitivity (74.9% and specificity (74.2% for a diagnostic test, there was test accuracy of 74.5% at the 4.2 VAS cut-off point.

    Temporomandibular joint disorders (TMD) are often associated with aural manifestations. However, it is not clear whether aural fullness could be induced by TMD. The purpose was to investigate the TMD and effectiveness of TMD treatments in patients with mainly or exclusively aural fullness complaint. One hundred and twelve patients, who had aural fullness as the main or sole complaint, presented to the Otolaryngology Department, PLA Army General Hospital, Beijing, China, between January 2010 and January 2015. Patients' medical history indicated that they had previously been diagnosed and treated for otitis media or sensorineural hearing loss but without positive results. Patients were subjected to pure tone audiometry and acoustic immittance screening using GSI-61 clinical audiometer and GSI TympStar middle ear analyzer respectively. Patients were examined by questionnaire, X-ray and/or computed tomography scan of temporomandibular joint. TMD was categorized according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Patients were then treated for TMD. All the patients showed normal eardrum and type A tympanogram. The patients of 60.7% (68/112) were classified as group I TMD disorders (muscle disorders), 34.8% (39/112) were group II (disc displacements), and 4.5% (5/112) were group III (arthralgia, osteoarthritis, and osteoarthrosis). Aural fullness was completely resolved or significantly improved in 67 and 34 patients respectively following treatments aimed at improving TMD, with a combined effectiveness of 90.2% (101/112). TMD treatments are especially effective (94.1%) in group I TMD. TMD as a potential cause of aural fullness should be considered in otolaryngology practice.

    Metastatic lesions make up approximately 1% of all oral cancers.A comparatively rare location is the temporomandibular joint.Leading symptoms can be misdirecting, especially in the beginning,because they are frequently similar or even identical to those occurring in temporomandibular disorders. Therefore it can be quite difficult to confirm the diagnosis of a TMJ metastasis.delayed initiation of therapy and thus a poor prognosis are often the results. A review of the literature from 1954 to 2013 was realized and the published cases between 1954 and January 2013 were evaluated.The results were analyzed according to gender distribution, age,first symptoms, location of the primary tumor, as well as to the occurrence of malignancies in the patients' medical history. The research identified sixty-six patients. Tumors of the lung and breast were the main starting points of the metastatic spread. The histopathological workup showed above all the diagnosis of an adenocarcinoma. In all of the cases, unspecific symptoms led to the diagnosis of a metastatic disease. In the case of nonspecific TMJ affection, diagnostics should consider less-frequent diagnoses, such as the presence of metastasis.A clinical differentiation by additional symptoms like swelling, unexplained weight loss and night sweats, as well as a tumor disease in the past or failure of conservative treatment can provide additional indications. If there is reasonable suspicion,extended medical imaging and diagnostic measures must be performed to allow early treatment initiation and a better prognosis.

    There is a need to expand the current temporomandibular disorders' (TMDs) classification to include less common but clinically important disorders. The immediate aim was to develop a consensus-based classification system and associated diagnostic criteria that have clinical and research utility for less common TMDs. The long-term aim was to establish a foundation, vis-à-vis this classification system, that will stimulate data collection, validity testing and further criteria refinement. A working group [members of the International RDC/TMD Consortium Network of the International Association for Dental Research (IADR), members of the Orofacial Pain Special Interest Group (SIG) of the International Association for the Study of Pain (IASP), and members from other professional societies] reviewed disorders for inclusion based on clinical significance, the availability of plausible diagnostic criteria and the ability to operationalise and study the criteria. The disorders were derived from the literature when possible and based on expert opinion as necessary. The expanded TMDs taxonomy was presented for feedback at international meetings. Of 56 disorders considered, 37 were included in the expanded taxonomy and were placed into the following four categories: temporomandibular joint disorders, masticatory muscle disorders, headache disorders and disorders affecting associated structures. Those excluded were extremely uncommon, lacking operationalised diagnostic criteria, not clearly related to TMDs, or not sufficiently distinct from disorders already included within the taxonomy. The expanded TMDs taxonomy offers an integrated approach to clinical diagnosis and provides a framework for further research to operationalise and test the proposed taxonomy and diagnostic criteria. © 2014 John Wiley & Sons Ltd.

    Full Text Available Objective: To verify the prevalence of signs and symptoms of temporomandibular disorder and their association with joint noise, joint hypermobility, occlusal interference, orthodontic treatment and bruxism in a specific population composed of young university students. Methods: One hundred and seventeen (117 volunteers (mean age of 22 years were selected from the undergraduate course in Dentistry at the School of Dentistry of the “Centro Universitário Hermínio Ometto” (Araras, São Paulo, Brazil. The volunteers answered a questionnaire and were submitted to clinical and electrovibratography exams. Afterwards, the volunteers were classified as either having temporomandibular disorder or not, considering the presence of painful sensitivity in the temporomandibular joint and/or presence of joint noise. The prevalenceof the studied factors was calculated together with the association between each factor, and the presence of temporomandibular disorderwas analyzed by the Chi-square test. Results: The prevalence of temporomandibular disorder in the evaluated sample was 42.9% and significant association was found between temporomandibular disorder and joint noise (p<0.05; and between temporomandibular disorder and bruxism (p<0.05. Conclusion: The results suggest that patients with presence of precisely diagnosed bruxism and joint noise should be monitored with regard to the appearance of signs and symptoms of temporomandibular disorder.

    To investigate the efficacy of temporomandibular joint (TMJ) lavage (arthrocentesis or arthroscopy) for the treatment of temporomandibular disorders in reducing pain and improving jaw motion. We performed a systematic review of the literature and meta-analysis of randomized controlled trials (RCTs) comparing TMJ lavage with conservative measures. The data sources were MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), Scopus, Web of Science, and reference lists of relevant articles. Two independent reviewers identified RCTs by using controlled vocabulary (MeSH, Emtree) and free text terms. Data extracted from the selected studies included population characteristics, interventions, outcomes, and funding sources. Risk of bias was assessed with the Cochrane Collaboration risk assessment tool for RCTs. Five studies met the inclusion criteria, for a total of 308 patients. Of these studies, 3 were categorized as having a high risk of bias and 2 had a low risk. The summary effect of the 5 studies showed a reduction in pain in the intervention group at 6 months (-0.63; 95% confidence interval [CI], -0.90 to -0.37; P < .00001; I2 = 88%) and 3 months (-0.47; 95% CI, -0.75 to -0.19; P = .001; I2 = 85%). This was not the case at 1 month. No difference in mouth opening was observed at 6 months (-0.21; 95% CI, -1.82 to 1.40; P < .80; I2 = 74%), 3 months (0.20; 95% CI, -1.81 to 2.20; P = .85; I2 = 68%), and 1 month (-1.18; 95% CI, -2.90 to 0.55; P = .18; I2 = 0%). Given the relatively small number of patients included in this meta-analysis, the high risk of bias in 3 studies, and the statistical and clinical heterogeneity of the included studies, the use of TMJ lavage for the treatment of temporomandibular disorders should be recommended with caution because of the lack of strong evidence to support its use.

    We conducted a clinical cross-sectional study to evaluate the association between obesity and the presence of painful temporomandibular disorders (TMD), controlling for age, gender, presence of migraine, depression, non-specific somatic symptoms and obstructive sleep apnoea syndrome (OSAS) in an adult population. A total of 299 individuals (76·6% women) with a mean age of 36·8 ± 12·8 years were evaluated. TMD were classified using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Depression and non-specific somatic symptoms were scored by the Symptom Checklist-90, while pain and disability was rated by the Graded Chronic Pain Scale. Bioimpedanciometry (BIA) was used to assess obesity through total body fat percentage. Migraine was diagnosed according to the criteria of the International Classification of Headache Disorders-2 (ICHD-2). OSAS was classified according to the Berlin Questionnaire. We performed univariate and multivariate models, chi-square tests and odds ratios (OR) with 95% confidence intervals (CI). In the single regression analysis, TMD-pain was significantly associated with total body fat percentage (P = 0·01). In the multivariate analysis, migraine, age, non-specific somatic symptoms and OSAS showed to be stronger predictors of TMD-pain, and obesity did not retain in the regression model. The initial association found between obesity and TMD-pain is lost when it was corrected for gender, migraine, non-specific somatic symptoms and OSAS. © 2016 John Wiley & Sons Ltd.

    Disc and condylar position were observed on MRIs of temporomandibular joint disorder patients and condylar position agreement between MRI and tranascranal radiography was evaluated. MRI and transcranial radiographs of both TM joints from 67 patients with temporomandibular disorder were used. On MRI, the position and shape of disc and condylar position as anterior, middle, posterior was evaluated at medial, center, and lateral views. On transcranial radiographs, condylar position was evaluated using the shortest distance from condyle to fossa in anterior, superior, and posterior directions. 1. On MRI, 96 joints (71.6%) of 134 had anterior disc dispalcement with reduction and 38 joints (28.4%) without reduction. 2. Fourteen (14.6%) of 96 reducible joints showed anterior condylar position. 19 (19.8%) showed central position, 63 joints (65.6%) showed posterior position. Two joints (5.3%) of 38 non-reducible joints showed anterior condylar position, while 9 (23.7%) showed central position, and 27 (71.1%)-posterior position. 3. In 85 joints (63.4%) of 134, the transcranial condylar position agreed with that of the central MRI view, 10 joints (7.5%) with that of medial, 16 joints (11.6%) with that of lateral, and 23 joints (17.2%) disagreed with that of MRI. On MRI, most of the reducible and non-reducible joints showed posterior condylar position. Transcranial radiographs taken with machine designed for TMJ had better agreement of condylar position with that of MRI. Extremely narrow joint spaces or very posterior condylar positions observed on transcranial radiographs had a little more than fifty percent agreement with those of MRIs.

    The purpose of this study was to prove the relationship between arthrographic and clinical features in temporomandibular joint disorders. In order to carry out this study, ninety-eight arthrographic examinations of temporomandibular joints were performed in eighty-two patients who had the temporomandibular joint disorders. As the arthrographic examination, the cases were classified in three groups, disk displacement with reduction, disk displacement without reduction, within normal limit. After this, the cases were clinically examined, and the results were compared and analyzed in each other group. The obtained results were as follows: 1. As the classification by arthrographic examination, three groups (disc displacement with reduction, disc displacement without reduction, within normal limit) were 41%, 54%, 5% of total cases in this study, respectively. 2. The third decade (65%) was most frequent in this study. The average age of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 24, 28, 21, and disc displacement without reduction group was higher than any other group. 3. In the chief complaint, pain was the most frequent in all three groups. Joint sound was also frequent in disc displacement with reduction group, but in disc displacement without reduction group, limitation of mouth opening was more frequent. 4. Of the various pain, the movement pain was most frequent (61%) in this study. In joint sound, click (63%) was the most frequent in disc displacement with reduction group, but sound history (42%) and no sound (31%) were more frequent in disc displacement without reduction group. 5. The average maximum opening of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 44 mm, 32.9 mm, 44 mm, and disc displacement without reduction group was less than any other group. 6. The masticatory disturbance of each group (disc displacement with reduction, disc

    We investigated the correlation between the antioxidant capacity of synovial fluid and radiological findings of intra-articular structures in patients with disorders of the temporomandibular joint (TMJ). We recruited 21 patients (9 men and 12 women, aged 18-84 years of age) with such disorders, excluding myofascial pain and dysfunction syndrome, or other muscular disorders. The clinical variables recorded included age, sex, interincisal distance, and visual analogue pain scores (VAS). Radiological findings were obtained from diagnostic arthrogram and cone-beam computed tomography (CT). The antioxidant capacity of the synovial fluid was measured by chemiluminescence. Eleven patients were radiologically diagnosed with closed lock, and the remaining 10 with no closed lock. An anchored intra-articular disc was most often seen on cone-beam CT (n=19) followed by perforated disc (n=7), osteoarthrosis (n=7), and anterior disc displacement without reduction (n=5). Although there were no significant differences between antioxidant capacity and age, sex, VAS, or any findings on cone-beam CT, antioxidant capacity was significantly decreased in the patients with closed lock compared with those who did not have closed lock (p=0.02). The results suggest an association between the oxidative stress of the synovial fluid and closed-lock in disorders of the TMJ.

    This study was performed to evaluate the relationship between pterygoid plate asymmetry and temporomandibular joint disorders. Cone-beam computed tomography (CBCT) images of 60 patients with temporomandibular disorders (TMD) involving pain were analyzed and compared with images of 60 age- and gender-matched controls. Three observers performed linear measurements of the lateral pterygoid plates. Statistically significant differences were found between measurements of the lateral pterygoid plates on the site that had pain and the contralateral site (p<0.05). The average length of the lateral pterygoid plates (LPPs) in patients with TMD was 17.01±3.64 mm on the right side and 16.21±3.51 mm on the left side, and in patients without TMD, it was 11.86±1.97 mm on the right side and 11.98±1.85 mm on the left side. Statistically significant differences in the LPP length, measured on CBCT, were found between patients with and without TMD (p<0.05). The inter-examiner reliability obtained in this study was very high for all the examiners (0.99, 95% confidence interval: 0.98-0.99). Within the limits of the present study, CBCT lateral pterygoid plate measurements at the side with TMD were found to be significantly different from those on the side without TMD. More research is needed to explore potential etiological correlations and implications for treatment.

    Aims We assessed and compared the diagnostic accuracy of two sets of diagnostic criteria for headache secondary to temporomandibular disorders (TMD). Methods In 373 headache subjects with TMD, a TMD headache reference standard was defined as: self-reported temple headache, consensus diagnosis of painful TMD and replication of the temple headache using TMD-based provocation tests. Revised diagnostic criteria for Headache attributed to TMD were selected using the RPART (recursive partitioning and regression trees) procedure, and refined in half of the data set. Using the remaining half of the data, the diagnostic accuracy of the revised criteria was compared to that of the International Headache Society's International Classification of Headache Diseases (ICHD)-II criteria A to C for Headache or facial pain attributed to temporomandibular joint (TMJ) disorder. Results Relative to the TMD headache reference standard, ICHD-II criteria showed sensitivity of 84% and specificity of 33%. The revised criteria for Headache attributed to TMD had sensitivity of 89% with improved specificity of 87% (p muscle palpation or jaw movement. Conclusion Having significantly better specificity than the ICHD-II criteria A to C, the revised criteria are recommended to diagnose headache secondary to TMD. PMID:22767961

    This study investigated the prevalence of Temporomandibular Disorders (TMD) in the elderly and its association with palpation of the temporomandibular joint (TMJ), masticatory and cervical muscles as well as the presence of headache and joint noises. The sample consisted of 200 elderly of both genders (mean age: 69.2±5.7 years). The clinical evaluation of TMD signs and symptoms was divided into three stages: an anamnestic questionnaire, a TMJ evaluation, and a muscular examination. The results were analyzed through descriptive statistics as well as using χ2 and the tendency tests. The presence of TMD was observed in 61% of the sample (mild: 43.5%, moderate: 13%, severe: 4.5%). A significantly greater prevalence of TMD was found for females (72.4%) compared with that for men (41.1%) (ppalpation of the TMJ (p=0.0168), of masticatory muscles (pmuscles (pTMJ palpation was not significant. The elderly presented high TMD prevalence, mostly in females, with mild severity and related to TMJ and masticatory/cervical muscles palpation. Thus, the accomplishment of a detailed clinical examination to investigate the presence of such disorders is essential and it must not be neglected during the treatment of elderly patients.

    Full Text Available Sleep Bruxism is a significant etiology of temporomandibular disorder (TMD and causes many dental or oral problems such as tooth wear or facet. There is no study analyzing the relationship between sleep bruxism and TMD. Objective: To investigate any relationship between occlusal grinding pattern during sleep bruxism and temporomandibular disorder. Methods: A cross-sectional study involving 30 sleep bruxism patients attended the Faculty Dentistry Universitas Indonesia Teaching Hospital (RSGMP FKG UI. Completion of 2 forms of ID-TMD index and questionnaire from American Academy of Sleep Medicine were done. BruxChecker was fabricated and used for two nights to record the occlusal grinding pattern. The occlusal grinding pattern was categorized into laterotrusive grinding (LG and mediotrusive side. Further divisons of LG were: incisor-canine (IC, incisor-caninepremolar (ICP and incisor-canine-premolar-molar (ICPM. Mediotrusive side was classified as mediotrusive contact (MC and mediotrusive grinding (MG. Results: It was found that occlusal grinding pattern in non-TMD subjects were IC+MC, in subjects with mild TMD were ICP+MG and in subjects with moderate TMD were ICP+MG and ICPM+MG. TMJ was more significantly affected by ICP and ICPM grinding pattern than that of IC. Conclusion: There was a significant relationship between occlusal grinding pattern during sleep bruxism and TMD.DOI: 10.14693/jdi.v20i2.149

    Full Text Available The present cross-sectional study was designed to investigate the association between sleep bruxism (SB, tinnitus and temporomandibular disorders (TMD. The sample consisted of 261 women (mean age of 37.0 years. The Research Diagnostic Criteria for Temporomandibular Disorders were used to classify TMD and self-reported tinnitus. SB was diagnosed by clinical criteria proposed by the American Academy of Sleep Medicine. The results showed an association between painful TMD and tinnitus (OR = 7.3; 95%CI = 3.50-15.39; p < 0.001. With regard to SB, the association was of lower magnitude (OR = 1.9; 95%CI = 1.16-3.26; p < 0.0163. When the sample was stratified by the presence of SB and painful TMD, only SB showed no association with tinnitus. The presence of painful TMD without SB was significantly associated with tinnitus (OR = 6.7; 95%CI = 2.64-17.22; p < 0.0001. The concomitant presence of painful TMD and SB was associated with a higher degree of tinnitus severity (OR = 7.0; 95%CI = 3.00-15.89; p < 0.0001. It may be concluded that there is an association between SB, painful TMD and self-reported tinnitus; however, no relationship of a causal nature could be established.

    Full Text Available Temporomandibular disorder (TMD is an umbrella term for a collection of disorders affecting the temporomandibular joint (TMJ and associated tissues. TMD is not a rare pathology for the dentist. The most common presenting symptom is pain, which causes the patient seek immediate treatment. Management is dictated by the cause. The most ′famed′ causes include trauma, inflammation, aging, parafunctional habits, infections, neoplasms, and stress; and these are always considered in the differential diagnosis of TMJ pain. There are some less ′famed′ causes of TMD, which are characterized by increased pain sensitivity due to psychosocial factors; these include myofascial pain syndrome and functional somatic syndromes (FSS such as fibromyalgia and chronic fatigue syndrome. They present with chronic pain, fatigue, disability, and impairment in ability to perform daily activities. A non-systematic search in the English literature revealed numerous studies describing the occurrence of TMD in these conditions, along with few other oral manifestations. TMD has been even considered to be a part of the FSS by some. In these patients, TMD remains a recurring problem, and adequate management cannot be achieved by traditional treatment protocols. Awareness of these conditions, with correct diagnosis and modification of management protocols accordingly, may resolve this problem.

    This study investigated the associations between magnetic resonance imaging (MRI) findings and pain in the temporomandibular joint (TMJ). The study included 646 TMJs of 323 consecutive patients with temporomandibular disorders; of these, 222 (34.4%) had TMJ pain whereas 424 (65.6%) had no TMJ pain. MRIs were used to evaluate disc position, osteoarthritis, joint fluid, and bone marrow edema. Internal derangement was classified as normal, anterior disc displacement with reduction, and anterior disc displacement without reduction (ADDWOR); condylar morphology was classified as normal, moderate bony change, and severe bony change. The odds ratio (OR) for each MRI variable for nonpainful versus painful TMJs was computed using logistic regression analysis. Compared with joints with normal disc position, the OR of those with ADDWOR was 2.74 (P pain. Similarly, compared with joints with normal condylar morphology, the OR of those with severe bony change was 4.62 (P = .02) for TMJ pain. In addition, the risk of TMJ pain increased by 2.37 in joints with joint fluid (P joints with bone marrow edema (P = .006). The risk of TMJ pain increased significantly with ADDWOR in combination with severe bony change, joint fluid, and bone marrow edema. These results suggest an association between TMJ pain and ADDWOR, severe bony change, joint fluid, and bone marrow edema. Thus, combining various MRI variables may improve the diagnostic accuracy of TMJ pain. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

    The aim of the present study was to compare cone-beam computerized tomography (CBCT) findings and joint space measurement in temporomandibular disorder (TMD) and non-TMD joints, and to correlate these findings with the clinical diagnosis. The study was conducted on patients diagnosed with temporomandibular joint (TMJ) osteoarthritis or closed lock according to the Research Diagnostic Criteria for TMDs (Group IIb, IIc, and III). CBCT and clinical records of non-TMD patients who sought treatment for purposes other than TMD were used retrospectively as a control. The following radiographic criteria were assessed: flattening, osteophyte, Ely's cyst, condylar surface irregularities, and joints' space measurements. Osteoarthritic joints had significantly more condylar irregularities (P50.0), osteophytes (P50.0), and condylar flattening (P50.003) than non-TMD joints. Osteoarthritic joints had significantlymore superior surface irregularities (P50.0) and osteophytes (P50.006) than closed lock joints.Non-TMDjoints had significantlymore joint space (5.64+1.88) compared with osteoarthritic joints (4.57+1.97), (P50.025). The correlation among TMD, osteophytes, and flattening of the condylar surface was statistically significant (r50.331, Pv0.000). Cone-beam computerized tomography findings are significantly associated with the clinical diagnosis of TMD. Osteophytes and flattening of the condylar surface are common features of TMD.

    Women are more likely to present temporomandibular disorders (TMD); however, studies comparing genders in Brazilian samples are rare. To analyze the proportion of men and women, as well as the association between gender and age, problem duration, and TMD symptoms in patients admitted to an university clinic for treatment. Interview and assessment data of protocols from 1,000 patients diagnosed with TMD were collected and analyzed and then divided into two groups, male (n = 177) and female (n = 823). The exploratory analysis was based on contingency tables and χ2 test was carried out. Subsequently, the logistic regression model was used and the odds ratios (OR) concerning the evaluated comparisons were calculated. Females were more prevalent in the sample, and mean ages and TMD duration were similar between the groups, with higher occurrence in young adults (19 to 40 years old). The OR values showed an association between the female gender and the signs/symptoms of pain in the temporomandibular joint, pain in the facial muscles, neck and shoulders, headache, fatigue in the muscles of mastication, otologic symptoms, and dysphonia. Women had two times higher chances of presenting these symptoms than men. In the sample of Brazilian patients with TMD, the number of women who presented a higher prevalence of painful symptoms was greater, followed by otologic symptoms and complaints of dysphonia. The prevalence of joint noise was similar in both studied groups.

    Recently, magnetic resonance imaging (MRI) is indispensable for the diagnosis of temporomandibular disorders (TMD). Motion Artifacts of MRI occur more frequently than in other conventional methods, because it takes a long time to obtain the images. This paper reported on Motion Artifacts on MRI. MRI studies of 232 temporomandibular joints were performed in 116 patients with TMD by using a 0.5-T magnetic resonance (MR) scanner, with spin echo sequence: protondensity-weighted. And we took MRI slices at opening phase and closing phase. So 232 slices were gathered and we evaluated clinically the incidence of Motion Artifacts, that is to say, double and multiple images and other factors. The 103 slices in 56 patients showed Motion Artifacts. There is no significant difference between sexes. By age group, those in their teens were most frequent, followed by those in their fifties, forties, thirties and twenties. Also the same results were obtained for double image and multiple image. Incidence of Motion Artifact was most frequent at the opening phase. There is no significant difference between double and multiple image. (author)

    Shaffer, Stephen M; Brismée, Jean-Michel; Sizer, Phillip S; Courtney, Carol A

    2014-01-01

    Temporomandibular disorders (TMD) are a heterogeneous group of diagnoses affecting the temporomandibular joint (TMJ) and surrounding tissues. A variety of methods for evaluating and managing TMD have been proposed within the physical therapy profession but these sources are not peer-reviewed and lack updates from scientific literature. The dental profession has provided peer-reviewed sources that lack thoroughness with respect to the neuromusculoskeletal techniques utilized by physical therapists. The subsequent void creates the need for a thorough, research informed, and peer-reviewed source regarding TMD evaluation and management for physical therapists. This paper is the first part in a two-part series that seeks to fill the current void by providing a brief but comprehensive outline for clinicians seeking to provide services for patients with TMD. Part one focuses on anatomy and pathology, arthro- and osteokinematics, epidemiology, history taking, and physical examination as they relate to TMD. An appreciation of the anatomical and mechanical features associated with the TMJ can serve as a foundation for understanding a patient’s clinical presentation. Performance of a thorough patient history and clinical examination can guide the clinician toward an improved diagnostic process. PMID:24976743

    Temporomandibular disorder (TMD) is a multifactorial disease. For this reason, it is difficult to obtain an accurate and correct diagnosis. In this context, conservative treatments, including therapeutic exercises classified as stretching, relaxation, coordination, strengthening and endurance, are oftentimes prescribed. Thus, the aim of the present article was to conduct a literature review concerning the types of exercises available and the efficacy for the treatment of muscular TMD. The review included researches carried out between 2000 and 2010, indexed on Web of Science, PubMed, LILACS and BBO. Moreover, the following keywords were used: Exercise, physical therapy, facial pain, myofascial pain syndrome, and temporomandibular joint dysfunction syndrome. Studies that did not consider the subject "TMD and exercises", used post-surgery exercises and did not use validated criteria for the diagnosis of TMD (RDC/TMD) were not included. The results comprised seven articles which proved therapeutic exercises to be effective for the treatment of muscular TMD. However, these studies are seen as limited, since therapeutic exercises were not applied alone, but in association with other conservative procedures. In addition, they present some drawbacks such as: Small samples, lack of control group and no detailed exercise description which should have included intensity, repetition, frequency and duration. Although therapeutic exercises are considered effective in the management of muscular TMD, the development of randomized clinical trials is necessary, since many existing studies are still based on the clinical experience of professionals.

    The objective of this study was to retrospectively analyze the incidence of the concurrent existence of temporomandibular disorders (TMD) and headaches. Forty patients (36 female, 4 male, mean age: 29.9±9.6 years) clinically diagnosed with TMD were screened. Patient records were analyzed regarding: range of mouth opening, temporomandibular joint (TMJ) noises, pain on palpation of the TMJ and masticatory muscles and neck and upper back muscles, and magnetic resonance imaging of the TMJ. According to patient records, a total of 40 (66.6%) patients were diagnosed with TMD among 60 patients with headache. Thirty-two (53%) patients had TMJ internal derangement (ID), 8 (13%) patients had only myofascial pain dysfunction (MPD) and 25 (41.6%) patients had concurrent TMJ ID/MPD. There were statistically significant relationships between the number of tender masseter muscles and MPD patients (p=0.04) and between the number of tender medial pterygoid muscles and patients with reducing disc displacement (RDD) (p=0.03). The TMJ and associated orofacial structures should be considered as possible triggering or perpetuating factors for headaches, especially tension-type. There might be a significant connection between TMD and headache. However, most medical and dental practitioners are unaware of this relationship. Therefore, a careful evaluation of the TMJ and associated orofacial structures is required for a correct interpretation of the craniofacial pain in headache patients, and these patients should be managed with a multidisciplinary approach.

La existencia de variados enfoques terapéuticos para los trastornos temporomandibulares queda justificada por la multifactorialidad de la etiología; las 2 alternativas más utilizadas son las férulas oclusales y el tallado selectivo. Se prefiere la fisioterapia a la quimioterapia, como coadyuvante terapéutica de los trastornos temporomandibulares, ya que disminuye el peligro de producir reacciones adversas. Solo se indicará el tratamiento quirúrgico cuando han fracasado los métodos conservadores.A literature review was made to provide updated information on the different therapeutic alternatives at the disposal of dental professionals for the treatment of termporomandibular disorders aimed at relieving pain and re-establish the functioning of the joint. However, it is necessary to firstly make a good diagnosis and then detect the causative factors, emphasizing that stress is a key element to be taken into consideration. The existence of various therapeutical approaches for temporomandibular disorders is due to the multiple factors present in the etiology; the two most used alternatives are occlusal splints and selective carving. Physiotherapy is prefered over chemotherapy, as therapeutic coadjuvant for temporomandibular disorders, because likely occurence of adverse reaction decreases. The surgical treatment will be advised only in the event of failure of standard methods.

    The aim of this study was to determine the association between more advanced stages of temporomandibular joint (TMJ) intra-articular disorders ("TMJ intra-articular status"), representing a transition from normal joint structure to TMJ disc displacement with and without reduction (DDwR and DDwoR) to degenerative joint disease (DJD), and patient-reported outcomes of jaw pain, function, and disability ("TMD impact"). This cross-sectional study included 614 cases from the RDC/TMD Validation Project with at least one temporomandibular disorder (TMD) diagnosis. TMJ intra-articular status was determined by 3 blinded, calibrated radiologists using magnetic resonance imaging and computed tomography as one of normal joint structure, DDwR, DDwoR, or DJD, representing the subject's most advanced TMJ diagnosis. TMD impact was conceptualized as a latent variable consisting of 1) pain intensity (Characteristic Pain Index from the Graded Chronic Pain Scale [GCPS]), 2) jaw function (Jaw Functional Limitation Scale), and 3) disability (Disability Points from GCPS). A structural equation model estimated the association of TMJ intra-articular status with the latent measure TMD impact as a correlation coefficient in all TMD cases (n = 614) and in cases with a TMD pain diagnosis (n = 500). The correlations between TMJ intra-articular status and TMD impact were 0.05 (95% confidence interval [CI], -0.04 to 0.13) for all TMD cases and 0.07 (95% CI, -0.04 to 0.17) for cases with a pain diagnosis, which are neither statistically significant nor clinically relevant. Conceptualizing worsening of TMJ intra-articular disorders as 4 stages and characterizing impact from TMD as a composite of jaw pain, function, and disability, this cross-sectional study found no clinically significant association. Models of TMJ intra-articular status other than ours (normal structure → DDwR → DDwoR → DJD) should be explored. © International & American Associations for Dental Research.

    The Eighth Scientific Meeting of The TMJ Association, Ltd. was held in Bethesda, Maryland, September 11-13, 2016. As in the past, the meeting was cosponsored by components of the National Institutes of Health with speakers invited to review the state of temporomandibular disorder science and propose recommendations to further progress. The theme of precision medicine, which aims to tailor disease treatment and prevention to match the characteristics of an individual patient (genetic, epigenetic, environmental, lifestyle) underscored the current consensus that temporomandibular disorders are no longer viewed as local conditions of jaw pain and dysfunction. Rather, they represent a complex family of biopsychosocial disorders that can progress to chronic pain, most often accompanied by one or more other chronic pain conditions. Temporomandibular disorders and these comorbidities, called chronic overlapping pain conditions, predominantly or exclusively affect women in their childbearing years and reflect central nervous system sensitization. Presenters at the meeting included leaders in temporomandibular disorder and pain research, temporomandibular disorder patients and advocates, and experts in other fields or in the use of technologies that could facilitate the development of precision medicine approaches in temporomandibular disorders.

    Full Text Available Temporomandibular disorder (TMD is ranked the second leading cause of orofacial pain after toothache, and there is no effective standard treatment for all cases. Therefore, much research has been conducted in the therapeutic areas of TMD, such as acupuncture and electrotherapy, for this purpose. The aim of this research was to evaluate application of the neuromagnetic stimulator device Haihua model CD-9, used within the precepts of acupuncture in treating TMD-related pain symptoms and limited mouth opening. Analysis and discussion of this study were based on pain intensity index and range of mouth-opening evaluation before and after each session. Nine patients diagnosed with muscle TMD, referred by the surgery sector of Center Dental Specialties (CEO – I in Piracicaba-São Paulo participated in this research. Considering the simplicity of the technique and good results obtained, use of this device is suggested as an additional therapeutic tool for relief of TMD symptoms.

    Patients with temporomandibular disorders (TMD) often complain and have limitation in masticatory function, which can be affected by a complex interaction of factors. The aim of this study was analyze the masticatory function in patients with TMD using surface electromyography (EMG) and masticatory efficiency (ME). Twenty-seven patients with TMD and 25 considered control (n), aged between 18 and 60 years, paired by age and gender, were evaluated according to RDC/TMD. In both groups were performed: EMG with chewing gum, clinical evaluation of habitual chewing with stuffed cookie (CE) (number of chewing strokes and time) and analysis of ME with fuchsin beads. Nonparametric statistical analyses were used (Mann-Whitney) for comparisons between groups, with 5% significance level. For all variables, the TMD group showed higher values than the control, with statistical significance for ME (pmasticatory function.

    Full Text Available Temporomandibular joint dysfunction is a term that covers a number of clinical problems that involves masticatory muscles, temporomandibular joints, and related structures, or both. Loss of tooth was an etiology of temporomandibular joint dysfunction. The purpose of this study was to obtain the description of temporomandibular joint dysfunction level that caused by tooth loss of elderly in three nursing home Bandung. This was a descriptive study using the survey method of the elderly in three nursing home Bandung. A total of 34 people consist 6 males and 28 females. The subjects were examined by symptoms of temporomandibular joint dysfunction and the dysfunction level was assessed by Helkimo Clinical Dysfunction Index. The result of this study shows that elderly in Nursing Home Bandung have mild dysfunction level was 7 (14.71%, moderate dysfunction level was 22 (64.71%, and severe dysfunction level is 5 (20.58%. It can be concluded that loss of the teeth is one of the etiologies of temporomandibular joint disorder. Based on the research conducted, it can be concluded that all elderly with teeth loss will have the temporomandibular joint disorder and the most severity happens based on teeth loss by using the Helkimo Clinical Disfunction Index score was the moderate disorder.

    Intermittent explosive disorder (IED) is aan externalizing externalising disorder characterized characterised by recurrent aggression episodes. Even though this disorder was described several decades ago, and it carries personal and social consequences, there is little in the medical scientific literature on this. bibliographic production about it is scanty. To perform a conceptualization conceptualisation of this disorder, through the review and bibliometric analysis of the available scientific articles. A search was performed in databases with the english English terms intermittent explosive disorder, impulse disorders control [MeSH], in combination with other terms. A bibliometric analysis in the GoPubMed® search engineer was also performed using all data obtained in the search. was also perfomed. IED prevalence ranges from 1.4% to 7%, it presents more frequently during middle adolescence, and with more noticeable repercussions in men males than in womenfemales. The psychopathological core of IED is the impulsive aggressive behaviour that presents in the form of «attacks» that occurs in response to a lower precipitating stimulus. Scientific publications about IED are few and relatively recent, and the vast majority is provided bycomes from the United States (56.56%), and headed by a single author. This fact highlights the need to replicate the findings described about the IED in order to demonstrate the validity and reliability of its diagnostic criteria. It is possible that doubts about the existence of a diagnosis lead have led to such a scant literature about the IED. Available studies about IED allow have allowed characterizing a group of subjects with episodes of impulsive aggression to be characterised, but this description requires replication in different latitudesneeds to be repeated in different areas.

    Temporomandibular joint is one of the most complicated joints of the body and plays an important role in the head and neck system. One of the factors affecting the temporomandibular joint and lead to temporomandibular disorder is anxiety with all the events causing it. The aim of this study was to determine a relationship between anxiety and temporomandibular disorders. In this prospective study, subjects were randomly selected. One hundred and thirty pre-university students in Isfahan were evaluated with Ketel's test of anxiety, exam stress test and temporomandibular disorder questionnaires. The evaluation was done in two stages 10 months and 1 month prior to the university entrance exam (Konkour), clinical assessments consisted of masticatory muscles and sternocleidomastoid muscle palpation, temporomandibular joint palpation for pain and noise and its movement, and mouth opening limitations. The Wilcoxon rank test and paired t-test were used to analyze the data and the P value under 0.05 was considered significant. The level of anxiety and occurrence of temporomandibular disorders were increased between two stages and had the highest level in the second stage. There was a significant increase between two stages (P<0.001). The parallel increase of temporomandibular disorders and anxiety between the two stages can suggest a possible relationship between anxiety and temporomandibular disorders. Therefore, the effect of anxiety in triggering temporomandibular disorder symptoms is probable.

    Otological symptoms (otalgia, subjective hearing loss, blocked ear sensation, tinnitus and vertigo) associated with temporomandibular disorders are documented features of Costen's syndrome. However, the origin of these symptoms and the causes of hearing loss are unknown. This study aimed to characterise hearing loss in a large number of patients with temporomandibular disorders. The causes of these symptoms were explored in patients with otological symptoms and normal audiometric findings. A prospective case study and literature review were performed. The audiometric features of 104 temporomandibular disorder patients were compared with those of 110 control participants. A large proportion of temporomandibular disorder patients had several otological symptoms. Twenty-five per cent of unilateral or bilateral temporomandibular disorder patients had either unilateral (ipsilateral) or bilateral hearing loss; respectively, which was usually mild (p = 0.001). Hearing loss was predominantly sensorineural. The main cause of otological symptoms (apart from otalgia) and of audiometric findings in temporomandibular disorder patients is postulated to be an altered middle-ear to inner-ear pressure equilibrium.

    The frequent concurrence of tinnitus and temporomandibular joint and masticatory muscle disorders (TMD) has led to the assumption that a possible relationship exists between these 2 conditions. The present prospective clinical study was conducted to assess the possible association between tinnitus and TMD and to investigate the effect of stomatognathic therapy on tinnitus distress. The prevalence of TMD and tinnitus was investigated in a consecutive series of 951 patients at the Department of Prosthetic Dentistry at the University Medical Center Regensburg, Germany. Patients with TMD and simultaneous tinnitus were included in the prospective clinical trial (n=25). Baseline examination comprised a detailed functional analysis, diagnosis of temporomandibular joint and masticatory muscle disorder, and a tinnitus questionnaire. All the participants received individual dental functional therapy (oral splints, physiotherapy). The effects of functional therapy on TMD and tinnitus symptoms were examined 3 to 5 months after the initiation of dental functional therapy. Means (standard deviations) were calculated, and 1-way ANOVA was used to investigate statistical differences (α=.05). The differences of the 2 binary outcomes were compared with the Pearson χ(2) test, and the relative risk was calculated. Prevalence of tinnitus was found to be 8 times higher in participants with TMD (30 of 82 [36.6%]) than in participants without TMD (38 of 869 [4.4%]). All the participants with unilateral TMD and unilateral tinnitus showed these conditions on the same side. Stomatognathic therapy improved tinnitus symptoms in 11 of 25 participants (44%). The results of this study and the prospective clinical trial showed a significant correlation between tinnitus and TMD. The observed treatment outcome suggests that dental functional therapy may have a positive effect on TMD-related tinnitus. Copyright © 2014 Editorial Council for the Journal of Prosthetic Dentistry.

  18. Somatoform disorders and recent diagnostic controversies.

    2007-12-01

    Classification is not a trivial matter. In Burmese Days, George Orwell writes, "It is devilish to suffer from a pain that is all but nameless. Blessed are they who are stricken only with classifiable diseases! Blessed are the poor, the sick, the crossed in love, for at least other people know what is the matter with them and will listen to their belly-achings with sympathy." Patients who have somatoform disorders are particularly susceptible to this Orwellian lamentation. They are afflicted by symptoms that defy simple explanations. As detailed in this article, there is a spectrum of medical and psychiatric factors that can cause or contribute to somatic symptom burden. Research is continuing to reveal the central mechanisms that may provide a common pathway for physical and psychologic symptoms. The dualism that places some somatic symptom disorders on Axis I and others on Axis III gradually may fade in the coming decades as what the unifying causes are among common symptoms and the multicausal nature of many symptoms are discovered. Meanwhile, the classification systems should continue to operate on pragmatic principles where mechanistic explanations are lacking. This will allow grouping patients into categories that inform research, scientific and patient communication, prognostication, and clinical management. Coupling a heuristic classification system with evidence-based measures for assessing severity and monitoring treatment outcomes are important steps in the optimal care of symptomatic patients.

    Most of the reports on instrumentalists' experiences of temporomandibular disorders (TMD) have been reported not by clinical examinations but by subjective questionnaires. The aim of this study was to investigate the clinical signs and subjective symptoms of TMD in a large number of instrumentalists objectively. A total of 739 musicians from a diverse range of instrument groups completed a TMD questionnaire. Among those who reported at least one symptom of TMD, 71 volunteers underwent clinical examinations and radiography for diag-nosis. Overall, 453 participants (61.3%) reported having one or more symptoms of TMD. The most frequently reported symptom was a clicking or popping sound, followed by temporomandibular joint (TMJ) pain, muscle pain, crepitus, and mouth opening limitations. Compared with lower-string instrumentalists, a clicking or popping sound was about 1.8 and 2 times more frequent in woodwind and brass instrumentalists, respectively. TMJ pain was about 3.2, 2.8, and 3.2 times more frequent in upper-string, woodwind, and brass instrumentalists, respectively. Muscle pain was about 1.5 times more frequent in instrumentalists with an elevated arm position than in those with a neutral arm position. The most frequent diagnosis was myalgia or myofascial pain (MFP), followed by disc displacement with reduction. Myalgia or MFP was 4.6 times more frequent in those practicing for no less than 3.5 hours daily than in those practicing for less than 3.5 hours. The results indicate that playing instruments can play a contributory role in the development of TMD.

    Full Text Available Introduction: Temporomandibular disorder (TMD treatment varies from conservative therapy to invasive procedures such as arthrocentesis. The procedure is simple and has speed, low cost, low morbidity and good patient acceptance. Literature variations, however, have been found about the type and volume of the solution used for the irrigation of temporomandibular joint (TMJ. Subjects and Methods: The aim of this study was to compare the results provided by two different volumes of 0.9% saline solution (100 ml and 250 ml used in arthrocentesis technique for TMD treatment. It included patients unresponsive to conservative treatment. Preoperative (T0 and postoperative evaluations were performed at T1 (30th day, T2 (60th day, and T3 (90th day, in which maximal mouth opening (MMO, pain, and the presence or absence of joint sounds were recorded. Patients were randomized into two groups: 1 – submitted to arthrocentesis using 100 ml of 0.9% saline solution in TMJ and 2 – arthrocentesis performed using 250 ml of 0.9% saline solution in each TMJ. Data were submitted to descriptive and comparative analyses for each parameter per group and between groups. The effect size was calculated according to Cohen test. Minimum detectable change (MDC was obtained and the sensibility was calculated. A statistical significance of 5% was established. Group 1 obtained increase in MMO and decrease in pain (statistically significant; in Group 2, pain decreased significantly. In Group 1, clicking decreased significantly. No statistical differences were found between groups (P = 0.333. MMO and pain results exceeded MDC, and sensibility was good. Conclusion: In conclusion, arthrocentesis is effective in TMD symptoms' relief, without statistical difference between the volumes used.

    BACKGROUND: Burning Mouth Syndrome (BMS) is a chronic disease characterized by absence of any lesions and burning of the oral mucosa associated to a sensation of dry mouth and/or taste alterations. The purpose of our study is to estimate signs and symptoms of Temporomandibular Disorders (TMD) in patients with BMS and to investigate for the existence of an association between BMS and TMD. MATERIALS AND METHODS: Forty-four BMS patients were enrolled; BMS subtype was established according to the classification of Lamey. After a gnathological evaluation, according to the protocol of the European Academy of Craniomandibular Disorders, patients were classified by RDC/TMD criteria. The data were compared and analyzed using a chi-square test to describe the existence of an association between BMS and TMD. RESULTS: 65.9% the BMS patients showed disorders classified as primary signs and symptoms of TMD according to RDC / TMD criteria, and 72.7% showed parafunctional habits. The chi-square test revealed a statistically significant association (p = 0.035) between BMS and TMD. CONCLUSION: The data suggest that there is a possible relationship not yet well understood between BMS and TMD, may be for neurophatic alterations assumed for BMS that could be also engaged in TMD pathogenesis.

  2. Headaches and myofascial temporomandibular disorders: overlapping entities, separate managements?

    2016-09-01

    There are relevant clinical overlaps between some of the painful temporomandibular disorders (TMD) and headache conditions that may hamper the diagnostic process and treatment. A non-systematic search for studies on the relationship between TMD and headaches was carried out in the following databases: PubMed, Cochrane Library and Embase. Important pain mechanisms contributing to the close association and complex relationship between TMD and headache disorders are as follows: processes of peripheral and central sensitisation which take place in similar anatomical areas, the possible impairment of the descending modulatory pain pathways and the processes of referred pain. In addition, the clinical examination does not always provide distinguishing information to differentiate between headaches and TMD. So, considering the pathophysiology and the clinical presentation of some types of headache and myofascial TMD, such overlap can be considered not only a matter of comorbid relationship, but rather a question of disorders where the distinction lines are sometimes hard to identify. These concerns are certainly reflected in the current classification systems of both TMD and headache where the clinical consequences of diagnosis such as headache attributed to or associated with TMD are uncertain. There are several similarities in terms of therapeutic strategies used to manage myofascial TMD and headaches. Considering all these possible levels of interaction, we reinforce the recommendation for multidisciplinary approaches, by a team of oro-facial pain specialists and a neurologist (headache specialist), to attain the most precise differential diagnosis and initiate the best and most efficient treatment. © 2016 John Wiley & Sons Ltd.

    2013-02-01

    The role of temporomandibular joint (TMJ) surgery is ill-defined, so a universal classification is needed to collate the evidence required to justify the surgical interventions undertaken to treat TMJ disorders. The aim of this article is to introduce a new classification that divides TMJ disorders into 5 categories of escalating degrees of joint disease that can be applied to TMJ surgery. Using a category scale from 1 to 5, with category 1 being normal, and category 5 referring to catastrophic changes to the joint, the new classification will provide the basis for enhanced quantitative and descriptive data collection that can be used in the field of TMJ surgery research and clinical practice. It is hoped that this new classification will form the basis of what will eventually become the universal standard surgical classification of TMJ disorders that will be adopted by both researchers and clinicians so that ultimately, the role of TMJ surgery will be based on evidence rather than conjecture.

    The relationships between temporomandibular joint (TMJ) disorders and cervical structure dysfunctions have already been demonstrated. The aim of the present study was to investigate functional and structural alterations of the head and neck of 17 individuals with TMJ disorders (TMD group), compared with a control group of 17 asymptomatic subjects in a cross-sectional design. The outcome variables included pain on palpation of the sternocleidomastoideus, superior trapezius and subocciptal muscles, as well as radiographic measures of alignment of the cervical spine and positioning of the hyoid bone. Cervical alignment, determined by measures of the cervical curvature angle, was investigated by the Cobb method. Independent Student t-tests were used to investigate differences between groups for all outcome variables (alpha TMJ disorders, when compared with asymptomatic subjects, presented higher levels of perception of pain in all cervical muscles (P < 0.0001). No significant differences were found between groups for the cervical alignment measures. In the TMD group, the position of the hyoid bone in relation to the cervical spine did not appear to be different from the control group.

    In treating patients with temporomandibular joint (TMJ) dysfunction it was noticed that tinnitus and vertigo were common in such patients and there was also muscular tension in jaw and neck. During treatment of these patients it was also noted that injection of lidocaine in a jaw muscle (m. pt. lat.) reduced not only their muscular problems but also that the tinnitus was reduced while the local anesthetic was active. Evaluation of 39 patients with disabling tinnitus, and all suffered from tinnitus, revealed that 10 of them had bilateral tinnitus and TMJ disorders revealed that pain in the face, temples or jaw occurred often among these patients. Many of such patients had also symptoms of cervical spine disorders, head, neck and shoulder pain, and limitations in side bending and rotation were also frequent complaints. One-third of these patients could influence tinnitus by jaw movements and 75% could trigger vertigo by head or neck movements. Treatment of jaw and neck disorders in 24 patients with Ménière's disease had a beneficial effect on not only their episodic vertigo but also on their tinnitus and aural fullness. At the 3-year follow-up, intensity of all symptoms were significantly reduced (p<0.001).

    To perform an integrative review of scientific bibliographic production on the use of superficial heat treatment for temporomandibular disorders. Research strategy : Literature review was accomplished on PubMed, LiLACS, SciELO, Bireme, Web of Science, and BBO databases. The following descriptors were used: hot temperature, hyperthermia induced, heat transference, temporomandibular joint, temporomandibular joint disorders, temporomandibular joint dysfunction syndrome, and their equivalents in Portuguese and Spanish. Articles that addressed the superficial heat for the treatment of temporomandibular disorders, published in English, Spanish, or Portuguese, between 1980 and 2013. The following data were collected: technique of applying superficial heat, duration of application, stimulated body area, temperature of the stimulus, frequency of application, and benefits. initially, 211 studies were found, but just 13 contemplated the proposed selection criteria. Data were tabulated and presented in chronological order. Several techniques for superficial heat application on treatment of temporomandibular disorders were found in the literature. The moist heat was the most widely used technique. Many studies suggested the application of heat for at least 20 minutes once a day. Most authors recommended the application of heat in facial and cervical regions. The heat treatment resulted in significant relief of pain, reduced muscle tension, improved function of the mandible, and increased mouth opening.

Thirty-eight of these patients completed 1-24 months of follow-up (short-term group) and 21 completed 11 months or longer of follow-up (long-term group). The two groups were evaluated statistically for pain (visual analogue scale), maximum mouth opening, lateral excursion, and protrusion. Both follow-up duration groups showed significant improvements when compared to baseline levels for almost all of the outcome variables (P<0.05). Single puncture temporomandibular joint arthrocentesis is an effective treatment method over both the short and long term.

    To evaluate the prevalence of temporomandibular dysfunction (TMD) and its association with perceived stress and common mental disorder (CMD) in academic students. This is s transversal observational study conducted at Universidade de Minas Gerais, Divinópolis Unit, in health science courses. To investigate the prevalence of TMD, the anamnestic index by Fonseca was used. Stress was assessed by the perceived stress scale, translated and adapted for the Brazilian population in 2006. To track CMD, we used the Self-Reporting Questionnaire (SRQ-20). Data were analyzed using SPSS version 13.0, adopting a 5% significance level. The prevalence of TMD in the sample was 71.9%, distributed as follows: Light TMD (50.0%), moderate (16.4%) and severe (5.5%), being more frequent among women (76.4%). Common mental disorders were present in 29.9% of participants. The average perceived stress was 30.9. The results of this study allow us to conclude that there is a statistically significant correlation between TMD and variables such as parafunctional habits, perceived stress and CMD.

    Understanding and treatment strategy for disc displacement of temporomandibular disorders (TMD) were discussed in the present review. It has been strongly recommended by the author that the treatment strategy for disc displacement, one subtype of TMD, should be mainly the reversible conservative treatment methods. The most important goal of treatment for disc displacement is to recover the mobility and function of the joint in order to improve the quality of the patient's life. Comprehensive assessments both from somatic and psychological aspects for each TMD patient are necessary, especially for the patients with chronic pain. Although the role of surgical operative treatments is very limited in the general treatment strategy for TMD, it is still important for a few patients who had definite diagnosis of intra-articular disorders, severe symptoms affecting the quality of patient's life and failed to response to the correct conservative treatments. It should be very careful to treat the TMD patients by surgical operation or irreversible occlusion treatments changing the natural denture of the patient, such as full mouth occlusional reconstruction and extensive adjustment of occlusion.

    Nearly 5% of the the world's population has temporomandibular disorder (TMD) severe enough to make them seek treatment. A third of the total population has at least one TMD symptom. There are different types of splints to treat TMD. In our study, we compared the success of two different appliances [stabilization splint (ss), nociceptive trigeminal inhibition splint (NTI)] by using Fonseca's questionnaire, the OHQoL-UK and visual analog scale (VAS). A total of 40 patients suffering from TMD were included in this study and answered questionnaires twice, at the beginning of the treatment and 3 months later. Regarding TMD alone, 39 patients (97.5%) had some degree of the disorder, 7 of of these cases being mild (17.5%), 15 moderate (37.5%), and 17 severe (42.5%). We analyzed posttreatment changes compared to baseline. Pain complaints decreased in both groups, and the OHQoL-UK revealed better quality of life after treatment. Based on the posttreatment Fonseca's questionnaires, significant changes in the patients' complaints in the group SS (p 0.05). Patients in both groups had fewer TMD complaints after TMJ treatment. According to the Fonseca's questionnaire, the patients' major TMD complaint was clenching-grinding, followed by pain in the craniomandibular joint, or earache.

    Dental students have high levels of anxiety that can affect not only academic performance but also increase the risk for other diseases. It is believed that the increase in the incidence of chronic orofacial pain in temporomandibular disorders (TMDs) may have an impact on the quality of life and general health of subjects. The aim of this study was to evaluate the prevalence of TMD in dental students and its association with general health, quality of life, and anxiety. Ninety students were evaluated by four questionnaires to determine the prevalence and sever-ity of TMD (Fonseca's questionnaire) and to quantify general health (General Health Questionnaire - GHQ), quality of life (World Health Organization Quality of Life - Brief version - WHOQOL-brief) and anxiety levels (State-Trait Anxiety Index - STAI). Approximately 58.9% of dental students presented TMD. Among the indicators of general health, psychologic stress (P = .010), distrust in their own performance (P = .012), and psychosomatic disorders (P = .020) showed a statistically significant difference with the presence of TMD. The four areas proposed in the questionnaire regarding quality of life, such as physical (P = .016), psychologic (P < .001), social (P = .045), and environmental (P = .017) factors also showed significant differences with the presence of TMD. A high prevalence of TMD was observed in dental students. In addition, some psychologic domains are important psychosocial indicators associated with the presence of TMDs.

    There is little information on bruxism related to illicit drug use. Prolonged drug use may damage the stomatognathic system via oral motor overactivity. The aim of the present study was to compare the rates of bruxism and temporomandibular disorders (TMDs) between prisoners with and without drug-use disorders, to evaluate the association between methadone treatment and bruxism and to assess the possible relationship between bruxism and pain. The sample included 152 male prisoners, 69 of whom were drug users maintained on methadone. All prisoners were examined by an experienced dentist and completed a questionnaire on their oral habits, with the aim of detecting signs or symptoms of TMD and/or bruxism. Additional data were collected from medical files. The prevalence of sleep bruxism and awake bruxism, but not of TMDs, was significantly higher among drug-user than non-drug user prisoners (52.2% vs. 34.9% for sleep bruxism, 59.7% vs. 30.1% for awake bruxism, and 46.3% vs. 25.6% for TMDs, respectively). Participants with awake bruxism were statistically more sensitive to muscle palpation compared with participants with sleep bruxism [rating scores (mean ± SD): 0.32 ± 0.21 vs. 0.19 ± 0.28, respectively]. An association was found between sleep bruxism and awake bruxism. It seems that there is a direct or an indirect association between methadone maintenance treatment and sleep bruxism or awake bruxism in male prisoners. © 2016 Eur J Oral Sci.

  19. The Pursuit of Happiness, Stress and Temporomandibular Disorders

    Full Text Available Mismanaging the pursuit of happiness causes negative psychological effects such as stress and disappointment. The resultant stress often manifests itself as psychological and physical health problems. We explore the problems of measuring happiness according to materialistic wealth and demonstrate that misinterpreting happiness can lead to a stress inducing pursuit. The happiness that human beings pursue is often material-based hedonism whereas eudaimonic happiness has been shown to be a by-product of the pursuit of meaningful activities. Pursuing a predefined happiness, the failure to achieve it and the resistance to it can create stress induced psychosomatic health problems; temporomandibular disorders (TMD are one such example. Masticatory myofascial pain syndrome is a form of TMD that has a strong association to psychological stress. In this paper the research on TMD associated facial pain across different socioeconomic status (SES groups is utilized to compare an objective, stress related physiological disorder with happiness data. We also discuss how the pressures of pursuing socially determined aesthetic happiness such as conforming to society’s expectations of smile and facial aesthetics can drive people to make surgical or orthodontic changes. This review proposes that pursuing happiness has the propensity to cause not only psychological stress but also negative behaviors. We aim to encourage further scientific research that will help to clarify this philosophical pursuit.

    Full Text Available Aim. Headache is one of the most common diseases associated with Temporomandibular Disorders (TMDs. The aim of this study was to evaluate, retrospectively, if headache influences TMD’s symptoms. Material and Methods. A total sample of 1198 consecutive TMD patients was selected. After a neurological examination, a diagnosis of headache, according to the latest edition of the International Classification of Headache Disorders, was performed in 625 subjects. Patients were divided into two groups based on presence/absence of headache: Group with Headache (GwH and Group without Headache (GwoH. Descriptive statistics and Chi-square index were performed. Results. Sociodemographic (gender, marital status, and occupation and functional factors, occlusion (occlusal and skeletal classes, dental formula, and occlusal abnormalities, and familiar pain did not show a statistically significant correlation in either group. Intensity and frequency of neck pain, arthralgia of TMJ, and myalgia showed higher correlation values in GwH. Conclusion. This study is consistent with previous literature in showing a close relationship between headache and TMD. All data underlines that headache makes pain parameters more intense and frequent. Therefore, an early and multidisciplinary treatment of TMDs should be performed in order to avoid the overlay of painful events that could result in pain chronicity.

    This study tested the hypothesis that muscle related temporomandibular disorder patients with cervical muscle pain exhibit greater degree of psychological distress compared with patients without cervical muscle pain and controls. Thirty-eight muscle related temporomandibular disorder patients including 10 patients with cervical muscle pain and 41 healthy individuals as controls participated in the study. State and trait anxiety levels were assessed with the Spielberger's state and trait anxiety inventory. Personality traits (extroversion, neuroticism, psychoticism and social desirability) were assessed using the Eysenck's personality questionnaire, and the pain intensities described over the muscles were recorded using a 100 mm visual analogue scale. The muscle related temporomandibular disorder patients, in general, exhibited significantly higher degrees of neuroticism and trait anxiety. The patients with cervical muscle pain demonstrated a significantly higher level of psychoticism compared with the patients without cervical muscle pain and the controls and a significantly higher state anxiety level than the controls. They also demonstrated higher pain intensities in masseter and temporalis muscles compared with patients without cervical muscle pain. It has been suggested that either subjects with psychological distress are prone to temporomandibular disorders, or psychological distress is a manifestation of existing chronic pain conditions. The present findings demand further investigations and broader approach in management, as muscle related temporomandibular disorder patients with cervical muscle pain were both physically and psychologically compromised to a greater degree compared with patients without cervical muscle pain.

    T2 relaxation time is a quantitative MR imaging parameter used to detect degenerated cartilage in the knee and lumbar intervertebral disks. We measured the T2 relaxation time of the articular disk of the temporomandibular joint in patients with temporomandibular disorders and asymptomatic volunteers to demonstrate an association between T2 relaxation time and temporomandibular disorder MR imaging findings. One hundred forty-four patients with temporomandibular disorders and 17 volunteers were enrolled in this study. An 8-echo spin-echo sequence for measuring the T2 relaxation times was performed in the closed mouth position, and the T2 relaxation time of the entire articular disk was measured. Patients were classified according to the articular disk location and function, articular disk configuration, presence of joint effusion, osteoarthritis, and bone marrow abnormalities. The T2 relaxation time of the entire articular disk was 29.3 ± 3.8 ms in the volunteer group and 30.7 ± 5.1 ms in the patient group (P = .177). When subgroups were analyzed, however, the T2 relaxation times of the entire articular disk in the anterior disk displacement without reduction group, the marked or extensive joint effusion group, the osteoarthritis-positive group, and the bone marrow abnormality-positive group were significantly longer than those in the volunteer group (P temporomandibular joint in patients with progressive temporomandibular disorders were longer than those of healthy volunteers. © 2014 by American Journal of Neuroradiology.

    Full Text Available This study examines the possible correlation between the prevalence of temporomandibular disorders (TMD and different head postures in the frontal and sagittal planes using photographs of undergraduate students in the School of Dentistry at the Universidade de Brasília - UnB, Brazil. In this nonrandomized, cross-sectional study, the diagnoses of TMD were made with the Research Diagnostic Criteria (RDC/TMD axis I. The craniovertebral angle was used to evaluate forward head posture in the sagittal plane, and the interpupillary line was used to measure head tilt in the frontal plane. The measurements to evaluate head posture were made using the Software for the Assessment of Posture (SAPO. Students were divided into two study groups, based on the presence or absence of TMD. The study group comprised 46 students and the control group comprised 80 students. Data about head posture and TMD were analyzed with the Statistical Package for the Social Sciences, version 13. Most cases of TMD were classified as degenerative processes (group III, followed by disk displacement (group II and muscle disorders (group I. There was no sex predominance for the type of disorder. No association was found between prevalence rates for head postures in the frontal plane and the occurrence of TMD. The same result was found for the association of TMD diagnosis with craniovertebral angle among men and women, and the group that contained both men and women. Abnormal head postures were common among individuals both with and without TMD. No association was found between head posture evaluated in the frontal and sagittal planes and TMD diagnosis with the use of RDC/TMD.

    Many studies have demonstrated the presence of somatosensory modulation changes at different sites in patients with temporomandibular disorders (TMDs) using different modalities. However, the neck area, a well-know condition related to TMD, remains unexplored. To assess the thermal pain threshold in patients with TMD and controls at cephalic and extra-cephalic areas, including the neck. Twenty female patients with TMDs diagnosed by the Research Diagnostic Criteria for TMD (RDC/TMD) and twenty age-matched controls underwent a first interview about neck pain and disability (NDI questionnaire). A blinded evaluator assessed the thermal pain threshold for cold (CPT) and heat (HPT) stimuli in accordance with an ascending method of limits of the Quantitative Sensory Testing at the following sites: periorbital, masseter, cervical posterior and ventral forearm. The groups were compared using a t-test with α = 5%. Patients with TMDs reported pain at higher temperature for cold stimuli in all sites (P < 0·05) and at lower temperature for heat stimuli in the right periorbital site (P < 0·05) than controls. Pain and disability due tothis symptom were reported more often in the TMD group (P < 0·05). Patients with TMD have pain modulation changes in the neck area as well, especially for cold stimuli, associated with higher disability and a higher report of neck pain than controls. These findings reinforce the evidence regarding the relationship between TMDs and neck pain. © 2016 John Wiley & Sons Ltd.

    The objective was to compare and correlate disability, pain intensity, the impact of headache on daily life and the fear of movement between subgroups of patients with chronic temporomandibular disorder (TMD). A cross-sectional study was conducted in patients diagnosed with chronic painful TMD. Patients were divided into: 1) joint pain (JP); 2) muscle pain (MP); and 3) mixed pain. The following measures were included: Craniomandibular pain and disability (Craniofacial pain and disability inventory), neck disability (Neck Dsiability Index), pain intensity (Visual Analogue Scale), impact of headache (Headache Impact Test 6) and kinesiophobia (Tampa Scale of Kinesiophobia-11). A total of 154 patients were recruited. The mixed pain group showed significant differences compared with the JP group or MP group in neck disability (p pain and disability (p pain and disability for the MP group (β = 0.62; p pain group, neck disability (β = 0.40; p pain and disability. Mixed chronic pain patients show greater craniomandibular and neck disability than patients diagnosed with chronic JP or MP. Neck disability predicted the variance of craniofacial pain and disability for patients with MP. Neck disability and kinesiophobia predicted the variance of craniofacial pain and disability for those with chronic mixed pain.

    The authors analyzed the clinical findings, radiological findings and their correlations in the temporomandibular joint disorders. 1. The most prevalent age group was in the first decade, then the second decade and the third decade. Female were more common with a ratio of 3.4 : 1. 2. The most common clinical findings was the pain on open mouth position (42.43%), then came the clicking and limitation of mouth opening. 3. The most common bone change on the condyle side was the erosion, then came the flattening, the osteopyte and the sclerosis in that orders. 4. In the case of the crepitus, the coarse crepitus showed more radiological change than the fine crepitus. 5. In the case of the mouth opening limitation, the evaluation of the translatory movement by transcranial projection was in accordance with the clinical evaluation. 6. The correlation between the clinical symptom and the condylar position within the mandibular fossa was not present and in the case of diagnosis of disc displacement, the transcranial projection seemed not to be able to substitute for the arthrography. 7. Radiographically, the most prevalent age group which showed the bone change was in the first, the second and the third decade. And the bone change seemed to have no relationship with aging.

    The objectives of the current study were to analyze the effects of orofacial myofunctional therapy (OMT) on the treatment of subjects with associated articular and muscular temporomandibular disorders (TMD). Thirty subjects with associated articular and muscular TMD, according to the Research Diagnostic Criteria (RDC/TMD), were randomly divided into groups: 10 were treated with OMT (T group), 10 with an occlusal splint (OS group), and 10 untreated control group with TMD (SC). Ten subjects without TMD represented the asymptomatic group (AC). All subjects had a clinical examination and were interviewed to determine Helkimo's Indexes (Di and Ai), the frequency and severity of signs and symptoms, and orofacial myofunctional evaluation. During the diagnostic phase, there were significant differences between groups T and AC. There were no significant differences between group T and OC and SC groups. During the final phase, groups T and OS presented significant improvement, however, the group T presented better results and differed significantly from group OS regarding the number of subjects classified as Aill; the severity of muscular pain and TMJ pain; the frequency of headache and the muscles and stomatognathic functions. The group T differed significantly from the SC group but no longer differed significantly from the AC group. OMT favored a significant reduction of pain sensitivity to palpation of all muscles studied but not for the TMJs; an increased measure of mandibular range of motion; reduced Helkimo's Di and Ai scores; reduced frequency and severity of signs and symptoms; and increased scores for orofacial myofunctional conditions.

    To investigate the prevalence of bruxism and signs of temporomandibular disorders (TMDs) among psychiatric patients compared with a healthy population and to assess the effect of psychiatric medications on the parameters studied. Subjects included 77 psychiatric patients under treatment at 2 psychiatric hospitals in Israel and 50 healthy individuals (control). One experienced calibrated examiner performed the clinical examination (presence of bruxism and signs of TMD). Abnormal attrition was evident in 46.8% of the psychiatric patients compared with 20% in the controls (P prevalence of joint clicks and no association between time of receiving treatment with dopamine antagonists (or any other psychotropic drugs) and TMD signs and symptoms. The higher prevalence of bruxism and signs of TMD in psychiatric patients is a major clinical comorbidity. Whether it is a manifestation of the abnormal central nervous system of psychiatric patients or neuroleptic-induced phenomenon deserves further attention. The exact factors that affect the pain experience in these patients should be evaluated as well.

    Intramuscular injections of botulinum toxin of type A (BoNTA) can release tension from masticatory and cervical muscles. Intra-articular injections relieve pain and sometimes diminish joint clicking and locking that occur during mouth opening. Intramuscular injection of BoNTA is performed in our department since 2002. Injected muscles are masseter and temporal muscles. Later on, intra-articular injections of sodium hyaluronate were added, followed on a later stage by intra-articular injections of BoNTA for patients presenting with pain higher than 5/10 on an analogic visual scale. Eighty-five percent of the patients treated with intramuscular BoNTA injection improved. Total or partial pain relief was obtained in 95 % of the patients after intra-articular sodium hyaluronate injections. Seventy-six percent of the 56 patients treated by mean of intra-articular BoNTA injections improved, sometimes with a complete pain relief. These different techniques allow for good results, even if they do not represent a revolution in the treatment of temporomandibular disorders. In the hands of experienced practitioners, they have a low morbidity, are well accepted and are cost-effective. Copyright © 2016. Published by Elsevier Masson SAS.

    The association between temporomandibular disorders (TMDs) and headaches, cervical spine dysfunction, and fibromyalgia is not artefactual. The aim of this review is to describe the comorbid relationship between TMD and these three major painful conditions and to discuss the clinical implications and the underlying pain mechanisms involved in these relationships. Common neuronal pathways and central sensitization processes are acknowledged as the main factors for the association between TMD and primary headaches, although the establishment of cause-effect mechanisms requires further clarification and characterization. The biomechanical aspects are not the main factors involved in the comorbid relationship between TMD and cervical spine dysfunction, which can be better explained by the neuronal convergence of the trigeminal and cervical spine sensory pathways as well as by central sensitization processes. The association between TMD and fibromyalgia also has supporting evidence in the literature, and the proposed main mechanism underlying this relationship is the impairment of the descending pain inhibitory system. In this particular scenario, a cause-effect relationship is more likely to occur in one direction, that is, fibromyalgia as a risk factor for TMD. Therefore, clinical awareness of the association between TMD and painful comorbidities and the support of multidisciplinary approaches are required to recognize these related conditions.

    Full Text Available OBJECTIVE: To assess the frequency and severity of the signs and symptoms of temporomandibular disorders (TMD, the frequency of parafunctional oral habits and the correlation between the variables by means of the patients' perception regarding their problem. METHODS: One hundred patients diagnosed with TMD, through a clinical examination of their masticatory system, answered the questions of a previously published protocol concerning the signs and symptoms most frequently reported in the literature. RESULTS: According to the results from the non parametric statistical analysis, the frequency for the following signs and symptoms was significant: Fatigue and muscle pain, joint sounds, tinnitus, ear fullness, headache, chewing impairment and difficulty to yawn (p<0.01 and otalgia (p<0.05. As to the parafunctional oral habits, there was a significant presence of teeth clenching during the day and night (p<0.01 and teeth grinding at night (p<0.05. The variable correlation analysis showed that there was a positive correlation between symptom frequency and severity; age was correlated with the presence of otalgia, cervical pain and teeth sensitivity, besides being correlated with muscle and joint pain severity. Habit frequency was negatively correlated with age. TMD duration was also positively correlated with the symptoms of tinnitus, ear fullness, muscle and joint pain. CONCLUSION: The study results showed that the anamnestic assessment using ProDTMMulti can predict the severity of the TMD case.

It was predominantly muscular (77.4%), though 33.3% showed alteration of the mouth-opening pattern, 34% showed joint noises (clicks). The most compromised mandibular function was chewing (6%). These results contrast with reports in the bibliography, specifically in terms of muscle pain sites and headaches, probably explained by different instruments used. Conclusion The prevalence of TTM is in contrast among different studies. It is necessary to place emphasis on the need to evaluate these factors during the childhood and adolescence with validated instruments.

    Introduction: The temporomandibular disorders (TMDs) have been identified as the most important cause of pain in the facial region. The low level laser therapy (LLLT) has demonstrated to have an analgesic, anti-inflammatory and biostimulating effects. The LLLT is a noninvasive, quick and safe, non-pharmaceutical intervention that may be beneficial for patients with TMDs. However the clinical efficiency of LLLT in the treatment of this kind of disorders is controversial. Objectives: Literature review in reference to the use of LLLT in the treatment of TMDs, considering the scientific evidence level of the published studies. Material and Methods: A MEDLINE and COCHRANE database search was made for articles. The keywords used were “temporomandibular disorders” and “low level laser therapy” or “phototherapy” and by means of the Boolean operator “AND”. The search provided a bank of 35 articles, and 16 relevant articles were selected to this review. These articles were critically analyzed and classified according to their level of scientific evidence. This analysis produced 3 literature review articles and 13 are clinical trials. The SORT criteria (Strength of Recommendation Taxonomy) was used to classify the articles. Results: Only one article presented an evidence level 1, twelve presented an evidence level 2, and three presented an evidence level 3. According to the principle of evidence-based dentistry, currently there is a scientific evidence level B in favor of using LLLT for treatment of TMDs. Discussion and conclusions: Publications on the use of LLLT for treatment of TMDs are limited making difficult to compare the different studies due to the great variability of the studied variables and the selected laser parameters. The great majority of the studies concluded that the results should be taken with caution due to the methodological limitations. Key words:Low level laser therapy; phototherapy; temporomandibular joint disorders. PMID:23722130

    Full Text Available OBJECTIVE: This study, through a systematic literature review, aims to analyze the effectiveness of Botulinum Toxin as a treatment for masticatory myofascial pain and muscles temporomandibular disorders (TMD. METHODS: Survey in research bases: MEDLINE, Cochrane, EMBASE, Pubmed, Lilacs and BBO, between the years of 1966 and April 2011, with focus in randomized or quasi-randomized controlled clinical trials, blind or double-blind. RESULTS: After applying the inclusion criteria, 4 articles comprised the final sample: 3 were double-blind randomized controlled clinical trials and 1 was single-blind randomized controlled clinical trial. CONCLUSIONS: According to the literature, there is lack of evidence about the real effectiveness of botulinum toxin in the treatment of masticatory myofascial pain and muscular TMD. Thus, further randomized controlled clinical trials, with representative samples and longer follow-up time, to assess the real effectiveness of the technique are needed.OBJETIVO: este trabalho, por meio de uma revisão sistemática da literatura, teve como objetivo analisar a efetividade da toxina botulínica como tratamento para dor miofascial mastigatória e disfunções temporomandibulares (DTM musculares.

    Temporomandibular disorder (TMD) is still not defined with respect to the point of an entity, terminological problems, and clinical classification and gradings. Moreover, diagnostic problems of internal deranegement and osteodeformity at the temporomandibular joint such as type IV and mechanism of bone remodeling at condylar head are also still not clear. In this investigation, we tried to classify the severity and progressive grading according to the symptoms and objective laboratory data taken from soft tissues such as muscles related to mastication, discs and ligaments, and hard tissues such as condylar head and temporal bone changes around the temporomandibular joint. Preliminary diagnostic clinical tool of the assessment of temporomandibular joint by maens of bone scintigraphy was attributed to the additional diagnostic procedure and research for the bone remodeling for the temporomandibular disorder because this can be defined between subjective and objective symptoms in this disorder. Bone scintigraphy will solve many problems concerning undefined degenerative bone changes in TMD, enable more accurate diagnosis, and the selection of treatment and prognosis in future investigation. Also, it is believed single photon emission computed tomography (SPECT) nuclear bone imaging is a highly accurate diagnostic method for craniomandibular disorders. (author)

    To assess, by systematic review of the literature, (1) the prevalence and incidence of temporomandibular disorder (TMD) pain after whiplash trauma, and (2) whether treatment modalities commonly used for TMD are equally effective in patients with solely TMD pain and those with TMD/whiplash-associated disorders (WAD) pain. A systematic literature search of the PubMed, Cochrane Library, and Bandolier databases was conducted from January 1966 through October 2012. The systematic search identified 125 articles. After an initial screening of abstracts, 45 articles were reviewed in full text. Two investigators evaluated the methodological quality of each identified study. Eight studies on prevalence/incidence of TMD pain in WAD and four studies on interventions in TMD pain and WAD met the inclusion criteria. The reported median prevalence of TMD pain after whiplash trauma was 23% (range 2.4% to 52%) and the incidence ranged from 4% to 34%. For healthy controls, the reported median prevalence was 3% (range 2.5% to 8%) and the incidence ranged from 4.7% to 7%. For patients with a combination of TMD pain and WAD, treatment modalities conventionally used for TMD, such as jaw exercises and occlusal splints, had less of an effect (median improvement rate of 48%, range 13% to 68%) compared to TMD patients without a whiplash injury (75%, range 51% to 91%). There is some evidence that prevalence and incidence of TMD pain is increased after whiplash trauma. The poorer treatment outcome suggests that TMD pain after whiplash trauma has a different pathophysiology compared to TMD pain localized to the facial region.

    Professional violin playing has been associated with a predisposition to develop temporomandibular disorder (TMD). There are a number of risk factors, including physical trauma from the playing posture and the presence of parafunctional habits. Music performance anxiety (MPA) may also be a factor, as it has been associated with playing-related musculoskeletal disorders (PRMD). To evaluate a possible association between the presence of TMD and the level of MPA in violin players. An observational study using a written questionnaire that retrieved data related to TMD symptoms (Fonseca Anamnestic Questionnaire), MPA level (Kenny Music Performance Anxiety Inventory, K-MPAI), instrument practice time, chinrest type, sex and age. Descriptive, bivariate and logistic regression analyses were conducted. Ninety-three professional or semi-professional violinists performing in and around Lisbon, Portugal, completed the questionnaire (73% response rate). TMD was present in 50 violinists (58%). There was a statistically significant association between the presence of TMD and high MPA levels (P < 0.001) and the most anxious violinists were six times (95% confidence interval 2.51-15.33; P < 0.001) more likely to report TMD symptoms when compared with the least anxious players. Violin players had a high prevalence of reported TMD symptoms, which was significantly associated with high MPA levels. It may therefore be necessary to address psychological and physical factors simultaneously in musicians who do not improve with physical therapy alone. © The Author 2016.

    To explore potential differences in characteristics of patients that might account for sex-specific differences in temporomandibular disorders (TMD). A total of 502 patients presenting with TMD during 2000 to 2002 at the Outpatient Unit for Functional Disorders of the Medical University of Vienna underwent detailed evaluation of their medical history and assessment of clinical findings. The data obtained were assessed for sex-specific differences by analysis of variance and multiple regression. Overall, 404 females (mean age ± SD: 40 ± 16 years; range 12 to 96 years) and 98 males (mean age 41 ± 16 years; range 16 to 78 years) were included. Their rating of their pain on a visual analog scale (VAS) showed a significantly higher pain intensity for females than for males (P = .004). Clinical assessment showed a significantly lower degree of mouth opening for females than for males (P TMJ) and for the bite class of the patients, bite anomalies were significantly more frequent in male patients (P = .03). Palpation of masticatory muscles and the TMJ revealed significantly higher tenderness on palpation in female as compared to male patients (P = .001). Grouping by clicking, crepitation, and bruxism also showed greater pain (VAS) and more tenderness on palpation in females versus males. Females also showed peaks of prevalence of TMD in the age group below 25 years and in the group 55 to 60 years, whereas males had a more even age distribution. No external factors, such as exposure to stress, were found that moderated the sex difference. Female TMD patients showed greater pain and muscle tenderness on palpation as compared to male TMD patients. They also showed a different age distribution of prevalence of TMD. These results were independent of subjective symptoms, clinical findings, and external factors.

    The design of a diving regulator's mouthpiece increases the risk of a temporomandibular disorder (TMD) in scuba divers. The total weight of a diving regulator is reflected directly on the temporomandibular joint, causing articular and periarticular disorders. In the current study, the prevalence of TMD in scuba divers triggered during diving certification training is investigated. We also aimed to determine the factors that lead to TMD during diving training and clarify the observation that there is an increased incidence of TMD in inexperienced divers. The study was held between 2006 and 2011. Ninety-seven divers were referred with the complaint of pain around temporomandibular area. The divers were classified according to their diving experience. Symptoms and signs of TMD were graded. Fourteen divers were diagnosed with TMD. Temporomandibular disorder was seen more frequently in inexperienced divers than in experienced divers (P = 0.0434). The most prevalent symptom was an increased effort for mouthpiece gripping. Temporomandibular joint tenderness and trigger point activation were the mostly seen physical signs. Thirteen divers had an improvement with therapy. The increased effort for stabilizing the mouthpiece is a recognized factor in TMD development. Attention must be paid to an association of scuba diving with TMDs, especially in inexperienced divers having a scuba certification training.

    The objective of this systematic review was to find sufficient evidence to deny or accept the association between the head and cervical posture and temporomandibular disorders (TMDs), and thus assist health professionals in the evaluation and treatment of patients with TMDs. A search was conducted through all publications written in English about this topic using the databases from Medline, ISI Web of Science, EMBASE, PubMed and Lilacs. The abstracts that fulfilled the initial guideline were retrieved and evaluated to ensure they met the inclusion criteria. To assess the methodological quality of the studies, we developed a questionnaire considering the following criteria: participant's eligibility, control group, diagnosis of TMDs, posture diagnosis and randomisation. Twenty-two studies were selected as potential studies based on their abstracts. Only seventeen studies actually fulfilled the inclusion criteria. The search provided information about the methodological quality of the studies, in which several methodological defects were found. The evidence presented in this systematic review shows that the relation between TMDs and the head and neck posture is still controversial and unclear. The insufficient number of articles considered of excellent methodological quality is a factor that hinders the acceptance or denial of this association. © 2013 John Wiley & Sons Ltd.

  6. Pain Mechanisms and Centralized Pain in Temporomandibular Disorders

    Until recently, most clinicians and scientists believed that the experience of pain is perceptually proportional to the amount of incoming peripheral nociceptive drive due to injury or inflammation in the area perceived to be painful. However, many cases of chronic pain have defied this logic, leaving clinicians perplexed as to how patients are experiencing pain with no obvious signs of injury in the periphery. Conversely, there are patients who have a peripheral injury and/or inflammation but little or no pain. What makes some individuals experience intense pain with minimal peripheral nociceptive stimulation and others experience minimal pain with serious injury? It is increasingly well accepted in the scientific community that pain can be generated and maintained or, through other mechanisms, suppressed by changes in the central nervous system, creating a complete mismatch between peripheral nociceptive drive and perceived pain. In fact, there is no known chronic pain condition where the observed extent of peripheral damage reproducibly engenders the same level of pain across individuals. Temporomandibular disorders (TMDs) are no exception. This review focuses on the idea that TMD patients range on a continuum—from those whose pain is generated peripherally to those whose pain is centralized (i.e., generated, exacerbated, and/or maintained by central nervous system mechanisms). This article uses other centralized chronic pain conditions as a guide, and it suggests that the mechanistic variability in TMD pain etiology has prevented us from adequately treating many individuals who are diagnosed with the condition. As the field moves forward, it will be imperative to understand each person’s pain from its own mechanistic standpoint, which will enable clinicians to deliver personalized medicine to TMD patients and eventually provide relief in even the most recalcitrant cases.

    The somatosensory phenotype of Chinese temporomandibular disorders (TMD) patients is not sufficiently studied with the use of contemporary techniques and guidelines. A standardized quantitative sensory testing (QST) battery consisting of 13 parameters with a stringent statistical protocol developed by the German Research Network on Neuropathic Pain was performed over the most painful and corresponding contralateral sites as well as the right hand of 40 Chinese patients with TMD and pain classified according to the Diagnostic Criteria for TMD (DC/TMD). The same QST protocol was performed bilaterally over the infraorbital, mental, and hand regions of 70 age- and gender-stratified healthy Chinese controls. Z-scores and loss/gain scores were computed for each TMD patient. For patients, 82.5 % had somatosensory abnormalities in the painful facial region, while 60.0 % had abnormalities confined to the right hand. The most frequent abnormalities were somatosensory gain to pinprick (35.0 %) and pressure (35.0 %) stimuli, somatosensory loss to pinprick (25.0 %), cold (22.5 %), and heat (15.0 %) nociceptive stimuli. The most frequent loss/gain score was L0G2 (no somatosensory loss combined with a gain of mechanical somatosensory function) for both the facial (40.0 %) and hand (27.5 %) regions. Involving side-to-side differences in the evaluation increased the diagnostic sensitivity by 2.5-25.0 % across different parameters. Somatosensory abnormalities were commonly detected in Chinese TMD pain patients both within and outside the primary painful region, strongly indicating disturbances in the central processing of somatosensory stimuli. The individual variations in somatosensory abnormalities indicate a possible need for development of individualized TMD pain management.

    Some studies have shown a relationship between temporomandibular disorders (TMD) and dysphonia, as well as quality of life in oral health. The purpose of this study was to investigate the correlation between severity of vocal self-perception and TMD severity and the correlation between oral health-related quality of life impairment and TMD severity. Thirty-three women aged 20 to 40 years, with or without complaint of dysphonia, were recruited at the Bauru campus of the University of São Paulo, Brazil, and the local community. All participants were subjected to an investigation of quality of life related to dental and speech aspects by the application of Oral Health Impact Profile-short form (OHIP-14) and the Voice-Related Quality of Life (V-RQOL) protocol. Also, a questionnaire was applied to detect the presence and severity of TMD. There was significant correlation between TMD and quality of life for all aspects analyzed in the oral health protocol, except for function and physical limitation (p>0.05). There was negative correlation between TMD and voice-related quality of life in the total score (p=0.007) as weel as physical (p=0.008) and socio-emotional aspects (p=0.017). In addition, there was statistically significant correlation between TMD and vocal self-perception (p=0.037). There is an association between TMD severity, voice-related and oral health-related quality of life. It is important to investigate in future studies the vocal self perception as well as the oral and voice conditions in patients with TMD.

    To document the frequency of self-care in a clinical sample of patients with myofascial temporomandibular disorder (TMD) pain; report the perceived relief and control of pain for each of the self-care behaviors; and to test for associations between the frequency and efficacy of each self-care behavior and pain, depression and sleep quality, as assessed during a clinical visit, and to determine whether the frequency was associated with changes in pain intensity, depression, and sleep quality 30 days later. The sample consisted of 99 female and 27 male myofascial TMD pain patients who were participants in a multidisciplinary facial pain evaluation program. The subjects participated in a structured interview during a clinical visit and a follow-up telephone interview 30 days later. The interviews included questions about self-care, including resting, relaxation techniques, massage, hot and/or cold packs, home remedies, stretching or exercise, herbal remedies, and the use of vitamins or nutritional supplements for pain. The passive self-care behaviors, such as resting when experiencing pain (66%) and relaxation techniques (62%), were the most commonly used. Patients reported that hot or cold packs (5.3, 0-to-10 scale) and massage (4.7) provided the greatest relief from pain, whereas resting (4.9), relaxation (4.8), and massage (4.8) resulted in the greatest ability to control pain. The most striking finding was that initial levels of pain or change in pain were not consistently associated with self-care use; however, psychosocial outcomes of depression and sleep quality were associated with self-care frequency and reported efficacy and improved in relation to patient-reported self-care frequency. Since people with chronic myofascial TMD pain engage in a range of pain self-care strategies, clinicians need to discuss self-care with patients regularly.

    To gain a better understanding of temporomandibular disorders (TMD) pain in adolescents, it is important to study the factors associated with its presence. Therefore, the aim of this study was to investigate potential predictors for TMD pain in adolescents, thereby including a diversity of factors from the biopsychosocial model to determine the strongest predictors. The sample of this cross-sectional study consisted of 1094 adolescents. The presence of TMD pain was assessed using the RDC/TMD, Axis I. Apart from demographical characteristics, the roles of parafunctional habits, psychosocial aspects, menarche and other bodily pain complaints were evaluated. Single and multiple logistic regression models were used to identify associations between the predictor variables and TMD pain. Painful TMD had a prevalence of 25·5%. Logistic regression analyses showed that TMD pain was associated with sleep bruxism (OR = 1·8 95% CI = 1·34-2·34), awake bruxism (OR = 2·1 95% CI = 1·56-2·83), other parafunctional habits (OR = 2·2 95% CI = 1·17-4·08) and bodily pain complaints (OR = 5·0 95% CI = 3·48-7·28). Parafunctional habits and other bodily pain complaints may play an important role in the presence of TMD pain in adolescents. Of course, it remains unclear whether the observed associations between the investigated factors and the adolescent's TMD pain have a true causal linkage. © 2014 John Wiley & Sons Ltd.

    To determine whether patients with myogenous or mixed (ie, myogeneous plus arthrogeneous) temporomandibular disorders (TMD) had different head and cervical posture measured through angles commonly used in clinical research settings when compared to healthy individuals. One hundred fifty-four persons participated in this study. Of these, 50 subjects were healthy, 55 subjects had myogenous TMD, and 49 subjects had mixed TMD (ie, arthrogenous plus myogenous TMD). A lateral photograph was taken with the head in the self-balanced position. Four angles were measured in the photographs: (1) Eye-Tragus-Horizontal, (2) Tragus-C7-Horizontal, (3) Pogonion-Tragus-C7, and (4) Tragus-C7-Shoulder. Alcimagen software specially designed to measure angles was used in this study. All of the measurements were performed by a single trained rater, a dental specialist in orthodontics, blinded to each subject's group status. The only angle that reached statistical significance among groups was the Eye-Tragus-Horizontal (F = 3.03, P = .040). Pairwise comparisons determined that a mean difference of 3.3 degrees (95% confidence intervals [CI]: 0.15, 6.41) existed when comparing subjects with myogenous TMD and healthy subjects (P = .036). Postural angles were not significantly related to neck disability, jaw disability, or pain intensity. Intrarater and interrater reliability of the measurements were excellent, with intraclass correlation coefficient (ICC) values ranging between 0.996-0.998. The only statistically significant difference in craniocervical posture between patients with myogenous TMD and healthy subjects was for the Eye-Tragus-Horizontal angle, indicating a more extended position of the head. However, the difference was very small (3.3 degrees) and was judged not to be clinically significant.

    Objective: : The purpose of this study is to determine the prevalence of radiographic presence of otomastoiditis while examining temporomandibular joint (TMJ) disorders in magnetic resonance images (MRI) in a series of 2270 temporomandibular joint magnetic resonance images and to examine the relationship between otomastoiditis and TMJ disorders. Materials and methods: : 2270 temporomandibular joint magnetic resonance images and patients' data were retrospectively investigated. Magnetic resonance images were obtained from the patients who referred to Osaka University Dental Hospital Outpatient Clinic with TMJ complaints for the last four years (from January 1998 to January 2003). The patients, who were diagnosed as otomastoiditis based on their temporomandibular joint magnetic resonance images, were sent to Osaka University Hospital Department of Otolaryngology for a medical consultation in order to have their pathologies certified following their MR process. Age and sex were recorded for all patients and for otomastoiditis cases; location of the disease, symptoms of patients and TMJ findings were noted as well. Results: : Seven patients were diagnosed as acute otomastoiditis and one patient diagnosed as chronic active otitis media with cholesteatoma in the series of 2270 MR, which were representing a prevalence of 0.39%. Neurilemoma diagnosed in left mastoid process in one patient. The final diagnoses of all patients were made after medical consultation. Conclusion: : While examining temporomandibular joint magnetic resonance images; it is not only important to examine just the TMJ structures, but also to look at the nearby anatomical features to check evidence for inflammatory disease.

    Full Text Available Objectives: Mandibular advancement device therapy is effectively used in the treatment of obstructive sleep apnea, but also several side effects in the masticatory system have been reported. The aim of this study was to evaluate the subjective symptoms and clinical signs of temporomandibular disorders connected to mandibular advancement device therapy. Material and Methods: The material consisted of 15 patients (9 men and 6 women, mean age 51.1 years, range 21 to 70 years diagnosed with obstructive sleep apnea (OSA. Subjective symptoms and clinical temporomandibular disorders (TMD signs were recorded at the beginning of the treatment (baseline and at 1-month, 3-month, 6-month and 24-month follow-ups. The degree of TMD was assessed using the anamnestic (Ai and the clinical dysfunction index (Di of Helkimo. For assessing the effect of TMD the patients were divided in discontinuing and continuing groups. Results: According to Ai and Di, the severity of TMD remained unchanged during the follow-up in most of the patients. Temporomandibular joint (TMJ crepitation was found more frequently in discontinuing patients at all follow-ups. The difference was statistically significant (P < 0.05 at the six-month follow-up. Masticatory muscle pain during palpation was a frequent clinical sign at the baseline and during the follow-up period but the difference between discontinuing and continuing patients was not significant. Conclusions: It seems that signs and symptoms of temporomandibular disorders do not necessarily increase during long-term mandibular advancement device therapy. However, it seems that patients with clinically assessed temporomandibular joint crepitation may discontinue their mandibular advancement device therapy due to temporomandibular disorders.

    Full Text Available Abstract Background Temporomandibular joint disorders (TMJD are multifactor, complex clinical problems affecting approximately 60–70% of the general population, with considerable controversy about the most effective treatment. For example, reports claim success rates of 70% and 83% for non-surgical and surgical treatment, whereas other reports claim success rates of 40% to 70% for self-improvement without treatment. Therefore, the purpose of this study was to (1 identify systematic reviews comparing temporomandibular joint disorder surgical and non-surgical treatment, (2 evaluate their methodological quality, and (3 evaluate the evidence grade within the systematic reviews. Methods A search strategy was developed and implemented for MEDLINE, Cochrane Library, LILACS, and Brazilian Dentistry Bibliography databases. Inclusion criteria were: systematic reviews (± meta-analysis comparing surgical and non-surgical TMJD treatment, published in English, Spanish, Portuguese, Italian, or German between the years 1966 and 2007(up to July. Exclusion criteria were: in vitro or animal studies; narrative reviews or editorials or editorial letters; and articles published in other languages. Two investigators independently selected and evaluated systematic reviews. Three different instruments (AMSTAR, OQAQ and CASP were used to evaluate methodological quality, and the results averaged. The GRADE instrument was used to evaluate the evidence grade within the reviews. Results The search strategy identified 211 reports; of which 2 were systematic reviews meeting inclusion criteria. The first review met 23.5 ± 6.0% and the second met 77.5 ± 12.8% of the methodological quality criteria (mean ± sd. In these systematic reviews between 9 and 15% of the trials were graded as high quality, and 2 and 8% of the total number of patients were involved in these studies. Conclusion The results indicate that in spite of the widespread impact of TMJD, and the multitude of

    Full Text Available OBJECTIVE: The aim of this study was to determine the prevalence and the relation between the main occlusal factors and the temporomandibular disorder (TMD. METHODS: We analyzed 100 patients (50 diagnosed with TMD and 50 asymptomatic volunteers, control group through a questionnaire that classified TMD as absent, mild, moderate and severe. Then, an evaluation was made of intraoral occlusal factors: Absence of posterior teeth, wear facets, overjet, overbite, open bite, posterior crossbite, sagittal relationship (Class I, II and III, centric relation discrepancy for maximum intercuspation, anterior guidance and balancing occlusal interference. The c² examined the association between TMD and considered occlusal variables. RESULTS: The prevalence of studied occlusal factors was higher in patients with moderate and severe TMD. Statistically significant results were found on: Absence of five or more posterior teeth, overbite and overjet greater than 5 mm, edge-to-edge bite, posterior crossbite, Class II and III, the absence of effective anterior guide and balancing side interferences. CONCLUSIONS: Indeed, it is concluded that there is a relationship between TMD and occlusal factors, however it can not be told to what extent these factors are predisposing, precipitating or perpetuating the disease. Therefore, despite its multifactorial etiology, one can not neglect the occlusal analysis of these patients.OBJETIVO: o presente estudo teve como objetivo verificar a prevalência e relação dos principais fatores oclusais com a disfunção temporomandibular.

    Conclusion: There was a high prevalence of TMD in RA patients. The severity of TMD variably correlated with RA severity. Clinically, a high score of hand-joint space narrowing may serve as an early indicator of RA patients at risk of severe TMD. This may facilitate early management and prevent the functional impairment of the temporomandibular joint.

    The purpose of the present study was to correlate the degree of temporomandibular disorder (TMD) severity and skin temperatures over the temporomandibular joint (TMJ) and masseter and anterior temporalis muscles. This blind cross-sectional study involved 60 women aged 18-40 years. The volunteers were allocated to groups based on Fonseca anamnestic index (FAI) score: no TMD, mild TMD, moderate TMD, and severe TMD (n = 15 each). All volunteers underwent infrared thermography for the determination of skin temperatures over the TMJ, masseter and anterior temporalis muscles. The Shapiro-Wilk test was used to determine the normality of the data. The Kruskal-Wallis test, followed by Dunn's test, was used for comparisons among groups according to TMD severity. Spearman's correlation coefficients were calculated to determine the strength of associations among variables. Weak, positive, significant associations were found between FAI score and skin temperatures over the left TMJ (rs = 0.195, p = 0.009) and right TMJ (rs = 0.238, p = 0.001). Temperatures over the right and left TMJ were significantly higher in groups with more severe TMD (p < 0.05). FAI score was associated with skin temperature over the TMJ, as determined by infrared thermography, in this sample. Women with more severe TMD demonstrated a bilateral increase in skin temperature.

    This study was designed to investigate the efficacy of the temporomandibular joint arthrocentesis with and without injection of sodium hyaluronate (SH) in the treatment of temporomandibular joint disorders. A total of sixty two TMJs in 34 males and 28 females aged 20-65 years comprised the study material. The patients' complaints were limited mouth opening, TMJ pain, and joint noises during function. Patients were randomly divided into 2 groups in which arthrocentesis plus intra-articular injection of sodium hyaluronate was performed in 1 group and only arthrocentesis was performed in the other group. Both groups contained patients with disc displacement with reduction and without reduction. Clinical evaluation of the patients was done before the procedure, immediately after the procedure, at 1 week and 1, 3 and 6 months postoperatively. Intensity of TMJ pain was assessed using visual analog scales. Maximal mouth opening and lateral jaw movements also were recorded at each follow-up visit. Both techniques increased maximal mouth opening, lateral movements, and function, while reducing TMJ pain and noise. Although patients benefitted from both techniques, arthrocentesis with injection of SH seemed to be superior to arthrocentesis alone.

    Full Text Available Background/Aim: There is an abundance of data regarding temporomandibular disorders (TMD and bruxism specific to patients with bipolar disorder (BD. This study aimed to investigate the prevalence of TMD signs in subjects with and without BD. Material and Methods: The case group included 242 adult patients (103 men and 139 women with BD and and the control group included 187 subjects without BD (89 men and 98 women. The case and control groups were compared for the presence of bruxism and the signs of TMD including muscle and temporomandibular joint (TMJ tenderness to palpation, limitation of maximum mouth opening, and TMJ sounds. Results: The frequency of at least one sign of TMD was significantly higher in patients with BD (191 ⁄242, 78.9% than the control group (95 ⁄187, 50.8% (p<0.001. Statistically significant differences were found between the case and control groups in terms of joint pain on palpation (p<0.05, masseter muscle pain on palpation (p<0.01, joint clicks (p<0.001 and limited mouth opening (p<0.001. Bruxism was significantly higher in patients with BD (49.6% than the control group (19.8% (p<0.001. Conclusions: Patients with BD appear to be more prone to having TMD signs and bruxism compared to the control group, but this comorbidity should be better understood by further studies.

    To evaluate the diagnostic validity of clinical examination protocols compared with magnetic resonance imaging (MRI) in adults with temporomandibular joint disk displacement disorders. According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review was undertaken using a selection process in 2 phases; 283 different references were identified, and 10 articles were included for qualitative analysis and 7 for meta-analysis. Temporomandibular joint disorders were assessed through clinical diagnosis protocols with the aid of Research Diagnostic Criteria for Temporomandibular Disorders, Diagnostic Criteria for Temporomandibular Disorders, or Clinical Diagnostic Criteria for Temporomandibular Disorders. The authors searched the following electronic databases: Cochrane, LILACS, PubMed, Science Direct, SCOPUS, and Web of Science. Additional search of gray literature was performed. Selected studies were evaluated by using the Quality Assessment Tool for Diagnostic Accuracy Studies-2. Two subgroups were analyzed: Disk displacement with reduction (DDwR) and disk displacement without reduction (DDwoR). The validity of clinical protocols compared with MRI performed in studies evaluating only DDwR presented sensitivity of 44% (39%-49%) and specificity 51% (46%-57%). In studies evaluating only DDwoR, sensitivity was 22% (16%-30%) and specificity 93% (85%-98%). The area under the curve value for validity of clinical protocols in all studies was 0.63, 0.56 for studies evaluating DDwR and 0.64 for studies evaluating DDwoR. Area under the curve values were considered poor. Clinical examination protocols have poor validity to diagnose DDwR and DDwoR compared with MRI. MRI should be used to increase the diagnostic accuracy when the information provided can influence clinical decisions. Copyright © 2016 Elsevier Inc. All rights reserved.

  16. Sensory processing disorders – diagnostic and therapeutic controversies

    Directory of Open Access Journals (Sweden)

    Aneta R. Borkowska

    2017-09-01

    Full Text Available This article presents the current state of knowledge regarding the controversial issue of sensory integration dysfunction/sensory processing disorder. Symptoms are defined as impairments in the accurate reception and registering of stimuli, differentiation of stimulus intensity, and adequate reactivity to stimulation. They can be of specific character and occur in isolation and can also be a nonspecific element of a clinical picture of another disease entity. Psychophysiological and neuroimaging studies confirm the existence of both a distinct group of children with symptoms of sensory processing disorder diagnosed based on descriptions of behaviours listed in questionnaires and of a specific neurobiological basis of this disorder. In clinical practice, it is of key importance to determine whether behavioural problems observed in children are caused by disorders other than sensory processing disorders. Results of meta-analyses regarding sensory integration therapy are inconclusive and do not allow this form of treatment to be considered fact-based. Future studies with high methodological standards are necessary in order to verify the effectiveness of different forms of sensory integration therapy. Parents should be informed about the existing limitations.

    Temporomandibular disorders (TMDs) following motor vehicle collisions (MVCs) may result from direct orofacial trauma but also occur in patients with whiplash-associated disorder (WAD) without such trauma. TMDs may not be identified at the time of first assessment, but may develop weeks or more after the MVC. TMDs in WAD appear to occur predominantly in females and can be associated with regional or widespread pain. TMDs following MVCs may respond poorly to independent therapy and may be best managed using multidisciplinary approaches.

    The present study was conducted to investigate the relationship between magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) and clinical findings of patients having symptoms of temporomandibular disorders, and to consider the possibility to grasp the internal derangement of the TMJ from clinical findings. Subjects were 80 patients who visited to ask orthodontic treatment 16 males and 64 females. The average age was 22 years and 4 months. We performed a investigation of both their previous and present illness. In addition, to decide the correct condition concerning the internal derangement of the TMJ, patients were given MRI examinations (G. E. medical system Signa 1.5 Tesla) before orthodontic treatment. Results were as follows: The three symptoms of temporomandibular disorders-noise, pain, and abnormal mandibular movement, were not related to constant disk displacement. It seemed difficult to infer and obtain the diagnosis of the condition of internal derangement of the TMJ only from clinical findings. In a dental clinics having no medical imaging instrument such as MRI, it was, however, considered that the following items will make it possible to define the condition of internal derangements of the TMJ from clinical findings. As to respects concerning clinical findings, it is necessary to consider the previous illness as well as present illness. TMJ noise indicates a higher relationship to the disk displacement in MRI findings. The temporomandibular joint with plural symptoms indicated a higher incidence of disk displacement examined by MR Imaging than that with a single symptom. (author).

    Temporomandibular disorders and orofacial pain (TMD/OFP) conditions are challenging to diagnose for predoctoral dental students due to the multifactorial etiology, complexity, and controversial issues surrounding these conditions. The aim of this study was to determine if patients in the clinic of one U.S. dental school reported existing signs and symptoms of TMD/OFP, whether the dental students diagnosed the condition based on the reported signs and symptoms, and if the condition was then treated. The study was based on a retrospective analysis of electronic health record data over a three-year period. The results showed that, during the study period, 21,352 patients were treated by student providers. Of those patients, 5.33% reported signs or symptoms associated with TMD/OFP; 5.99% received a TMD/OFP diagnosis; and 0.26% received at least one form of TMD/OFP treatment that had either a diagnosis or signs/symptoms of TMD/OFP. In addition, a small percentage (0.24%) of patients with no documented diagnosis received some sort of TMD/OFP-related treatment. A randomly selected sample of 90 patient charts found that no diagnoses of TMD/OFP were recorded in any of them. The results suggested that students had only marginally diagnosed the problems. Training for students including comprehensive didactic courses and clinical experiences to gain knowledge, context, and skill may be required to ensure they reach the required level of competence and prepare them to face the diagnostic challenges of TMD/OFP after graduation.

    Since its introduction in the 1980s, magnetic resonance imaging has become the preferred method for diagnosing soft tissue abnormalities of temporomandibular joint (TMJ). MR imaging is non-invasive and more accurate than arthorography. In addition, it requires less operator skill and is well tolerated by patients. We are usually taking MR images of the TMJ with the fast spin echo technique that can simultaneously obtain both T2-weighted and proton density images. The purpose of this study was to determine the utility of T2-weighed and proton density images for diagnosing the disk status in TMJ, comparing the results with those obtained by T1-weighted images. We studied 104 TMJs in 52 patients with both T2-weighted and proton density images, and 80 TMJs in 40 patients with only T1-weighted images. The joints were evaluated by two oral radiologists who looked at three aspects of the joints-disk displacement, disk reduction and disk shape - giving ratings of good'' or ''fair'' in each category. Ratings of ''good'' were significant higher in all three categories in T2-weighted and proton density images than in T1-weighted images (p<0.01). Based on these results, we conclude that T2-weighted and proton density images taken with the fast spin echo technique are useful for diagnosing the disk status of the TMJ. (author)

    2017-01-01

    The objective of this literature review was to assess the effect of orthognathic surgical treatment on temporomandibular disorders (TMD), quality of life (QoL), and psychosocial wellness. Journal articles and systematic reviews published in English between 1982 and 2015 were searched using PubMed, MEDLINE, and Cochrane database using the search terms "orthognathic," "temporomandibular disorders," "quality of life," and "psychosocial." The articles were then reviewed and discussed. Both objective and subjective parameters play a role in orthognathic treatment outcome satisfaction and QoL. Psychological factors and TMD exerted a stronger influence on patients' QoL more than objective treatment outcome measures. A paradigm shift in clinical mindset from solely objective measures to a more holistic, patient-centric approach of addressing patients' expectations and improving QoL is warranted when treating patients with dentofacial disharmonies.

    The aims of the present study were to determine the prevalence of temporomandibular disorder (TMD) in a sample of patients with Parkinson's disease (PD) and to analyze the distribution of occlusal contacts. The sample was composed of patients with PD aged 50-75 years. Temporomandibular disorder was evaluated using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The distribution of occlusal contacts was determined using the portable T-Scan III® occlusal analysis system during maximum voluntary clenching. Fisher's exact test was used to test the association between TMD and occlusal contact symmetry. Forty-two individuals with PD were analyzed. The prevalence of TMD was 23.8%. No statistically significant association was found between TMD and occlusal contact symmetry. Moreover, no significant difference in the distribution of occlusal contacts was found between the groups with and without TMD. The present data suggest no association between TMD and occlusal contact asymmetry in individuals with PD. The results of this study identified a prevalence of 23.8% of TMD signs in subjects with PD and a high frequency of occlusal asymmetry in this sample.

    [Purpose] Smartphones are widely used by teenagers and adults for various purposes. As teenagers use smartphones more actively than adults, they are more prone to be addicted to smartphones. Furthermore, excessive usage of smartphones can lead to various psychosocial and physical symptoms. [Subjects and Methods] One hundred teenage subjects were recruited and divided into normal and addiction groups, based on the criteria of the smartphone addiction scale-short version questionnaire. Craniocervical posture and mobility were examined by lateral cephalometric analysis and a cervical range of motion instrument. [Results] Cephalometric analysis showed no significant difference in the craniocervical angles of the resting positions of the two groups. However, measurement using an inclinometer revealed a significantly flexed cervical posture while using smartphones and decreased cervical range of motion in the smartphone-addicted teenagers. The clinical profile of temporomandibular disorders revealed that muscular problems were more frequently presented in the smartphone-addicted teenagers. [Conclusion] These findings suggest that smartphone addiction has a negative influence on craniocervical posture and mobility. Further, it can be postulated that smartphone addiction among teenagers may have contributed to the occurrence of myogenous temporomandibular disorders. In conclusion, smartphone-addicted teenagers may be more frequently subjected to muscular disturbance in the craniocervical area, which probably affects the pathologic process of temporomandibular disorders in teenagers.

    To identify signs of temporomandibular disorders and cervical pain in individuals with episodic and chronic (transformed) migraine (CM), relative to controls without headaches. In this prospective, controlled, double-blind study, we examined 93 individuals divided in 3 groups: episodic migraine EM, (n=31), CM chronic migraine (n=34), and controls without migraine (n=28). We recorded signs of temporomandibular disorders, and of pain in the neck, after the protocol of Helkimo (1974). We calculated the odds ratio (OR) and confidence intervals (CI) of symptoms as a function of headache status. Data from all groups were paired and compared using the chi test. The level of significance was 5% in 2-tailed tests. Relative to controls, participants with EM and CM were significantly more likely to have tenderness in the masticatory muscles [controls=28%, migraine=54%, (OR=3.0, 95% CI=1.1-8.9), CM=73% (OR=6.9, 95% CI=2.3-21.2)], and in the temporomandibular joint [controls=25%, migraine=61%, (OR=4.7, 95% CI=1.5-14.5), CM=61% (OR=4.8, 95% CI=1.6-14.5)]. They were numerically (but nonsignificantly) more likely to have limited lateral jaw movements (CM=34%; EM=26%; NP=18%), joint sounds (CM=44%; EM=29%; NP=28%), and tenderness in neck muscles (CM=64%; EM=51%; NP=35%). In a tertiary care population, individuals with EM and CM are more likely to have tenderness at the temporomandibular joint and on the masticatory muscles, relative to controls. Studies are needed to investigate whether treatment of 1 disorder will improve the other.

    Temporomandibular disorder and mastication. To compare subjects who present temporomandibular disorders to a control group considering mastication and to analyze the related variables. 20 subjects with temporomandibular disorder (TMD group) and 10 controls--selection based on clinical examination and anamnesis--responded to a questionnaire on the self-perception of pain severity and presence of noise in the temporomandibular joints, muscle pain, otologic symptoms, headaches, and jaw opening difficulties. The subjects were also submitted to a clinical examination regarding the number of teeth and functional occlusion--measurements of jaw opening and jaw lateral excursions, occlusal interferences, occlusal contacts of the working and non-working-side, and mastication evaluation. Mastication was evaluated in terms of time needed to eat a stuffed cookie, number of chewing strokes and type (unilateral or bilateral). The maximum force needed at first to break the cookie, verified with a TA-XT2 Texture Analyzer (Stable Micro Systems), was of 4341.8 g. The groups were compared using variance analysis and the correlations between variables were calculated using the Pearson product-moment test. Most of the control subjects presented bilateral pattern of mastication, whereas the TMD group tended to present the unilateral pattern. Masticatory type scores and laterality measurements were significantly higher in the control group. The TMD group presented higher means in terms of: age, time of chewing, number of chewing strokes and TMD severity. Chewing time and type were positively correlated with TMD severity and negatively correlated with number of occlusal interferences. In the TMD group, chewing differed from the normal physiological standard. The number of occlusal interferences and the severity of TMD were variables correlated to chewing.

    Using magnetic resonance imaging (MRI), this study aimed to evaluate the morphology of the articular disc of the temporomandibular joint (TMJ) in patients with temporomandibular disorder (TMD). There were 218 TMJ of 109 assessed patients; 88 were females and 21 males, and all were diagnosed as symptomatic for temporomandibular disorder. The articular disc positions were classified in the normal position and with anterior disc displacement with and without reduction. Regarding the morphology, the discs were classified as follows: biconcave (normal), biplanar, rounded, biconvex, folded, thickening in the posterior band, thickening in the anterior band and hemiconvex. The results indicated that females were the most affected by morphological changes of the articular disc (p = 0.008/Cramer's V = 0.295). There was no statistical significance when correlating the disc morphology with the sides (right and left). There was a significant correlation between the position and morphology of the articular disc (p < 0.001/Cramer's V = 0.609), and in the normal position of the discs presenting biplanar and biconcave morphologies. In TMJ with anterior displacement of the disc with reduction (ADDR), there was a greater correlation with rounded, hemiconvex and biconvex morphologies. Already in the TMJ with displacement without reduction (ADDWR), there was a higher prevalence of folded discs. It can be concluded that morphological changes in the disc are influenced by the type of displacement, and more serious deformations are associated with ADDWR cases.

The proportion of patients who had undergone extractions of wisdom teeth was higher in the case group than in the control group. The difference was statistically significant when patients had undergone extraction of all four wisdom teeth or when the extraction of four wisdom teeth underwent in one sitting or under general anesthesia. The study of patients in case sample shows that all signs of TMD were more common in patients who had undergone extractions in several sessions and under local anesthesia. The temporomandibular joint sounds are significantly more frequent with local anesthesia. In the case group, 85 to 92% of patients have parafunctions and 5 to 11% have malocclusion. This demonstrates the multifactorial etiology of temporomandibular disorders. © EDP Sciences, SFODF, 2015.

    This study was performed to compare the condylar position in patients with temporomandibular joint disorders (TMDs) and a normal group by using cone-beam computed tomography (CBCT). In the TMD group, 25 patients (5 men and 20 women) were randomly selected among the ones suffering from TMD according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The control group consisted of 25 patients (8 men and 17 women) with normal temporomandibular joints (TMJs) who were referred to the radiology department in order to undergo CBCT scanning for implant treatment in the posterior maxilla. Linear measurements from the superior, anterior, and posterior joint spaces between the condyle and glenoid fossa were made through defined landmarks in the sagittal view. The inclination of articular eminence was also determined. The mean anterior joint space was 2.3 mm in the normal group and 2.8 mm in the TMD group, respectively. The results showed that there was a significant correlation between the superior and posterior joint spaces in both the normal and TMD groups, but it was only in the TMD group that the correlation coefficient among the dimensions of anterior and superior spaces was significant. There was a significant correlation between the inclination of articular eminence and the size of the superior and posterior spaces in the normal group. The average dimension of the anterior joint space was different between the two groups. CBCT could be considered a useful diagnostic imaging modality for TMD patients.

    Full Text Available The loss of anterior teeth leads to extreme psychological trauma, along with functional and esthetic debilitations. Healthy anterior teeth play an important role of protecting the posterior teeth during excursive mandibular movement. Loss of anterior teeth induces posterior interference with extended disocclusion time. Posterior disocclusion is critical to remove the harmful force on the teeth temporomandibular joint and eliminate muscle hypertonicity. Occlusal interference is considered as contributing factor to temporomandibular disorder (TMD symptoms. Prosthesis design should eliminate deleterious tooth contacts. Establishing optimum anterior guidance is a key to establishing harmonious functional occlusion in addition to the correction of the esthetic and phonetic disabilities. This case report explains the steps involved in the rehabilitation of the TMD patient with loss of maxillary anterior teeth.

    Temporomandibular disorders (TMDs) are among the most common maxillofacial complaints and a major cause of orofacial pain. Although current treatments provide short- and long-term relief, alternative tissue engineering solutions are in great demand. Particularly, the development of strategies, providing long-term resolution of TMD to help patients regain normal function, is a high priority. An absolute prerequisite of tissue engineering is to understand normal structure and function. The current knowledge of anatomical, mechanical, and biochemical characteristics of the temporomandibular joint (TMJ) and associated tissues will be discussed, followed by a brief description of current TMD treatments. The main focus is on recent tissue engineering developments for regenerating TMJ tissue components, with or without a scaffold. The expectation for effectively managing TMD is that tissue engineering will produce biomimetic TMJ tissues that recapitulate the normal structure and function of the TMJ.

    To estimate the incidence of disc displacement, disc deformity, and bone changes of the temporomandibular joint in elderly patients with temporomandibular disorders, 55 elderly patients (110 joints) were examined by magnetic resonance imaging. The ages of the patients ranged from 65 to 89 years (average, 70 years). They consisted of 13 men and 42 women. Normal disc position was found in 40 joints (36.4%), anterior disc displacement with reduction in 17 joints (15.5%), and anterior disc displacement without reduction in 53 joints (48.2%) on magnetic resonance imaging. Thirty-eight (71.6%) of the 53 joints with anterior disc displacement without reduction had disc deformity and 33 (62.3%) had bone changes. The frequency of bone changes in the elderly group was higher than that in the younger group. Women had a higher incidence of bone changes than men. (author)

    Introduction. The aim of this study was to evaluate the role of auriculotherapy with mustard seeds in the treatment of temporomandibular disorders (TMDs), anxiety, and electromyographic (EMG) activity in university students. Methodology. The State Trait Anxiety Inventory (STAI), Research Diagnostic Criteria (RDC) for TMDs (RDC/TMDs), and electromyography were used in this study of 44 college students with high levels of anxiety and TMDs. The subjects were divided into two groups: an auriculotherapy (AA) group (n = 31) and an AA sham group (n = 13). The mustard seeds were applied to the shenmen, rim, sympathetic, brain stem, and temporomandibular joint (TMJ) points in the AA group and to sham points in the external ear and wrist in the AA sham group. The treatment protocol was 10 sessions (two treatments per week). Results. Anxiety (p Auriculotherapy was effective in the treatment of students with anxiety and TMDs.

    To determine the construct validity of algometry and to compare it with that of palpation, and to compare tenderness of masticatory muscle sites and the temporomandibular joint (TMJ) on palpation and on algometry. Two hundred fifty subjects, 148 with temporomandibular disorder (TMD) pain complaints, underwent a standardized blinded physical examination that included pain-intensity measures on palpation and pressure pain threshold measures on algometry of masseter muscle sites, temporalis muscle sites, and the TMJ. Logistic regression analysis indicated that the recognition of TMD pain complaints based on pressure algometry was comparable to that of palpation (R2 = 0.22 and R2 = 0.21, respectively). The masseter muscles were most tender to palpation and algometry, followed by the TMJs and the temporalis muscles. Construct validity of algometry in the recognition of TMD pain complaints is comparable to that of palpation, and differences in tenderness on palpation and on algometry are found between masticatory muscle sites and the TMJ.

    This study assessed the interexaminer reliability and validity of palpation (PA) and pressure pain threshold (PPT) of the temporomandibular joint (TMJ) and the masseter and temporalis muscles in patients with temporomandibular disorders (TMD) and asymptomatic controls. Eighty (80) subjects were distributed into two groups: Group 1 consisted of 40 TMD patients with muscular and joint pain selected by RDC/TMD Axis I; and Group 2 (control) with 40 asymptomatic individuals. Training and calibration of examiners was undertaken prior to testing. Mean reliability values were 0.64 and 0.78 (PPT), and 0.59 and 0.75 (PA), for patients and controls, respectively. Results showed statistically significant differences (p<0.001), for PA and PPT among TMD patients compared with the control. The results also showed acceptable specificity values (above 0.90), although sensitivity had low values. The tests had low diagnostic validity to discriminate between patients and controls, with low positive predictive values (PPV).

    This study investigated the relation between magnetic resonance imaging (MRI) findings and occlusal condition of the intercuspal position in temporomandibular disorders (TMD) patients. Thirty TMD patients, and 29 control subjects, were selected for this study. Occlusal contracts and occlusal bite force in the intercuspal position were determined with occlusal registration strips, black silicon (bite checker), and Dental Prescale 50 H type R (pressure sensitive sheet), respectively. The subjects were divided into three groups based on MRI assessments: disk displacement with reduction (DDWR), disk displacement without reduction (DDWOR), and normal subjects. The number of teeth with occlusal contract in the intercuspal position of the DDWOR TMD patients group was lower than in the normal control group. The number of teeth with occlusal contact on the anterior teeth showed a similar tendency. The total occlusal bite force in the intercuspal position in the DDWOR TMD patients group was lower than in the DDWR control group and the normal control group. The occlusal bite force on anterior teeth in the intercuspal position showed a similar tendency. The ratio between anterior teeth and molars occlusal bite force in the intercuspal position in the DDWOR TMD patients group was lower than in the normal control group. There is some relation between MRI findings and occlusal condition of the intercuspal position in TMD patients. (author)

    In this executive summary, the authors describe a protocol for assessing patients with temporomandibular disorder (TMD). It is based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for clinical and research applications. The DC/TMD was developed using published Axis I physical diagnoses for the most common TMDs. Axis I diagnostic criteria were derived from pertinent clinical TMD signs and symptoms. Axis II consists of psychosocial and behavioral questionnaires already in the public domain. A panel of experts vetted and modified the Axis I and Axis II diagnostic protocols. Recommended changes were assessed for diagnostic accuracy by using the Validation Project's data set, which formed the basis for the development of the DC/TMD. Axis I diagnostic criteria for TMD pain-related disorders have acceptable validity and provide definitive diagnoses for pain involving the temporomandibular joint (TMJ) and masticatory muscles. Axis I diagnostic criteria for the most common TMJ intra-articular disorders are appropriate for screening purposes only. A definitive diagnosis for TMJ intra-articular disorders requires computed tomography or magnetic resonance imaging. Axis II questionnaires provide valid assessment of psychosocial and behavioral factors that can affect management of TMD. The DC/TMD provides a questionnaire for the pain history in conjunction with validated clinical examination criteria for diagnosing the most common TMDs. In addition, it provides Axis II questionnaires for assessing psychosocial and behavioral factors that may contribute to the onset and perpetuation of the patient's TMD. The DC/TMD is appropriate for use in clinical and research settings to allow for a comprehensive assessment of patients with TMD. Copyright © 2016 American Dental Association.

    The aim of this study was to associate minor psychiatric disorders (general health) and quality of life with temporomandibular disorders (TMD) in patients diagnosed with different TMD classifications and subclassifications with varying levels of severity. Among 150 patients reporting TMD symptoms, 43 were included in the present study. Fonseca's anamnestic index was used for initial screening while axis I of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC-TMD) was used for TMD diagnosis (muscle-related, joint-related or muscle and joint-related). Minor psychiatric disorders were evaluated through the General Health Questionnaire (GHQ) and quality of life was assessed using the World Health Organization Quality Of Life-Brief Version (WHOQOL-BREF). An association was found between minor psychiatric disorders and TMD severity, except for stress. A stronger association was found with mild TMD. Considering TMD classifications and severity together, only the item "death wish" from the GHQ was related to severe muscle-related TMD (p = 0.049). For quality of life, an association was found between disc displacement with reduction and social domain (p = 0.01). Physical domains were associated with TMD classifications and severity and the association was stronger for muscle and joint-related TMD (p = 0.37) and mild TMD (p = 0.042). It was concluded that patients with TMD require multiple focuses of attention since psychological indicators of general health and quality of life are likely associated with dysfunction.

    The etiology of temporomandibular disorders (TMD), which are considered as a heterogeneous group of psychophysiological disturbances, remains a controversial issue in clinical dentistry. This study aimed to evaluate whether the salivary alpha-amylase (sAA), cortisol levels, and anxiety symptoms differ between children with and without TMD. Initially, 316 young subjects were screened in public schools (nonreferred sample); 76 subjects aged 7-14 years were selected and comprised the TMD and control groups with 38 subjects each matched by sex, age, and the presence/absence of sleep bruxism. Four saliva samples were collected: upon waking, 30 min and 1 h after awakening (fasting), and at night (at 8 PM) on 2 alternate days to examine the diurnal profiles of cortisol and sAA. Anxiety symptoms were screened using the Multidimensional Anxiety Scale for Children (MASC-Brazilian version). Shapiro-Wilk test, Student's t-test/Mann-Whitney U test, and correlation tests were used for data analysis. No significant differences were observed in the salivary cortisol area under the curve (AUCG mean ± SD = 90.22 ± 63.36 × 94.21 ± 63.13 µg/dL/min) and sAA AUCG (mean ± SD = 2544.52 ± 2142.00 × 2054.03 ± 1046.89 U/mL/min) between the TMD and control groups, respectively (p > 0.05); however, the clinical groups differed in social anxiety domain (t = 3.759; CI = 2.609, 8.496), separation/panic (t = 2.243; CI = 0.309, 5.217), physical symptoms (U = 433.500), and MASC total score (t = -3.527; CI = -23.062, -6.412), with a power of the test >80% and large effect size (d = 0.80), with no significant correlation between the MASC total score, cortisol, and sAA levels. Although children with TMD scored higher in anxiety symptoms, no difference was observed in the salivary stress biomarkers between children with and without TMD.

    There is still controversy about whether orthognathic surgery negatively or positively affects temporomandibular disorders (TMDs). The purpose of this study was to determine whether orthognathic surgery has a beneficial or deleterious effect on pre-existing TMDs. A systematic review and meta-analysis were conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched 3 major databases to locate all pertinent articles published from 1980 to March 2016. All subjects in the various studies were stratified a priori into 9 categories based on subdiagnoses of TMDs. The predictor variables were those patients with pre-existing TMDs who underwent orthognathic surgery in various subgroups. The outcome variables were maximal mouth opening and signs and symptoms of a TMD before and after orthognathic surgery based on the type of osteotomy. The meta-analysis was performed using Comprehensive Meta-Analysis software (Biostat, Englewood, NJ). A total of 5,029 patients enrolled in 29 studies were included in this meta-analysis. There was a significant reduction in TMDs in patients with a retrognathic mandible after bilateral sagittal split osteotomy (BSSO) (P = .014), but no significant difference after bimaxillary surgery (BSSO and Le Fort I osteotomy) (P = .336). There was a significant difference in patients with prognathism after isolated BSSO or intraoral vertical ramus osteotomy and after combined BSSO and Le Fort I osteotomy (P = .001), but no significant difference after BSSO (P = .424) or bimaxillary surgery (intraoral vertical ramus osteotomy and Le Fort I osteotomy) (P = .728). Orthognathic surgery caused a decrease in TMD symptoms for many patients who had symptoms before surgery, but it created symptoms in a smaller group of patients who were asymptomatic before surgery. The presence of presurgical TMD symptoms or the type of jaw deformity did not identify which patients' TMDs would improve, remain the

    Introduction To evaluate whether the hypothesis that estrogen levels are associated with temporomandibular disorders (TMD) in humans can be confirmed or contradicted by available literature. Material and methods A systematic review based on the content of PubMed, Scopus, and Cochrane Library databases was performed. Studies were identified using a combination of key words ‘temporomandibular disorder’ and ‘estrogen’. Nine studies were included into our review. Results The relationship between estrogen levels and TMD was found in seven out of nine reviewed papers. Results from two papers suggest that a high estrogen level is associated with an increased prevalence of TMD. Five additional papers found a relationship between a low estrogen level and an increase in TMD pain. In considering the value of evidence and inconsistencies of results in the reviewed publications, we state that there is weak evidence to support the hypothesis that estrogen levels are associated with TMD. Conclusions Results of reviewed studies were divergent and sometimes contradictory. One possible explanation is that estrogen influences TMD pain processing differently than temporomandibular joints (TMJ) structures, as shown in many animal studies. Estrogen may influence TMD pain processing differently than TMJ structures. We suggest consideration of the dual action of estrogen when planning future studies on its association with TMD.

    This systematic review aimed to investigate whether intra-articular injections of platelet-rich plasma (PRP) are beneficial for the treatment of degenerative temporomandibular disorders, such as temporomandibular joint osteoarthritis (TMJ-OA) and disc displacement with osteoarthritic lesions, when compared to other treatments, such as injections of hyaluronic acid (HA) or saline. An electronic search of the MEDLINE and Scopus databases was performed using combinations of the terms "temporomandibular" and "platelet rich plasma", to identify studies reported in English and published up until May 2017. A hand-search of relevant journals and the reference lists of selected articles was also performed. The initial screening identified 153 records, of which only six fulfilled the inclusion criteria and were included in this review. Of these studies, three compared PRP with HA, while three compared PRP with Ringer's lactate or saline. Four of the studies found PRP injections to be superior in terms of improvements in mandibular range of motion and pain intensity up to 12 months after treatment, while the remaining two studies found similar results for the different treatments. There is slight evidence for the potential benefits of intra-articular injections of PRP in patients with TMJ-OA. However, a standardized protocol for PRP preparation and application needs to be established. Copyright © 2017 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

    Neck accessory respiratory muscles and mouth breathing suggest a direct relationship among asthma, Temporomandibular (TMD) and Cervical Spine (CSD) Disorders. This study was performed to evaluate and correlate TMD, CSD in asthmatic and non-asthmatic. Thirty asthmatic children (7.1 +/- 2.6 years old), 30 non-asthmatic predominantly mouth breathing children (Mouth Breathing Group - MBG) (8.80 +/- 1.61 years) and 30 non-asthmatic predominantly nasal breathing children (Nasal breathing Group - NBG) (9.00 +/- 1.64 years) participated in this study and they were submitted to clinical index to evaluate stomatognathic and cervical systems. Spearman correlation test and Chi-square were used. The level of significance was set at p temporomandibular joint (TMJ), TMJ sounds, pain during cervical extension and rotation, palpatory tenderness of sternocleidomastoids and paravertabrae muscles and a severe reduction in cervical range of motion were observed in AG. Both AG and MBG groups demonstrated palpatory tenderness of posterior TMJ, medial and lateral pterygoid, and trapezius muscles when compared to NBG. Results showed a positive correlation between the severity of TMD and CSD signs in asthmatic children (r = 0.48). No child was considered normal to CSD and cervical mobility. The possible shortening of neck accessory muscles of respiration and mouth breathing could explain the relationship observed between TMD, CSD signs in asthmatic children and emphasize the importance of the assessment of temporomandibular and cervical spine regions in asthmatic children.

    To carry out a systematic review to assess the evidence concerning the association between head and cervical posture and temporomandibular disorders (TMD). A search of Medline, Pubmed, Embase, Web of Science, Lilacs, and Cochrane Library databases was conducted in all languages with the help of a health sciences librarian. Key words used in the search were posture, head posture, cervical spine or neck, vertebrae, cervical lordosis, craniomandibular disorders or temporomandibular disorders, temporomandibular disorders, and orofacial pain or facial pain. Abstracts which appeared to fulfill the initial selection criteria were selected by consensus. The original articles were retrieved and evaluated to ensure they met the inclusion criteria. A methodological checklist was used to evaluate the quality of the selected articles and their references were hand-searched for possible missing articles. Twelve studies met all inclusion criteria and were analyzed in detail for their methodology and information quality. Nine articles that analyzed the association between head posture and TMD included patients with mixed TMD diagnosis; 1 article differentiated among muscular, articular, and mixed symptomatology; and 3 articles analyzed information from patients with only articular problems. Finally, 2 studies evaluated the association between head posture and TMD in patients with muscular TMD. Several methodological defects were noted in the 12 studies. Since most of the studies included in this systematic review were of poor methodological quality, the findings of the studies should be interpreted with caution. The association between intra-articular and muscular TMD and head and cervical posture is still unclear, and better controlled studies with comprehensive TMD diagnoses, greater sample sizes, and objective posture evaluation are necessary.

    Background There is a need to expand the current temporomandibular disorder (TMD) classification to include less common, but clinically important disorders. The immediate aim was to develop a consensus-based classification system and associated diagnostic criteria that have clinical and research utility for less common TMDs. The long-term aim was to establish a foundation, vis-à-vis this classification system, that will stimulate data collection, validity testing, and further criteria refinement. Methods A working group [members of the International RDC/TMD Consortium Network of the International Association for Dental Research (IADR), members of the Orofacial Pain Special Interest Group (SIG) of the International Association for the Study of Pain (IASP), and members from other professional societies] reviewed disorders for inclusion based on clinical significance, the availability of plausible diagnostic criteria, and the ability to operationalize and study the criteria. The disorders were derived from the literature when possible and based on expert opinion as necessary. The expanded TMD taxonomy was presented for feedback at international meetings. Results Of 56 disorders considered, 37 were included in the expanded taxonomy and were placed into the following four categories: temporomandibular joint disorders, masticatory muscle disorders, headache disorders, and disorders affecting associated structures. Those excluded were extremely uncommon, lacking operationalized diagnostic criteria, not clearly related to TMDs, or not sufficiently distinct from disorders already included within the taxonomy. Conclusions The expanded TMD taxonomy offers an integrated approach to clinical diagnosis and provides a framework for further research to operationalize and test the proposed taxonomy and diagnostic criteria.

    The purpose of this study was to determine the prevalence and the nature of the relationships between 3 temporomandibular joint disease (TMD) symptoms and symptoms of associated structures. This study was designed to rule out the effect from the uneven composition of the samples on TMD symptoms. The samples were collected from subjects who were of the same age, gender, district, and race. Nineteen-year old men (n = 27,978) were selected and investigated by means of questionnaires and clinical examinations. The prevalence of each symptom was studied and tried to determine the effects of the TMD-associated signs on the TMD signs. The indices allocated to reflect the TMD signs and symptoms and the others were dichotomized for bivariate analysis. The predictor variables were headache, neck pain, referred pain, stress, past trauma history in the TMJ, past TMJ dislocation, bruxism, and clenching. The outcome variables were mouth opening limitation, TMJ pain on rest, and TMJ pain during function. The incidence of masticatory muscle stiffness was 17.8%; TMJ sounds, 14.3%; headache, 7.2%; neck pain, 13.5%; bruxism, 8.4%; and clenching, 9.9%. Stress occurred in 12.8%, past trauma history in 11%, and previous joint dislocation in 2.5%. The experience of dislocation in the TMJ was found to be the most important risk factor in terms of mouth opening limitation (odds ratio, 4.08, P stress in terms of mouth opening limitation. Considering referred pain can be induced by TMD, stress may be more related to mouth opening limitation (odds ratio, 2.18, P Stress was related to limitations of mouth opening, and the experience of trauma in the TMJ was found to be related to pain in the joint region. Bruxism may not be a direct risk factor in TMD, and the clenching habit found to be more harmful than bruxism. Copyright 2002 American Association of Oral and Maxillofacial Surgeons

    Temporomandibular joint disorder (TMD) is a broad pain disorder that refers to several conditions affecting the temporomandibular joint of the jaw and the muscles of mastication. As with most pain disorders, a high prevalence of depression and anxiety is associated with TMD. Research has shown that selective serotonin reuptake inhibitors (SSRIs), the first-line drug therapy for major depressive disorder, may not be suitable for TMD patients because SSRIs can induce teeth-grinding, otherwise known as bruxism. This is problematic because bruxism is believed to further exacerbate TMD. Therefore, the purpose of this literature review is to better understand the mechanism of SSRI-induced bruxism, as well as discuss alternative antidepressant options for treating depression and anxiety in patients with bruxism and TMD. Alternative classes of antidepressants reviewed include serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, atypical antidepressants, and monoamine oxidase inhibitors. Findings indicate that dopamine agonists and buspirone are currently the most effective medications to treat the side effects of SSRI-induced bruxism, but results regarding the effectiveness of specific antidepressants that avoid bruxism altogether remain inconclusive.

    Full Text Available OBJETIVO: verificar a presença e possível correlação entre alteração vocal e DTM, em professores, a partir de dados de avaliação autorreferida, fonoaudiológica, otorrinolaringológica e odontológica. MÉTODOS: participaram deste estudo, 29 professores de uma escola de rede pública do ensino fundamental e médio do município de Sorocaba - SP. Os professores responderam questionário para levantamento de alteração vocal, e de disfunção temporomandibular (DTM. Foram realizadas quatro avaliações: perceptivo-auditiva; otorrinolaringológica; motricidade orofacial e odontológica. A menção a três ou mais sintomas no questionário determinou "presença" de queixa de voz e de DTM. As avaliações: perceptivo-auditiva e otorrinolaringológica concluíram a "ausência" e "presença" de alteração de voz e de laringe. Nas avaliações da motricidade orofacial e odontológica foi considerada DTM quando registrados três ou mais sinais e/ou sintomas, sendo indispensável à presença de dor. Na análise estatística dos dados, foram empregados: teste de Igualdade de Duas Proporções, teste exato de Fisher e de concordância Kappa. RESULTADOS: dentre os participantes, 82,8% fizeram autorreferência à alteração vocal e 62,1% de sintomas de DTM; 51,7% apresentaram alteração de voz na avaliação otorrinolaringológica e 65,5%, alteração de DTM na avaliação odontológica. Na comparação da avaliação de alteração de voz e DTM foi registrada correlação significante presente na avaliação perceptivo-auditiva da voz e de motricidade orofacial para DTM, e com tendência a significância na aplicação do questionário. CONCLUSÃO: os resultados apontam na direção de confirmar a presença de alteração de voz e DTM no grupo de professores pesquisado e correlação entre os mesmos.PURPOSE: to check the presence and possible correlation between vocal disorders and temporomandibular joint disorders (TMJD in teachers, from self

    Two principal schools of thought regarding the etiology and optimal treatment of temporomandibular disorders exist; one physical/functional, the other biopsychosocial. This position paper establishes the scientific basis for the physical/functional. THE ICCMO POSITION: Temporomandibular disorders (TMD) comprise a group of musculoskeletal disorders, affecting alterations in the structure and/or function of the temporomandibular joints (TMJ), masticatory muscles, dentition and supporting structures. The initial TMD diagnosis is based on history, clinical examination and imaging, if indicated. Diagnosis is greatly enhanced with physiologic measurement devices, providing objective measurements of the functional status of the masticatory system: TMJs, muscles and dental occlusion. The American Alliance of TMD organizations represent thousands of clinicians involved in the treatment of TMD. The ten basic principles of the Alliance include the following statement: Dental occlusion may have a significant role in TMD; as a cause, precipitant and/or perpetuating factor. Therefore, it can be stated that the overwhelming majority of dentists treating TMD believe dental occlusion plays a major role in predisposition, precipitation and perpetuation. While our membership believes that occlusal treatments most frequently resolve TMD, it is recognized that TMD can be multi faceted and may exist with co-morbid physical or emotional factors that may require therapy by appropriate providers. The International College of Cranio-Mandibular Orthopedics (ICCMO), composed of academic and clinical dentists, believes that TMD has a primary physical/functional basis. Initial conservative and reversible TMD treatment employing a therapeutic neuromuscular orthosis that incorporates relaxed, healthy masticatory muscle function and a stable occlusion is most often successful. This is accomplished using objective measurement technologies and ultra low frequency transcutaneous electrical neural

    To determine the relationship between clinical symptoms and magnetic resonance (MR) images in patients presenting with temporomandibular joint (TMJ) disorders. This study was based on 172 joints in 86 patients presenting with TMJ disorders. Joint pain and sound during jaw opening and closing movements were recorded, and the possible relationship between disc positions and bony changes of the condylar head and the articular fossa in MR images in the oblique sagittal planes were examined. Data were analyzed by Chi-square test. There was no statistically significant relationship between clinical symptoms and MR images in the patients with TMJ disorders. In the patient with TMJ disorders, joint pain and sound could not be specific clinical symptoms that are related with MR image findings, and asymptomatic joint did not necessarily imply that the joints are normal according to MR image findings.

    Full Text Available This article reviews recently published studies investigating the MRI and sonographic diagnosis of masticatory muscle myalgia in temporomandibular disorder patients. The MRI and sonographic features of muscle after treatment are also discussed. Literature published within the last 15 years was obtained from the PubMed database using the following Mesh terms: magnetic resonance imaging (MRI or sonography, masticatory muscle pain, and treatment. MRI and sonography enable accurate visualization and evaluation of the masticatory muscles, thereby increasing our understanding of pathology and cause of pain associated with these muscles. Although therapeutic efficacy is often evaluated based on clinical findings, MR and sonographic imaging studies may also be valuable.

    Articulators have been widely used by clinicians of dentistry. But routine articulator mounting is still controversial in orthodontics. Orthodontists oriented by gnathology approve routine articulator mounting while nongnathologic orthodontists disapprove it. This article reviews the thoughts of orthodontist that they agree or disagree with routine articulator mounting based on the considerations of biting, temporomandibular disorder (TMD), periodontitis, and so on.

    The prevalence of temporomandibular disorders (TMD) is higher in females, reaching their high peak during reproductive years, probably because of the action of some female hormones, which alter pain threshold. This study aimed to investigate the prevalence of TMD in postmenopausal women and its relationship with pain and hormone replacement therapy (HRT). In total, 284 patients were evaluated and classified using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Pain was measured using the Visual Analogue Scale (VAS), and patients were also asked about the use of HRT. All data was analyzed using analysis of variance (ANOVA) and chi-square test. In total, 155 subjects did not have TMD and 129 had TMD; TMD group patients were classified according to RDC/TMD axis I classification as follows: muscle disorder group (1.6%), disk displacement group (72.87%), and arthralgia, osteoarthritis, and osteoarthrosis group (37.98%). Pain was registered in 35 patients who belonged to the TMD group, while 48 patients reported the use of HRT. There was a similar percentage of TMD and non TMD patients; moreover, the use of exogenous hormones was no associated with TMD, suggesting that there is no influence on the pain threshold.

    To evaluate the relationships between gender, diagnosis, and severity of temporomandibular disorders (TMD) with self-reports of the impact of TMD on the quality of life. Eighty-three individuals seeking TMD treatment at the Dental School of Pontifical Catholic University Minas from May to August 2005 were evaluated by a single examiner who was trained and calibrated for diagnosis according to criteria of Axis I of the Research Diagnostic Criteria for TMD (RDC/TMD). The severity of TMD was established by the Temporomandibular Index and the impact on quality of life by the Oral Health Impact Profile (OHIP 14). Complete data were available for 78 of the 83 initial patients and evaluated by the Mann-Whitney test and Spearman correlation analysis. Except for one patient, all individuals showed some impact related to physical pain. Of the seven aspects evaluated on the OHIP 14, women presented a greater impact than men only for functional limitations (Mann-Whitney, P disorders (group I) or osteoarthritis (group III) reported a greater impact than those without (P quality of life and severity of TMD (P quality of life of individuals with TMD, without group difference between genders. The presence of muscular disorders (group I) and osteoarthritis (group III) was related to greater impact on quality of life, which was not observed for diagnoses of disc displacement (group II). A correlation between severity of TMD and impact on quality of life was clearly observed.

    To determine whether there was a difference in maximal cervical flexor muscle strength in subjects with temporomandibular disorders (mixed and myogenous) compared with healthy subjects. Cross-sectional study. Orthopedics/sports laboratory at the University of Alberta. Subjects (N=149) of whom 50 were healthy, 54 had myogenous temporomandibular disorders (TMD), and 45 had mixed TMD. Not applicable. Maximal cervical flexor strength, pain. There was no statistically significant difference in maximal cervical flexor strength among groups (P>.05). Subjects' body weight was significantly associated with strength. No significant association between jaw disability with maximal cervical flexor strength was found. A significant but weak association between neck disability and maximal cervical flexors strength was found. These results indicated that strength evaluation is one of several assessment factors that need to be addressed when evaluating musculoskeletal painful conditions such as TMD and neck disorders, but strength evaluation cannot be considered as a direct measure of disability. Future studies should explore evaluation of strength in other muscular groups such as cervical extensors, rotators, and lateral flexors, and also under different conditions such as rapid movements, and in patients with more severe jaw disability.

    Full Text Available INTRODUCTION: Temporomandibular disorders (TMD present several signs and symptoms that hinder their correct diagnosis, which is imperative on the elaboration of a treatment plan. Over the past years, several studies have been conducted to characterize and classify TMD to better understand these disorders. Therefore, the purpose of this study was to assess the electromyographic behavior of the masseter and temporal muscles in individuals with and without myogenic, arthrogenic and mixed TMD. METHOD: Forty volunteers of both genders responded to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC-TMD Questionnaire, were submitted to clinical exam and underwent bilateral electromyographic exam of the masseter and temporal muscles. RESULTS: No statistically significant difference (p>0.05 was observed during the assessment of isotonic contraction. Regarding isometric contraction, pairing between the mixed TMD group and the asymptomatic subjects did not present significant difference (p>0.05. Comparison between the myogenic and arthrogenic TMD groups and the asymptomatic group showed statistically significant difference (p<0.05. The findings of the present study demonstrated alteration on the muscle contraction pattern of TMD individuals compared to that of asymptomatic patients.

    The present article aimed to review systematically the literature on the relation between facial skeletal structures and temporomandibular joint (TMJ) disorders. A systematic search in the dental and medical literature was performed to identify all studies of humans assessing the relation between TMJ disorders and facial morphology. Articles were included based on study design, irrespective of TMJ disorder (eg, disc displacement, osteoarthrosis, or unspecified), skeletal features, diagnostic strategies (e.g., imaging techniques or clinical assessment), and population (eg, demographic features of participants) under investigation. The selected articles were assessed according to a format based on patients, problem, and population, intervention, comparison, and outcome and quality was evaluated based on the Newcastle-Ottawa Scale. Thirty-four articles were included in the review, 27 of which concerned adult samples and 7 concerned adolescent samples. Quality was generally moderate. The articles dealt with the relation between facial morphology and the following TMJ disorders, assessed clinically or by magnetic resonance (MR): disc displacement (n = 20), osteoarthritis or osteoarthrosis (n = 8), and temporomandibular disorder signs and symptoms (n = 6). The different approaches featuring the various investigations and the presence of some potential methodologic biases complicated a summary of the findings. Most studies reported that some features related to the vertical dimension of the face might help distinguish patients with potential TMJ disc displacement or MR-detected signs of osteoarthrosis from those without TMJ disorders. The quality of the available literature is not adequate to provide an evidence base on the topic. Despite the heterogeneity of design and findings of the reviewed articles, it seems reasonable to suggest that skeletal Class II profiles and hyperdivergent growth patterns are likely associated with an increased frequency of TMJ disc

    The Ehlers-Danlos syndrome, hypermobility type (EDS-HT) is a rare genetic disease. Diagnosis is based on a combination of clinical criteria described in the classification of Villefranche. Diagnosis is difficult to make because of the lack of specific clinical signs and the absence of genetic testing. The EDS-TH manifests itself manly by musculoskeletal pain and joint hypermobility. Temporomandibular disorders (TMD) are also reported. Our aim was to objectify the presence and to qualify the type of TMD associated with the EDS-HT in order to propose an additional diagnostic argument. A prospective, monocenter case-control study, comparing a cohort of patients suffering from EDS-HT to a paired control group of healthy volunteers has been conducted. Clinical examination was standardized, including a general questioning, an oral examination and a temporomandibular joint examination following the TMD/RDC (temporomandibular disorders/research diagnostic criteria). Fourteen EDS-HT patients and 58 control patients were examined. The prevalence of TMDs (n=13; 92.9% vs. n=4; 6.9%; P=10(-11)) was significantly higher in the EDS-HT group. TMDs occurring in the EDS-HT group were complex, combining several mechanisms in contrast to the control group, where only one mechanism was found in all the patients (n=13; 92.9% vs. n=0; 0.0%). TMDs are strongly associated with RDS-HT. TMDs could therefore be used in the diagnosis of this disease. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The influence of the neuromuscular system on the cervical region and mastication is directly associated with mandibular movements and neck posture. Normal occlusal homeostasis depends on complex sensory feedback mechanisms of the periodontal ligament, temporomandibular joint and other structures of the stomatognathic system. This feedback serves as a regulatory mechanism that helps determine the force and nature of muscle contractions. Alterations in the muscles of mastication, neck muscles, and occlusal characteristics constitute causal factors of imbalances in the postural muscle chains, leading to alterations in the center of pressure (CoP) of the feet. Thus, therapies that seek occlusal reestablishment, such as muscle relaxation techniques, may lead to a restructuring of the global equilibrium of the neuromuscular system and an improvement in body posture. The aim of the present pilot study was to investigate the immediate effect of facial massage on the CoP in the anteroposterior (CoPAP) and mediolateral (CoPML) directions in individuals with temporomandibular disorder (TMD). Twenty individuals with a diagnosis of TMD based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were submitted to a facial massage technique. CoPAP and CoPML were evaluated using a force plate. Evaluations were performed under two visual conditions (eyes open and eyes closed) prior to resting in dorsal decubitus (baseline), after 10 minutes of rest (premassage) and after the administration of the massage technique (postmassage). No significant differences were found regarding CoPAP velocity with eyes open or the following aspects under either visual condition (eyes open or closed): CoPML velocity, RMS of CoPAP, RMS of CoPML, and sway area. The only significant difference was found for mean CoPAP velocity with eyes closed. While the results of the present study demonstrate the reliability of the reproduction of the data, facial massage had no immediate

    Clinical tests used to examine patients with temporomandibular disorders vary in methodological quality, and some are not tested for reliability. The purpose of this cross-sectional study was to evaluate inter-tester reliability of clinical tests and a cluster of tests used to examine patients with long-lasting temporomandibular disorders. Forty patients with pain in the temporomandibular area treated by health-professionals were included. They were between 18-70 years, had 65 symptomatic (33 right/32 left) and 15 asymptomatic joints. Two manual therapists examined all participants with selected tests. Percentage agreement and the kappa coefficient ( k ) with 95% confidence interval (CI) were used to evaluate the tests with categorical outcomes. For tests with continuous outcomes, the relative inter-tester reliability was assessed by the intraclass-correlation-coefficient (ICC 3,1 , 95% CI) and the absolute reliability was calculated by the smallest detectable change (SDC). The best reliability among single tests was found for the dental stick test, the joint-sound test ( k  = 0.80-1.0) and range of mouth-opening (ICC 3,1 (95% CI) = 0.97 (0.95-0.98) and SDC = 4 mm). The reliability of cluster of tests was excellent with both four and five positive tests out of seven. The reliability was good to excellent for the clinical tests and the cluster of tests when performed by experienced therapists. The tests are feasible for use in the clinical setting. They require no advanced equipment and are easy to perform.

    The purpose of this study was to complete a systematic review of manual and manipulative therapy (MMT) for common upper extremity pain and disorders including the temporomandibular joint (TMJ). A literature search was conducted using the Cumulative Index of Nursing Allied Health Literature, PubMed, Manual, Alternative, and Natural Therapy Index System (MANTIS), Physiotherapy Evidence Database (PEDro), Index to Chiropractic Literature, Google Scholar, and hand search inclusive of literature from January 1983 to March 5, 2012. Search limits included the English language and human studies along with MeSH terms such as manipulation, chiropractic, osteopathic, orthopedic, and physical therapies. Inclusion criteria required an extremity peripheral diagnosis (for upper extremity problems including the elbow, wrist, hand, finger and the (upper quadrant) temporomandibular joint) and MMT with or without multimodal therapy. Studies were assessed using the PEDro scale in conjunction with modified guidelines and systems. After synthesis and considered judgment scoring was complete, evidence grades of "A, B, C and I" were applied. Out of 764 citations reviewed, 129 studies were deemed possibly to probably useful and/or relevant to develop expert consensus. Out of 81 randomized controlled or clinical trials, 35 were included. Five controlled or clinical trials were located and 4 were included. Fifty case series, reports and/or single-group pre-test post-test prospective case series were located with 32 included. There is Fair (B) level of evidence for MMT to specific joints and the full kinetic chain combined generally with exercise and/or multimodal therapy for lateral epicondylopathy, carpal tunnel syndrome, and temporomandibular joint disorders, in the short term. The information from this study will help guide practitioners in the use of MMT, soft tissue technique, exercise, and/or multimodal therapy for the treatment of a variety of upper extremity complaints in the context

    Full Text Available OBJECTIVE: The objective of this study was to review the most recent studies from the last 15 years, in search of clinical studies that report the relationship between TMD and orthodontic treatment and/or malocclusion. Our intention was to determine whether orthodontic treatment would increase the incidence of signs and symptoms of TMD, and whether orthodontic treatment would be recommended for treating or preventing signs and symptoms of TMD. METHODS: Literature reviews, editorials, letters to the editor, experimental studies in animals and short communications were excluded from this review. Were included only prospective, longitudinal, case-control or retrospective studies with a large sample and significant statistical analysis. Studies that dealt with craniofacial deformities and syndromes or orthognathic surgery treatment were also excluded, as well as those that reported only the association between malocclusion and TMD. RESULTS: There were 20 articles relating orthodontics to TMD according to the inclusion criteria. The studies that associated signs and symptoms of TMD to orthodontic treatment showed discrepant results. Some have found positive effects of orthodontic treatment on signs and symptoms of TMD, however, none showed a statistically significant difference. CONCLUSIONS: All studies cited in this literature review reported that orthodontic treatment did not provide risk to the development of signs and symptoms of TMD, regardless of the technique used for treatment, the extraction or non-extraction of premolars and the type of malocclusion previously presented by the patient. Some studies with long-term follow-up concluded that orthodontic treatment would not be preventive or a treatment option for TMD.OBJETIVO: revisar a literatura mais atual, dos últimos 15 anos, em busca de estudos clínicos que relatem a relação entre a disfunção temporomandibular (DTM e o tratamento ortodôntico e/ou a má oclusão.

    To describe CT findings in dogs and cats with temporomandibular joint (TMJ) disorders. Retrospective case series. 41 dogs and 17 cats. Medical records and CT images of the skull were reviewed for dogs and cats that were examined at a dentistry and oral surgery specialty practice between 2006 and 2011. Of 142 dogs and 42 cats evaluated, 41 dogs and 17 cats had CT findings consistent with a TMJ disorder. In dogs, the most common TMJ disorder was osteoarthritis; however, in most cases, there were other TMJ disorders present in addition to osteoarthritis. Osteoarthritis was more frequently identified at the medial aspect rather than the lateral aspect of the TMJ, whereas the frequency of osteoarthritic involvement of the dorsal and ventral compartments did not differ significantly. In cats, fractures were the most common TMJ disorder, followed by osteoarthritis. Clinical signs were observed in all dogs and cats with TMJ fractures, dysplasia, ankylosis, luxation, and tumors; however, only 4 of 15 dogs and 2 of 4 cats with osteoarthritis alone had clinical signs. Results indicated that TMJ disorders were frequently present in combination. Osteoarthritis was the most common TMJ disorder in dogs and the second most common TMJ disorder in cats. Computed tomography should be considered as a tool for the diagnosis of TMJ disorders in dogs and cats with suspected orofacial disorders and signs of pain. (J Am Vet Med Assoc 2013;242:69-75).

    Objective To describe CT findings in dogs and cats with temporomandibular joint (TMJ) disorders. Design Retrospective case-series. Animals 41 dogs and 17 cats. Procedures Medical records and CT images of the skull were reviewed for dogs and cats that were examined at a dentistry and oral surgery specialty practice between 2006 and 2011. Results Of 142 dogs and 42 cats evaluated, 41 dogs and 17 cats had CT findings consistent with a TMJ disorder. In dogs, the most common TMJ disorder was osteoarthritis; however, in most cases, there were other TMJ disorders present in addition to osteoarthritis. Osteoarthritis was more frequently identified at the medial aspect rather than the lateral aspect of the TMJ, whereas the frequency of osteoarthritic involvement of the dorsal and ventral compartments did not differ significantly. In cats, fractures were the most common TMJ disorder, followed by osteoarthritis. Clinical signs were observed in all dogs and cats with TMJ fractures, dysplasia, ankylosis, luxation, and tumors; however, only 4 of 15 dogs and 2 of 4 cats with osteoarthritis alone had clinical signs. Conclusions and Clinical Relevance Results indicated that TMJ disorders are frequently present in combination. Osteoarthritis was the most common TMJ disorder in dogs and the second most common TMJ disorder in cats. Computed tomography should be considered as a tool for the diagnosis of TMJ disorders in dogs and cats with suspected orofacial disorders and pain. PMID:23234284

    Full Text Available Approximately 6 to 16% of patients with trigeminal neuralgia symptoms present intracranial tumors, the most common being the vestibular schwannoma (acoustic neuroma. Some symptoms reported by patients include hearing loss, tinnitus, headaches, vertigo and trigeminal disturbances. An increased muscle response in the surrounding head and neck musculature may also be observed, which mimics signs and symptoms of temporomandibular disorders. In these cases, magnetic resonance imaging (MRI has proved to be a useful tool in tumor diagnosis. The differential diagnosis between myofascial and neuralgic pain is important, as both may present similar characteristics, while being of different origin, and demanding special treatment approaches. The purpose of this paper is to demonstrate the relationship among trigeminal neuralgia symptoms, intracranial tumors and temporomandibular dysfunction by presenting a clinical case.Aproximadamente 6 a 16% dos pacientes com sintomas de neuralgia trigeminal apresentam tumores intracranianos, sendo mais comum o schwannoma vestibular (neurinoma do acústico. Alguns sintomas relatados pelos pacientes são perda da audição, zumbido, dores de cabeça, vertigens e distúrbios trigeminais. Uma resposta muscular aumentada na musculatura associada da cabeça e do pescoço também pode ser observada, o que pode mimetizar sinais e sintomas de desordens temporomandibulares. Nestes casos é de grande valia o uso de imagem de ressonância magnética (IRM para detecção de tumores. É importante, também, a diferenciação de dores miofasciais e neurálgicas, pois ambas podem apresentar características semelhantes, mas com origens e tratamentos diferentes. O objetivo desse trabalho foi demonstrar através de relato de caso clínico a associação entre sintomas de neuralgia trigeminal, tumores intracranianos e disfunção temporomandibular.

    The aim of the present study was to evaluate the effectiveness of global postural reeducation in the treatment of temporomandibular disorder through bilateral surface electromyographic (EMG) analysis of the masseter muscle in a 23-year-old volunteer. EMG values for the masseter were collected at rest (baseline) and during a maximal occlusion. There was a change in EMG activity both at rest and during maximal occlusion following the intervention, evidencing neuromuscular rebalancing between both sides after treatment as well as an increase in EMG activity during maximal occlusion, with direct improvement in the recruitment of motor units during contractile activity and a decrease in muscle tension between sides at rest. The improvement in postural patterns of the cervical spine provided an improvement in aspects of the EMG signal of the masseter muscle in this patient. However, a multidisciplinary study is needed in order to determine the effect of different forms of treatment on this condition and compare benefits between interventions. Therefore, this study can provide a direction regarding the application of this technique in patients with temporomandibular disorder. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The aim of this research was to evaluate, within a controlled clinical study, the effects of a Delaire-type facemask or a modified Jasper Jumper (JJ) used in the treatment of children with Class III malocclusions due to maxillary retrognathia on temporomandibular disorders (TMDs). Forty-six patients with Class III malocclusions referred for orthodontic treatment were divided into two groups, a test and a control. The test group comprised 33 randomly chosen patients (15 females, 18 males) aged 8-11 years. The control group included 13 patients (eight females, five males) with similar features. TMD assessment was performed before and after treatment using a two-axis questionnaire, the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMDs). Qualitative data were evaluated using chi-square and McNemar tests. No statistically significant differences related to the presence of TMD were observed pre- or post-treatment (P > 0.05). The most commonly encountered diagnosis was arthralgia in the JJ group both before and after treatment. Evaluation of joint and muscle regions showed decreased symptoms, apart from the diagnosed discomforts, in the JJ group (P Class III malocclusion treatment did not result in TMD.

    Objective: To correlate the signals and symptoms observed on clinical examination of patients with temporomandibular disorder with the results demonstrated by magnetic resonance imaging. Materials and methods: Thirty patients presenting with signs and symptoms of temporomandibular disorders underwent clinical evaluation and subsequent magnetic resonance imaging. The magnetic resonance imaging studies were independently evaluated by two experienced radiologists. Magnetic resonance imaging studies consisted of 12 images in coronal, T1-weighted sequences with 3 mm-thick slices with the mouth closed, sagittal, T1- and T2-weighted sequences with both open and closed mouth positions, and on progressive opening/closing movement at 5 mm intervals, in order to demonstrate the full mandibular movement. The statistical significance between the clinical findings in the evaluation of the patients and results found on the magnetic resonance imaging studies was analyzed by means the kappa test. Results: Interobserver agreement was respectively 56.7% (kappa = 0.1) and 56.7 (kappa = 0) for the left and right sides. Conclusion: No correlation was found between the clinical and magnetic resonance imaging findings in the diagnoses of disc displacement. (author)

    The purse of this study was to observe the relationship between mandibular asymmetry and Temporomandibular Disorders by means of the cephalometry using the posteroanterior cephalogram and the submentovertex cephalogram which were taken in 35 Temporomandibular Disorder patients and 35 normal persons ranged from 20S to 30S. The results were as follows: 1. The angulation which was formed by the median line with the ANS-Menton line (MAP) was greater in patients group and there was statistically significant difference. 2. The angulation which was formed to the median line with the Menton-Odontoid process tip line (MES), the difference of the distances from the center of the posterior surface of the both condyles to the most anterior point of the chin (DD), the difference of the distances from the center of the both condyles to the horizontal reference line (DE), the difference of the angulations which were formed by the both condyles axes with the horizontal reference line (DCE), the difference of the lengths of the both condyles (CL) and the difference of the widths of the both condyles (DW) were greater in patients group and there were statistically significant differences. 3. There was reversed correlation between MAP and the difference of the distances from the bilateral points of the lateral margin of the both zygomaticofrontal sutures to the points at the lateral inferior margin of the both antegonial protuberances in mandible (DH). 4. There was reversed correlation between MES and DD, DE, DCE. 5. There was correlation between MAP and MES.

    The aim of this study was to investigate the association between symptoms of temporomandibular disorders (TMD), quality of life, and malocclusion. A cross-sectional observational design study was utilized among 248 schoolchildren aged 12 years old. Symptoms of TMD were assessed using the Orofacial Pain and Temporomandibular Disorders Triage Questionnaire, and subjects were further evaluated as oral-health-related quality of life (CPQ11-14), tooth clenching/grinding and malocclusion (Dental Aesthetic Index). Chi-square for independence, Odds Ratio and Mann-Whitney test were used (p = 0.05) statistically. Statistically, association was detected between TMD symptoms with pain and worse quality of life (p quality of life and clenching/grinding (p = 0.0120 and 0.0007). The symptoms of TMD are associated with pain and teeth clenching, causing a negative impact on schoolchildren's quality of life; thus, a study of the TMD impact on quality of life is justified.

    Temporomandibular disorders (TMDs) occurs frequently in children and measuring health-related quality of life (HRQL) can complement efficacy measures, offering a complete picture of the impact of disease and treatment on overall well-being. To compare HRQL, pain threshold (PT) and range of motion (ROM) in child patients with temporomandibular disorder (TMD) pain and an age and gender matched control group. The study design was a controlled cross-sectional study. Forty-two children participated in the study. Twenty-one child patients referred to a dental pediatric clinic for specialist treatment because of TMD pain and an age and gender matched control group completed the Child health questionnaire-child form 87 (CHQ-CF87). PT was measured with Pain matcher and ROM in terms of maximum unassisted mandibular opening was measured with a ruler. The child patients with pain more than once a week had a pain duration ranging from 3 months to almost 6 years. The median for pain intensity measured with visual analogue scale (VAS) was 47 ranging from 5 to 80 and the median for behavioral rating scale (BRS) was 3 ranging from 1 to 4. Child patients with TMD pain more than once a week reported significantly lower scores in CHQ-CF87 when compared with a control group. The results for PT and ROM were non-significant. CHQ-CF87 could be used for measuring health and to evaluate the efficacy of treatment in child patients with TMD pain.

    Introduction. Tension-Type Headache (TTH) is the most prevalent headache often associated with impaired function and quality of life. Temporomandibular Disorders (TMD) and TTH frequently coexist; characterized by pericranial tenderness and impact on daily life. We aim to apply a standardized questionnaire for TMD to characterize and analyse an eventual relation between sleep and oral health in TTH in a controlled design. Material and Methods. 58 consecutive TTH patients and 58 healthy controls were included. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire, Oral Health Impact profile (OHIP) and questionnaires for sleep were applied. Results. TTH-patients had significantly higher pain scores (P quality of life (P < 0.001), and higher total sleep scores (P < 0.001) compared to controls. Conclusion. For the first time we have identified a clear relation between TTH and TMD symptoms, depression, anxiety, poor sleep, and impairments of oral function in carefully classified patients. These findings indicate a close, but incomplete, overlap between TTH and TMD. Their underlying pathophysiological mechanisms need further research. PMID:24349777

    Eagle syndrome (ES) is a rare disorder that can be responsible for orofacial pain. To describe the treatment of an elderly patient affected by ES and temporomandibular disorders (TMD). A patient complained of constant pain of the right temporomandibular joint (TMJ) and of the sensation of having a foreign body in the throat. Based on the patient's medical history and symptoms, a TMJs internal derangement and concomitant ES were suspected. A magnetic resonance and a computerised tomography confirmed the clinical diagnosis. A conservative treatment was initially performed to re-establish a functional occlusion. The rehabilitative treatment alleviated the pain almost totally. A slight residual uncomfortable sensation of the presence of a foreign body in the throat persisted after the oral rehabilitation but without any influence on the quality of life. In elderly patients complaining a chronic orofacial pain, the possibility of a concomitant TMD and ES has to be considered to correctly identify the source of pain. A conservative approach to identify weather TMD is the main source of pain is preferable, avoiding unnecessary invasive treatments. © 2016 John Wiley & Sons A/S and The Gerodontology Association.

    2015-11-01

    The purpose of this review was to present a comprehensive review of the scientific evidence available in the literature regarding the effect of altering the occlusal vertical dimens-ion (OVD) on producing temporomandibular disorders. The authors conducted a PubMed search with the following search terms 'temporoman-dibular disorders', 'occlusal vertical dimension', 'stomatognatic system', 'masticatory muscles' and 'skeletal muscle'. Bibliographies of all retrieved articles were consulted for additional publications. Hand-searched publications from 1938 were included. The literature review revealed a lack of well-designed studies. Traditional beliefs have been based on case reports and anecdotal opinions rather than on well-controlled clinical trials. The available evidence is weak and seems to indicate that the stomatognathic system has the ability to adapt rapidly to moderate changes in occlusal vertical dimension (OVD). Nevertheless, it should be taken into consideration that in some patients mild transient symptoms may occur, but they are most often self-limiting and without major consequence. In conclusion, there is no indication that permanent alteration in the OVD will produce long-lasting TMD symptoms. However, additional studies are needed. © 2015 John Wiley & Sons Ltd.

    To investigate the prevalence of temporomandibular disorders (TMD) in the 46-year-old cohort subjects from the Northern Finland Birth Cohort 1966 (NFBC 1966). Altogether, 1,962 subjects (1,050 women, 912 men) participated in a clinical medical and dental examination and responded to questionnaires in 2012 to 2013. The stomatognathic examination was performed according to a modified protocol of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Pearson's chi-square test and Fisher's exact test were used to analyze the signs of TMD between genders, and logistic regression models were used to analyze the relationship between self-reported pain associated with TMD and modified DC/TMD protocol (P TMJ) (26.2%) and palpation pain in the masticatory muscles (11.2%). Women had signs of TMD more often than men (P TMJ and the most common TMD diagnosis was disc displacement with reduction. The prevalence of TMD signs among the examined cohort subjects was 34.2%. TMD was diagnosed in women more often than in men. The results are comparable with other corresponding population-based studies in adults.

    A growing body of evidence suggests that bruxism exists in two separate manifestations. However, little is known about the association between specific manifestations of bruxism and temporomandibular disorder (TMD) pain. The aim of our study was to analyze the association between TMD pain and specific diagnoses of bruxism (sleep, awake, and mixed diagnosis of sleep and awake bruxism). 508 adult patients (296 women and 212 men), aged between 18 and 64 years (mean age 34±12 years), attending to a clinic for general dental treatment. Patients were asked to fill an anonymous questionnaire, consisting of three questions, verifying the presence of TMD pain and two forms of bruxism. All questions were based on the Polish version of the Research Diagnostic Criteria for Temporomandibular Disorders patient history questionnaire. Cross tabulation was done, and χ 2 was used as a test of significance to find the association between the variables. Awake bruxism was associated with TMD pain only in men (χ 2 =7.746, pbruxism was associated with TMD pain in both women (χ 2 =10.486, pbruxism and TMD pain. Gender-related differences in the presence of all bruxism diagnoses were also statistically insignificant. Interaction between sleep and awake bruxism may increase the risk for TMD pain. We suggest considering concomitance as a confounder, when studying sleep or awake bruxism. Copyright © 2016 Polish Neurological Society. Published by Elsevier Urban & Partner Sp. z o.o.

    This study examined the differences in the masticatory function of patients with temporomandibular disorder (TMD) in Korea. The experimental groups were as follows: 23 patients with painful arthralgia classified as pain group according to the research diagnostic criteria for temporomandibular disorder (RDC/TMC) and 28 patients with pain-free disc displacement and reduction classified as clicking group. The subjects were obtained from those who had visited Yonsei University Dental Hospital from 2007 to 2008. Twenty dental students without TMD symptoms were enroled as the normal control group. The Mixing Ability Index (MAI) was used as the objective index, and the Food Intake Ability (FIA) Index, Visual Analogue Scale (VAS) and oral health impact profile (OHIP) were used as the subjective indices. The MAI, FIA and VAS were significantly lower in the pain group than in the normal and clicking groups (Pmasticatory function in patients with TMD in Korea, and the joint sound, not the masticatory function, affects the declining OHIP. © 2010 Blackwell Publishing Ltd.

    This study aimed (1) to identify the diagnostic subsets of a patient population with temporomandibular disorders (TMD) referred from dental professionals to a physical therapist (PT) in an outpatient physical therapy practice and (2) to use the characteristics of this TMD population to assist clinical decision making in the management of TMD. This was an institutional review board-approved, retrospective study of 511 patients referred to a PT. The PT followed the diagnostic guidelines of axis I of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). All 8 diagnostic subsets of the RDC/TMD were diagnosed among the 511 patients. Concurrent diagnostic subsets, cervical spine involvement, and oral appliance use were described. PTs in an outpatient practice should be proficient in the use of the RDC/TMD. Characteristics identified with this patient population suggest that dentists should involve the services of PTs early in the management of patients with TMD and cervical symptoms.

    2017-08-14

    To document the clinical phenotype of temporomandibular disorder (TMD) patients with concomitant upper airway resistance syndrome (UARS) in a South East Asian population. A multi-center prospective series of 86 TMD patients (26 men and 60 women / mean age 35.7 years) with UARS. All had excessive daytime sleepiness, high arousal index and apnea-hypopnea index (AHI)temporomandibular joint (TMJ) arthralgia while 90.7% reported sleep bruxism (SB). Unlike patients with obstructive sleep apnea (OSA), hypertension was uncommon (4.7%) whilst depression was prevalent at 68.6% with short REM latency of 25% documented in 79.6% and 57.6% of these depressed patients, respectively. 65.1% displayed a posteriorly displaced condyle at maximum intercuspation with or without TMJ clicking. Most exhibited a forward head posture (FHP) characterized by loss of normal cervical lordosis (80.2%), C0-C1 narrowing (38.4%) or an elevated hyoid position (50%), and 91.9% had nasal congestion. The TMD-UARS phenotype may have originally developed as an adaptive response to 'awake' disordered breathing during growth. Patients with persistent TMD and/or reporting SB should be screened for UARS and chronic nasal obstruction, especially when they also present with FHP. The lateral cephalogram is a useful tool in the differentiation of UARS from other OSA phenotypes. This article is protected by copyright. All rights reserved. This article is protected by copyright.

    To systematically compare clinical findings and psychosocial factors between patients suffering from atypical odontalgia (AO) and an age- and gender-matched group of patients with temporomandibular disorders (TMD). Forty-six AO patients (7 men and 39 women; mean age, 56 years) were compared with 41 TMD patients (8 men and 33 women; mean age, 58 years). Mean pain intensity at the time of inclusion in the study was similar between the groups (TMD: 5.3 +/- 0.4, AO: 5.0 +/- 0.3), but pain duration was longer in AO patients (AO: 7.7 +/- 1.1 years, TMD: 4.5 +/- 0.1 years). Eighty-three percent of the AO patients and 15% of TMD patients reported pain onset in relation to dental/surgical procedures. Episodic tension-type headache (TTH) occurred equally in both groups (TMD: 46%, AO: 46%), but TMD patients more frequently experienced chronic TTH (TMD: 35%, AO: 18%), myofascial TMD (TMD: 93%, AO: 50%), and temporomandibular joint disorders (TMD: 66%, AO: 2%). Overall, TMD patients had lower pressure pain thresholds and poorer jaw function than AO patients. Mean depression and somatization scores were moderate to severe in both groups, and widespread pain was most common in TMD patients. AO and TMD share some characteristics but differ significantly in report of dental trauma, jaw function, pain duration, and pain site.

    This study evaluated the relationship between anxiety levels and severity degrees of chronic orofacial pain of temporomandibular disorder in brazilian university students. 150 volunteers (117 men and 33 women), with age ranging from 17 to 30 years, were subjects to this study. Spielberger's trait-state anxiety inventory was used to evaluate trait and state anxiety of the students, while examination for chronic orofacial pain was performed in accordance with the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Association between anxiety levels and severity degrees of chronic orofacial pain was tested using the Chi-square test. The significance level was set at porofacial pain was classified as degree 1 in 85.7% (n=42) and as degree 2 in 14.3% (n=7) of them. Based on the results of the Spielberger's trait-state anxiety inventory, the majority of the students had moderate anxiety (48.6% and 48.1%, respectively). The correlation between trait-anxiety levels and chronic orofacial pain degrees was significant and positive (porofacial pain degrees (p>.05). It was concluded that chronic orofacial pain of TMD could be present in university students and anxiety may be related. Copyright © 2010 Japan Prosthodontic Society. Published by Elsevier Ltd.

    The high prevalence of temporomandibular disorders and tinnitus along with the negative effects on the quality of life of affected individuals makes this association a matter of public health. To assess the knowledge of primary health care professionals about the interrelationship between temporomandibular disorders and tinnitus. This was a quantitative cross-sectional study, using a structured, self-administered questionnaire for a group of 54 dental surgeons. The statistical analysis used involved descriptive analyses through absolute and relative frequency distributions. The results showed that the professionals do not, as a routine, examine the temporomandibular joints and masticatory muscles during physical examination. In addition, there was a low percentage of correct answers on questions that assess knowledge. There is a need to inform dentists about the interrelationship between temporomandibular disorders and tinnitus. Furthermore, there is a need to encourage managers to establish teaching and learning tools that support and strengthen the role of dentists in primary health care. In this way, routine visits might minimize these disorders, and thus contribute to the quality of life of the population.

    Facial trauma in sports has been associated with temporomandibular disorders. Because of the intensity and duration of training needed for elite-level competitions, high-performance athletes can have two to five times more traumatic injuries than recreational athletes. This study aimed to investigate the prevalence of temporomandibular disorders in high-performance martial arts fighters and compare it with the prevalence in recreational athletes and non-athletes. The Research Diagnostic Criteria for Temporomandibular Disorders was used to diagnose and classify professional karate-do practitioners (group I; n = 24), amateur karate-do practitioners (group II; n = 17), high-performance mixed martial arts fighters (group III; n = 13), and non-athletes (n = 28). The groups were compared with the chi-square test and tested for the difference between two proportions using a significance level of 5% (P 0.05). A diagnosis of arthralgia from disk displacement was made more frequently in groups I (45.8%; P = 0.013) and III (38.5%; P = 0.012) than in group IV (7.1%). The chronic pain associated with TMD was low intensity and low disability. While there was a high prevalence of temporomandibular disorders in the professional athletes in our study, the prevalence of the condition in recreational athletes was similar to that in individuals who did not practice martial arts. © 2015 John Wiley & Sons A/S.

    Aqua Titan (AT), comprising microscopic titanium particles dispersed in water, has been reported to have beneficial effects on muscle tissue. This study investigated the effects of local application of AT on symptoms in patients with muscle disorders of the temporomandibular joint (TMJ) compared to patients with joint disorders of the TMJ. Sixteen patients with unilateral masseter muscle pain during motion (muscle disorder group) and six patients with unilateral TMJ pain during motion (joint disorder group) applied an AT-permeated patch over the painful area every night for 2 weeks. Symptoms were evaluated clinically at the initial visit and 1 and 2 weeks later. Clinical symptoms in the joint disorder group showed no tendency towards improvement after 2 weeks. In contrast, mouth opening range with/without pain, visual analogue scale (VAS) scores for pain during mouth opening and eating, and activities of daily living (ADL) scores in the muscle disorder group were improved significantly after 2 weeks. Multiple comparison tests in the muscle disorder group showed significant improvements in the VAS for eating and ADL score after 1 week. These results suggest that the AT patch has a potential supplementary role in the treatment of patients with muscle disorders of the TMJ.

    The present study was comprised of 43 patients (16 men) with cervicogenic headaches for over three months, diagnosed according to the International Classification of Diagnostic Criteria of Headaches (ICDH-II). The patients were randomly assigned to receive either manual therapy for the cervical region (usual care group) or additional manual therapy techniques to the temporomandibular region to additionally influence temporomandibular disorders (TMD). All patients were assessed prior to treatment, after six sessions of treatment, and at a six-month follow-up. The outcome criteria were: intensity of headaches measured on a colored analog scale, the Neck Disability Index (Dutch version), the Conti Anamnestic Questionnaire, noise registration at the mandibular joint using a stethoscope, the Graded Chronic Pain Status (Dutch version), mandibular deviation, range of mouth opening, and pressure/pain threshold of the masticatory muscles. The results indicate in the studied sample of cervicogenic headache patients, 44.1% had TMD. The group that received additional temporomandibular manual therapy techniques showed significantly decreased headache intensities and increased neck function after the treatment period. These improvements persisted during the treatment-free period (follow-up) and were not observed in the usual care group. This trend was also reflected on the questionnaires and the clinical temporomandibular signs. Based on these observations, we strongly believe that treatment of the temporomandibular region has beneficial effects for patients with cervicogenic headaches, even in the long-term.

    This review aims at presenting a current view on the most frequent factors involved in the mechanisms causing temporomandibular disorders (TMD). We conducted a critical review of the literature for the period January 2000 to December 2014 to identify factors related to TMD development and persistence. The etiology of TMD is multidimensional: biomechanical, neuromuscular, bio-psychosocial and biological factors may contribute to the disorder. Occlusal overloading and parafunctions (bruxism) are frequently involved as biomechanical factors; increased levels of estrogen hormones are considered biological factors affecting the temporo-mandibular-joint. Among bio-psychosocial factors, stress, anxiety or depression, were frequently encountered. The etiopathogenesis of this condition is poorly understood, therefore TMDs are difficult to diagnose and manage. Early and correct identification of the possible etiologic factors will enable the appropriate treatment scheme application in order to reduce or eliminate TMDs debilitating signs and symptoms.

    Pain related to temporomandibular disorders (TMD) is a common problem in modern societies. The aim of the article is to present the concepts of TMD pain clinical management. A survey was performed using the PubMed, SCOPUS and CINAHL databases for documents published between 1994 and 2014. The following search keywords were selected using MeSH terms of the National Library of Medicine in combination: TMD pain, TMD, TMJ, TMJ disorders, occlusal splint, TMD physiotherapy, TMJ rheumatoid disorders and TMJ surgery. Original articles and review papers which presented the clinical relevance and practical validity regarding the possibility of application in TMD management have been included. Authors have excluded articles without outstanding practical aspect and evidence-based background. A first selection was carried out by reviewing titles and abstracts of all articles found according to the criteria. After that the full texts of potentially suitable articles were assessed. In line with these criteria, among 11467 results the writers have included 66 papers. The most commonly reported conservative treatments are massage therapy and individually fabricated occlusal splints. In addition to massage, other popular methods include manual therapy and taping, warming/cooling of aching joints, and light and laser therapy. Drugs are also commonly used. In the most severe cases of the temporomandibular joint degeneration, surgical restoration of the joint is sometimes applied. The authors concluded that conservative treatment including counselling, exercises, occlusal splint therapy, massage, manual therapy and others should be considered as a first choice therapy for TMD pain because of their low risk of side effects. In the case of severe acute pain or chronic pain resulting from serious disorders, inflammation and/or degeneration pharmacotherapy, minimally invasive and invasive procedures should be considered.

  4. The usefulness of diagnostic imaging for the assessment of pain symptoms in temporomandibular disorders

    Full Text Available The causes of pain symptoms in the temporomandibular joint (TMJ and masticatory muscle (MM regions may not be determined by clinical examination alone. In this review, we document that pain symptoms of the TMJ and MM regions in patients with temporomandibular disorders (TMDs are associated with computed tomography and magnetic resonance (MR findings of internal derangement, joint effusion, osteoarthritis, and bone marrow edema. However, it is emphasized that these imaging findings must not be regarded as the unique and dominant factors in defining TMJ pain. High signal intensity and prominent enhancement of the posterior disk attachment on fat saturation T2-weighted imaging and dynamic MR imaging with contrast material are closely correlated with the severity of TMJ pain. Magnetic transfer contrast, MR spectroscopy, diffusion tensor imaging, and ultrasonography findings have helped identify intramuscular edema and contracture as one of the causes of MM pain and fatigue. Recently, changes in brain as detected by functional MR neuroimaging have been associated with changes in the TMJ and MM regions. The thalamus, the primary somatosensory cortex, the insula, and the anterior and mid-cinglate cortices are most frequently associated with TMD pain.

    Temporomandibular disorders (TMDs) represent a broad spectrum of conditions associated with the temporomandibular joints and the neuromuscular system. Evidence-based diagnostic criteria for various TMDs are emerging, while corresponding treatment procedures remain less clear. As a result, the clinician may be uncertain how to best care for TMD patients. The objectives of this evidence-based review were to outline the various types of occlusal devices, assess the efficacy of occlusal splints in treating TMD patients, and create a treatment rubric based on diagnostic criteria and condition severity. A select literature review as to the effectiveness and efficacy of occlusal device TMD therapy revealed that stabilization splint intervention and control treatments had a positive effect in reducing TMD-related symptoms; minimal statistically significant differences were noted between intervention and control treatments. Stabilization splints are effective as a reversible treatment for patients with TMD. Other therapies and occlusal devices may be beneficial when used for a specific TMD diagnostic protocol. A treatment rubric based on diagnostic criteria and condition severity may assist the clinician.

    Data regarding the effectiveness of Kinesio Taping in temporomandibular disorders (TMD) is scarce. To determine the efficacy of Kinesio Taping (KT) in patients with TMD. Patients with TMDs were randomized into experimental and control groups. The experimental group (n= 14) received KT in combination with counseling and jaw exercise, whilst controls (n= 14) were given the regimen of counseling and exercise alone. Jaw movements, Visual analogue scale (VAS) scores and self-reported measures (functional limitation and masticatory efficiency) were evaluated at baseline, first and sixth weeks of the treatment. Biobehavioral questionnaire was filled out at baseline and at sixth week. Active mouth opening improved more in the experimental group than controls (p= 0.003). In the experimental group, VAS for temporomandibular joint, masticatory efficiency and functional limitation improved significantly at the sixth week when compared to baseline (p= 0.011, p= 0.001 and p= 0.001, respectively), but not in controls. Subjective treatment efficacy was higher in the experimental group than that of controls (p= 0.000). Pain, depression and disability scores reduced significantly in the experimental group (p= 0.001, p= 0.006 and p= 0.01, respectively), but not in controls. In conclusion, KT in combination with counseling and exercise is more effective than counseling and exercise alone in TMDs.

    The purpose of this study was to examine the relationship between anterior disc displacement and disc deformity in patients with temporomandibular disorder (TMD). We studied 50 temporomandibular joints (TMJs) in 50 patients with TMD. MR images were taken by the spin echo method using spin echo (T{sub 1}-weight: sagittal and coronal) and fast spin echo (T{sub 2}-weight: sagittal) sequences. These MR images were evaluated by two dental radiologists. The results obtained were as follows: The cases of anterior disc displacement were classified as slight in 13 (26%), moderate in 18 (36%) and severe in 6 (12%). With regard to disc configuration, 22 were biconcave (44%) which thought to be normal, 6 were E-type (12%), 6 were biplanar (12%) and 16 were biconvex (32%) in terms of deformity. Among 37 anterior disc displacement cases, 10 were moderate (56%) and 4 were severe (67%) cases showing a biconvex type of disc. There results suggest that anterior disc displacement is related to disc deformity, especially in cases of severe anterior displacement. (author)

    Temporomandibular disorders (TMD) are a class of degenerative musculoskeletal conditions associated with morphologic and functional deformities that affect up to 25% of the population, but their etiology and progression are poorly understood and, as a result, treatment options are limited. In up to 70% of cases, TMD are accompanied by malpositioning of the temporomandibular joint (TMJ) disc, termed "internal derangement." Although the onset is not well characterized, correlations between internal derangement and osteoarthritic change have been identified. Because of the complex and unique nature of each TMD case, diagnosis requires patient-specific analysis accompanied by various diagnostic modalities. Likewise, treatment requires customized plans to address the specific characteristics of each patient's disease. In the mechanically demanding and biochemically active environment of the TMJ, therapeutic approaches that can restore joint functionality while responding to changes in the joint have become a necessity. One such approach, tissue engineering, which may be capable of integration and adaptation in the TMJ, carries significant potential for the development of repair and replacement tissues. The following review presents a synopsis of etiology, current treatment methods, and the future of tissue engineering for repairing and/or replacing diseased joint components, specifically the mandibular condyle and TMJ disc. An analysis of native tissue characterization to assist clinicians in identifying tissue engineering objectives and validation metrics for restoring healthy and functional structures of the TMJ is followed by a discussion of current trends in tissue engineering.

    To analyze the relationship between symptoms and signs of temporomandibular disorders (TMD) and the patients' quality of life (QOL). A total of 492 TMD patients were included in this study. The clinical examination results were recorded using Fricton index of temporomandibular joint function. "Visual analog scale (VAS) evaluation of QOL disturbance" was designed to quantitate patients' QOL, to evaluate the degree that the patients QOL was affected. Chewing, daily life and emotion among all 8 items of QOL were frequently affected by TMD, and joint clicking had the least influence on QOL. Intermittent closed lock had more severe interference with QOL than joint clicking only. Severe and moderate pain or limited mouth opening affected the QOL more severely than mild pain or mild limited mouth opening. The simple linear relationship between Fricton index and patients' QOL was poor (r < 0.4). Pain is the most frequently seen symptom in TMD. TMD could affect patients' QOL, including both physical and social-psychological functions. The results suggest that the patients' QOL as well as TMD symptoms and signs should be considered in the management of TMD.

    The pathophysiology and underlying pain mechanisms of temporomandibular disorders (TMD) are poorly understood. The aims were to assess somatosensory function at the temporomandibular joints (TMJs) and to examine whether conditioned pain modulation (CPM) differs between TMD pain patients (n = 34) and healthy controls (n = 34). Quantitative sensory testing was used to assess the somatosensory function. Z-scores were calculated for patients based on reference data. Conditioned pain modulation was tested by comparing pressure pain thresholds (PPTs) before, during, and after the application of painful and nonpainful cold stimuli. Pressure pain thresholds were measured at the most painful TMJ and thenar muscle (control). Data were analyzed with analyses of variance. Most (85.3%) of the patients exhibited at least 1 or more somatosensory abnormalities at the most painful TMJ with somatosensory gain with regard to PPT and punctate mechanical pain stimuli, and somatosensory loss with regard to mechanical detection and vibration detection stimuli as the most frequent abnormalities. There was a significant CPM effect (increased PPT) at both test sites during painful cold application in healthy controls and patients (P painful cold application between groups (P = 0.227). In conclusion, somatosensory abnormalities were commonly detected in TMD pain patients and CPM effects were similar in TMD pain patients and healthy controls.

    Full Text Available Complicated tooth extractions may lead to various post-extraction complications, including Temporomandibular Joint Disorders (TMD. Despite of the rare incidence, a delayed treatment of the TMD will cause more problems in the future as well as increased morbidity rate. The purpose of the current study was to elaborate the symptoms as well as the management of TMD as a post tooth extraction complication. The types of TMD as a post tooth extraction complication includes dislocated condyle, osteoarthritis, fracture condyle and disc displacement. These type of complications may resulted from an extensive opening of the mouth as well as an over pressure on the mandible during tooth extraction. In relation to this, some of the TMD symptoms that might cause a certain level of interference for patients may include pain, limited mouth opening and joint sounds, with pain and limited mouth opening as the initial symptoms. The first measure of the pain management would be warm light compress around the TMJ followed by a soft diet for food intake. A definitive treatment should then be based on the diagnosis of the TMD. It is concluded that TMD may occur as a complication of a tooth extraction that initiated by pain and limited mouth opening. Immediate treatment would be pain relieve and load reduction of the Temporomandibular Joint by employing soft diet and mandibular movement restriction.

    To propose a visual method to screen and assess psychosocial functioning in temporomandibular disorder (TMD) pain patients in comparison with age- and gender-matched healthy controls by forming individual profiles and to evaluate the association between psychosocial profiles and quantitative sensory testing (QST) findings of TMD pain patients. TMD patients (n = 58) and control participants (n = 41) completed a set of questionnaires profiling their psychosocial function, and QST was performed at the temporomandibular joint (TMJ) on both sides of the face in all participants. Psychosocial parameters from the Research Diagnostic Criteria for TMD (RDC/TMD), Oral Health Impact Profile (OHIP), and Pain Catastrophizing Scale (PCS) instruments were transformed into T scores, and QST parameters were transformed into z scores based on reference data. Group differences for psychosocial T scores were analyzed with t tests. T scores of psychosocial parameters and z scores of QST parameters were correlated using Spearman's correlation (ρ). Most (96.6%) TMD pain patients exhibited one or more parameters indicative of psychosocial distress, with psychological disability scores being the scores most frequently encountered outside the reference 95% confidence intervals (CI). TMD patients were psychosocially more distressed with regard to all psychosocial parameters compared with controls (P psychosocial profiles created an easy overview of psychosocial function in TMD pain patients. Increased sensitivity to tactile stimuli was associated with higher sleep dysfunction T scores.

    Studies concerning the role of denture status on in temporomandibular disorders (TMD) are scarce. The aim of this study was to evaluate the association of tooth loss and denture status with clinical findings of TMD. The data were obtained from 6316 subjects aged ≥ 30 years from the Finnish Health 2000 Survey. The associations between clinically assessed TMD findings and number of teeth, wearing of removable dentures, need for denture repair and age of the dentures were analysed by means of chi-square test and logistic regression. Among women after adjusting for age, having fewer teeth or wearing complete dentures associated with restricted maximum interincisal distance and pain on palpation of the temporomandibular joints (TMJ) and masticatory muscles. After adding education level and depression in the model, the associations between TMJ pain and explanatory variables were weakened. Among men, having a higher number of teeth associated with occurence of TMJ crepitation. Subjective need for repair of dentures and having a denture aged ≥ 5 years associated with pain on palpation in masticatory muscles among women. Among men, both the objective and subjective need for denture repair and having at least one denture aged ≥ 5 years or been repaired during the past 5 years associated negatively with the presence of TMJ crepitation. It can be concluded that edentulousness, wearing of complete dentures and poor condition of dentures associate with pain-related TMD findings among women. Psychosocial factors have a modifying effect on these associations. © 2012 Blackwell Publishing Ltd.

    The aim of this review was to investigate the effectiveness of counselling and other self-management-based therapies on muscle and temporomandibular joint (TMJ) pain relief and increasing the functional abilities of patients with temporomandibular disorders (TMD). A systematic literature review was conducted by three independent reviewers and included articles published up to 2012. PubMed and Cochrane Library electronic databases were used in addition to hand-searching to assess clinical outcomes for counselling and self-management approaches for TMD treatment. The review yielded 581 records that were narrowed down to 7. All included studies were classified as blind-randomized controlled clinical trials. The selected articles analysed revealed that counselling was able to improve tenderness upon masticatory muscle palpation and maximum mouth opening with and without pain in patients with TMD, with similar results to those of interocclusal appliances approaches. Thus, counselling- and self-management-based therapies could be considered a conservative low-cost and beneficial treatment alternative for treating TMD to potentially improve psychological domains and remove harmful behaviours for the control of the signs and symptoms of TMD. © 2013 John Wiley & Sons Ltd.

    This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. The study subjects included 232 TMD patients. The inclusion criteria in this study were the presence of spontaneous pain or provoked pain on one or both temporomandibular joints (TMJs). The provoked pain was divided into three groups: pain on palpation (G1), pain on mouth opening (G2), and pain on mastication (G3). MRI examinations were performed using a 1.5-T MRI scanner. T1- and T2-weighted images with para-sagittal and para-coronal images were obtained. According to the T2-weighted image findings, the cases of effusions were divided into four groups: normal, mild (E1), moderate (E2), and marked effusion (E3). A statistical analysis was carried out using the χ(2) test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (ppalpation of the masticatory muscles and TMJ (G1) was not related to joint effusion in TMD patients (p>0.05). Spontaneous pain was related to the MRI findings of joint effusion; however, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ was not related to the MRI findings of joint effusion. These results suggest that joint effusion has a significant influence on the prediction of TMJ pain.

    The authors conducted a study in subjects who tested free of psychological stress to determine the position of the condyle and whether that position was related to signs and symptoms of temporomandibular disorders (TMDs). Forty subjects underwent psychological evaluation to ensure freedom from psychological stress. The authors evaluated tenderness of the masticatory muscles and temporomandibular joints (TMJs) by means of bimanual digital palpation, and they determined the positions of the condyle and disk by using magnetic resonance imaging. A total of 23.75 percent of the condyles were displaced away from the centric position either anteriorly (3.75 percent) or posteriorly (20.00 percent). chi(2) analysis showed a relationship between the position of the condyle and displacement of the disk, as well as a relationship between the position of the condyle and tenderness of the TMJs. Although these relationships proved significant, it cannot be assumed that displacement of the condyle away from the centric position is predictive of TMD. Only two subjects were judged to have had TMJ internal derangement. Thus, the absence of psychological stress seems to have played a role in this finding.

    At the present time, there are no reports in the literature on the treatment of temporomandibular joint disorder (TMD) by intrusion of molars using mini-screws. This case report describes the treatment for a female patient, aged 19 years seven months, with a TMD and an excessive lower anterior facial height. Overjet and overbite were +5.0 mm and +0.5 mm, respectively. The patient had a history of orthodontic treatment in which her first premolars were all extracted. During the first orthodontic treatment, a clockwise mandibular rotation was observed as a result of the increase of posterior dentoalveolar height. She had temporomandibular joint (TMJ) pain during mouth opening and complained of difficulty in eating due to masticatory dysfunction. The pretreatment Schuller views of both TMJ showed a posterior condyle position. In order to correct the overjet, molar relationship and the mandibular condyle position, a miniscrew was inserted into the palatal region of the upper first molar to intrude the upper posterior teeth. As the upper molars were intruded, the overjet was decreased, and a class I molar relationship was achieved by a counterclockwise mandibular rotation. After one year of treatment, an acceptable occlusion was achieved, and the condyle moved into centric position in the glenoid fossa. The patient's teeth continued to be stable, and she had no pain in TMJ after a retention period of three years. The result of this treatment showed that molar intrusion using miniscrew anchorage is effective for treatment of a TMD patient with a posterior condyle position.

Particularly, patients with schizophrenia are quite likely to have signs and symptoms of TMD due to the impairment of their oral health, the use of antipsychotic drugs, and other general health problems. In nonschizophrenic populations, TMD have been considered as the main cause of nondental pain in the orofacial region, involving mechanisms associated with changes in masticatory activity at the cortical and neuromuscular levels. Individuals with schizophrenia do not usually complain of pain, and TMD is misdiagnosed in this population. In this paper, we aimed to review the clinical aspects of TMD in people with schizophrenia on antipsychotic drug therapy. Keywords: schizophrenia, temporomandibular joint, pain, antipsychotic agents

    Full Text Available The aim of this triple-blind full-randomized clinical trial was to quantify analgesia in masticatory muscles and temporomandibular joints after occlusal splint therapy associated with the adjuvant administration of nonsteroidal anti-inflammatory drugs (NSAID isolated or associated with other therapeutic agents. Pain relief was also recorded. Eighteen volunteers who had been suffering from chronic pain in masticatory muscles due to temporomandibular disorders were selected after anamnesis and assessment using RDC/TMD translated to Portuguese. The 3 proposed treatments were NSAID (sodium diclofenac, panacea (sodium diclofenac + carisoprodol + acetaminophen + caffeine, and a placebo. The total treatment duration was 10 days, preceded and succeeded by patients’ pain assessment. A washout interval of 11 days was established between each therapy. All participants received all treatments in different moments, in a full randomized crossover methodology. The assessment of drug therapies was performed using visual analogue scale for pain on palpation followed by 11-point numerical scale to quantify pain during treatment. Statistical analysis has shown that, after 10 days of treatment, all therapies were effective for pain relief. NSAID therapy promoted analgesia on the third day, while placebo only promoted analgesia in the eighth day. It has been concluded that sodium diclofenac used as splint adjuvant therapy, promotes significant analgesia in a shorter time.

    Mandibular movement values are an important parameter within the clinical evaluation of the temporomandibular joint. Limited or increased movement is a sign of dysfunction. Normal values used as reference correspond to adult populations, and information on child populations is scant. The aim of this study was to establish reference measurements of children with primary (Group A) and mixed dentition (Group B) without signs of temporomandibular disorders. The study population comprised 212 boys and girls, aged 3 to 11 years, attending a state school in the San Martin district in the province of Buenos Aires, who presented no joint sounds, clicking or pain. A calibrated operator determined maximal opening, protrusion, and lateral movements. Group A (n=105): mean age 4.61+/-0.9; maximal opening 38.59 mm +/- 4.03; protrusion 3.71 mm+/-1.79; right lateral movement 5.43 mm+/-1.83 and left lateral movement 5.52 mm +/- 1.73. Group B (n= 107): mean age 6.9+/-1.65; maximal opening 41.97 mm +/- 5.27; protrusion 3.96 mm+/-1.92; right lateral movement 6.05 mm+/-1.99 and left lateral movement 6.13 mm+/-2.21. Opening and lateral movements were found to increase with age. Comparison between groups using Welch t Test showed significant differences in maximal opening (pmovement. Mandibular movements are associated with growth. Mandibular movements of pediatric patients must be assessed in relation to age and type of dentition.

    Alexandre Fiorelli

    Full Text Available Abstract Changes in the suboccipital muscles and the hamstrings may interfere with head posture and the biomechanics of the temporomandibular joint, both of which contribute to the severity of temporomandibular disorders (TMD. The objective of this investigation was to evaluate the effects of a global postural exercise program (GPEP on pain intensity and mouth-opening range of motion (ROM in women with TMD. The participants were comprised of 30 women with TMD who were divided into two groups: an experimental group (EG and a control group (CG. A pressure algometer was used for pain assessment and a paquimeter was used to measure ROM. The duration of the GPEP was six weeks. In the EG, there was a reduction in pain intensity and an increase in mouth-opening ROM compared to the CG. Therefore, we concluded that the GPEP was effective in relieving pain in all of the evaluated muscles and regions, and in increasing mouth-opening ROM in women with TMD.

    Full Text Available Introduction: The aim of this study was to investigate whether there is any relationship between the condition of complete dentures and TMDs. Methods: The sample consisted of 61 consecutive patients (35 females and 26 males who were admitted to the Department of Prosthodontics of Mashhad Faculty of Dentistry for fabrication of new complete dentures.  The age range of the participants was between 32 and 80 years, with the mean age of 57.05±10.26 years. The patients were examined by two prosthodontists. Using a questionnaire, the first prosthodontist asked the patients about their habits and history of trauma to the temporomandibular joints (TMJs. She then examined the participants for signs and symptoms of temporomandibular disorders (TMDs.  The second prosthodontist examined each participant's existing denture and checked its fit, stability, retention, occlusion, and centric relation, and recorded how long it had been in service. The examination was double blind. The data were recorded in examination sheets. Results: The relationship between TMDs and denture fit, stability, retention, centric relation and occlusion was analyzed using Fisher’s Exact Test. No significant relationship was found between denture characteristics and TMDs in complete denture wearers (P-value>0.05. Conclusion: Complete denture characteristics did not play a role in the development of TMDs in edentulous patients.

    The pain from temporomandibular disorder (TMD) is often associated with physical symptoms of other chronic pain disorders and comorbidities, such as generalised muscle and joint pain. However, this association is not widely studied. To evaluate the prevalence of comorbid pain in joints, specifically in the knees, hips, ankles, shoulders, wrists and elbows, in individuals with and without TMD. We evaluated 337 patients from a public hospital in the city of Rio de Janeiro, Brazil. The Research Diagnostic Criteria for TMD questionnaire were used for the diagnosis of TMD. To assess the presence of other joint pain, the patients were asked to answer questions considering: the presence of pain in the knee, hip, ankle, shoulder, wrist and elbow joints and time duration of pain. Individuals with TMD are 5·5 times more likely to present with other joint pain compared with those without the disorder. TMD muscle disorders were most associated with a higher number of pain at the other locations. There was a significant association between the presence of pain at the other locations, muscle (P joint disorders (P = pain at the other locations. Individuals with TMD showed a high prevalence of pain in other joints of the body when compared with individuals without the disorder, and knee pain was the most prevalent pain complaint. © 2016 John Wiley & Sons Ltd.

    The primary objective of this study was to assess the prevalence of temporomandibular disorders (TMDs) and comorbid factors (sleep bruxism and headaches). This study was a cross-sectional population survey in the city of Maringá, state of Paraná, Brazil. Axes I and II of the Research Diagnostic Criteria for TMD (RDC/TMD) were used for assessment of TMD signs and symptoms. The population was users of the Brazilian public health system (SUS), of both sexes, between the ages of 20 and 65 years, and not seeking treatment for TMD. The selected population (N = 1,643) was composed mostly of (a) women (65.9%), (b) married or single individuals (90.6%), (c) Caucasians (70.1%), (d) individuals aged 32.7 ± 10.3 years, (e) individuals earning a medium income (75.1%), and (f) those who had completed a high school education or higher (79.9%). According to the chronic pain grade classification (CPG) in the RDC/TMD Axis II, 36.2% of the population had some degree of TMD pain (CPG I to IV); however, only 5.1% had severe limitation due to pain (CPG III or IV). In the RDC/TMD Axis I diagnoses, 29.5% presented with muscle disorders (group I), 7.9% with disk displacements (group II), and 39.1% with other joint disorders (group III). Headaches were present in 67.9% and awake and sleep bruxism in 30% and 33.4% of the population, respectively. The prevalence of signs and symptoms of TMD was high in this population, but with low disability; however, the proportion of patients in need of treatment was much lower.

    Scleroderma is a disorder involving oral and facial tissues, with skin hardening, thin lips, deep wrinkles, xerostomia, tongue rigidity, and microstomia. The aim of this study was to investigate the prevalence of oral manifestations and temporomandibular disorders (TMD) in Systemic Sclerosis (SSc) patients compared with healthy people. Eighty patients (6 men, 74 women) fulfilling ACR/EULAR SSc Criteria were enrolled. A randomly selected group of 80 patients, matched by sex and age served as control group. The examination for TMD signs and symptoms was based on the standardized Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) through a questionnaire and clinical examination. SSc patients complained more frequently (78.8%) of oral symptoms (Xerostomia, dysgeusia, dysphagia and stomatodynia) than controls (28.7%) (χ² = 40.23 p = 0.001). TMD symptoms (muscle pain on chewing, difficulty in mouth opening, headaches) were complained by 92.5% of SSc patients and by 76.2% of controls (χ² = 8.012 p = 0.005). At the clinical examination, 85% of SSc patients showed restricted opening versus 20.0% of controls (χ² = 67.77 p = 0.001), 81.2% of SSc showed reduced right lateral excursion versus 50% of controls (χ² = 17.316 p = 0.001); 73.8% of SSc showed limited left lateral excursion versus 53.8% of controls (χ² = 6.924 p = 0.009); and 73.8% of SSc had narrow protrusion versus 56.2% of controls (χ² = 5.385 p = 0.02).

    To measure the oral health-related quality of life (OHRQoL) in patients with temporomandibular disorders (TMD) compared to controls and analyze its association with various demographic and clinical parameters. The survey included 187 TMD patients and 200 controls. OHRQoL was measured using the validated Hebrew version of the Oral Health Impact Profile-14 (OHIP-14). A self-report questionnaire assessed personal details, smoking habits, history of trauma and orthodontic treatment, comorbid headaches, oral habits, and pain. TMD patients were divided into diagnostic categories according to the newly recommended diagnostic criteria for TMD (DC/TMD) Axis I protocol. Differences between groups were examined with a Pearson chi-square test for categorical variables and analysis of variance (ANOVA) for continuous variables. Among TMD patients, the diagnostic categories included: (1) masticatory muscle disorders (MMD; n = 38; 20.32%), (2) isolated disorders of the temporomandibular joint (TMJ; n = 46; 24.59%), (3) patients with both MMD and TMJ (TMP; n = 103; 55.08%). Compared to controls, TMD patients exhibited worse global OHIP-14 scores (12.50 ± 8.14 vs 9.58 ± 10.00; P = .002) and worse scores in the following domains: physical pain (P < .001), psychological discomfort (P = .005), physical disability (P = .004), and psychological disability (P = .013). Among TMD patients, those categorized as TMP exhibited the highest scores in the physical pain (P = .02) domain. Previous orthodontic treatment, comorbid headache and body pain, limitations in mouth opening and lateral movement, pain, and muscle tenderness scores were found to be strongly related to the OHIP-14. TMD patients suffered from impaired OHRQoL considerably more than controls. OHRQoL in TMD patients is a multidimensional phenomenon influenced by previous orthodontic treatment, comorbid symptoms, pain, functional limitations, and muscle tenderness scores.

    The aim of this study was to determine whether T.M.J. tomographic examination yielded significant difference in condyle positions among asymptomatic, myalgia, derangement, and arthrosis group of T.M.J. disorders. The author obtained sagittal linear tomograms of right and left T.M.Js. of 36 asymptomatic, 22 myalgia, 54 derangement, and 31 arthrosis patients taken at serial lateral, central, and medial sections in the intercuspal position after submentovertex radiographs analyzed. With the dual linear measurements of the posterior and anterior interarticular space, condyle positions were mathematically expressed as proportion. All data from these analysis was recorded and processed statistically. The results were obtained as follows: 1. In asymptomatic group, radiographically concentric condyle position was found in 50.0% to 65.4% of subjects, with a substance range of variability. No significant differences existed between men and women and also between right and left T.M.Js. for condyle position. 2. In women, significant difference for mean condyle position of left lateral section of each diagnostic category existed between derangement and myalgia groups (P< .05). Also that of left central section existed between derangement and myalgia group, and that of left medial section existed between derangement and myalgia groups (P< . 05). 3. In main-symptom side, condyle position in myalgia group was more concentric, and condyle position in derangement and group was more posterior. This showed significant differences between derangement and myalgia groups in lateral, central, and medial sections of main symptom side, and only between derangement and myalgia groups in central section of contra-lateral sides (P< .05). Condyle position in arthrosis group was broadly distributed among all positions. 4. In contra-lateral side, significant difference for mean condyle position of central section of each symptomatic group existed between derangement and myalgia group (P< .05

    Full Text Available Obesity and depression represent a growing health concern worldwide. For many years, basic science and medicine have considered obesity as a metabolic illness, while depression was classified a psychiatric disorder. Despite accumulating evidence suggesting that obesity and depression may share commonalities though, the causal link between eating and mood disorders remains to be fully understood. This etiology is highly complex, consisting of multiple environmental and genetic risk factors that interact with each other. In this review, we sought to summarize the preclinical and clinical evidence supporting a common etiology for eating and mood disorders, with a particular emphasis on signaling pathways involved in the maintenance of energy balance and mood stability, among which orexigenic and anorexigenic neuropeptides, metabolic factors, stress responsive hormones, cytokines and neurotrophic factors.

    The aim of this study was to evaluate changes in the trabecular structure of the mandibular condyle in patients with temporomandibular disorders (TMDs) using fractal analysis. A total of 100 patients ages 18 to 73 years were clinically assessed using the Diagnostic Criteria for Temporomandibular Disorders. The control group was age- and sex-matched with the patient group. Panoramic radiographs were obtained using a Kodak 8000 digital device with 73 kVp and 5 mA fixed parameters. The degree of degeneration in the mandibular condyles was calculated. Regions of interest (84 × 84 pixels) were selected within the cortical boundary of the mandibular condyle, and the fractal dimension (FD) was calculated using ImageJ version 1.48. Radiographic degenerative changes were more frequently present and more severe in the patient group (P temporomandibular joints of the patient group, whereas a nonsignificant decrease in FD was observed in the right temporomandibular joints (P = .073) as degenerative changes increased. Lower FD values were associated with more severe degenerative changes in the patient group. The trabecular structure of condyles in patients with TMD exhibited decreased complexity when erosive and sclerotic changes were evident. As a result, fractal analysis enhanced the use of panoramic radiography in detecting degenerative changes in patients with TMD. Copyright © 2016 Elsevier Inc. All rights reserved.

    Lymphadenopathy often occurs in the setting of inflammation, with or without infection. We sought to elucidate any association of parotid lymphadenopathy with joint effusion in temporomandibular joint (TMJ) disorders. We performed a retrospective cohort study. We analyzed the magnetic resonance imaging studies of patients with suspected TMJ disorders performed from April 2006 to March 2007. The degree of joint effusion was graded on sagittal T2-weighted spin echo images according to a commonly used system. On axial short T1-weighted short inversion recovery images, the number and short-axis diameter of the parotid lymph nodes were recorded. We performed analyses of the cluster-correlated data using the Mann-Whitney U test and Spearman's correlation coefficients. P disorders were analyzed from 201 patients during the study period. The number and size of the parotid lymph nodes identified was significantly greater in the patients with TMJ effusion (P disorders. These findings indicate that lymphadenopathy should be considered as an inflammation condition commonly associated with joint effusion in TMJ disorders.

    This study investigated a patient population suffering from temporomandibular disorders (TMD) with respect to their need for treatment, satisfaction with the information received, and the treatment provided. A survey was sent by post to 1011 patients. Almost one-third of the patients had used analgesics prior to the start of any treatment. Having pain and functional jaw complaints was a risk factor for patients experiencing social restrictions. Subjects with severe complaints needed a range of conservative treatment modalities in combination with more follow-up appointments in agreement with the practitioners. Persons with remaining functional limitations were often unsatisfied with information and care they had received. The rate of compliance with prescribed treatment modalities and advice corresponded significantly higher with patient contentment with final outcome. Patient satisfaction is often determined by a qualitative doctor-patient relationship. The influence of complaints and pain on daily functioning was illustrated. Pain medication use at baseline seems to be predictive for persistent orofacial pain (OFP).

    Pain-related temporomandibular disorder (TMD) is one of the top three most common chronic pain conditions, along with headaches and back pain. TMD has complex pathophysiology and significant associations with a variety of other chronic pain conditions, eg fibromyalgia, irritable bowel syndrome and migraine. Chronic TMD is associated with a negative impact upon quality of life and high levels of healthcare utility. It is important that clinicians are able to diagnose TMD correctly, provide appropriate management in keeping with current evidence-based practice, and identify when to refer patients to specialist care. The presence of risk factors, eg anxiety, depression, pain-related disability and chronic pain conditions elsewhere in the body, may help to identify which TMD patients require referral for multidisciplinary management. TMD should be managed using a holistic approach, incorporating patient education and encouragement towards self-management. TMD care pathways should consider using the three'pillars'of pain management: physical therapies, pharmacotherapy and clinical psychology.

    Full Text Available The possible association between orthodontic treatment and temporomandibular disorders (TMD is a topic of great interest in the current literature. The true role of orthodontic therapy on the etiology of TMD, however, is still uncertain. From the clinical prospective, a thorough examination of the stomatognathic system is always necessary in order to detect possible TMD signs and symptoms prior to the beginning of the orthodontic therapy. Caution should be exercised when planning, performing and finalizing orthodontics, especially in patients who with history of signs and symptoms of TMD. The clinician must always eliminate patient's pain and dysfunction before initiating any type of orthodontic mechanics. Muscle incoordination, unstable disc-condyle relationship and bone alterations are usual TMD conditions that can interfere with the presenting occlusal relationship. This article reviews these aspects and presents a detailed clinical guide for the examination of the orthodontic patient, considering aspects related to facial pain and dysfunction.

    The aim of this study was to investigate the relationship between orientation of craniofacial planes relative to the true horizontal and temporomandibular disorder (TMD), in normal occlusion. Fourteen university dental students, with full natural dentition and bilateral Angle Class I occlusion, who exhibited signs and symptoms of TMD, were compared with 14 age- and sex-matched healthy controls. Frontal and lateral photographs were taken in natural head position with the subject standing up, clenching a Fox plane and having a facial arch positioned. Photographs were examined by a standardized image analysis. Inter-pupillary axis, Frankfurt, occlusal and Camper planes were evaluated. In frontal view, the Frankfurt plane was right rotated relative to the true horizontal both in TMD subjects (P weak association exists between the orientation of craniofacial planes in natural head position and signs and symptoms of TMD. Furthermore, they suggest that, within this population, TMD might be mainly associated with head posture rather than with craniofacial morphology.

    Trismus is a restriction in the ability to open the mouth. Trismus can occur following trauma, surgery, radiation therapy, infection, inflammatory diseases, temporomandibular disorders (TMD) or less commonly as a result of malignancy. Following two cases of delayed diagnosis of carcinoma presenting with features of TMD to a specialist clinic, a checklist was developed for completion in cases of trismus, to alert the clinician to suspicious features suggesting a possible non-TMD cause. The use of this checklist, together with an increased awareness, has improved early recognition of atypical features in patients presenting with trismus and has contributed to the early diagnosis of a further case of malignancy presenting to this clinic. This article discusses the presentation of malignancy with trismus, the relevance of imaging in these cases, and the implementation of a checklist to reduce the risk of future misdiagnosis.

    This article reports the case of a 19-year-old young man with Class III malocclusion and posterior crossbite with concerns about temporomandibular disorder (TMD), esthetics and functional problems. Surgical-orthodontic treatment was carried out by decompensation of the mandibular incisors and segmentation of the maxilla in 4 pieces, which allowed expansion and advancement. Remission of the signs and symptoms occurred after surgical-orthodontic intervention. The maxillary dental arch presented normal transverse dimension. Satisfactory static and functional occlusion and esthetic results were achieved and remained stable. Three years after the surgical-orthodontic treatment, no TMD sign or symptom was observed and the occlusal results had not changed. When vertical or horizontal movements of the maxilla in the presence of moderate maxillary constriction are necessary, segmental LeFort I osteotomy can be an important part of treatment planning.

    The effect of Microcurrent Electrical Nerve Stimulation (MENS) was evaluated and compared with occlusal splint therapy in temporomandibular disorders (TMD) patients with muscle pain. Twenty TMD patients were divided into four groups. One received occlusal splint therapy and MENS (I); other received splints and placebo MENS (II); the third, only MENS (III) and the last group, placebo MENS (IV). Sensitivity derived from muscle palpation was evaluated using a visual analogue scale. Results were submitted to analysis of variance (p<0.05). There was reduction of pain level in all groups: group I (occlusal splint and MENS) had a 47.7% reduction rate; group II (occlusal splint and placebo MENS), 66.7%; group III (MENS), 49.7% and group IV (placebo MENS), 16.5%. In spite of that, there was no statistical difference (analysis of variance / p<0.05) between MENS and occlusal splint therapy regarding muscle pain reduction in TMD patients after four weeks.

    Introduction. Psychosocial and somatosensory factors are involved in the pathophysiology of chronic migraine (CM) and chronic temporomandibular disorders (TMD). Objective. To compare and assess the relationship between pain catastrophizing and kinesiophobia in patients with CM or chronic TMD. Method. Cross-sectional study of 20 women with CM, 19 with chronic TMD, and 20 healthy volunteers. Pain catastrophizing and kinesiophobia were assessed. The level of education, pain intensity, and magnitude of temporal summation of stimuli in the masseter (STM) and tibialis (STT) muscles were also evaluated. Results. There were significant differences between the CM and chronic TMD groups, compared with the group of asymptomatic subjects, for all variables (p kinesiophobia when comparing patients with CM and healthy women. Moderate correlations between kinesiophobia and catastrophizing (r = 0.46; p kinesiophobia and magnification (r = 0.52; p kinesiophobia between women with CM and with chronic TMD. Women with CM or chronic TMD showed higher levels of pain catastrophizing than asymptomatic subjects. PMID:27818609

    Using reconstructed three-dimensional computed tomography (3D-CT) models, the purpose of this study was to analyze and compare mandibular condyle morphology in patients with and without temporomandibular disorder (TMD). Thirty-two patients were divided into two groups: the first comprised those with TMD (n=18), and the second those who did not have TMD (n=14). A CT of each patient was obtained and reconstructed as a 3D model. The 64 resulting 3D condylar models were evaluated for possible TMD-associated length, width and height asymmetries of the condylar process. Descriptive statistics were used to assess the results and student' s t tests applied to compare the two groups. Statistically significant (pasymmetries of the condylar process were observed between TMD and non-TMD groups. TMD patients showed less condylar height (p3D-CT, it was shown that condylar width, height and length asymmetries were a common feature of TMD.

    The aims of the current study were: (1) to assess the prevalence of oral habits, bruxism, and temporomandibular disorders (TMDs) among children living in Uganda; (2) to establish whether parafunctional activities are associated with TMDs; and (3) to examine the possible impact of gender and age on the prevalence of bruxism, oral habits, and TMDs. This study included 153 children aged 6-17 years. The study consisted of a questionnaire and a clinical examination. TMDs were moderately prevalent (35%). Parafunctional habits were performed by 93% of the participants. When performed extensively, they were significantly related to myalgia. No gender or age significant differences were found. 1. Only extensive masticatory parafunctional oral activity is significantly related to myalgia. 2. Gender and age had no impact on the prevalence of bruxism, oral habits, or TMDs. 3. Sleep and awake bruxism were not related to anamnestic symptoms or clinical findings in TMD.

    To evaluate the relationship between temporomandibular disorders (TMD) and craniocervical posture in the sagittal plane measured from lateral radiographs of the head. The sample was comprised of 80 randomly selected students of dentistry at the Federal University of Rio Grande do Norte. Research Diagnostic Criteria for TMD (RDC/TMD) was used to evaluate the signs and symptoms of TMD. Lateral radiographs of each individual were used to measure the position of the hyoid bone, the craniocervical angle, and the occiput-atlas distance. A chi-square test was used to evaluate the relationships between craniocervical posture measures and TMD. No relationship was found between TMD and the craniocervical posture measured by the positioning of the hyoid bone, head rotation, and the extension/flexion of the head (p > 0.05). It can be concluded, therefore, that no relationship exists between cervical posture in the sagittal plane and TMD.

    Full Text Available Paroxysmal hemicrania (PH is a trigeminal autonomic cephalalgia, a rare primary headache characterized by unilateral periorbital and/or temporal attacks of severe intensity and short duration. In this situation, the determination of a correct diagnosis is crucial for the establishment of a proper management strategy. In the case of head and facial pain, this step is usually a big challenge since many conditions share the same features, as some primary headaches and temporomandibular disorders (TMD. The relationship between PH and TMD has not been determined. This paper describes a case of a female patient diagnosed with TMD and presenting concomitant headache attacks fulfilling the International Headache Society′s criteria for PH. It is also emphasized the importance of dentist in this scenario, for many times responsible for the initial diagnosis of facial/head pain. Moreover, it is presented an integrated and simultaneously approach of both conditions, PH and TMD.

    Temporomandibular Disorder (TMD) is a term generally applied to a condition or conditions characterized by pain and/or dysfunction of the masticatory apparatus. Its characterization has been difficult because of the large number of symptoms and signs attributed to this disorder and to variation in the number and types manifested in any particular patient. For this study, data on 4,528 patients, presenting over a period of 25 years to a single examiner for TMD treatment, was made available for retrospective analysis and determination of whether the TMD care-seeking patient can be profiled, particularly pain difficulties. All patients in this database filled out a questionnaire and were examined for the prevalence of a range of symptoms and clinical examination findings (signs) commonly attributed to TMD. There was no attempt in this study to assign patients to TMD diagnostic subcategories. The data collected were analyzed to determine which of these symptoms and signs were sufficiently "characteristic of the TMD condition" that they might be used in diagnosis, research and treatment, especially in patients needing relief from pain and discomfort. All 4,528 patients reported symptoms and all but 190 of them also showed signs upon examination. Symptoms most commonly reported on the questionnaire included (i) pain (96.1%), (ii) headache (79.3%), (iii) temporomandibular joint discomfort or dysfunction (75.0%) and (iv) ear discomfort or dysfunction (82.4%). In the 4,338 patients who showed signs, the most prevalent was tenderness to palpation of the pterygoid muscles (85.1%), followed by tenderness to palpation of the temporomandibular joints (62.4%). Pain symptoms and signs were often accompanied by compromised mandibular movements, TMJ sounds and dental changes, such as incisal edge wear and excessive overbite. Clearly prevalence of pain disclosed by the symptoms and signs examinations was high. Patients showed variable prevalence and nonprevalence of eight categories

    Temporomandibular disorders (TMD) are recognized as one of the most controversial topics in dentistry, despite the fact that both basic science and clinical researchers have currently reached some degree of consensus. This study aimed to conduct a questionnaire-based survey about the management of TMD patients by general dental practitioners (GDPs). One hundred fifty-one GDPs with a private practice in a city of southern Brazil were included, independent of school of origin, gender, graduation year, and curriculum content. All participants were administered a questionnaire about the management of patients with TMD, and the responses were analyzed by binomial and chi-square tests (α = 0.05). Of the GDPs, 88.7% received TMD patients, who were primarily diagnosed on the basis of medical history (36.6%) or physical examination (30.4%). Of these, 65.4% referred the patients elsewhere, primarily to specialists in occlusion (36.1%) or orthodontics (29.7%). Occlusal splinting was the most commonly used management modality (20.8%), followed by occlusal adjustment (18.1%) and pharmacotherapy (16.6%). Splints were fabricated in maximum habitual intercuspation or centric relation depending on individual patient (54.8%). The hard stabilization form was the most common type of appliance used (35.0%). Moreover, 73.8% of the GDPs did not employ semi-adjustable articulators, and 69.5% adjusted the appliances at the time of fixing. The duration of splint use and the frequency of follow-up were considered patient dependent by 62.1% and 72.8%, respectively. GDPs considered the two major TMD etiologic categories as multifactorial (20.8%) and occlusion (19.9%). Multidisciplinary medical and dental treatment was considered necessary by 97.9%. The evaluated general dental practitioners manage TMD patients according to international guidelines. © 2015 by the American College of Prosthodontists.

    The purpose of this study was to address the following question: among patients with acute or chronic temporomandibular disorders (TMD), does low-level laser therapy (LLLT) reduce pain intensity and improve maximal mouth opening? The sample comprised myogenic TMD patients (according Research Diagnostic Criteria for TMD). Inclusion criteria were: male/female, no age limit, orofacial pain, tender points, limited jaw movements and chewing difficulties. Patients with other TMD subtypes or associated musculoskeletal/rheumatologic disease, missing incisors teeth, LLLT contra-indication, and previous TMD treatment were excluded. According to disease duration, patients were allocated into two groups, acute (TMD (≥ 6 months). For each patient, 12 LLLT sessions were performed (gallium-aluminum-arsenide; λ = 830 nm, P = 40 mW, CW, ED = 8 J/cm(2)). Pain intensity was recorded using a 10-cm visual analog scale and maximal mouth opening using a digital ruler (both recorded before/after LLLT). The investigators were previously calibrated and blinded to the groups (double-blind study) and level of significance was 5% (p TMD), and 26 (chronic TMD). Both groups had a significant pain intensity reduction and maximal mouth opening improvement after LLLT (Wilcoxon test, p TMD patient had a more significant pain intensity reduction (Mann-Whitney test, p = 0.002) and a more significant maximal mouth opening improvement (Mann-Whitney test, p = 0.011). Low-level laser therapy can be considered as an alternative physical modality or supplementary approach for management of acute and chronic myogenic temporomandibular disorder; however, patients with acute disease are likely to have a better outcome.

    When a dysfunction occurs in any component of the stomatognathic system, temporomandibular disorders (TMD) may originate. The aim of this study was to compare the deviations, displacement and the execution speed of mandibular movements among asymptomatic participants and those with TMD. Convenience sampling was used; forty participants diagnosed by clinical evaluation following the Research Diagnostic Criteria for Temporomandibular Disorders were divided into three groups: arthropathy (GART, 10 participants, 40% men), myopathy (GMYO, 10 participants, 30% men), and the control group (CG, 20 asymptomatic participants, 25% men). Participants were asked to perform the movements of free maximal mouth opening and closing, right and left lateral excursions, and protrusion with sliding teeth contacts. The mandibular trajectory was recorded using opto-electronic devices tracking reflective markers placed in front of the 'soft tissue pogonion point'. The movements were analysed on the following axis: x - medial-lateral, y - vertical, z - antero-posterior. Significative differences were found in CGxGART - unassisted maximal mouth opening and closing projection on y-axis (OCY), CGxGMYO - unassisted maximal mouth opening and closing projection on x-axis (OCX), and in the measures Opening lateral deviation on x-axis (OLDX), closing lateral deviation on x-axis (CLDX) and in the measures of speed for both. In regard to GARTxGMYO, a significative difference was found in Protrusion lateral deviation on x-axis (PLDX) 'Conover-Iman Test of Multiple Comparisons Using Rank Sums' using Bonferroni correction (P < 0·05). In conclusion, the total opening movements in individuals with TMD tended to have higher deviation than in those asymptomatic individuals and a reduction in the speed of movements. © 2017 John Wiley & Sons Ltd.

    Pain-related temporomandibular disorders (TMDs) are the most prevalent conditions among TMDs. There is contrasting evidence available for association of pain-related TMD and masticatory muscle activity (MMA). The present investigation assesses the associations between MMA levels of masseter and temporalis muscles during awake and sleep among pain-related TMD diagnostic groups. The department of Oral Diagnostic Sciences, University at Buffalo. Twenty females and six males participated in this study. Using the diagnostic criteria for temporomandibular disorders (DC-TMDs), participants were diagnostically categorized. Subjects used a custom monitoring system, which recorded infield muscle activities. A factorial model tested for association between independent variable (muscle, time period, MMA level, and diagnostic group) effects and the logarithm of MMA. Greenhouse-Geisser test was used to determine any statistically significant associations (p≤0.003). No statistically significant association was found between four-way, three-way, and two-way analyses. However, among the main effects, range of magnitudes was the only variable to be statistically significant. Although the data suggest a trend of increased masseter MMA in the pain-related TMD diagnoses group both during awake and sleep time periods, such observation is not maintained for the temporalis muscle. In addition, temporalis MMA was found to be higher in the pain-related TMD diagnoses group only at extreme activity levels (<25 and ≥80% ranges). This data support the association between masticatory muscle hyperactivity and painful TMD conditions. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The aim of this study is to assess the prevalence of temporomandibular disorders (TMDs) among university students. The etiology of TMD is of multifactorial, and our study is designed to assess the prevalence of TMD in an institution within a university. Various parameters including trauma, malocclusion, stress assessment - its correlation with the timing, the duration of TMD in meeting the deadlines, and examinations have been assessed. A standard questionnaire-based study with modified Fonseca anamnestic index is used. The questionnaire study was conducted with a statistically calculated sample size of 402 students within a university. The data were analyzed statistically for significance and correlations. Statistical analysis was performed using SPSS for Windows release 14.0 (SPSS Inc., Chicago, IL, USA). Differences at the 5% level were accepted as being statistically significant. TMD and its associated symptoms are frequent among students of health and science studies. Female predominance is seen. There was also an increased prevalence of symptoms in people who described themselves as being tense. The relationship between orthodontic therapy and TMDs were also evaluated, and the duration of therapy is found to be significant. There was a significant association between history of trauma and presence of TMDs. TMD and its associated symptoms are frequent among students of health and science studies. A simple anamnestic index is of use in identifying and classifying temporomandibular joint and TMD symptoms in patients according to the severity of the disorder. Females showed a greater prevalence of signs and symptoms of TMD than males. Longitudinal studies are recommended to identify and follow-up the prevalence and health-care needs of patients with TMDs.

Five hundred and forty-seven students aged 8-14 years were recruited from public schools in Piracicaba, Brazil. Self-perceptions of QoL were measured using the Brazilian Portuguese versions of Child Perceptions Questionnaires (CPQ)8-10 (n = 247) and CPQ11-14 (n = 300). A single examiner, trained and calibrated for diagnosis according to the Axis I of the Research Diagnostic Criteria for TMD (RDC/TMD), examined the participants. A self-report questionnaire assessed subjective symptoms of TMD. Intraexaminer reliability was assessed for the RDC/TMD clinical examinations using Cohen's Kappa (κ) and intraclass correlation coefficient (ICC). Criterion validity was calculated using the Spearman's correlation, construct validity using the Spearman's correlation and the Mann-Whitney test, and the magnitude of the difference between groups using effect size (ES). Reliability was determined using Cronbach's alpha, alpha if the item was deleted and corrected item-total correlation. Intraexaminer reliability values ranged from regular (κ = 0.30) to excellent (κ = 0.96) for the categorical variables and from moderate (ICC = 0.49) to substantial (ICC = 0.74) for the continuous variables. Criterion validity was supported by significant associations between both CPQ scores and pain-related questions for the TMD groups. Mean CPQ8-10 scores were slightly higher for TMD children than control children (ES = 0.43). Preadolescents with TMD had moderately higher scores than the control ones (ES = 0.62; p temporomandibular disorder.

    The aim of this study was to evaluate the association between self-reported sleep bruxism and the age, gender, clinical subtypes of temporomandibular disorders (TMD), pain intensity and grade of chronic pain in patients previously diagnosed with TMD. Thousand two-hundred and twenty patients of the Andalusian Health Service were examined using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire. The inclusion and exclusion criteria were those included in the RDC/TMD criteria. The bruxism diagnosis was drawn from the question, 'Have you been told, or do you notice that you grind your teeth or clench your jaw while sleeping at night?' in the anamnestic portion of the questionnaire. A bivariate analysis was conducted, comparing the presence of perceived parafunctional activity with age (over age 60 and under age 60), gender, different subtypes of TMD, pain intensity, grade of chronic pain and presence of self-perceived locked joints. The overall prevalence of self-reported sleep bruxism (SB) was 54.51%. A statistically significant association was found between the presence of SB and patients under age 60, women, greater pain intensity, greater pain interference with activities of daily living, and the axis-I groups affected by both muscular and articular pathology. There is a statistically significant association between self-reported sleep bruxism and women under age 60 who have painful symptoms of TMD. There is also a positive association between this parafunctional habit and the presence of chronic pain. However, more studies that cover larger samples and differentiate between sleep bruxism and awake bruxism are needed. © 2014 John Wiley & Sons Ltd.

    Full Text Available INTRODUCTION: Temporomandibular disorders (TMD have proved to be a risk factor for developing hyperdivergent facial growth patterns. OBJECTIVE: The aims of this study were: (1 Assess differences between the cephalometric measurements in children with articular TMD and a control group, before and after mandibular growth peak according to cervical vertebral maturation; and (2 Identify a predictive model capable of differentiating patients with TMD and control group patients based on early cephalometric characteristics. METHOD: The study included children and adolescents with maximum age of 17 years, divided into experimental group (n=30 diagnosed with articular TMD-according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD for children and adolescents-subdivided according to growth stage, called pre-peak (n=17 and post-peak (n=13 and control group (n = 30, matched by gender, skeletal maturity stage of the cervical vertebrae and classification of malocclusion. Lateral cephalometric and craniofacial structures were traced and their relations divided into: Cranial base, maxilla, mandible, intermaxillary relations, vertical skeletal relations and dental relations. Differences between the means for each variable were evaluated by applying the statistical Student t test for independent samples. RESULTS: The means of the variables analyzed in the pre-peak showed no statistically significant differences. However, analysis of post-peak showed that the experimental group displayed decreased SNA and SNB and increased SN.Gn and 1.NB (p<0.05. CONCLUSION: It was possible to identify a predictive model able to differentiate patients with TMD and asymptomatic controls from early cephalometric characteristics.

    Considering the high incidence of Temporomandibular Disorders (TMD) in the population aged 15-30 years and the fact that students are exposed to stressful psychosocial factors, the purposes of this study were: to verify clinical symptoms and jaw functionality in college students with TMD according to the anxiety/depression (A/D) level and to evaluate the correlation between A/D and functionality, maximum mouth opening (MMO) and pain and muscle activity. Nineteen students with TMD diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders underwent two assessments during an academic semester. The evaluations were based on questionnaires (MFIQ - Mandibular Function Impairment Questionnaire; HADS - Hospital Anxiety and Depression Scale), clinical measurements (MMO without pain, MMO and assisted MMO; palpation of joint and masticatory muscles), and electromyography. The HADS scores obtained in the two assessments were used to classify all data as either "high" or "low" A/D. Data normality, differences and correlations were tested with the Shapiro-Wilk test, Student's t-test (or the Wilcoxon test), and Spearman test, respectively. The alpha level was set at 0.05. None of the clinical variables were significantly different when comparing low and high A/D data. In low A/D there was a significant correlation between HADS score and: MFIQ (P=0.005, r=0.61), and MMO without pain (P=0.01, r=-0.55). Variation in A/D level did not change clinical symptoms or jaw functionality in college students with TMD. Apparently, there is a correlation between TMJ functionality and A/D level, which should be further investigated, taking into account the source of the TMD and including subjects with greater functional limitation.

    The aim of this study was to investigate dentist's approaches to the use of splint therapy for myofascial pain, bruxism, and temporomandibular joint (TMJ) disorders and to assessment of treatment modalities. A 12-item questionnaire was developed to determine dentists' knowledge of TMJ disorders and approaches for occlusal splint treatments. The researchers spoke with each dentist included in the study at his/her clinic or by telephone to assess their immediate knowledge and approach to the TMJ disorders. Chi-squared test was performed to analyze the values. The confidence interval was set as 95%. A total of 370 dentists working in Turkey were participated in this study. The most common splint application reason for occlusal splint treatment was bruxism (77.8%) while TMJ pain was very rare (%1.4). The use of hard splint ratios for 0-5 years of professional experience was 57.0%, 42.4.0%, and 26.8% for the experience of 5-15 years and over 15 years groups, respectively (P < 0.001). While the dentists' with sufficient knowledge soft splint application rates were 11.6%, hard splint application rates were 43.4% for the dentists with sufficient knowledge. Occlusion adjustment rate of dentists who practice in all three groups was under 16.0%. The knowledge of the dentists about TMJ disorders and occlusal splint therapy were found to be insufficient. Their knowledge decreased with increasing experience.

    This study aims to investigate the risk factors of temporomandibular disorders (TMDs), including disc or non-disc-related disorders, and joint hypermobility syndrome (JHS) retrospectively and to analyze the factors by estimating the magnitude of the association between the two conditions using a nationwide population-based dataset. A total of 975,788 eligible patients' de-identified data were obtained from a representative database composed of one million of Taiwan's population since 2004 to 2008. All associated factors, such as gender, age, facial trauma, and psychosis, which correlated with TMDs and JHS were examined. Multiple logistic regression modeling adjusted for confounding variables to determine the odds ratio of variables that made an important contribution to TMDs and JHS. For all TMDs patients, only 1.47% patients had disc-related disorders. For all JHS patients, only 3.85% patients are diagnosed with concomitant TMDs. Statistically significant association was observed between joint hypermobility and TMDs. Furthermore, the prevalence of JHS patients shows significant difference within TMD subgroups, in which 9.52% of JHS patients have disc disorders and 90.48% of JHS patients do not. All associated factors, such as gender, age, JHS, facial trauma, and psychosis, had a significant impact on the TMDs. Interestingly, patients with TMJ articular disc disorders are 6.7 times more likely to be diagnosed with JHS compared to patients without disc-related disorders. Our results confirm that there is a significant positive association between TMDs and JHS, highlighting that patients with disc-related TMDs are more likely to experience JHS than patients with TMDs without disc disorders. Individuals with TMD associated with JHS should be carefully evaluated by inter-disciplinary specialists as these factors may eventually have impact on the prognosis of TMDs and JHS.

    Since the description of athetosis in 1871 by American neurologist William Alexander Hammond (1828-1900) the disorder has been a source of controversy, as were many aspects of Hammond's career. Primary sources have been used to review controversies in the 50-year period since the initial description of athetosis, in particular those concerning clinical features, differentiation from other movement disorders, associated conditions, and pathology. Controversies concerning treatment will be addressed in a subsequent article. Hammond struggled to establish athetosis as a distinct clinical-pathological entity, and had successfully predicted the striatal pathology in his initial case (albeit somewhat serendipitously). Athetosis was, nevertheless, considered by many neurologists to be a form of post-hemiplegic chorea or part of a continuum between chorea and dystonia. European neurologists, and particularly the French, initially ignored or discounted the concept. Additional controversies arose over whether the movements persisted during sleep, whether athetosis was, or could be, associated with imbecility or insanity, and how it should be treated. Some controversies concerning athetosis served to identify areas where knowledge was insufficient to make accurate statements, despite prior self-assured or even dogmatic statements to the contrary. Other controversies illustrated established prejudices, even if these biases were often only apparent with the greater detachment of hindsight.

    The purpose of the present study was to compare craniofacial morphology and bite force of bruxist patients with signs and symptoms of temporomandibular disorders. Fourteen subjects with sleep bruxism and 14 healthy subjects participated. The signs and symptoms of the temporomandibular disorders were identified according to the Craniomandibular Index (CMI). Maximum bite force was measured using strain-gage transducers. Lateral cephalometric films were taken, and linear and angular measurements were performed. Bite force between bruxist and non-bruxist females was not significant, whereas males with bruxism revealed higher bite forces. None of the linear and angular measurements differed significantly between bruxist and non-bruxist males. However, higher mandibular corpus length and anterior cranial base length, and lower gonial angle were observed in bruxist females compared to non-bruxist females. Negative correlation between bite force and CMI values was found in both genders. Bruxist females had higher CMI values than bruxist males, which could lead to relatively lower bite forces.

    To investigate the clinical effects of laser acupuncture therapy for temporomandibular disorders (TMD) after ineffective previous treatments. A retrospective observational study was conducted in 29 treatment-resistant TMD patients (25 women, 4 men; age range, 17-67 years). Subjects were treated 3 times per week for 4 weeks with the Handylaser Trion (GaAlAs laser diode, 810 nm, 150 mW, pulsed waves), which delivered 0.375 J of energy (5 s) to ST7, ST6, and LI4 and 3 J (40 s) to each Ashi point, 7.5-26.25 J/cm2 in total. The visual analog scale (VAS) and maximal mouth opening (MMO) were evaluated before and after treatment. VAS analysis showed that the patients were free of pain at rest (endpoint) after 5.90±6.08 sessions of laser acupuncture for acute TMD and after 16.21±17.98 sessions for chronic TMD. The VAS score on palpation of the temporomandibular joint reduced to 0.30±0.67 for patients with acute TMD (p = 0.005) and to 0.47±0.84 for those with chronic TMD (pTMD (7.80±5.43 mm, p = 0.008) and in patients with chronic TMD (15.58±7.87 mm, ptreatment-resistant TMD. Further studies with a more appropriate design, involving long-term follow-up examinations in a larger patient sample, are needed to evaluate its efficacy.

    Temporomandibular joint disorder (TMD) is a general term for diseases of the temporomandibular joint and orofacial muscles. In this study, we tested whether laser acupuncture was effective for the treatment of TMD. Twenty patients with TMD were treated with diode K-Laser (wavelength 800 nm, energy density 100.5 J/cm(2)) once a week at four acupuncture points including three standard ipsilateral local points (ST6, ST7, Ashi point) and one contralateral distal point (LI4). A 10-cm visual analogue scale (0 no pain and 10 the most severe pain) was used for measuring the pain intensity before and after the treatment. Seventeen out of 20 patients (85%) showed various degrees of pain relief after laser acupuncture treatment. The average pain score was 6.3 ± 1.6 before treatment and 2.5 ± 2.2 after treatment. Significant pain relief after laser acupuncture treatment was achieved (p = 0.0003, Wilcoxon signed rank test). The 17 patients showed an average pain relief of 63 ± 31%. There were six patients who showed no TMD symptoms after an average of four treatments of laser acupuncture. The other 11 patients showed partial relief of TMD symptoms after treatment. Although the pain was still present, it was less and was acceptable. No side effects were reported in any patients during or after laser acupuncture treatments. Laser acupuncture may be an alternative treatment modality for TMD because it is non-invasive, results in partial or total relief of pain, and has no side effects. Copyright © 2012.

    The aim of this study was to assess the prevalence and severity of temporomandibular joint disorders (TMDs) among undergraduate medical students in the presence of khat chewing over a period of time. Totally, 186 medical college students (age Fonseca's anamnestic index and its questionnaire, which is composed of 10 questions and classifies the severity of TMDs. The obtained data were coded and entered into Statistical Package for the Social Sciences (SPSS) program for analysis using chi-square test at significance level of 5%. Most of the participants were male (68.8%) students and older than 20 years (63%). Those who reported with khat chewing comprised 31.7%. From the total samples, only 38.0% was classified as having mild TMD and 0.50% were classified as having severe TMD. Poor dental articulation, grinding of teeth, headaches, tense personalities, and temporomandibular joint (TMJ) clicking were the most common clinical findings. The mean scores showed no significant difference among gender (p < 0.29) and the khat chewing (p < 0.531) groups for the 10 questions. However, it showed significant difference among age groups (p < 0.025). The majority of subjects complained of mild TMD, while only a few cases showed a moderate TMD among different age groups. The most frequently reported dysfunctions were related to poor dental articulation and grinding of the teeth, frequent headaches, the clicking of joint, and tense personalities. No significant difference was found between gender and khat and nonkhat chewing groups. Khat chewing is a parafunctional habit and affects dental occlusion (especially cuspal wear) in terms of anterior guidance. Such alterations in occlusion are known to be one of the causative (predisposing) factors of TMD.

    This study investigated the applicability of a Bayesian belief network (BBN) to MR images to diagnose temporomandibular disorders (TMDs). Our aim was to determine the progression of TMDs, focusing on how each finding affects the other. We selected 1.5-T MRI findings (33 variables) and diagnoses (bone changes and disc displacement) of patients with TMD from 2007 to 2008. There were a total of 295 cases with 590 sides of temporomandibular joints (TMJs). The data were modified according to the research diagnostic criteria of TMD. We compared the accuracy of the BBN using 11 algorithms (necessary path condition, path condition, greedy search-and-score with Bayesian information criterion, Chow-Liu tree, Rebane-Pearl poly tree, tree augmented naïve Bayes model, maximum log likelihood, Akaike information criterion, minimum description length, K2 and C4.5), a multiple regression analysis and an artificial neural network using resubstitution validation and 10-fold cross-validation. There were 191 TMJs (32.4%) with bone changes and 340 (57.6%) with articular disc displacement. The BBN path condition algorithm using resubstitution validation and 10-fold cross-validation was >99% accurate. However, the main advantage of a BBN is that it can represent the causal relationships between different findings and assign conditional probabilities, which can then be used to interpret the progression of TMD. Osteoarthritic bone changes progressed from condyle to articular fossa and finally to mandibular bone contours. Disc displacement was directly related to severe bone changes. Early bone changes were not directly related to disc displacement. TMJ functional factors (condylar translation, bony space and disc form) and age mediated between bone changes and disc displacement.

    It is not known whether bone scan is useful for the prediction of the prognosis of patients with temporomandibular disorders (TMD). The aim of the present study was to identify useful prognostic markers on bone scan for the pre-therapeutic assessment of patients with unilateral TMD. Between January 2005 and July 2007, 55 patients (M:F=9:46; mean age, 34.7{+-}14.1 y) with unilateral TMD that underwent a pre-therapeutic bone scan were enrolled. Uptake of Tc-99m HDP in each temporomandibular joint (TMJ) was quantitated using a 13X13 pixel-square region-of-interest over TMJ and parietal skull area as background. TMJ uptake ratios and asymmetric indices were calculated. TMD patients were classified as improved or not improved and the bone scan findings associated with each group were investigated. Forty-six patients were improved, whereas 9 patients were not improved. There was no significant difference between the two groups of patients regarding the TMJ uptake ratio of the involved joint, the TMJ uptake ratio of the non-involved joint, and the asymmetric index (p>0.05). However, in a subgroup analysis, the patients with an increased uptake of Tc-99m HDP at the disease-involved TMJ, by visual assessment, could be easily identified by the asymmetric index; the patients that improved had a higher asymmetric index than the patients that did not improve (1.32{+-}0.35 vs. 1.08{+-}0.04, p=0.023), The Tc-99m HDP bone scan may help predict the prognosis of patients with unilateral TMD after splint therapy when the TMD-involved joint reveals increased uptake by visual assessment.

    Purpose This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. Materials and Methods The study subjects included 232 TMD patients. The inclusion criteria in this study were the presence of spontaneous pain or provoked pain on one or both temporomandibular joints (TMJs). The provoked pain was divided into three groups: pain on palpation (G1), pain on mouth opening (G2), and pain on mastication (G3). MRI examinations were performed using a 1.5-T MRI scanner. T1- and T2-weighted images with para-sagittal and para-coronal images were obtained. According to the T2-weighted image findings, the cases of effusions were divided into four groups: normal, mild (E1), moderate (E2), and marked effusion (E3). A statistical analysis was carried out using the χ2 test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Results Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (ppain, pain on palpation of the masticatory muscles and TMJ (G1) was not related to joint effusion in TMD patients (p>0.05). Conclusion Spontaneous pain was related to the MRI findings of joint effusion; however, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ was not related to the MRI findings of joint effusion. These results suggest that joint effusion has a significant influence on the prediction of TMJ pain. PMID:25473637

    To evaluate the association between signs of temporomandibular disorders (TMD) and psychological distress in a general population-based sample of Finnish adults. The Health 2000 Survey was conducted in 2000-2001 by the National Institute for Health and Welfare in Finland. Of the sample of adults aged 30 or over (n=8,028), 79% participated in a clinical oral health examination, which included examination of TMD signs. The participants (n=6,155) also completed questionnaires, including the 12-item General Health Questionnaire (GHQ-12), which measured psychological distress. Associations between TMD signs and psychological distress measured by the GHQ-12 were examined in both genders. Statistical measures included chi-square tests, t tests, and logistic regression analyses. The prevalence of the TMD signs (limited opening, clicking, crepitation, temporomandibular joint [TMJ] palpation pain, and muscle palpation pain) was 11.2%, 17.6%, 10.5%, 5.1%, and 18.9% in women, and 6.1%, 12.9%, 5.3%, 2.4%, and 7.2% in men, respectively. High GHQ-12 scores, measured as continuous variables and in quartiles by distress level, were significantly associated with masticatory muscle pain on palpation in both genders (PTMJ pain on palpation in women (PTMJ crepitation in men (Pmuscle pain on palpation both in women (odds ratio [OR]=2.18; 95% confidence interval [CI]=1.6-2.9) and men (OR=2.03; 95% CI=1.3-3.1). TMD signs and psychological distress appear to be associated. However, due to the limitations of the study, the findings can be regarded as preliminary.

    Temporomandibular disorders (TMD) can be related to self-reported musculoskeletal pains. The aim of the study was to investigate the association of clinical findings of TMD with self-reported pain in other parts of the body, and to discriminate pain clusters according to definite profiles of pain conditions including TMD among subjects in general population. A nationally representative Health 2000 Survey was carried out in 2000-2001 in Finland. The data were obtained from 6227 subjects aged ⩾30years. Information about pain in different parts of the body was collected from a questionnaire. The associations between clinically assessed TMD findings and pain in other areas were analyzed using chi-square test and logistic regression analyses. Latent class analysis (LCA) was used to form natural clusters, i.e., groups in which the individuals had similar profiles of pain conditions. Masticatory muscle pain on palpation associated with back, neck and shoulder pain and pain in joints. Temporomandibular joint (TMJ) pain on palpation associated with back, neck, shoulder and other joint pain. These associations did not change essentially after adjustment for confounders. After clustering of the study population with the LCA, 5.8% of the study population showed a multiple pain condition linked with TMD findings. Female gender, intermediate/poor self-reported health and presence of a longstanding illness increased the probability to belong to this cluster. TMD findings associate with pain in several locations. Female gender and presence of impaired health were particularly related to occurrence of multiple pain conditions.

    To investigate the influence of the presence of Temporomandibular Disorders (TMD) on postural balance in elderly individuals. The study sample consisted of 150 elderly: 103 women (67.7±5.0 years) and 47 men (69.3±5.5 years). Evaluation of the presence and severity of TMD included an anamnesis questionnaire, an evaluation of the temporomandibular joint (TMJ), and a muscular examination, which allowed the division of the elderly into 2 groups: G1 (experimental, n=95), with TMD; G2 (control, n=55), without TMD. Postural balance was assessed by means of the one-leg stance test (OLST) on a force platform (BIOMEC400), thus permitting the following measurements: center of foot pressure (COP); mean sway velocity (MV) and frequency (MF) of COP in both the anteroposterior (VAP and FAP) and medial/lateral (VML and FML) directions. The statistical analysis of data was performed using independent t-test, Variance Analysis, and Chi Square test (α=5%). Presence of TMD was observed in 63.3% of the individuals (Group 2), with different degrees of severity (mild: 42.7%, moderate: 14.7%, severe: 6%). Significantly higher TMD was observed for women (73.8%) compared with men (40.4%) (p=0.0002). No significant difference was found in between the groups for all balance parameters, e.g., presence and severity of TMD, presence of pain to palpation of TMJ and of masticatory and cervical muscles. The presence and severity of TMD, in addition to the presence of pain to palpation of TMJ and masticatory and cervical muscles did not alter the variables related to postural balance in this population.

    To evaluate the prevalence of self-reported bruxism and symptoms of temporomandibular disorders (TMD) and to investigate their association in academic and applied science university students in Finland. The data were gathered from 4,403 Finnish students included in the Finnish Student Health Survey 2012. The comprehensive questionnaire included five questions concerning bruxism and TMD symptoms. Bivariate associations between self-reported bruxism and TMD symptoms were evaluated using chi-square tests, and logistic regression model was used with age and gender as factors. Sleep bruxism was reported by 21.0% of women and by 12.5% of men, awake bruxism by 2.0% of women and by 2.8% of men, and both sleep and awake bruxism by 7.2% of women and by 3.2% of men. TMD pain was reported by 25.9% of women and by 11.4% of men and temporomandibular joint (TMJ) pain on jaw movement by 9.6% of women and by 4.2% of men. Report of sleep bruxism increased the risk for all TMD symptoms in both genders. Among women, report of awake bruxism increased the risk for TMD pain and TMJ pain on jaw movement. Reporting stress as a perpetuating factor for TMD pain increased the risk for both sleep and awake bruxism in both genders. The logistic regression analysis (including age and gender) showed that report of sleep bruxism and/or awake bruxism was associated with TMD pain (Odds Ratio [OR] = 5.71; 95% confidence interval [CI] = 4.86-6.70), TMJ pain on jaw movement (OR = 4.49; 95% CI = 3.54-5.69), and TMJ locking (OR = 2.98; 95% CI = 2.17-4.10). Bruxism and TMD symptoms are frequent in Finnish university students. Self-reported bruxism is associated with TMD symptoms, confirming earlier findings.

    The study aimed to examine possible time trends in the prevalence of clinical signs indicative of temporomandibular disorder (TMD) in an adult population, to analyse possible associations between TMD signs and associated factors and to estimate the need for TMD treatment. Three independent, stratified and randomly selected samples of around 100 individuals in the age groups of 20, 30, 40, 50, 60 and 70 years participated in the Jönköping studies in 1983,1993 and 2003. The study material consisted of 1,693 subjects who, after answering a questionnaire and being interviewed about the presence of TMD symptoms, were clinically examined in terms of the presence of TMD signs according to the Clinical Dysfunction Index (Di) by Helkimo. Associations between clinical signs and the Di as dependent variables and each of the independent variables of age group, gender, reported bruxism, trauma, self-perceived healthiness and the year of investigation were analysed in binary logistic regression models. Estimates of the need for TMD treatment were based on the presence of a combination of severe symptoms and clinical signs. The prevalence of severely impaired jaw movement capacity, relating to horizontal movements, had increased in 2003. The prevalence of muscle pain and temporomandibular joint pain upon posterior palpation was found to vary statistically significantly between 1993 and 2003. Gender differences were noted in these changes overtime. Female gender, advancing age, awareness of bruxism, self-perceived health impairment and the wearing of complete dentures were associated with TMD signs and a higher degree of clinical dysfunction. The estimated need for TMD treatment increased from 5% in 1983 to 8% in 2003 and was higher in women than in men. In conclusion, the results indicate that the prevalence of some TMD signs and of estimated treatment need increased during the period 1983-2003.

    Full Text Available Introduction The temporomandibular disorder (TMD consists of a set of signs and symptoms that affect the masticatory structures, which may cause joint and/or muscular pain. The physiotherapy approach aims at the pain relief and the functional recovery by means of several modalities.Objective To investigate the effects, short and medium-term, of a multimodal physiotherapeutic approach on TMD diagnosis and severity.Methodology Individuals with diagnosis of TMD, confirmed by the Axis I of the RDC/TMD, took part in the study. From this evaluation, the Temporomandibular Index (TMI and its sub-indices were calculated. The participants were treated during ten sessions of physiotherapy, which included therapeutic ultrasound, thermotherapy, manual therapy, stretching and neuromuscular exercises, as well as self-care and home exercises instructions. Assessments were carried out before treatment (AV1, immediately after treatment (AV2 and two months after the end of the treatment (AV3. The values of indices and the diagnosis prevalence were compared between the different periods by the t paired test (p < 0.05.Results The number of diagnoses reduced in all the subgroups and 41.7% of the 24 participants presented no diagnosis after the treatment. A significant decrease in the TMI was observed between AV1 and AV2 (p = 0.000. There was no difference between AV2 and AV3 (p = 0.204 in 13 participants assessed two months after the end of the treatment.Conclusion The multimodal physiotherapeutic approach resulted in positive effects, short and medium-term, on the symptoms and clinical signs, with deletion of the dysfunction or reduction of its severity in treated patients.

    Purpose The purpose of the present study was to perform a pattern analysis in patients with temporomandibular disorder (TMD) resulting from unilateral mastication due to chronic periodontitis. Methods Thirty participants with signs or symptoms of TMD who engaged in unilateral mastication due to periodontitis-related discomfort (test group) were selected. Another 30 subjects exhibiting signs or symptoms of TMD resulting from unilateral mastication not due to chronic periodontitis (control group) were also recruited. An interview-based questionnaire was administered, and an examination of the temporomandibular joint (TMJ) with determination of periodontal status was performed. Results The duration of unilateral mastication was significantly longer in the control group than in the test group. There was a significant negative correlation between the duration of unilateral mastication and the Community Periodontal Index score. Using the Research Diagnostic Criteria for TMD (RDC/TMD) axis I algorithms, all the subjects were assigned to 3 main groups. The test group exhibited significantly a higher diagnostic distribution of group III (arthralgia, osteoarthritis, or osteoarthrosis), and in both the test and control groups, the number of diagnoses was larger for the non-chewing side. The control group showed a significantly higher diagnostic distribution of group I (myofacial pain), and in both the test and control groups, the number of diagnoses was larger for the chewing side. Conclusions The results of the present study indicate that unilateral mastication due to chronic periodontitis could induce not only pain but also structural TMJ changes if adequate treatment is not administered and supported within a short time from the onset of the condition. Therefore, immediate treatment of chronic periodontitis is recommended to prevent not only the primary progress of periodontal disease, but also secondary TMJ-related problems. Furthermore, subjects who have suffered chronic

    The aetiology of temporomandibular joint disorders (TMD) is multifactorial, whereas occlusal disharmony is one of the predisposing factors. Researchers still discuss the relation between occlusion and TMD. The study aims to investigate the relation between static occlusal parameters and TMD clinical symptoms using T-Scan II analysis system. The sample consisted of 44 persons divided into the treatment group of 20 TMD patients and the control group of 24 subjects without TMD. The main task of T-Scan II computerized occlusal analysis system was to record every patient's occlusion and estimate static occlusal parameters: centre of occlusal force, asymmetry index of maximum occlusal force and occlusion time. These results were compared between groups, data related to patients' complaints and clinical symptoms. The analysis was carried out using Mann-Whitney U, Kruskal-Wallis and Chi-square tests. Averages of the centre of occlusal force in TMD subjects were 6.55 ± 0.99 mm, in the control group - 5.88 ± 0.69 mm; the asymmetry index of maximum occlusal force averages: 15.90 ± 2.71 and 12.93 ± 1.88; occlusion time: 0.281 ± 0.036 s and 0.236 ± 0.022 s, respectively. There were no statistically significant differences between two groups but they were found in the centre of occlusal force and the asymmetry index in the two groups (p occlusion parameters. Values of the centre of the occlusal force distance and the asymmetry index of occlusal force in TMD patients with pain in the temporomandibular joint (TMJ) were significantly higher than in the control group.

    The aim of this study was to determine the factors associated with temporomandibular disorders (TMD) in the non-institutionalized and institutionalized elderly population of Feira de Santana, Bahia, Brazil. A cross-sectional study was carried out in 307 subjects over 60 years old of both genders, where 80 are institutionalized and 227 are non-institutionalized. The evaluation of TMD signs and symptoms was performed using the Fonseca Anamnestic Index (IAF) as to sociodemographic, systemic and otological factors. The results were analyzed by correlating the study factors and the prevalence of TMD. A 95% confidence interval (CI) and a 5% significance level were established for all the tests used. The results showed that 50.5% of the subjects presented some degree of TMD. The prevalence of TMD was 49.8% among non-institutionalized elderly individuals and of 52.5% among institutionalized individuals. Variation in the prevalence of TMD, with statistical significance according to gender, age, income, tinnitus, dizziness, and depression was observed. The prevalence of TMD was significant among the elderly population. There was no statistically significant difference between the prevalence of TMD in institutionalized and non-institutionalized individuals. Identifying TMD in the elderly population may be difficult because the symptoms of these disorders are similar to symptoms commonly presented in some systemic disorders associated with aging.

    The aim of this study was to research how stress and anxiety affected the development of temporomandibular disorders (TMD) in 55 high school graduates at two different times: six months before and one the week before their college entrance examinations. The American Academy of Orofacial Pain (AAOP) Questionnaire, Lipp's Stress for Adults Inventory (ISSL) and the Beck Anxiety Inventory (BAI) were used to evaluate TMD, stress and anxiety, respectively. The data were submitted to Pearson's and Spearman's correlation tests. At first the results showed higher positive correlation between anxiety and TMD than between stress and TMD. Out of the total participants, 36% had TMD, and of these, only 12.7% had no psychological disorder. One week before the tests there were high positive correlations between TMD and the psychological factors studied, and 50.9% of the students had TMD, of which only 9% had no psychological disorder The most prevalent signs of TMD symptomatology were joint sounds and headache, followed by neck pain. It was concluded that students preparing to take college entrance examinations are a potential risk group for developing TMD due to psychological factors generating anxiety and stress. Anxiety becomes more significant as the semester progresses, and both anxiety and stress increase as the examination dates approach.

    Full Text Available Purpose. We evaluated the efficacy of arthrocentesis in the treatment of temporomandibular joint (TMJ disorders. Material and Methods. In this prospective clinical case series, 30 consecutive patients with TMJ disorders underwent arthrocentesis using saline and sodium hyaluronate injections. Outcome measures were TMJ pain, maximum mouth opening (MMO, joint noises, and anatomical changes in the TMJ architecture. Patients were evaluated using cone-beam computed tomography (CBCT and magnetic resonance imaging (MRI at the beginning of treatment and 60 days after the last arthrocentesis. Pretreatment and posttreatment clinical parameters were compared using paired and unpaired t-tests, and McNemar’s test was used to evaluate CBCT and MRI changes (. Results. At 1-year follow-up examinations, visual analogue scale scores indicated that pain was reduced significantly and mean postoperative MMO was increased significantly. CBCT findings showed no significant change, and MRI showed only slight reductions in inflammatory signs. Conclusions. Within the limitations of this study, we can conclude that arthrocentesis is a simple, minimally invasive procedure with a relatively low risk of complications and significant clinical benefits in patients with TMJ disorders. This trial is registered with NCT01903512.

    The purpose of this study was to assess in a sample of female community cases the relationship between the increase of percentage of cervical signs and symptoms and the severity of temporomandibular disorders (TMD) and vice-versa. One hundred women (aged 18-26 years) clinically diagnosed with TMD signs and symptoms and cervical spine disorders were randomly selected from a sample of college students. 43% of the volunteers demonstrated the same severity for TMD and cervical spine disorders (CSD). The increase in TMD signs and symptoms was accompanied by increase in CSD severity, except for pain during palpation of posterior temporal muscle, more frequently observed in the severe CSD group. However, increase in pain during cervical extension, sounds during cervical lateral flexion, and tenderness to palpation of upper fibers of trapezius and suboccipital muscles were observed in association with the progression of TMD severity. The increase in cervical symptomatology seems to accompany TMD severity; nonetheless, the inverse was not verified. Such results suggest that cervical spine signs and symptoms could be better recognized as perpetuating rather than predisposing factors for TMD.

    Full Text Available Aim: The aim of the study was to evaluate and compare the analgesic efficacy of placebo and diazepam in patients with temporomandibular disorder. Materials and Methods: Thirty-five patients were recruited with a diagnosis of temporomandibular disorder based on standard clinical diagnostic criteria for temporomandibular disorder. The patients were put in to one of the two groups: placebo or diazepam at random. The average pain intensity was recorded with visual analog scale (VAS at pretreatment, at weekly interval till the completion of a three-week trial and at post-treatment visit on the eighth week from baseline. The secondary outcome measures were changes in masticatory muscle tenderness, viz. massater muscle, lateral pterygoid muscle, medial pterygoid muscle and temporalis muscle and changes in mouth opening. Statistical Analysis: Intra-group comparison for analgesic efficacy and mouth opening was carried out by Wilcoxon′s signed ranked test. Inter-group comparison for analgesic efficacy was also carried out using Mann-Whitney′s test. Results: A statistically significant (P<0.01 decrease in temporomandibular disorder pain in the placebo group (65% and statistically highly significant (P<0.001 decrease in the diazepam group (72% were observed on VAS after three weeks of treatment. The inter-group comparison demonstrated no statistically significant difference between the groups. Conclusion: This study suggests that the placebo can give near similar results as diazepam can. So the role of placebo should also be considered as one of the important management strategies. In the short term, reduction in the masticatory muscle tenderness and significant improvement in the mouth opening in both the groups were observed.

    Dentofacial deformities are dys-morpho-functional disorders involving the temporomandibular joints (TMJ). Many authors have reported a TMJ improvement in dysfunctional subjects with malocclusion after orthodontic or combined orthodontic and surgical treatment particularly for the relief of pain. In particular, few studies have highlighted the demographic and clinical predictors of response to surgical treatment. To date, no genetic factor has yet been identified as a predictor of response to surgical treatment. The aim of this cohort study is therefore to identify single-nucleotide polymorphisms associated with postoperative temporomandibular disorders (TMD) or with TMJ symptoms after orthognathic surgery. Here, we found the AA genotype of SNP rs1643821 (ESR1 gene) as a risk factor for dysfunctional worsening after orthognathic surgery. In addition, we have identified TT genotype of SNP rs858339 (ENPP1 gene) as a protective factor against TMD in a population of patients with dentofacial deformities. Conversely, the heterozygous genotype AT was identified as a risk factor of TMD with respect to the rest of our population. All these elements are particularly important to bring new screening strategies and tailor future treatment. This study allows us to identify sub-populations at high risk of developing postoperative temporomandibular disorders after orthognathic surgery procedures. Many other genes of interest could be potential factors influencing the dysfunctional response to orthognathic surgery, particularly genes of the Opera cohort.

    Whether orthodontic therapy is a risk factor for temporomandibular disorders (TMD) or parafunctional habits such as bruxism is a question that has long been discussed. The issue is highly relevant to public health due to the frequency of these functional disorders in the general population and the sheer number of orthodontic treatments. The aim of this cross-sectional study was to investigate the risk of TMD or bruxism in children and adolescents during orthodontic therapy. The study included 1,011 children and adolescents between the ages of 10 and 18 selected at random from the general public who had been examined for signs of TMD using the Helkimo index and Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Parafunctional activities (bruxism) were surveyed and documented in reference to wear effects on the front teeth using the method developed by Egermark-Eriksson. In addition, probands were asked about their current orthodontic treatments. Nearly 30% (N = 296) of the probands stated that they were undergoing orthodontic therapy. Roughly 1/10 proband presented with a clinical TMD according to the Helkimo index (9.6%; N = 97) or a TMD diagnosis according to the RDC/TMD (10.2%; N = 102). After controlling for the effects of age, gender and school-type using a multinomial logistical regression analysis there was no increased risk of anamnestic or clinical TMD symptoms or diagnoses during orthodontic treatment (odds ratios between 0.63 and 1.18; all p-values > 0.05). At the same time, both wear facets on the front teeth (tooth-related mean value with vs. without appliance: 0.12 vs. 0.16; t test: p = 0.038) and self-reported bruxing be havior (OR = 0.57; p = 0.018) were significantly reduced by orthodontic treatment. Our study revealed no increased risk of TMD in children and adolescents during orthodontic therapy, which seems to reduce parafunctional activities and thus the likelihood of noncarious dental damage.

    Background: The prevalence of temporomandibular disorder (TMD) in children and adolescents is in the range of 6-68% and can be triggered or aggravated by emotional stress. Aim: The study was to investigate the prevalence of TMD in Portuguese children and adolescents and its association with emotional stress. Materials and Methods: The sample comprised 3,260 students aged 5-19 years. The questionnaire was used to assess the presence of TMD, and was applied in a single moment. Results: TMD was observed in 821 (25.2%) students. The most common symptoms of TMD were: if considered tense or nervous (52%), have headaches (36.8%), and habit of clenching or grinding teeth (27.3%). The girls had a 1.36 higher probability of developing TMD than boys (95% CI: 1.14-1.63; p < 0.001); moreover, students from the older age group had a 2.31 higher probability of developing the disorder (95% CI: 1.85-2.89; p < 0.001). Students who considered themselves tense or nervous presented 8.74 higher probability (95% CI: 7.03-10.86; p < 0.001) of developing TMD. Conclusion: This study showed a high prevalence of TMD in children and adolescents in southern Portugal, and revealed a significant association between this dysfunction and the levels of emotional stress. Female students, older students, and those considered tense or nervous have a higher probability of developing TMD. PMID:24741551

    The purpose of this study was to elevate comparison of static MRI and pseudo-dynamic (cine) MRI in temporomandibular joint (TMJ) disorder patients. In this investigation, 33 patients with TMJ disorders were examined using both conventional static MRI and pseudo-dynamic MRI. Multiple spoiled gradient recalled acquisition in the steady state (SPGR) images were obtained when mouth opened and closed. Proton density weighted images were obtained at the closed and open mouth position in static MRI. Two oral and maxillofacial radiologists evaluated location of the articular disk, movement of condyle and bony change respectively and the posterior boundary of articular disk was obtained. No statistically significant difference was found in the observation of articular disk position, mandibular condylar movement and posterior boundary of articular disk using static MRI and pseudo-dynamic MRI (P>0.05). Statistically significant difference was noted in bony changes of condyle using static MRI and pseudo-dynamic MRI (P<0.05). This study showed that pseudo-dynamic MRI didn't make a difference in diagnosing internal derangement of TMJ in comparison with static MRI. But it was considered as an additional method to be supplemented in observing bony change.

    Temporomandibular disorders (TMD) are a significant public health problem, affecting approximately 5-12% of the population. This retrospective cross-sectional study investigated the relationship between 8 AM serum cortisol levels (8ASC) and disc displacement disorders (DDD) of TMD. One hundred and forty patients with DDD were recruited. Among them, 60 patients comprised the case group of disc displacement without reduction with limited opening (DDWORWLO, age 37·7 ± 17·22), and 80 were 'other DDD' for the control group (age 36·4 ± 13·08). The independent variables included domains of demography, history, malocclusion, comorbid symptoms, comorbid TMD and 8ASC. Data were analysed with the chi-square test, logistic regression and receiver operating characteristic (ROC) curve. Results of multiple logistic regression showed that 8ASC was the only factor significantly related to DDWORWLO (P = 0·006). Receiver operating characteristic analysis of DDWORWLO and 8ASC indicated an area under the curve of 0·669, standard error of 0·049 and P value of 0·001. The adequate cut-off point of 8ASC was 12·45 (μg dL(-1) ), with sensitivity of 0·636, and specificity of 0·729. 8 AM serum cortisol level can be used as a clinical clue to differentiate DDWORWLO from other DDD. © 2015 John Wiley & Sons Ltd.

TMD pain was assessed by RDC/TMD examination (Research Diagnostic Criteria for Temporomandibular Disorders (Axis I and II. Five-hundred and fifty-eight subjects (330 girls and 228 boys were examined. Bivariate analyses were performed using the Chi-square test (χ2. The logistic regression models were adjusted estimating the Odds Ratios (OR, their 95% confidence intervals (CI, and significance levels. Only 2.19% of the boys and 8.18% of the girls presented one of the Axis I categories. All variables from axis II were related to TMD diagnosis (p < 0.001. Gender was significantly related to TMD diagnosis (p = 0.0028. The risk of TMD incidence for girls was 3.5 times higher than that for boys (Odds Ratio = 3.52, Confidence Interval 1.31-9.43. The individuals who presented the variable "characteristics of pain intensity" (CPI higher than 0 had 31 times more risk of TMD incidence (Odds Ratio = 31.361, Confidence interval 6.01-163.5. We concluded that psychological variables and female gender are important risk indicators related to TMD incidence, even in adolescents.

    Temporomandibular joint disorders (TMDs) usually present with symptoms and signs such as pain, mandibular movement, dysfunction, or joint sounds. Botulinum toxin type A (BTX-A) is a biologic toxin which inhibits skeletal muscle through hindering the production of acetylcholine in the nerve endings. This toxin is used for the treatment of hyperactivity of lateral pterygoid muscle and TMD symptoms. This comprehensive review aimed to evaluate the effect of BTX-A injections in the lateral pterygoid muscle on treatment of TMDs symptoms. In this study, online databases including Scopus, Medline, Ebsco, Cochrane, EMBASE, and Google scholar were searched for the keywords "pterygoid muscle" and "Onabotulinumtoxin A". Twenty-four articles were eligible to be enrolled in the study. In 4 interventional studies and 20 descriptive studies, BTX-A was used for the treatment of TMDs. The dosage and number of injections were different in each study; however, the injection methods were relatively similar. Regardless of the type, number of injections, and dosage, injection of BTX-A in lateral pterygoid seems effective in reducing the click sound and other TMJ-related muscle disorders such as pain, hyperactivity, and dysfunction.

    The objective of this observational study was to establish the possible presence of confounders on the association between temporomandibular disorders (TMD) and headaches in a patient population from a TMD and Orofacial Pain Clinic. Several subtypes of headaches have been diagnosed: self-reported headache, (probable) migraine, (probable) tension-type headache, and secondary headache attributed to TMD. The presence of TMD was subdivided into 2 subtypes: painful TMD and function-related TMD. The associations between the subtypes of TMD and headaches were evaluated by single regression models. To study the influence of possible confounding factors on this association, the regression models were extended with age, sex, bruxism, stress, depression, and somatic symptoms. Of the included patients (n=203), 67.5% experienced headaches. In the subsample of patients with a painful TMD (n=58), the prevalence of self-reported headaches increased to 82.8%. The associations found between self-reported headache and (1) painful TMD and (2) function-related TMD were confounded by the presence of somatic symptoms. For probable migraine, both somatic symptoms and bruxism confounded the initial association found with painful TMD. The findings of this study imply that there is a central working mechanism overlapping TMD and headache. Health care providers should not regard these disorders separately, but rather look at the bigger picture to appreciate the complex nature of the diagnostic and therapeutic process.

    The aims of this investigation were to report the frequency of temporomandibular disorders (TMD) diagnoses and the prevalence of self-reported awake and sleep bruxism as well as to describe the possible differences between findings of two specialised centres as a basis to suggest recommendations for future improvements in diagnostic homogeneity and accuracy. A standardised Research Diagnostic Criteria for TMD (RDC/TMD) assessment was performed on patients attending both TMD Clinics, viz., at the University of Padova, Italy (n=219; 74% women) and at the University of Tel Aviv, Israel (n=397; 79% women), to assign axis I physical diagnoses and to record data on self-reported awake and sleep bruxism. Significant differences were shown between the two clinic samples as for the frequency of TMD diagnoses (chi-square, Pbruxism items (chi-square, Pbruxism in patients with myofascial pain alone described in the other clinic sample was not replicated, suggesting that the different adoption of clinical and imaging criteria to diagnose TMD may influence also reports on their association with bruxism. From this investigation, it emerged that the features of the study samples as well as the different interpretation of the same diagnostic guidelines may have strong influence on epidemiological reports on bruxism and TMD prevalence and on the association between the two disorders. © 2012 Blackwell Publishing Ltd.

    Approaches providing the positioning of human amniotic membrane (HAM) within the intra-articular space of arthritic TMJs have never been investigated. This contrasts with the increasing amount of evidence suggesting the potential positive effects of HAM on a number of surgical conditions, even included the interpositional arthroplasty for TMJ ankylosis. Thus, the possible usefulness of HAM to restore joint functions in severely damaged TMJs could be hypothesized. Based on these premises, the clinical research question "Is human amniotic membrane positioning effective to reduce symptoms and restore jaw function in patients with severe inflammatory-degenerative disorders of the temporomandibular joint?" has been addressed by performing a systematic review of the literature. Out of potential 11988 and 8883 citations in the PubMed and Scopus databases, respectively, only five were of possible interest for inclusion in the review, but none of them addressed specifically the clinical research question. Thus, the hypothetical background for usefulness was discussed. The benefits of HAM positioning in TMJs with severe inflammatory-degenerative disorders could be related with its anti-inflammatory and anti-microbial and analgesic properties as well as its low immunogenicity. Studies in which HAM is positioned within the joint space of patients with severe TMJ degeneration, either as a disc-replacing film during major surgeries for discectomy and arthroplasty or as an injectable solution that can be needle-inserted after an arthrocentesis procedure, should be designed to test the hypothesis.

    Full Text Available A dogmatic view on occlusion as the main aetiological factor for temporomandibular disorder (TMD has been present in the literature for a long time, but a direct scientific correlation between occlusal disorders and TMD has never been proven. The purpose of this study was to determine the frequency of TMD signs and tissue-specific diagnoses in a population of 164 asymptomatic participants, 70 removable partial denture wearers and 94 complete denture wearers of an average age of 61.3 years, by means of clinical manual functional analysis. TMD was found in 42.1% of the participants. No statistically significant difference in the occurrence of TMD was found between removable partial and complete denture wearers and between genders (P > 0.05. The most frequent tissue-specific diagnoses were osteoarthrosis (11%, total anterior disc displacement (9.1% and partial anterolateral disc displacement (8.5%. The frequency of tissue-specific diagnoses was also not influenced by the type of prosthetic replacements.

    This study investigated the effect of temporomandibular disorders on quality of life (QOL) of patients with dentofacial deformities. A case-control study was performed involving 3 age- and gender-matched groups: 38 preoperative participants, 38 postoperative participants, and 39 control participants. Temporomandibular joints were assessed using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD axis I), and QOL was assessed using the Orthognathic Quality of Life Questionnaire (OQLQ) and the Short-Form Health Survey (SF-36). Significantly lower OQLQ scores were found in postoperative patients with one or more RDC/TMD findings; the domains in which these occurred were mental health, dentofacial esthetics, and awareness of dentofacial esthetics for patients with myofascial pain; social aspects and awareness of dentofacial esthetics for patients with disk displacement with reduction; and all domains for patients with arthritis (all P < .05). Despite the variable effect of orthognathic treatment on TMDs, the presence of TMDs in patients after treatment can have a negative effect on their QOL. Copyright © 2014 Elsevier Inc.

    Bone scan is a very sensitive diagnostic imaging test for detecting bone and joint disorders. So it might be useful in the diagnosis of temporomandibular disorders of the joint origin. Thus, the effectiveness of bone scan for detecting temporomandibular joint(TMJ) diseases and differentiating the TMJ disc displacement from the TMJ arthritis was evaluated. Bone scan was done in 21 patients with TMJ disc displacement (I3 unilaterally affected, 8 bilaterally affected), 26 patients with TMJ arthritis (23 unilateral, 3 bilateral), and 39 volunteers with no signs, symptoms, or history of TMJ disease TMJ simple uptake rate(SUR) and difference of both TMJ SUR were calculated from the 100,000 count lateral image of head and neck region in {sup 99m}Tc MDP bone scan. Transcranial and panorama X-ray examination was also done in all patients. TMJ SUR(%) were 1.67 +-0.606 in TMJs affected with arthritis, 1.350+-0.351 in TMJs affected with disc displacement, and 1.084+-0.172 in TMJs of controls Significant differences were demonstrated among them(p<001). Difference of both TMJ SUR was highest in patients with unilateral TMJ arthritis(0.608+-0.533, p<001), and there is no significant difference between that of controls and that of unilateral TMJ disc displacement patients(0.062+-0.063 vs 0.122+-0.100). TMJ SUR of joint with bone change on X-ray finding was not significantly different from that of joint with normal X-ray finding. Those in patients with unilateral TMJ disc displacement(69.6% and 87% vs 23.1% and 23%). The proportions of patients with increased TMJ SUR and difference of both TMJ SUR(>mean+2SD of controls) in unilateral TMJ arthritis patients were significantly higher than those in patients with unilateral TMJ disc displacement(69.6% and 87% vs 23.1% and 23%). Conclusively, bone scan may help to detect TMJ disease and differentiate TMJ disc displacement from TMJ arthritis.

    Modern health care in the field of Medicine, Dentistry and Nursing is grounded in fundamental philosophy and epistemology of translational science. Recently in the U.S major national initiatives have been implemented in the hope of closing the gaps that sometimes exist between the two fundamental components of translational science, the translational research and translational effectiveness. Subsequent to these initiatives, many improvements have been made; however, important bioethical issues and limitations do still exist that need to be addressed. One such issue is the stakeholder engagement and its assessment and validation. Federal, state and local organizations such as PCORI and AHRQ concur that the key to a better understanding of the relationship between translational research and translational effectiveness is the assessment of the extent to which stakeholders are actively engaged in the translational process of healthcare. The stakeholder engagement analysis identifies who the stakeholders are, maps their contribution and involvement, evaluates their priorities and opinions, and accesses their current knowledge base. This analysis however requires conceptualization and validation from the bioethics standpoint. Here, we examine the bioethical dilemma of stakeholder engagement analysis in the context of the person-environment fit (PE-fit) theoretical model. This model is an approach to quantifying stakeholder engagement analysis for the design of patient-targeted interventions. In our previous studies of Alzheimer patients, we have developed, validated and used a simple instrument based on the PE-fit model that can be adapted and utilized in a much less studied pathology as a clinical model that has a wide range of symptoms and manifestations, the temporomandibular joint disorders (TMD). The temporomandibular joint (TMJ) is the jaw joint endowed with sensory and motor innervations that project from within the central nervous system and its dysfunction can

    Full Text Available Abstract Background Temporomandibular disorder (TMD is a multifactorial syndrome related to a critical period of human life. TMD has been associated with psychological dysfunctions, oxidative state and sexual dimorphism with coincidental occurrence along the pubertal development. In this work we study the association between TMD and genetic polymorphisms of folate metabolism, neurotransmission, oxidative and hormonal metabolism. Folate metabolism, which depends on genes variations and diet, is directly involved in genetic and epigenetic variations that can influence the changes of last growing period of development in human and the appearance of the TMD. Methods A case-control study was designed to evaluate the impact of genetic polymorphisms above described on TMD. A total of 229 individuals (69% women were included at the study; 86 were patients with TMD and 143 were healthy control subjects. Subjects underwent to a clinical examination following the guidelines by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD. Genotyping of 20 Single Nucleotide Polymorphisms (SNPs, divided in two groups, was performed by multiplex minisequencing preceded by multiplex PCR. Other seven genetic polymorphisms different from SNPs (deletions, insertions, tandem repeat, null genotype were achieved by a multiplex-PCR. A chi-square test was performed to determine the differences in genotype and allelic frequencies between TMD patients and healthy subjects. To estimate TMD risk, in those polymorphisms that shown significant differences, odds ratio (OR with a 95% of confidence interval were calculated. Results Six of the polymorphisms showed statistical associations with TMD. Four of them are related to enzymes of folates metabolism: Allele G of Serine Hydoxymethyltransferase 1 (SHMT1 rs1979277 (OR = 3.99; 95%CI 1.72, 9.25; p = 0.002, allele G of SHMT1 rs638416 (OR = 2.80; 95%CI 1.51, 5.21; p = 0.013, allele T of Methylentetrahydrofolate

    Dental researchers are contradictory in their opinion on the role of occlusion in TMD. Occlusal evaluation of both conventional and digital methods in TMD patients will provide the accurate information about the factors accountable for occlusal instability. Identifying the factors responsible will facilitate precise diagnosis and treatment for TMD. The AIM of the study was to determine the dynamic occlusal parameters strongly associated with the etiology of Temporomandibular disorders. Study group consisted of 100 patients; it included 50 patients with normal TMJ(Group I) and remaining 50 patients had a minimum of one positive sign or symptom of Temporomandibular disorder (GroupII). The patient's dynamic occlusal contacts were evaluated by both conventional and digital methods. The Articulating paper was utilized for conventional occlusion analysis. During conventional analysis centric, lateral and protrusive interferences were evaluated along with loss of vertical dimension. Digital occlusal analysis was performed with T-Scan III. Clusion time, disclusion times were recorded for both groups. Chi-square and Student't' statistical analyses were performed to ascertain the association and statistically significant difference between the groups using SPSS19. Group II patients predominantly (66%)had Group-function occlusion compared to Group I subject. Centric slide more than 2 mm found to have strong influence (p value 0.008) on the etiology of TMD. Among the occlusal interferences evaluated balanced side interferences had a strong correlation with TMD with p-value of 0.003. Working side interferences, protrusive interferences had a p-value of 0.157, 0.826 respectively, indicating weak association. T-Scan analysis showed Group I had 0.689, 0.9136, 0.7952, 0.9794 seconds of clusion, left, right, protrusive disclusion time respectively compared to corresponding 1.862, 1.7995, 1.6978, 1.9296 seconds for Group II. Statistically significant difference (p≤0.05) was found

    In this report, we describe the incidental finding of an oropharyngeal mass in a patient who presented with a chief complaint of temporomandibular pain. The patient was initially evaluated by an otorhinolaryngologist for complaints of headaches, earache, and sinus congestion. Due to worsening headaches and trismus, he was further referred for the management of temporomandibular disorder. The clinical evaluation was uneventful except for limited mouth opening (trismus). An advanced radiological evaluation using magnetic resonance imaging revealed a mass in the nasopharyngeal/oropharyngeal region. The mass occupied the masticatory space and extended superioinferiorly from the skull base to the mandible. A diagnostic biopsy of the lesion revealed a long-standing human papilloma virus (HPV-16)-positive squamous cell carcinoma of the oropharynx. This case illustrates the need for the timely radiological evaluation of seemingly innocuous orofacial pain.

Estudios epidemiológicos en relación con su prevalencia indican que más del 50 % de la población ha padecido de signos y síntomas relacionados con esta patología, entre los que se encuentran ruidos, dolor articular y limitación al movimiento. El grupo de estudio estuvo constituido por 40 pacientes con trastornos de la articulación temporomandibular (ATM, de ambos sexos y mayores de 20 años, que acudieron a consulta en la Facultad de Estomatología de La Habana. El diagnóstico se estableció por el interrogatorio y el examen clínico. Para la obtención de los datos se creó un formulario con el objetivo de evaluar la eficacia del uso del miniláser en la terapia de los trastornos de la ATM, evaluar la evolución de intensidad dolorosa presente, antes y después del tratamiento con láser y tratamiento farmacológico, así como determinar el número de aplicaciones necesarias para el alivio total o parcial del dolor y músculo con mayor afectación. La aplicación de la técnica se realizó en 2 grupos; el primero recibió terapia farmacológica activa y el segundo terapia láser. Al culminar el tratamiento se evaluaron los casos y se remitieron a la consulta de ATM para el tratamiento definitivo. Los resultados revelaron que el mayor porcentaje de los pacientes tuvo remisión total del dolor con el tratamiento con láser terapia, en relación con los que se trataron con fármacos, al igual que el índice de dolor presente.Temporomandibular Disorders (TMD are a world health problem.

    Impulse control disorders in Parkinson's disease are a group of impulsive behaviors most often associated with dopaminergic treatment. Presently, there is a lack of high quality evidence available to guide their management. This manuscript reviews current management strategies, before concentrating on the concept of dopamine agonist withdrawal syndrome and its implications for the management of impulse control disorders. Further, we focus on controversies, including the role of more recently available anti-parkinsonian drugs, and potential future approaches involving routes of drug delivery, nonpharmacological treatments (such as cognitive behavioral therapy and deep brain stimulation), and other as yet experimental strategies. © 2015 International Parkinson and Movement Disorder Society.

    Very little is known about the ability of dentists to diagnose and treat temporomandibular disorders (TMDs). The aims of this study were to investigate whether dentists in Central Thailand diagnosed TMD subcategories before initiating treatment for TMDs and to explore the frequency of corresponding treatments. A questionnaire covering TMD management was developed and posted to all Ministry of Public Health dentists (n = 969) in Central Thailand. The data were analysed using descriptive statistics. The respondents (n = 502) comprised 109 (21.7%) male and 393 (78.3%) female dentists between 23 and 59 years of age (mean age = 34.7 years). In the preceding year, 427 (85.1%) reported encountering patients with TMDs, 356 (70.9%) had treated patients who had TMDs and 176 (49.4%) had diagnosed TMD subcategories. Most respondents regularly treated patients by providing patient education and encouraging self-care. The respondents who did not diagnose subcategories primarily treated TMDs with pharmacotherapy and physical therapy; orthopaedic appliances and occlusal therapy were used less often. Respondents who diagnosed TMD subcategories did not often use orthopaedic appliances or occlusal therapy to treat muscle disorders. For the treatment of derangement disorders, respondents used fewer pharmacotherapy, physical therapy and occlusal therapy techniques. For the treatment of osteoarthritis, respondents used less physical therapy and fewer orthopaedic appliances. Most Ministry of Public Health dentists in the Central Thailand region encounter and treat patients with TMDs. Approximately 50% of the respondents diagnosed TMD subcategories before providing treatment for TMDs. © 2017 FDI World Dental Federation.

    AIMS To evaluate the psychometric properties of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) biobehavioral (Axis II) screening instruments. METHODS Participants with Axis I TMD diagnoses (n=626) completed the Axis II instruments (Depression, Nonspecific Physical Symptoms, Graded Chronic Pain) and other instruments assessing psychological distress, pain, and disability at three study sites. Internal consistency, temporal stability, and convergent/discriminant validity of the Axis II measures were assessed. To assess criterion validity of Depression and Nonspecific Physical Symptoms instruments as screeners, 170 participants completed a structured psychiatric diagnostic interview. RESULTS The Axis II instruments showed very good-excellent internal consistency (Cronbach’s alpha = 0.80 – 0.95). Their convergent (correlation range 0.3–0.9) and discriminant (range 0.0–0.6) validity were generally supported, although Nonspecific Physical Symptoms was more strongly associated with depressive than with somatic symptoms. Temporal stability was high for characteristic pain intensity (Lin’s correlation concordance coefficient [CCC] = 0.91), interference (CCC = 0.89), and chronic pain grade (weighted kappa = 0.87), and fair-good for Depression and Nonspecific Physical Symptoms (CCC = 0.63 – 0.78). The Depression instrument normal vs moderate-severe cut-point was good at identifying current-year DSM-IV depression and dysthymia diagnoses (sensitivity 87%, specificity 53%). Nonspecific Physical Symptoms did not have high utility for detecting psychiatric disorders (sensitivity 86%, specificity 31%). CONCLUSION The Axis-II Depression and Graded Chronic Pain instruments have clinically relevant and acceptable psychometric properties for reliability and validity and utility as instruments for identifying TMD patients with high levels of distress, pain, and disability that can interfere with treatment response and course of Axis I disorders

    Temporomandibular disorder (TDM) is defined as a heterogenous group of psychophysiological disorders commonly characterised by orofacial pain, chewing dysfunction or both. Various Epidemiological studies had shown occurrence of TMD in all age groups including children. Also research had shown that non nutritional oral habits to be associated with TMD. Present study aimed to find whether harmful oral habits are associated with sign and symptoms of TMD among adolescents in Greater Noida. Schools in Gautam Buddha district and descriptive study. Cross sectional study was carried out among 240 adolescents (10 - 19 years) studying in schools of Greater Noida. Study population were selected by random sampling to whom screening questionnaires recommended by American Academy of Orofacial Pain (AAOP) were distributed. Patient history and clinical examination was used to determine harmful oral habits. Data analysis was done in SPSS version 21 and Chi-square test was applied. Sixty one participants (25.4%) displayed no sign and symptoms of TMD, 34 (14.2%) responded affirmatively to atleast one item on the questionnaire and 108(46%) gave at least three affirmative responses. Headache, Neckpain and Toothache were most frequent reported sign and symptoms of TMD (46.2%). There was statistically significant association between gender and sign and symptoms of TMD on three items of the questionnaire (p Grinding of teeth (p = 0.01) and sign and symptoms of TMD. A statistically significant association was found between nail biting, lip/ object biting and grinding of teeth with signs and/or symptoms of TMD. Thus there is need for preventive dental treatment and community dental education so that young adults realize importance of early diagnosis and treatment of TMJ disorders.

    The aim of this study was to analyze dentist's clinical decision-making related to treatment need for temporomandibular disorders (TMD) in an adult population. The study population comprised 779 randomly selected 35, 50, 65 and 75 year old individuals living in the county of Västerbotten, Sweden. The participants filled out a questionnaire and were examined clinically according to a structured protocol. The four examiners (two men, two women) were experienced dentists and were calibrated before the start of the study. After examination they individually assessed the need of treatment owing to TMD. In total, 15% of the study population was considered to have a treatment need owing to TMD. The highest estimate was noted for 35 and 50 years old women and the lowest for 65 and 75 years old men. Overall, 21% of the women and 8% of the men were considered to have a treatment need owing to TMD, with statistically significant differences between men and women for the 35 and 50 years old groups. Inter-individual variations in dentists' decisions were observed. In a multivariate analysis, female gender, signs and symptoms of TMD pain, signs and symptoms of TMD dysfunction and smoking were associated with estimated treatment need. The prevalence of estimated treatment need owing to TMD was fairly high, but the dentists' clinical decision-making process showed large inter-individual variability. The observation calls for further research on the factors affecting the decision-making process in care providers.

    To conduct a systematic review to evaluate the evidence of possible benefits of tailored treatments for temporomandibular disorders (TMD) based on randomized controlled trials (RCTs). Reports of RCTs investigating treatments tailored to TMD patients' psychosocial characteristics were systematically searched for through March 2013 in the following databases: Cochrane Central Register of Controlled Trials, PubMed, and Web of Science. The methodological quality of the RCTs was assessed using the Cochrane Collaboration's tool for assessing risk of bias. Seven reports met the inclusion criteria. In all studies a subgroup of TMD patients, mainly identified by multidimensional diagnostic systems such as the Research Diagnostic Criteria for TMD Axis II or Multidimensional Pain Inventory, were offered a treatment intervention hypothesized to be suitable for that particular patient group. The quality of the trials was compromised in all cases. Two studies focused on well-functioning TMD patients. In both studies, self-care gave results equal to or better than usual conservative TMD treatment. The treatments were targeted for patients with compromised psychosocial adaptation in five studies, and typically included a cognitive behavioral treatment component. In all trials the results supported the efficacy of tailored treatment, albeit in one trial only in the short-term. The identified studies offer cautious support to the notion that treatment targeted to different psychosocial subgroups of TMD pain patients may be beneficial.

    Full Text Available OBJECTIVE: Orthodontics as an option for treatment and prevention of Temporomandibular Disorders (TMD is a topic that has generated discussion over time. While an occlusion current defends Orthodontics as an alternative to treatment, another current defends more conservative and reversible treatments. The objective of this study, through a systematic literature review, was to analyze the relationship between Orthodontics and TMD, checking the effects of orthodontic therapy in treatment and prevention of TMD. METHODS: Survey in research bases: MEDLINE, Cochrane, EMBASE, Pubmed, Lilacs and BBO, between the years of 1966 and May 2009, with focus in randomized clinical trials, non-randomized prospective longitudinal studies, systematic reviews and meta-analysis was performed. RESULTS: After application of the inclusion criteria 11 articles were selected, 9 which were non-randomized prospective longitudinal studies, 1 randomized clinical trial and 1 systematic review. CONCLUSIONS: According to the literature, there is a lack of specific studies that evaluated Orthodontics as an option for treatment and prevention of TMD. Thus the data conclude that there is no significant scientific evidences that orthodontic treatment treats or prevents TMD.

    Full Text Available Abstract Introduction This study aimed at identifying the factors that influence the incidence of temporomandibular disorders (TMD-related symptoms (TRS in a Japanese working population. Methods Our study subjects comprised of 1,969 employees from the same Japanese company. The subjects were assessed using a questionnaire that covered both TRS and the work environment. TRS were measured from 4 items on the questionnaire. The work environment factors recorded were the daily mean duration of personal computer use, driving, precise work, commuting, time spent at home before going to bed, sleeping, attending business meetings, and performing physical labor. Statistical analysis was performed using t-tests, Chi-square tests, and logistic regression analyses. A result with P  Results The median total score on the 4 items used to assess TRS was 5 (25% = 4, 75% = 7. Two groups were defined such that the participants scoring ≤7 were assigned to the low-TRS group and those scoring ≥8, to the high-TRS group. The high-TRS group constituted 22.6% of the subjects. Logistic regression analyses indicated that female gender and extended periods of computer use were significant contributors to the manifestation of TRS. Conclusion This questionnaire-based study showed that gender and computer use time was associated with the prevalence of TRS in this working population. Thus, evaluation of ergonomics is suggested for TMD patients.

    To investigate the related risk factors of temporomandibular disorders(TMD), and to provide evidences for clinical prevention. One hundred and nine TMD patients were included in the study as case group, while 109 people with no TMJ symptoms and signs were selected randomly as control group. All subjects fulfilled questionaires. Logistics regression analysis was used to analyze the data with SPSS 22.0 software package. Females patients were more common than males, with 20~29 age group accounting for 44%. The proportions of patients with habits of bruxism or clenching, unilateral mastication and maxillofacial injure history were significantly greater than those of control group (P0.05). TMD has a higher prevalence in female than in male, with a peak incidence in 20-29 age group. Habits of bruxism or clenching, unilateral mastication and maxillofacial injury history may be risk factors of TMD, while life stress, habits of stay-up late, chewing hard food and orthodontic treatments show no significant correlation with TMD.

    The aim of this study was to assess the validity and reliability of the Fonseca Anamnestic Index (IAF), used to assess the severity of temporomandibular disorders, applied to Brazilian women. We used a probabilistic sampling design. The participants were 700 women over 18 years of age, living in the city of Araraquara (SP). The IAF questionnaire was applied by telephone interviews. We conducted Confirmatory Factor Analysis (CFA) using Chi-Square Over Degrees of Freedom (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA) as goodness of fit indices. We calculated the convergent validity, the average variance extracted (AVE) and the composite reliability (CR). Internal consistency was assessed by Cronbach’s alpha coefficient (a).The factorial weights of questions 8 and 10 were below the adequate values. Thus, we refined the original model and these questions were excluded. The resulting factorial model showed appropriate goodness of fit to the sample (c2/df = 3.319, CFI = 0.978, TLI = 0.967, RMSEA = 0.058). The convergent validity (AVE = 0.513, CR = 0.878) and internal consistency (a = 0.745) were adequate. The reduced IAF version showed adequate validity and reliability in a sample of Brazilian women.

    For diagnostic imaging of temporomandibular joint (TMJ) disorders, 1.5 tesla superconducting magnet system was applied in 65 patients with 75 joints. MR imaging was performed with GE-Signa 1.5 tesla MR imaging system with the body coil used as the transmitter and 3 inch surface coil as the receiver. For detecting T{sub 1} weighted images, the following parameters were used; TR: 1000, TE: 25, Excitation: 1. Data matrix: 256 x 128, FOV: 8 cm, Slice thickness: 3 mm. For taking T{sub 2} weighted images, TR: 2200, TE:80 was used. For anatomical interpretation of TMJ, 3-mm thick images with a 1-mm interspace sagittal multiplane with TR: 1000/TE: 25 sequence was useful, and additional coronal images were beneficial for examining condylar morphology as well as mediolateral disk position. T{sub 2} weighted imaging obtained the joint effusion suspected of intra-articular inflammation. These findings suggest that MR imaging is useful in the detection and evaluation of TMJ patho-morphology. (author).

    Full Text Available Dysregulation of Autonomic Nervous System (ANS and central pain pathways in temporomandibular disorders (TMD is a growing evidence. Authors include some forms of TMD among central sensitization syndromes (CSS, a group of pathologies characterized by central morphofunctional alterations. Central Sensitization Inventory (CSI is useful for clinical diagnosis. Clinical examination and CSI cannot identify the central site(s affected in these diseases. Ultralow frequency transcutaneous electrical nerve stimulation (ULFTENS is extensively used in TMD and in dental clinical practice, because of its effects on descending pain modulation pathways. The Diagnostic Criteria for TMD (DC/TMD are the most accurate tool for diagnosis and classification of TMD. However, it includes CSI to investigate central aspects of TMD. Preliminary data on sensory ULFTENS show it is a reliable tool for the study of central and autonomic pathways in TMD. An alternative classification based on the presence of Central Sensitization and on individual response to sensory ULFTENS is proposed. TMD may be classified into 4 groups: (a TMD with Central Sensitization ULFTENS Responders; (b TMD with Central Sensitization ULFTENS Nonresponders; (c TMD without Central Sensitization ULFTENS Responders; (d TMD without Central Sensitization ULFTENS Nonresponders. This pathogenic classification of TMD may help to differentiate therapy and aetiology.

    The temporomandibular joint(TMJ) is really a complex of two synovial space separated by fibrocartilaginous disc. Single inferior joint space arthrography is commonly performed for evaluation of TMJ disorders, which is known to be superior in demonstrating joint dynamics. But it reveals only the inferior surface of the disc. Therefore, dual space arthrography is superior to demonstrate the soft tissue anatomic feature of the joint such as disc position and shape. Authors performed 83 TMJ arthrograms in TMJ problems. Initially, the inferior joint space was done and then the superior space was sequentially contrasted. The follow results were noted: 1. In all cases, dual space arthrography revealed accurate disc shape and positions. 2. Concordant findings between the two techniques: 68 cases (82%). Discordance between the two techniques: 15 cases (18%) 3. Possible causes of discordance between inferior and dual space arthrography. a) Normal varians of anterior recess: 3 cases b) Posterior disc displacement: 4 cases c) Influence of the patient's head position change :4 cases d) False perforation: 2 cases e) Reduction change: 2 cases 4. In 5 cases with anterior displacement, dual space arthrography gave additional findings such as adhesion within the superior space, which could not be evaluated by single inferior space.

    The aim of this qualitative systematic review was to identify the behaviour change techniques most frequently employed in published temporomandibular disorder (TMD) self-management (SM) programmes. The reviewers matched the components of SM programmes into the relevant behaviour change technique domains according to the definitions of the behaviour change taxonomy (version 1). Electronic databases were searched for randomised controlled trials assessing an SM programme for TMD. Manual searches were also conducted for potentially important journals. Eligibility criteria for the review included: the type of study, the participants, the intervention utilised and the comparators/control. Fifteen randomised controlled trials with 554 patients were included in this review. The review concludes a minority of the available behaviour change techniques are currently employed in SM programmes. Other behaviour change techniques should be examined to see whether there is a theoretical underpinning that might support their inclusion in self-management programmes in TMD. Further trials are required to conclude that SM programmes are more effective than no treatment at all and or placebo. With more structured SM programmes, greater therapeutic benefits might be achieved, and certainly if SM programmes published in the literature define their components through use of the behaviour change taxonomy, it would be easier for clinicians to replicate efficacious programmes. © 2016 John Wiley & Sons Ltd.

    BACKGROUND: The association between body postural changes and temporomandibular disorders (TMD) has been widely discussed in the literature, however, there is little evidence to support this association. OBJECTIVES: The aim of the present study was to conduct a systematic review to assess the evidence concerning the association between static body postural misalignment and TMD. METHOD: A search was conducted in the PubMed/Medline, Embase, Lilacs, Scielo, Cochrane, and Scopus databases including studies published in English between 1950 and March 2012. Cross-sectional, cohort, case control, and survey studies that assessed body posture in TMD patients were selected. Two reviewers performed each step independently. A methodological checklist was used to evaluate the quality of the selected articles. RESULTS: Twenty studies were analyzed for their methodological quality. Only one study was classified as a moderate quality study and two were classified as strong quality studies. Among all studies considered, only 12 included craniocervical postural assessment, 2 included assessment of craniocervical and shoulder postures,, and 6 included global assessment of body posture. CONCLUSION: There is strong evidence of craniocervical postural changes in myogenous TMD, moderate evidence of cervical postural misalignment in arthrogenous TMD, and no evidence of absence of craniocervical postural misalignment in mixed TMD patients or of global body postural misalignment in patients with TMD. It is important to note the poor methodological quality of the studies, particularly those regarding global body postural misalignment in TMD patients. PMID:25590441

    The purpose of this study was to investigate the prevalence of temporomandibular disorders (TMD) in denture wearers and the association between prosthetic factors and this condition. There is no consensus about the relationship between prosthetic factors and TMD among denture wearers. The sample was composed of 92 patients wearing both maxillary and mandibular complete dentures. The Research Diagnostic Criteria for TMD (RDC/TMD) were adopted for patient examination. Objective evaluation of denture quality was determined by analysis of retention and stability of mandibular denture, interocclusal distance, articulation and occlusion. Association between denture quality and TMD diagnosis was analysed using chi-square and Fisher's exact tests. 37.4% of the patients presented TMD. Denture quality was not significantly associated with the presence of TMD: mandibular retention (p = 0.466); mandibular stability (p = 0.466); interocclusal distance (p = 0.328); centric relation (p = 0.175); and balanced occlusion (p = 0.56). Within the scope of this case-controlled cross-sectional study, no robust association between prosthetic factors and TMD was found. © 2013 The Gerodontology Society and John Wiley & Sons A/S.

    Oral health-related quality of life (OHRQoL) is considered an important aspect of different oral conditions. It has also gained increased attention in temporomandibular disorders (TMDs) in recent years. The purpose of this study was to systematically review the literature on OHRQoL and TMDs. A systematic search of the dental literature was performed using the Medline and Cochrane Library databases, supplemented by a hand search. Various combinations of search terms related to OHRQoL and TMDs were used. Among numerous titles found in Medline, abstracts and eventually full papers of potential interest were reviewed. Twelve papers fulfilled the inclusion criteria and were included in the review. Most studies used the Oral Health Impact Profile, an instrument with good psychometric properties, for evaluation. All articles described a substantial impact on OHRQoL in TMD patients. Only a small proportion of all patients, a few percent, reported no impact at all. The difference between men and women was small and not significant. The impact appeared to be more pronounced in patients with more signs and symptoms. The perceived impact of pain on OHRQoL seems to be substantial. Two studies found that the impact increased with age among TMD patients. The reviewed studies convincingly demonstrated that OHRQoL was negatively affected among TMD patients.

    Epidemiology reports state temporomandibular joint disorders (TMD) affect up to 25% of the population, yet their etiology and progression are poorly understood. As a result, treatment options are limited and fail to meet the long-term demands of the relatively young patient population. TMD are a class of degenerative musculoskeletal conditions associated with morphological and functional deformities. In up to 70% of cases, TMD are accompanied by malpositioning of the TMJ disc, termed “internal derangement.” Though onset is not well characterized, correlations between internal derangement and osteoarthritic change have been identified. Due to the complex and unique nature of each TMD case, diagnosis requires patient-specific analysis accompanied by various diagnostic modalities. Likewise, treatment requires customized plans to address the specific characteristics of each patient’s disease. In the mechanically demanding and biochemically active environment of the TMJ, therapeutic approaches capable of restoring j
