    Bruxism is the non-functional clenching or grinding of the teeth that may occur during sleep or, less commonly in the daytime in 5-20% of adults and about 30% of 56 year old children. Although research on bruxism is extensive, its etiology remains debatable. There is some literature to suggest that bruxism is correlated with temporomandibular disorders (TMDs) and malocclusion. The aim of this article is to present the course of this condition in a case of bruxism coupled with TM...

    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. PMID:27041534

    Temporomandibular disorders (TMD) is a joint term that encompasses a number of clinical symptoms that involve the teeth, masticatory musculature and temporomandibular joints (TMJ). They are a frequent cause of orofacial medical conditions. The aetiology of disorders is complex and individual etiologic factors are not sufficiently defined. Bruxism, in its centric or eccentric form, is becoming a frequent problem for dentists. The purpose of this study is to show factors of the condyle leading in patients with bruxism by optoelectronic pantography, and to establish the possibility of using optoelectronic pantography in the diagnostic procedure of TMD. Patients were selected (N = 42), with incomplete sets of teeth, without prosthodontic appliances and with traces and symptoms of TMD. After completing the history questionnaire a clinical check up and plaster cast analysis patients with bruxism were selected (N = 22) and without bruxism (N = 20). During the study optoelectronic String-condylocomp LR3, Dentron, D-Höchberg (software JAWS 30) was used. This study showed the possibility of applying optoelectronic pantography in TMD diagnostics and compares history, clinical and condylographic parameters in TMD patients with and without bruxism. Optoelectronic pantography enables us, by using relatively easy methods, to determine a more accurate diagnosis, highly important when choosing therapeutic methods and control of the aforementioned disorders.

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

    Correct functioning of the entire stomatognathic system is achieved by a compatible relationship of all its parts. Four determinants, by their mutual harmonious activity, dictate the function of the entire system: the teeth, periodontium with supporting structure, muscles, temporomandibular joint (TMJ) and CNS. In such a complex system a disorder of any integrative part causes disturbances also in other parts of the system. Changed functions can arise through organic disorder, and also iatrogenically by inadequate conservative, prosthetic, surgical or orthodontic therapy. For this reason it is often difficult to recognise the primary cause. The first responses of the system to the disorder are adaptive mechanisms which occur within one or more integrative parts, and depending on their intensity and duration symptoms grow more prominent. Tissue response can be ortho- or parafunctional. Attempts are made to exclude psychoemotional influences and the obstacle eliminated by either abrasion, clenching or grinding of the teeth. If the obstacle is not eliminated by abrasion, the cause of such functional disorder becomes the trigger for parafunctional activity. From a review of the relevant literature it can be concluded that parafunctional activity is caused by changed occlusion, with determined psychological habits of the patient and specific tissue response of the stomatognathic system. Therefore, therapy of these disorders is made more difficult and includes a multidisciplinary approach. PMID:17912197

    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.

    Sleep bruxism (SB), primarily involving rhythmic grinding of the teeth during sleep, has been advanced as a causal or maintenance factor for a variety of oro-facial problems, including temporomandibular disorders (TMD). As laboratory polysomnographic (PSG) assessment is extremely expensive and time-consuming, most research testing this belief has relied on patient self-report of SB. The current case-control study examined the accuracy of those self-reports relative to laboratory-based PSG assessment of SB in a large sample of women suffering from chronic myofascial TMD (n = 124) and a demographically matched control group without TMD (n = 46). A clinical research coordinator administered a structured questionnaire to assess self-reported SB. Participants then spent two consecutive nights in a sleep laboratory. Audiovisual and electromyographic data from the second night were scored to assess whether participants met criteria for the presence of 2 or more (2+) rhythmic masticatory muscle activity episodes accompanied by grinding sounds, moderate SB, or severe SB, using previously validated research scoring standards. Contingency tables were constructed to assess positive and negative predictive values, sensitivity and specificity, and 95% confidence intervals surrounding the point estimates. Results showed that self-report significantly predicted 2+ grinding sounds during sleep for TMD cases. However, self-reported SB failed to significantly predict the presence or absence of either moderate or severe SB as assessed by PSG, for both cases and controls. These data show that self-report of tooth grinding awareness is highly unlikely to be a valid indicator of true SB. Studies relying on self-report to assess SB must be viewed with extreme caution.

    Full Text Available Abstract Background The NTI-tss device is an anterior bite stop, which, according to the manufacturer, is indicated for the prevention and treatment of bruxism, temporomandibular disorders (TMDs, tension-type headaches, and migraine. The aim of this systematic review was to appraise the currently available evidence regarding the efficacy and safety of the NTI-tss splint. Methods We performed a systematic search in nine electronic databases and in NTI-tss-associated websites (last update: December 31, 2007. The reference lists of all relevant articles were perused. Five levels of scientific quality were distinguished. Reporting quality of articles about randomized controlled trials (RCTs was evaluated using the Jadad score. To identify adverse events, we searched in the identified publications and in the MAUDE database. Results Nine of 68 relevant publications reported about the results of five different RCTs. Two RCTs concentrated on electromyographic (EMG investigations in patients with TMDs and concomitant bruxism (Baad-Hansen et al 2007, Jadad score: 4 or with bruxism alone (Kavaklı 2006, Jadad score: 2; in both studies, compared to an occlusal stabilization splint the NTI-tss device showed significant reduction of EMG activity. Two RCTs focused exclusively on TMD patients; in one trial (Magnusson et al 2004, Jadad score: 3, a stabilization appliance led to greater improvement than an NTI-tss device, while in the other study (Jokstad et al 2005, Jadad score: 5 no difference was found. In one RCT (Shankland 2002, Jadad score: 1, patients with tension-type headache or migraine responded more favorably to the NTI-tss splint than to a bleaching tray. NTI-tss-induced complications related predominantly to single teeth or to the occlusion. Conclusion Evidence from RCTs suggests that the NTI-tss device may be successfully used for the management of bruxism and TMDs. However, to avoid potential unwanted effects, it should be chosen only if certain a

    Full Text Available OBJETIVO: verificar a ocorrência de bruxismo em sujeitos adultos do sexo feminino com queixa de disfunção temporomandibular e sua relação com o grau de sintomatologia da disfunção. MÉTODOS: participaram deste estudo 28 mulheres na faixa etária de 19 a 56 anos, que apresentavam sintomas de disfunção temporomandibular e que não haviam realizado tratamento anterior. Todas responderam o questionário de Índice Anamnésico proposto por Fonseca et al (1994, o qual possibilita a classificação do grau de sintomatologia de disfunção temporomandibular e verificação da queixa do hábito parafuncional bruxismo; e realizaram uma avaliação odontológica, constituída de exame da musculatura mastigatória, por meio de palpação digital intra e extra-oral, inspeção das articulações temporomandibulares e exame dental. Os resultados foram analisados descritivamente e, para verificar a relação entre o grau de severidade da disfunção temporomandibular com a ocorrência de bruxismo, foram realizados o Teste de Independência do Qui-quadrado e o Teste Exato de Fisher, ambos ao nível de significância de 5%. RESULTADOS: verificou-se que o bruxismo esteve presente em 50% dos casos de disfunção temporomandibular. Não houve relação entre o bruxismo e o grau de sintomatologia de disfunção temporomandibular, estabelecido pelo Índice Anamnésico. CONCLUSÃO: os resultados deste estudo sugerem que sujeitos com sintomas de disfunção temporomandibular devem ser questionados e avaliados quanto à presença de bruxismo, independentemente do grau de sintomatologia da disfunção. Assim como deve ser realizado diagnóstico e tratamento do bruxismo em sujeitos assintomáticos de disfunção temporomandibular como forma de prevenir o desenvolvimento de lesões nas articulações temporomandibulares e demais estruturas do sistema estomatognático.PURPOSE: to check the occurrence of bruxism in female gender adult subject, with temporomandibular

    The aim of this study was to evaluate the presence of degenerative bone changes of the temporomandibular joint (TMJ) in individuals suffering from sleep bruxism (SB), associating these characteristics with the quality of sleep. For this, we followed the International Classification of Sleep Disorders for the diagnosis of SB, in addition to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) for the classification of TMD and cone beam computed tomography. It was found that 97.7% of the individuals with bruxism had at least 1 RDC/TMD group III diagnosis, 75.6% of the subjects considered their sleep quality as poor, and the largest group (23%) had centric bruxism. There was no significant association between the pattern of sleep quality (P = 0.36), the type of SB (P = 0.277), and the presence of degenerative changes of the TMJ. Regardless of the quality of sleep and the type of bruxism presented, the prevalence of degenerative bone disorders was high (67%) among women with a mean age of 46 years and a clinical diagnosis of SB.

    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. PMID:27475510

Currently no method can permanently eliminate bruxism, but there are several ways to help patients with symptoms caused by parafunctions. Two categories of bruxism are bruxism withous symptoms and bruxism with symptoms that lead to temporomandibular disorders. To make the patient aware of the destructive parafunctional activities, self-monitoring, biofeedback, medications, occlusal adjustment and fabricating a splint can reduce the unfavorable consequences of bruxism.

    Temporomandibular disorders (TMD) have been discussed for more than 70 years without reaching consensus on causes, etiological factors, pathophysiology, or rationale management. Indeed, TMD pain remains an enigma and a diagnostic and management challenge for many clinicians. Perhaps the many and often conflicting views on TMD pain by different health care providers are routed in professional traditions, personal beliefs, experience, and clinical training. This review aims to provide an updated and critical discussion on what is known and supported by scientific evidence about myofascial TMD pain and which gaps there still may be in our understanding of this condition. It has not been the intention to make a systematic review on all aspects of TMD but rather to point out some of the more recent (and important) pieces of information that may help us to better appreciate TMD pain as a complex and multifaceted pain disorder manifested in the craniofacial system.

    This cross-sectional study was designed to evaluate the effect of sleep bruxism, awake bruxism and parafunctional habits, both separately and cumulatively, on the likelihood of adolescents to present painful TMD. The study was conducted on a sample of 1,094 adolescents (aged 12-14). The presence of painful TMD was assessed using the Research Diagnostic Criteria for Temporomandibular Disorders, Axis I. Data on sleep bruxism, awake bruxism and parafunctional habits (nail/pen/pencil/lip/cheek biting, resting one's head on one's hand, and gum chewing) were researched by self-report. After adjusting for potential demographic confounders using logistic regression, each of the predictor variables (sleep bruxism, awake bruxism and parafunctional habits) was significantly associated with painful TMD. In addition, the odds for painful TMD were higher in the concomitant presence of two (OR=4.6, [95%CI=2.06, 10.37]) or three predictor (OR=13.7, [95%CI=5.72, 32.96]) variables. These findings indicate that the presence of concomitant muscle activities during sleep and awake bruxism and parafunctional habits increases the likelihood almost linearly of adolescents to present painful TMD.

    Full Text Available Temporomandibular Disorders (TMD is a disorder that is still controversial in terms of correlation between clinical signs & symptoms and age. Most studies were carried out on adult populations with little attention given to the elderly. The purpose of this study is to elucidate the frequency of TMD in elderly population and risk factors pertinent to it. This is a cross sectional study which included patients aged 60-91 of Geriatric Department of National Hospital Cipto Mangunkusumo, Jakarta, Indonesia. The temporomandibular joint (TMJ was examined for clinical signs & symptoms. Data was analyzed using non parametric Chi Square test. Although there is no significant p value obtained, there is a clear tendency that occurence of TMD diminishes with age, more male elderly experience TMD and elderly experiencing up to 13 tooth loss might have higher risk for TMD.

We conclude that the CMT2 disease did not negatively have influence either on oral health status in the presence and severity of TMD and bruxism or on masticatory performance.

  1. CRITICAL APPRAISAL. Sleep Bruxism and Sleep-Disordered Breathing.

    Science.gov (United States)

    Bender, Steven D

    2016-01-01

    Sleep bruxism (SB) is a repetitive jaw muscle activity with clenching or grinding of the teeth during sleep. SB is characterized by what is known as rhythmic masticatory muscle activity (RMMA). RMMA is the laboratory polysomnographic finding that differentiates SB from other oromandibular movements seen during sleep. Most often RMMA episodes are associated with sleep arousal. Some patients will report similar complaints related to both SB and sleep disordered breathing (SDB). There are some reports that would suggest that SB is a result of SDB. It has has been postulated that SB is a compensatory mechanism to re establish muscle tone of the upper airway. While these disorders do in fact often present concomitantly, the relationship between the two is yet to be fully elucidated. This Critical Appraisal reviews 3 recent publications with the intent to better define what relationships may exists between SDB and SB. While the current evidence appears to support the notion that these are often concomitant disorders, it also makes clear that evidence to support the hypothesis that SDB is causative for SB is currently lacking.

  3. Morphological causes of temporomandibular joint disorder

    International Nuclear Information System (INIS)

    I investigated the contribution of temporomandibular joint (TMJ) morphology to the development of temporomandibular joint disorder (TMD) in a retrospective study of the MR images of TMD patients and individuals free of clinical TMD symptoms. I examined retrospectively the axial MR images of 397 patients with clinical diagnosis of TMD, using 550 individuals without clinical symptoms as controls. The distance between the bilateral mandibular heads, and the horizontal angulation of the mandibular heads were measured for each subject. The average horizontal angulation of the mandibular heads in the TMD group was 20.1deg in males and 18.4deg in females, while the average in the controls was 18.2deg and 19.3deg, respectively. The average distance between the bilateral mandibular heads was 102.8 mm in males and 97.4 mm in females for the TMD group, compared with 106.6 mm and 101.8 mm for the controls, respectively. There was no statistical significance between the horizontal angulation and the distance between the bilateral heads at any age. However, there was a statistical difference of 100 mm in males and 95 mm in females for the distance between the bilateral heads of the TMD group and the controls. These results indicate that this factor may be useful in discriminating between normal individuals and those with TMD, and further suggest that a narrow distance between the bilateral heads rather than horizontal angulation may contribute to the etiology of temporomandibular joint disorder.

    Background and aim This review aims at presenting a current view on the most frequent factors involved in the mechanisms causing temporomandibular disorders (TMD). Method 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. Results 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. Conclusions 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.

  9. Considerations on nuclear techniques in temporomandibular disorders

    International Nuclear Information System (INIS)

    Full text: During the last two decades the advances in imaging diagnostic of the temporomandibular joint (TMJ) have greatly contributed to the assessment of the TMJ disorders including disc displacement, degenerative joint disease (arthrosis) and inflammatory process (arthritis). Arthrography, panoramic and transcranial radiographs are techniques routinely used to evaluate alterations of the TMJ. Linear tomography, computed tomography and magnetic resonance are also widely applied and are methods that supply information with more resolution on the morphologic changes of the T MJ. Scintigraphy has been employed to diagnose a variety of lesions about head and neck, but in the diagnosis of TMJ diseases this technique has been not routinely applied as compared with conventional radiographic techniques. However it may be valuable to assess inflammatory TMJ disorders. The aim of this study is to review the imaging techniques for evaluation of the TMJ disorders and to discuss the potential usefulness of technetium-99m labeled leukocyte scintigraphy in the diagnosis of TMJ arthritis.

    This study was conducted to verify the results of a preceding retrospective pilot study by means of a prospective controlled investigation including a larger sample size. Therefore, the aim of this clinical investigation was to analyze the relationship between sleep bruxism and several functional and occlusal parameters. The null hypothesis of this study was that there would be no differences among sleep bruxism subjects and non-sleep bruxism controls regarding several functional and occlusal parameters. Fifty-eight sleep bruxism subjects and 31 controls participated in this study. The diagnosis sleep bruxism was based on clinical criteria of the American Academy of Sleep Medicine. Sixteen functional and occlusal parameters were recorded clinically or from dental study casts. Similar to the recently published retrospective pilot study, with a mean slide of 0.77 mm (s.d., 0.69 mm) in the sleep bruxism group and a mean slide of 0.4 mm (s.d., 0.57 mm) in the control group, the evaluation of the mean comparison between the two groups demonstrated a larger slide from centric occlusion to maximum intercuspation in sleep bruxism subjects (Mann-Whitney U-test; P=0.008). However, following Bonferroni adjustment, none of the 16 occlusal and functional variables differed significantly between the sleep bruxism subjects and the non-sleep bruxism controls. The present study shows that the occlusal and functional parameters evaluated do not differ between sleep bruxism subjects and non-sleep bruxism subjects. However, as the literature reveals a possible association between bruxism and certain subgroups of temporomandibular disorders, it appears advisable to incorporate the individual adaptive capacity of the stomatognathic system into future investigations.

    Full Text Available Background and Aim: Bruxism has been defined as a diurnal or nocturnal parafunctional habit. Etiology of bruxism has remained controversial and some investigators believe that psychological factors may play a major role in promoting and perpetuating this habit. The aim of this case-control study was to assess the existence of an association between bruxism and psychosocial disorders in adolescents., Participants were chosen among 114, 12-14 year old students (girls. They were divided into two groups, bruxers and nonbruxers, on the basis of both validated clinical criteria and interview with each patient. A few participants were excluded on the basis of presence of systemic disorders, TMJ disorders, other oral habits, primary teeth, defective restorations and premature contacts. Following matching of two groups in regard to parent′s age and education, mother′s marital status, child support status, mother′s employment status, and socio-economical status, 25 cases and 25 controls were enlisted. A self report validated questionnaire (YSR, 11-18 yr was then filled out by both groups for the evaluation of 12 psychosocial symptoms. Results: Remarkable differences in certain psychosocial aspects were found between the two groups. Prevalence of psychosocial disorders including Thought Disorders (P < 0.005, Conduct Disorders (P < 0.05, Antisocial Disorders (P < 0.06 as identified by YSR was significantly higher in bruxers. Significant differences between the two groups also emerged in total YSR scores (P < 0.005. The results of Odds Ratio revealed that a bruxer adolescent has 16 times greater probability for psychosocial disorders than a non-bruxer one. Fischer exact test and T-test were used and Odds Ratio and Confidence Interval was estimated. Conclusion: Support to the existence of an association between bruxism and psychosocial disorders has been provided.

    Psychological stress can induce altered eating patterns, and studies have indicated that there is a correlation between temporomandibular disorder (TMD) and psychological stress. This study investigated the relationship between TMD and body mass index (BMI) in a large representative sample of the South Korean population using data from the Korea National Health and Nutrition Examination Survey (KNHANES). Men and women with TMD showed decreased prevalence of abdominal obesity. Women with TMD had lower age, lower BMI, lower metabolic syndromic waist circumference, lower prevalence of metabolic syndrome, and lower prevalence of diabetes compared with the group without TMD. However, males with TMD didn't show any statistically significant difference between BMI, and metabolic syndromic waist circumference compared with the group without TMD, although there were similar tendencies in the female subject groups. Overall, TMD was associated with decreased BMI and abdominal obesity in women. PMID:27349686

    Francisco Guedes Pereira de Alencar Junior

    2009-01-01

    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).

    Full Text Available Introduction: Bruxism is an oral pnenomenon described as a parafunctional activity involving nocturnal and/or diurnal tooth clenching and/or grinding which may cause teeth wearing, fatigue, pain in the muscles and temporomandibular joints and limitations in mandibular movements. Objective: To classify bruxers in four different subgroups. Material and methods: Evaluation of 162 individuals presenting temporomandibular disorders (TMDs referred consecutively over a period of six years. Chief complaint, history of signs/symptoms and clinical examination were used to gather data. Individuals were classified as TMDs if they were seeking active treatment for the following complaints: pain in the masticatory muscles and/or temporomandibular joints (TMJs, difficulties to perform normal jaw movements, tenderness to palpation of muscle and joints, joint noises and. Patients were classified as mild, moderate, severe and extreme bruxers if they presented 3 to 5, 6 to 10, 11 to 15 or 16 to 25 signs and symptoms of bruxing behavior, respectively. Data was submitted to Chi-square for independence and Fisher’s exact test (p < 0.05. Results: Frequencies of 16.1%, 29.6%, 31.5% and 22.8% of mild, moderate, severe and extreme bruxing behavior were found in this study. Moderate and severe bruxing behavior occurred more frequently than mild and extreme bruxing behavior (p < 0.0001. Conclusion: The four groups of bruxers occurred more or less frequently in this study and mild and extreme bruxing behavior demonstrated the lowest frequencies of such behavior.

    Full Text Available INTRODUCTION: Temporomandibular disorders (TMD and eating disorders (ED affect function and parafunction of the oral cavity and have high rates of medical and psychological comorbidity. However, little is known about the possible associations between them, and few studies have investigated the existence of such associations. METHODS: A search was conducted on the SciELO, LILACS, and PubMed/MEDLINE databases to find relevant articles written in English and Portuguese. Only studies involving human beings were included, and there was no limit for year of publication. RESULTS AND CONCLUSIONS: There is evidence of the correlation between TMD and ED, but their comorbidity must be better understood. The presence of depressive symptoms is an aggravating factor that must also be taken into account during the diagnosis and treatment of those patients.

    Full Text Available Introduction: The influence of occlusal condition on the onset of temporomandibular disorder (TMD has been strongly debated for many years and is still the source of controversy. Until 1980s, the occlusal factors such as the presence of uncured malocclusions, discrepancies between intercuspal position (ICP and retruded contact position (RCP greater than two millimeters, occlusal abnormality, particularly mediotrusion and retrusion, and loss of posterior teeth were considered the primary causes of TMD. Objective: The objective of our study was to find correlation of occlusion disharmonies (difference between ICP and RCP and present sings and symptoms of TMD. Method: The study involved 60 subjects between 18 and 26 years of age who were divided in two groups. The study group consisted of 30 subjects between 18 and 26 years of age with sings and symptoms of temporomandibular disorders (TMD. TMD was confirmed according to Helkimo index. An average value of Helkimo index in this group was 1. The control group included 30 subjects between 20 and 25 years of age without TMD sings and symptoms. An average value of Helkimo index in this group was 0. The function analysis of cinematic centers position in RCP and ICP was performed in each subject using the computer pantograph Arcus-Digma (KaVo EWL GmbH, Leutkirch, Germany. Results: The results of our study showed that the translation tracing of cinematic points from RCP to ICP was significantly different in TMD subjects and asymptomatic group (p>0.16. In addition, the study revealed that 53.4 % of subjects with sings and symptoms of temporomandibular disorders had marked translation in the lower temporomandibular joint (0.61-1.2 mm what directed to intracapsular disorders. Conclusion: The results of our study suggested significant difference of RCP and ICP between subjects with sings and symptoms of the temporomandibular disorders and subjects without sings and symptoms.

    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. PMID:25587737

    Full Text Available Abstract Background The temporomandibular joint is a unique bi-condylar joint involved in mastication and speech. Temporomandibular joint disorders (TMD have a range of symptoms, including aural symptoms, and are present in approximately 75% of normal populations. The present study examined the relationship between signs and symptoms of TMD and mouth opening, gender, joint and aural symptoms, and hearing loss. Methods The study involved 464 healthy Greek university students (156 men and 308 women with a mean age of 19.6 years. Age, gender and maximum mouth opening was recorded. Mouth opening was measured using Vernier calipers. An anamnestic questionnaire was used to stratify the subjects into four groups based on TMD severity. Aural symptoms and an audiogram were recorded for each subject too. Data were analyzed using multifactor ANOVA, chi-square, t-test, Mann-Whitney and Kruskal-Wallis tests. Results The overall incidence of TMD signs and symptoms was 73.3%. The incidence and severity was greater in females than males (p-value 0.0001 Conclusions TMD signs and symptoms were more common and severe in females than males. TMD severity is correlated with the degree of mouth opening and the number of aural symptoms. The absence or presence of mild TMD are associated with normal audiograms while moderate and severe TMD are related to hearing loss in median and low tones respectively. Bruxism, joint ankylosis, joint pain and ear itching were more common in TMD than non-TMD patients.

    2010-03-01

    While considered for years to play the primary role in the etiology of temporo-mandibular joint disturbances (TMD), occlusal discrepancies are now considered to be just one causative factor among many. Recent studies, literature reviews or meta-analyses, and longitudinal studies with follow-up of children treated for many years all conclude that there is no risk of orthodontic treatment giving rise to episodes of temporo-mandibular disorders. The signs of TMD appearing during the course of orthodontic treatment should be considered in the context of the epidemiology of the disorder, which is characterized by a strong increase in its occurrence during adolescence. In conclusion, it should be stated that if orthodontic treatment can no longer be considered as one of the etiopathogenic factors in the TMD complex, there are no scientific arguments to justify the converse, that there are indications for orthodontic treatment whose sole goal would be the treatment 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.

    Full Text Available The aim of this study is to determine the diagnostic value of pressure algometry in temporomandibular disorders. 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.

    The purpose of this study was to investigate for difference in the prevalence of mood disorders between patients with different painful temporomandibular disorders (TMD). After a sample size necessary for the study was calculated, 60 patients with a painful TMD were selected and divided into the following groups: myofascial pain (n=20), temporomandibular joint (TMJ) pain (n=18), combined myofascial and TMJ pain (n=22). Two distinct comparison groups were selected: subjects with a nonpainful TMD (n=25) and TMD-free subjects (n=29). All participants filled out a self-report validated instrument (MOODS-SR) to evaluate psychopathological symptoms related to mood disturbances. A one-way analysis of variance (ANOVA) with Bonferroni's post hoc test for multiple comparisons was performed to investigate for significant differences among the groups. The three groups of patients with painful TMD scored significantly higher than comparison groups in all MOODS-SR domains investigating depression, but no difference was shown between subjects with myofascial pain and those with TMJ pain. No significant differences among the groups emerged for the presence of manic symptoms, indicating that depressive disorders associated with TMD are not an expression of a more complex manic depressive illness. The study concluded that the presence of depressive symptoms in TMD patients seems to be related to the presence of a painful condition and seems to be unrelated to the location of pain. Furthermore, depressive disturbances in painful TMD patients affect the whole spectrum of depressive psychopathology. PMID:15293779

Sixty individuals were evaluated: 30 patients diagnosed with relapsing-remitting MS and 30 control individuals matched for gender and age range with no neurologic pathology. In order to investigate the TMD symptoms, the questionnaires of the EACD (European Academy of Craniomandibular Disorders and the RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders, both validated for TMD research, were administered. To assess the extent of disability produced by MS, the Expanded Disability Status Scale (EDSS was used. The prevalence of TMD symptoms in patients with MS was 56.7% versus 16.7% for the control group, with a statistically significant difference between the groups (p=0.0016. No correlation was found between the severity of MS and the prevalence of TMD symptoms (Fisher's test, p=1.0.

  17. Magnetic resonance imaging-based temporomandibular joint space evaluation in temporomandibular disorders

    International Nuclear Information System (INIS)

    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

    We investigated the temporal association between temporomandibular disorders (TMD)-related symptoms and headache during TMD treatment for patients who fulfilled the diagnostic criteria for headache attributed to TMD (HATMD) specified in the Diagnostic criteria for TMD (DC/TMD) and International classification of headache disorders (ICHD)-3 beta. The study enrolled 34 patients with HATMD induced by masticatory myofascial pain but not by temporomandibular arthralgia. Facial pain intensity, the pressure pain threshold of pericranial muscles, and maximum unassisted opening of the jaw were assessed at an initial examination and before and after physical therapy. The intensity and frequency of headache episodes and tooth contact ratio were also recorded before and after the intervention. Headache intensity and frequency significantly decreased, and these reductions were temporally related to improvements in facial pain intensity, maximum unassisted opening, and pressure pain threshold during TMD treatment. Linear regression analysis showed significant correlations between facial pain intensity and headache intensity and between tooth contact ratio and pressure pain threshold. Among patients who fulfilled the DC/TMD and ICHD-3 beta diagnostic criteria for HATMD, headache improved during TMD treatment, and the improvement was temporally related to amelioration of TMD symptoms. These findings suggest that sensitization in the central and peripheral nervous systems is responsible for HATMD. (J Oral Sci 58, 195-204, 2016). PMID:27349540

  3. Can pterygoid plate asymmetry be linked to temporomandibular joint disorders ?

    International Nuclear Information System (INIS)

    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

    Our aim was to evaluate the occlusal force and therapeutic efficacy of the masseteric muscles after intramuscular injection of botulinum toxin A (BTX-A) for the treatment of patients with concurrent temporomandibular disorders (TMD) and bruxism. Thirty patients with TMD associated with bruxism were randomised into three groups (n=10 in each group), and treated by bilateral intramuscular injection of BTX-A into the masseter, placebo, or control. We used an occlusal force analysis system to collect several measures of occlusal force such as duration of biting and closing, the maximum occlusal force, and the distribution of occlusal force. The occlusal force in the intercuspid position was reduced in all three groups. There was a significant difference between the BTX-A and placebo groups (F(df=1)=8.08, p=0.01) but not between the control group and the other two(F(df=1)=4.34, p=0.047). The duration of occlusion was significantly increased in the BTX-A group after 3 months' treatment (t=4.07, p=0.003). The asymmetrical distribution of occlusal force was reduced in all three groups, but not significantly so (Levene's test F(df=2)=0.25, p=0.78,ANOVA F(df=2)=0.50, p=0.61). Treatment of TMD with BTX-A is effective in reducing the occlusal force, but psychological intervention plays an important part in treatment. PMID:27138229

  7. Peran 'Oral Splint' pada Bruxisme

    2013-07-01

    Full Text Available Oral splints have been frequently used in the treatment of bruxism to protect teeth and periodontium from damage, but the mechanism of action and efficacy of oral splints remain controversial. It has been suggested that they can be used to treat bruxism, based on the assumption that the device can eliminate or remove occlusal interference. Currently there are no reliable data to support the assumption of occlusion as an etiologic factor for bruxism, because several other factors have a role in bruxism, such as psychiatric, neurological and systemic disorders. In this paper, the mechanism of action and efficacy of oral splints in bruxism are discussed. Conclusions: although oral splint may be beneficial in protecting the dentition, the efficacy of this device in reducing bruxism is still not confirmed. There are several aspects that would support the broad usage of oral splints in the treatment of bruxism, but there are also limitations associated with each of these aspects. In conclusion, oral splints can be considered as useful adjuncts in the management of sleep bruxism but not as a definitive treatment.DOI: 10.14693/jdi.v15i1.82

    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)

  10. Association between magnetic resonance imaging, temporo-mandibular joint scanographic findings and clinical manifestations of joint pain and sounds in temporo-mandibular disorders

    International Nuclear Information System (INIS)

    Exploring the association between magnetic resonance imaging, temporomandibular joint scanography and clinical manifestations of joint pain and sounds in patients with temporomandibular disorder. Patients and Methods: This study included 62 temporomandibular joints with internal derangement. Sagittal scanography and magnetic resonance imaging of these temporomandibular joints were obtained and reported blindly by the consensus of two radiologists. Results: No significant association was observed between clinical and scanographic findings with magnetic resonance imaging. The abnormal range of motion had significant relationship with pain (P=0.017) and sound (P=0.046). There was a strong association between sound and condylar flattening (P=0.007). Conclusion: It was demonstrated that joint pain and sounds were predictors of the abnormal range of motion in temporomandibular joint scanography. Sound could be heard more often in patients with condylar flattening, and temporomandibular joint scanographic findings as well as joint pain and sounds had limited value in the diagnosis of disk position or effusion.

    Full Text Available Fabrication of occlusal splints in centric relation for temporomandibular disorders (TMD patients is arguable, since this position has been defined for asymptomatic stomatognathic system. Thus, maximum intercuspation might be employed in patients with occlusal stability, eliminating the need for interocclusal records. This study compared occlusal splints fabricated in centric relation and maximum intercuspation in muscle pain reduction of TMD patients. Twenty patients with TMD of myogenous origin and bruxism were divided into 2 groups treated with splints in maximum intercuspation (I or centric relation (II. Clinical, electrognathographic and electromyographic examinations were performed before and 3 months after therapy. Data were analyzed by the Student's t test. Differences at 5% level of probability were considered statistically significant. There was a remarkable reduction in pain symptomatology, without statistically significant differences (p>0.05 between the groups. There was mandibular repositioning during therapy, as demonstrated by the change in occlusal contacts on the splints. Electrognathographic examination demonstrated a significant increase in maximum left lateral movement for group I and right lateral movement for group II (p0.05 in the electromyographic activities at rest after utilization of both splints. In conclusion, both occlusal splints were effective for pain control and presented similar action. The results suggest that maximum intercuspation may be used for fabrication of occlusal splints in patients with occlusal stability without large discrepancies between centric relation and maximum intercuspation. Moreover, this technique is simpler and less expensive.

    Sidebottom, A J; Salha, R

    2013-04-01

    This article summarises the rheumatoid diseases that particularly affect the temporomandibular joint (TMJ): psoriatic arthropathy, ankylosing spondylitis, and rheumatoid arthritis. Management is by a joint approach between rheumatologists and maxillofacial surgeons with a specific interest in diseases of the TMJ who give early surgical advice. Steroid injections, whilst useful in the short term, are not useful for long term or repeated treatment, and may lead to collapse of the joint and development of a deformed anterior open bite. These disorders should be managed primarily using standard conservative regimens, and failure to respond should lead to diagnostic or therapeutic arthroscopy and appropriate surgical treatment. When ankylosis develops or the joint collapses, a replacement joint should be considered and patients should be referred to an appropriately trained surgeon. PMID:22658606

    2012-04-01

    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.

  18. Epigenetics and Bruxism: Possible Role of Epigenetics in the Etiology of Bruxism.

    Science.gov (United States)

    Čalić, Aleksandra; Peterlin, Borut

    2015-01-01

    Bruxism is defined as a repetitive jaw muscle activity characterized by clenching or grinding of the teeth and/or bracing or thrusting of the mandible. There are two distinct circadian phenotypes for bruxism: sleep bruxism (SB) and awake bruxism, which are considered separate entities due to the putative difference in their etiology and phenotypic variance. The detailed etiology of bruxism so far remains unknown. Recent theories suggest the central regulation of certain pathophysiological or psychological pathways. Current proposed causes of bruxism appear to be a combination of genetic and environmental (G×E) factors, with epigenetics providing a robust framework for investigating G×E interactions, and their involvement in bruxism makes it a suitable candidate for epigenetic research. Both types of bruxism are associated with certain epigenetically determined disorders, such as Rett syndrome (RTT), Prader-Willi syndrome (PWS), and Angelman syndrome (AS), and these associations suggest a mechanistic link between epigenetic deregulation and bruxism. The present article reviews the possible role of epigenetic mechanisms in the etiology of both types of bruxism based on the epigenetic pathways involved in the pathophysiology of RTT, PWS, and AS, and on other epigenetic disruptions associated with risk factors for bruxism, including sleep disorders, altered stress response, and psychopathology.

    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.

    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. PMID:26149971

  3. 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 OBJECTIVES: The aim of this study was to assess the prevalence of Temporomandibular Disorders (TMD, using the Research Diagnostic Criteria for TMD (RDC/TMD in women with episodic and chronic migraine (M and CM, as well as in asymptomatic women. METHOD: Sample consisted of 61 women, being 38 with M and 23 with CM, identified from a headache outpatient center; we also investigated 30 women without headaches for at least 3 months (women without headache group - WHG. Assessment of TMD was conducted by a physical therapist who was blind to the headache status. RESULTS: The prevalence of TMD, assessed through the RDC, was 33.3% in the WHG, 86.8% in the M group and 91.3% of the CM group. Differences were significant when comparing M and CM groups with WHG (p0.05 as well as higher risk for TMD [odds ratio (OR=3.15, 95% confidence interval (CI 1.73-5.71 and OR=3.97, 95%CI 1.76-8.94]. CONCLUSION: Women with migraine are more likely to have muscular and articular TMD, suggesting that both disorders might be clinically associated, which demonstrate the importance of physical therapy assessment in the multidisciplinary team.

    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.

    Full Text Available Temporomandibular disorder (TMD is the general term used to describe the symptoms originated from temporomandibular joint region. The most common symptom of the disorder is pain during mandibular movement. Etiology of TMD is multifactorial. Several factors such as trauma, occlusal discrepancies, stress, parafunctions, hypermobility, and heredity can make one more vulnerable to this disorder. It has been reported that viola playing might be a predisposing factor for TMD. In this article, we present a 24 year old male patient suffering from TMD symptoms exacerbated by viola playing and emphasize that viola playing may be a powerful aggravating factor for TMD.

    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.

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.

    Practical Implications: Anxiety disorders are highly related to suicidal behaviors, particularly in children and adolescents. Additionally, awaken bruxism can often serve as an indicator of anxiety or stress. By recognizing bruxism as a possible manifestation of psychological distress, the dental practitioner may be able to direct patients to life-saving services like psychologists and crisis hotlines when appropriate.

  15. A clinical study of temporomandibular disorder. The value of bone scintigraphy as an aid to diagnosis

    International Nuclear Information System (INIS)

    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)

    Full Text Available Abstract Background The aim of this study was to evaluate the prevalence of signs and symptoms of temporomandibular disorders (TMD and oral parafunction habits among Saudi adolescents in the permanent dentition stage. Methods A total of 385 (230 females and 155 males school children age 12–16, completed a questionnaire and were examined clinically. A stratified selection technique was used for schools allocation. Results The results showed that 21.3% of the subjects exhibited at least one sign of TMD and females were generally more affected than males. Joint sounds were the most prevalent sign (13.5% followed by restricted opening (4.7% and opening deviation (3.9%. The amplitude of mouth opening, overbite taken into consideration, was 46.5 mm and 50.2 mm in females and males respectively. TMJ pain and muscle tenderness were rare (0.5%. Reported symptoms were 33%, headache being the most frequent symptom 22%, followed by pain during chewing 14% and hearing TMJ noises 8.7%. Difficulty during jaw opening and jaw locking were rare.

    Full Text Available Some studies have shown a relationship between temporomandibular disorders (TMD and dysphonia, as well as quality of life in oral health. OBJECTIVE: 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. MATERIAL AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.

  20. 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.

    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

    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.

    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).

  19. Imaging diagnosis of temporomandibular disorders (TMD). MR imaging of the disk of the temporomandibular joint

    International Nuclear Information System (INIS)

    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)

    Diagnostic Criteria for Temporomandibular Disorders" (RDC/TMD. Parafunctional habits are those not related to the execution of normal functions of stomatognatic system. Bruxism is characterized by nocturnal involuntary parafunctional activity of masticatory muscles, while clenching is considered as a diurnal parafunction involving this musculature, although this may also occur at night. OBJECTIVE: the goal of the present study was to evaluate the frequency of relates of diurnal and/or nocturnal oral parafunctions in patients with TMD in different diagnostic subgroups of RDC/TMD. METHODOLOGY: it has been used data from 217 patients that seek for treatment at TMD and Orofacial Pain Clinic of Petropolis Medicine School, being evaluated through questionnaire and physical examination that compose RDC/TMD. RESULTS: from 182 TMD patients studied, 76.9% has related some kind of parafunction, that could be diurnal, nocturnal or both. Diurnal parafunction was the most frequent related among TMD subgroups, present in 64.8% of cases against 55.5% of cases with relates of bruxism. Relate of both parafunctions was verified in 43.4% of TMD patients. CONCLUSION: regarding each diagnostic subgroup, relates of diurnal and nocturnal parafunctions has been more frequent in patients of miofascial pain group.

    International Nuclear Information System (INIS)

    The pathologic conditions that involve the TMJ are similar to those conditions that involve other joints in the body. Therefore, many of the radiologic characteristics are also similar. Nevertheless, because of the complex structure and function of this small joint, it is essential to know the variety of diseases that can involve the temporomandibular joint. It is also important to understand that functionally both TMJ's act as a single unit and that any alteration in function caused by a pathologic process on one side may lead to dysfunction on the contralateral side. It is essential that the radiologist is familiar with the principles of TMJ function as well as TMJ pathology. (orig.)

CONCLUSÃO: recomenda-se que a avaliação dos possíveis sinais e sintomas da DTM em crianças seja adotada como rotina durante o exame clínico inicial.INTRODUCTION: The etiology of temporomandibular disorders (TMD's is currently considered multifactorial, involving psychological factors, oral parafunctions, morphological and functional malocclusion. OBJECTIVES: In keeping with this reasoning, we evaluated children who seek preventive orthodontic treatment, to better understand their grievances and to assess the prevalence of TMD signs and symptoms in these patients. METHODS: Two examiners evaluated 65 children aged 6 to 11 years. RESULTS: In our sample, bruxism featured the highest prevalence rate, whereas atypical swallowing displayed the highest rate among predisposing factors. CONCLUSION: We therefore recommend that the evaluation of possible TMD signs and symptoms in children be adopted as routine in the initial clinical examination.

    [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.

    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.

    Temporomandibular disorders (TMD) consist of a group of pathologies that affect the masticatory muscles, temporomandibular joints (TMJ), and/or related structures. String instrumentalists, like many orchestra musicians, can spend hours with head postures that may influence the biomechanical behavior of the TMJ and the muscles of the craniocervicomandibular complex (CCMC). The adoption of abnormal postures acquired during performance by musicians can lead to muscular hyperactivity of the head and cervical muscles, with the possible appearance of TMD. Medical infrared thermography is a non-invasive procedure that can monitor the changes in the superficial tissue related to blood circulation and may serve as a complement to the clinical examination. The objective of this study was to use infrared thermography to evaluate, in one subject, the cutaneous thermal changes adjacent to the CCMC that occur before, during, and after playing a string instrument.

    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)

    2014-01-01

    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.

    International Nuclear Information System (INIS)

    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)

    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.

  8. Bone changes in the condylar head and mandibular fossa in patients with temporomandibular disorders. Helical CT observation

    International Nuclear Information System (INIS)

    In the present study, we investigated whether bone changes are present in sites impossible to observe by panoramic X-ray and Schuller's X-ray examination, namely the medial of the condylar head and mandibular fossa, in patients with type IV temporomandibular joint disorders. We observed the articular fossa using computed tomography, which is able to obtain detailed 3-dimensional information, in patients with type IV temporomandibular disorders. We examined 120 joints of 60 patiens who visited the Department of Oral Surgery, Osaka Medical College Hospital. Each condylar head was clearly visualized in panoramic X-ray and Schuller's X-ray examination findings, and shown to have possible changes unilaterally. Each joint was diagnosed as type IV, according to the diagnostic guidelines set by Japanese Society for Temporomandibular Joint, and further examined using helical CT. Changes in condylar head; We concluded that bone changes were present with considerable probability in the medial of condylar head in a manner similar to those found in the lateral and center of joints with type IV temporomandibular disorders. Changes in mandibular fossa; The bone changes occurred in various locations of the mandibular fossa, while they appeared significantly more frequently in the condylar head. We think that our finding will contribute to development of treatment strategies for temporomandibular disorders, as they clarify bone changes in sites previously unreported. (author)

    Objective The use of chewing-gum and piercing has become common among adolescents and might result in increased oral muscle activity and overloading. Aim To investigate the frequency of oral piercing and parafunctions in relation to symptoms of temporomandibular disorders (TMD) among adolescents. Materials and methods One hundred and twenty-four third level high school students, living either in a city or in a small town, enrolled in either science or media programmes, were included. The students completed a questionnaire regarding different parafunctions and symptoms of TMD. A clinical examination of the temporomandibular system and estimation of the tooth wear was performed in 116 students. Results Chewing-gum was used by 86% of the students (25% with a daily use) and 14% had an oral piercing. The science students used more chewing gum than the media students (p = 0.008), while the media students had more piercings (p temporomandibular joints and muscles (both p < 0.05). Oral piercing was associated with headache and muscle tenderness (both p < 0.05) and daily nail biting with headache (p < 0.05) and tooth wear (p = 0.004). Conclusions There is an association between use of chewing gum, nail biting, oral piercing, and symptoms of TMD. PMID:26621674

    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

    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.

    Salivary gland malignancy (SGM) can affect both major and minor glands and manifests clinically with various presentations. The most common type of SGM is mucoepidermoid carcinoma (MEC), which has been previously reported to be associated with symptomatology associated with temporomandibular disorders (TMD). This case report describes a patient with an aggressive form of MEC of the parotid gland that was initially diagnosed as TMD. In addition, the patient's MEC was diagnosed emergently based on development of acute clinical symptomatology. To the best of our knowledge, emergency route diagnosis of MEC affecting the parotid gland has not been previously reported in the literature. PMID:26782364

    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.

    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.

    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.

    Purpose 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). Materials and Methods 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. Results 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. Conclusion 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. PMID:27358820

  2. Clinical study in elderly patients with temporomandibular disorders. A comparison with patients in their 20s

    International Nuclear Information System (INIS)

    To evaluate the characteristics of temporomandibular disorders (TMD) in elderly patients, we performed a clinicostatistical study in 122 patients aged ≥60 years. Based on medical records, panoramic X-ray images, and MR images, clinical findings (sex-related differences, chief complaint, disease duration, frequency of complication, disorder type classification, joint sound (crepitation), maximum mouth opening, and occlusal support) and imaging findings (articular disc position in type IV, disc configuration, mandibular condyle bony changes) were compared between the elderly subjects and 125 patients in their 20s. As a result, significant differences were observed in disease duration, disorder type classification, and disc configuration, showing prolongation, increases in types I and IV, and an increase in cases of severe deformation, respectively, in the elderly patients. Therefore, management with consideration of these characteristics may be important in the diagnosis and treatment of TMD. (author)

    Full Text Available Introduction: The influence of psychological factors on temporomandibular disorders (TMD, such as depression, anxiety and stress has been very discussed in literature. However, there is no consensus about their influence on the clinical manifestation of TMD. Objective: To evaluate the evolution of minor psychiatric disorders and pain symptoms in patients with temporomandibular disorders (TMD treated with occlusal splints and rehabilitated with dental prosthesis. Material and methods: Sixty volunteers, both genders, aging from 20 to 65 years, diagnosed with TMD, were randomly selected within the university’s patient databank. The volunteers were divided into two groups: G1 - 30 males and G2 - 30 females. The volunteers underwent a standard clinical evaluation for TMD diagnosis. Psychological evaluations were performed through Goldberg’s General Health Questionnaire (GHQ, before and after 24 months of treatment. TMD treatment comprised occlusal splints and rehabilitated with dental prosthesis. The results were evaluated by Mantel-Haezel, Wilcoxon and Mann-Whitney statistical tests. Results: According to the criteria established by GHQ, the interpretation of the symptom scores should be applied based on gender, because the scores have different values for male and female, consequently no comparisons were made between the groups. There were significant statistical difference in G2 when the variables psychic stress (p = 0.002 and psychosomatic disorders (p = 0.007 were observed. In G1, the variables for psychosomatic disorders (p = 0.002 and general health (p = 0.021 were statistically significant. Significant differences were found in both groups for all the evaluated symptoms (p < 0.005. Conclusion: The used therapy positively interfered in the remission of symptoms and in the incidence of minor psychic disorders of TMD patients.

    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.

  10. Clinical Utility of bone Scan in the Diagnosis of Temporomandibular disorders

    International Nuclear Information System (INIS)

    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 99mTc 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(pmean+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.

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

    Full Text Available The objective of this study is to analyze the distribution of the most common diagnoses observed in patients with chronic temporomandibular disorders, based on the new diagnostic criteria (DC/TMD adopted in 2014. The previous Research Diagnostic Criteria (RDC/TMD adopted in 1992, consisted of three main groups of eight diagnostic subgroups and is currently transformed into two main groups and twelve subgroups, respectively. All subgroups correspond to the nomenclature of the ICD-10. The new clinical diagnostic indices are also modified. The analysis showed a prevalence of Pain-Related TMD compared with that of intra-articular disorders in ratio 57.89% to 42.10%. In Pain-Related TMD arthralgia was represented in 55% of cases; local myalgia - in 12%, myofascial pain - in 18%, myofascial pain with referral - in 14%, headache attributed to TMD - in 1%. In Intra-articular TMD disc displacement with reduction was found in 23% of the cases, disc displacement with reduction with intermittent locking - in 3%, disc displacement without reduction with limited opening - in 25%, disc displacement without reduction and without limited opening - in 8%. Degenerative diseases were found in 14.28%, and hypermobility and subluxations - in 26.98%. These analyzes differ and can only partly be compared with previous analyzes based on RDC system. The changes in the diagnostic criteria require new clinical studies in order to refine the picture of temporomandibular pathology in accordance with the modern views on the matter.

    Full Text Available 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 (, decreased quality of life (, and higher total sleep scores ( 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.

    The study aimed to assess the distribution of temporomandibular disorders (TMD) sub-types, psychological distress and psychosocial dysfunction in southern Chinese people seeking treatment for TMD using Research Diagnostic Criteria for TMD (RDC/TMD) and investigate potential cross-cultural differences in sub-type prevalence and psychosocial impact. Eighty-seven consecutive patients (77 females; 10 males) with a mean age of 39.3 years (s.d. 12.8) newly referred to the specialist TMD clinic at the Prince Philip Dental Hospital, Hong Kong over a 20-month period took part in the study. RDC/TMD history questionnaire and clinical assessment data were used to derive Axis I and II findings. Group I muscle disorders were the most common and found in 57.5% of patients. Group II (disc displacement) disorders were found in 42.5% and 47.1% of the right and left temporomandibular joints (TMJ) respectively. Group III disorders (arthralgia/arthrosis/arthritis) were revealed in 19.5% and 23.0% of right and left TMJ's respectively. In the Axis II assessment, 42.5% of patients had moderate/severe depression scores, 59.7% had moderate/severe somatization scores and based on graded chronic pain scores 15.0% had psychosocial dysfunction (grade III and IV). While acknowledging the small sample size, the distribution of RDC/TMD Axis I and II diagnoses was fairly similar in Chinese TMD patients compared with Western and other Asian patient groups. However, in Chinese patients, myofascial pain with limited jaw opening and TMJ disc displacement with reduction were more common and a significant number experienced psychological distress and psychosocial dysfunction. The findings have implications for the management of TMD in Chinese people. PMID:18254795

    Full Text Available Temporomandibular disorders (TMD are characterized by the presence of temporomandibular joint (TMJ and/or masticatory muscle pain and dysfunction. Low-level laser is presented as an adjuvant therapeutic modality for the treatment of TMD, especially when the presence of inflammatory pain is suspected. Objective: To systematically review studies that investigated the effect of low level laser therapy (LLLT on the pain levels in individuals with TMD. Material and Methods: The databases Scopus, embase, ebsco and PubMed were reviewed from January/2003 to October/2010 with the following keywords: laser therapy, low-level laser therapy, temporomandibular joint disorders, temporomandibular joint dysfunction syndrome, temporomandibular joint, temporomandibular, facial pain and arthralgia, with the inclusion criteria for intervention studies in humans. exclusion criteria adopted were intervention studies in animals, studies that were not written in english, Spanish or Portuguese, theses, monographs, and abstracts presented in scientific events. Results: After a careful review, 14 studies fit the criteria for inclusion, of which, 12 used a placebo group. As for the protocol for laser application, the energy density used ranged from 0.9 to 105 J/cm², while the power density ranged from 9.8 to 500 mW. The number of sessions varied from 1 to 20 and the frequency of applications ranged from daily for 10 days to 1 time per week for 4 weeks. A reduction in pain levels was reported in 13 studies, with 9 of these occurring only in the experimental group, and 4 studies reporting pain relief for both the experimental group and for the placebo. Conclusion: Most papers showed that LLLT seemed to be effective in reducing pain from TMD. However, the heterogeneity of the standardization regarding the parameters of laser calls for caution in interpretation of these results. Thus, it is necessary to conduct further research in order to obtain a consensus regarding the

  19. MR imaging of patients with temporomandibular disorders. Relationship between anterior disc displacement and disc deformity

    International Nuclear Information System (INIS)

    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 (T1-weight: sagittal and coronal) and fast spin echo (T2-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)

    2015-06-01

    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.

  2. Relationship between pain and effusion on magnetic resonance imaging in temporomandibular disorder patients

    International Nuclear Information System (INIS)

    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 chi2 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 (p0.05). 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.

    This article reports the orthodontic treatment of a 20-year-old patient with dental crowding and temporomandibular joint disorders (TMDs). The patient presented moderate anterior crowding with a Class I molar relationship and masticatory disturbance in the mandibular position induced by previous splint therapy. Orthodontic treatment with multi-bracket appliance was initiated to correct the anterior crowding in both dental arches, after the extraction of first premolars and third molars, and also to maintain the splint-induced position of the condyles. After 26 months of treatment, an acceptable occlusion was achieved without any TMD symptoms. After 18-month retention, flattening on the right condyle was observed, possibly as an adaptative remodeling. After 16-year retention period, the occlusion was maintained without recurrence of any TMD symptoms, indicating a long-term stability of occlusion and temporomandibular joint (TMJ) components. Our results suggest the possibility of compromised treatment in patients with TMD to achieve a long-term stability in occlusion and TMJ function. PMID:27556023

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

    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.

    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).

    Sleep bruxism (SB) is a repetitive jaw-muscle activity characterised by clenching or grinding of the teeth during sleep. Sleep bruxism activity is characterised by rhythmic masticatory muscle activity (RMMA). Many but not all RMMA episodes are associated with sleep arousal. The aim of this study was to evaluate whether transient oxygen saturation level change can be temporally associated with genesis of RMMA/SB. Sleep laboratory or home recordings data from 22 SB (tooth grinding history in the absence of reported sleep-disordered breathing) and healthy subjects were analysed. A total of 143 RMMA/SB episodes were classified in four categories: (i) no arousal + no body movement; (ii) arousal + no body movement; (iii) no arousal + body movement; (iv) arousal + body movement. Blood oxygen levels (SaO2 ) were assessed from finger oximetry signal at the baseline (before RMMA), and during RMMA. Significant variation in SaO2 over time (P = 0·001) was found after RMMA onset (+7 to +9 s). No difference between categories (P = 0·91) and no interaction between categories and SaO2 variation over time (P = 0·10) were observed. SaO2 of six of 22 subjects (27%) remained equal or slight increase after the RMMA/SB onset (+8 s) compared to baseline; 10 subjects (45%) slightly decreased (drop 0·01-1%) and the remaining (27%) decreased between 1% and 2%. These preliminary findings suggest that a subgroup of SB subjects had (i) a minor transient hypoxia potentially associated with the onset of RMMA episodes, and this (ii) independently of concomitant sleep arousal or body movements.

    Hypnosis modulates pain perception but the associated brain mechanisms in chronic pain conditions are poorly understood. Brain activity evoked by painful repetitive pin-prick stimulation of the left mental nerve region was investigated with use of fMRI in 19 patients with painful temporomandibular...... disorders (TMD) during hypnotic hypoalgesia and hyperalgesia and a control condition. Pain intensity and unpleasantness of the painful stimulation was scored on a 0-10 Numerical Rating Scale (NRS). NRS pain and unpleasantness scores during hypnotic hypoalgesia were significantly lower than in the control...... condition and significantly higher in the hypnotic hyperalgesia condition. In the control condition, painful stimulation caused significant activation of right posterior insula, primary somatosensory cortex (SI), BA21, and BA6, and left BA40 and BA4. Painful stimulation during hypnotic hyperalgesia...

    2008-08-01

    Full Text Available 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.

    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.

    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.

  16. Morphological changes of the mandibular condyle in patients with temporomandibular joint disorder using magnetic resonance imaging

    International Nuclear Information System (INIS)

    The morphological changes of the mandibular condyle in patients with temporomandibular joint disorder were studied. The subjects were 420 patients (103 males and 317 females, 8 to 80 years of age, mean age 39.8 years) who were clinically diagnosed as temporomandibular joint disorder. MR imaging was performed with a GE-Signa 1.5 Tesla MR imaging system using the body coil as a transmitter and 3-inch bilateral surface coils. The patients were examined by a multiplanar gradient echo technique in a closed-loop cine fashion on both sagittal and coronal planes. The results obtained were as follows: 1) Morphological changes of the mandibular condyle were detected in 47.0% of the patients. The predominant morphological changes were then formation of osteophyte and marginal proliferation (65.8%). 2) The incidence of morphological changes in the mandubular condyle did not show any significant difference between male and female, and tended to be higher in patients over 40 years of age, and the incidence in patients under 20 years of age was lower, compared to that in patients from 20 to 39 years of age. 3) The incidence of morphological changes in patients with anterior disk displacement without reduction was higher than in those with anterior disk displacement with reduction (P<0.001). The incidence of morphological changes in patients with rotational disk displacement was higher than in those with medial disk displacement (P<0.001). 4) The anterior translation of mandibular condyle was influenced more by anterior disk displacement rather than by morphological changes. From these results. it is suggested that simultaneous bilateral condyle pseudodynamic MR imaging was useful in the diagnosis of internal derangement, evaluation of morphological changes and assessment of motional abnormality of the condyle.

    Full Text Available Objective: 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. Material and Methods: 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. Results: 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. Conclusions: 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.

    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.

    Full Text Available 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 (p<0.001. The MMO significantly increased in patients with acute TMD (7.80±5.43 mm, p = 0.008 and in patients with chronic TMD (15.58±7.87 mm, p<0.001.Our study shows that laser acupuncture therapy improves the symptoms of treatment-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.

    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 chi2 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 (p<0.05). However, among the various types of provoked pain, pain on palpation 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.

    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.

    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 (TMDs) have a multifactorial etiology. Among others, parafunctions and oral habits have been suggested as important initiating and perpetuating factors. Playing a musical instrument that loads the masticatory system, like wind instruments and the violin or viola, has been suggested to be part of this group of etiological factors. However, the evidence base for this suggestion is lacking. Therefore, the aim of this study was to review the literature on the possible association between playing a musical instrument and developing and/or having a TMD. A PubMed search, using the query ['Music'(Mesh) AND 'Craniomandibular Disorders'(Mesh)], yielded 19 articles, 14 of which were included in this review. Six of 14 papers had a case-control or pre-test-post-test design; the remaining eight papers were case reports of expert opinions. The former papers were analysed and tabulated according to the PICO (Patient/population-Intervention-Control/comparison-Outcome/results) system; the latter ones were only summarised and tabulated. All articles with a case-control or pre-test-post-test design suggested a possible association between TMD and playing a musical instrument, especially the violin and viola. However, no clear-cut conclusion could be drawn as to whether playing a musical instrument is directly associated with TMD, or only in combination with other factors. More and better research on this topic is needed, as to enable a better counselling and possibly even a better treatment of the suffering musician. PMID:24702514

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.

    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

    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.

    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 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

    Full Text Available Abstract Background Oral health-related quality of life (OHRQoL in children and adolescents with signs and symptoms of temporomandibular disorder (TMD has not yet been measured. This study aimed to evaluate the validity and reliability of OHRQoL measure for use in children and preadolescents with signs and symptoms of TMD. Methods 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 (CPQ8-10 (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. Results 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 8-10 and 0.94 for CPQ11-14. For the overall CPQ8-10 and CPQ11-14 scales, the corrected item-total correlation coefficients ranged from 0

  1. Lateral pterygoid muscle volume and migraine in patients with temporomandibular disorders

    International Nuclear Information System (INIS)

    Lateral pterygoid muscle (LPM) plays an important role in jaw movement and has been implicated in Temporomandibular disorders (TMDs). Migraine has been described as a common symptom in patients with TMDs and may be related to muscle hyperactivity. This study aimed to compare LPM volume in individuals with and without migraine, using segmentation of the LPM in magnetic resonance (MR) imaging of the TMJ. Twenty patients with migraine and 20 volunteers without migraine underwent a clinical examination of the TMJ, according to the Research Diagnostic Criteria for TMDs. MR imaging was performed and the LPM was segmented using the ITK-SNAP 1.4.1 software, which calculates the volume of each segmented structure in voxels per cubic millimeter. The chi-squared test and the Fisher's exact test were used to relate the TMD variables obtained from the MR images and clinical examinations to the presence of migraine. Logistic binary regression was used to determine the importance of each factor for predicting the presence of a migraine headache. Patients with TMDs and migraine tended to have hypertrophy of the LPM (58.7%). In addition, abnormal mandibular movements (61.2%) and disc displacement (70.0%) were found to be the most common signs in patients with TMDs and migraine. In patients with TMDs and simultaneous migraine, the LPM tends to be hypertrophic. LPM segmentation on MR imaging may be an alternative method to study this muscle in such patients because the hypertrophic LPM is not always palpable.

    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.

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 (α.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 (χ2/df = 3.319, CFI = 0.978, TLI = 0.967, RMSEA = 0.058. The convergent validity (AVE = 0.513, CR = 0.878 and internal consistency (α = 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).

    The author has studied radiographic bony changes of mandibular condyle head in temporomandibular disorder patients using Oblique lateral transcranial projection, Orthopantomography, and Tomography. The bony change types and the frequencies of occurrence and the incidences of bony changes in three different radiographic techniques were examined. The coincidences of body change types between the Oblique lateral transcranial projection and the lateral part of Tomogram, the Orthopantomogram and the medial part of Tomogram were also examined. The results were as follows: 1. The mean age of patients was 31.7 years and under 40 years were 24 patients, women were 27 patients, men were 4 patients. 2. The observable cases of bony changes in all three radiographic techniques were 19 cases (50%) of 38 cases and the observable cases of bony changes in only Tomography were 5 cases (13.2%). 3. The most frequent radiographic bony change type was osteophyte and next orders were flattening, erosion, concavity. 4. The positional incidences of bony changes in Tomogram were 31 cases in lateral part and 27 cases in central part. 5. The coincidence of bony change types between the oblique lateral transcranial projection and the lateral part of Tomogram was 80%, and the coincidence between the Orthopantomogram and the medial part of Tomogram was 76.9%.

    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. PMID:26506809

    Although psychosocial factors and malocclusion are regarded as potential causes of temporomandibular disorders (TMD), the underlying pathogenesis is poorly understood. Recent studies suggest that substance P (SP), which has been associated with both psychosocial factors and malocclusion, and histamine, whose release can be induced by SP, may be implicated in the pathogenetic process. This study was designed to measure the concentration of histamine and SP in synovial fluid (SF) of both 38 patients with TMD and 11 healthy controls, and analyse the correlation between histamine and SP. Patients with TMD were divided into three subgroups: displaced disc with reduction (DDR), displaced disc without reduction (DDNR) and osteoarthritis (OA), with 10, 13, 15 subjects in every subgroup, respectively. After collecting SF samples, histamine and SP levels were measured by enzyme-linked immunosorbent assay analysis (ELISA) and calibrated by bicinchoninic acid (BCA)-quantified protein level in the samples. The results suggest that OA group presented a significantly higher level of both histamine and SP than DDNR, DDR and healthy control groups. Histamine or SP in DDR and DDNR groups tend to be higher than control group, but no significance was found. Painful TMJs show higher histamine and SP than painless TMJs. Correlation analysis reveals a significant correlation between histamine and SP concentrations. Collectively, this study showed the changes of histamine and SP in the SF from different stages of TMD and found a significant correlation between the two substances, suggesting their potential implication in the pathogenesis of TMD.

    The most common temporomandibular disorders (TMD) signs and symptoms are related to muscle sensitivity through palpation, restricted mouth opening, asymmetric mandibular movements, joint sounds, pain and otologic signs and symptoms. To date, counselling, occlusal splints, exercises, biofeedback and acupuncture are examples of conservative modalities proposed for TMD therapy. The aim of this systematic review was to investigate the effect of these conservative therapies for TMD on otologic signs and symptoms. The authors searched the following electronic databases published up to 1st May 2015: PubMed, LILACS, Scopus, Web of Science and Science Direct with no time or language limitations. Using a two-phase selection process, the authors identified 08 articles and used them to conduct a qualitative analysis. Methodological quality of each article was performed with the aid of 'Quality Assessment of a Cohort Study' and 'Quality Assessment of a Randomized Clinical Trial', developed by the Dutch Cochrane Centre, a centre of the Cochrane Collaboration. This systematic review showed in seven of the eight studies included that a total or partial resolution of otologic complains occurred after counselling, exercise therapies and occlusal splint therapy. Upon the limitations of the studies included in this systematic review, the present outcomes suggested that there is insufficient evidence in favour or against the conservative therapies for TMD on changes in otologic signs and symptoms. Thus, further studies with a higher level of evidence and more representative samples should be conducted to better understand the relationship of TMD therapy changes on otologic complains.

    This paper describes the evolution of different concepts of classifying and defining Temporomandibular Disorders (TMD) for both clinical and research settings. The literature is reviewed with respect to the utility and validity of the different questionnaire and examination procedures that have been used to assess TMD patients. The presented view is that many of these procedures have not been validated, that there is a lack of standardization in the use of the procedures themselves, and that an ideal method of classifying this broad group of patients into better-defined subgroups has not yet been developed. More standardized and better-defined research by trained and calibrated researchers is needed worldwide to elucidate these subgroups so that a better and widely agreed upon research classification system can be developed for widespread use. It also seems clear that as research requirements for defining TMD patient subgroups become more stringent over time, it may not be practical for the clinician to implement them on a day-to-day basis in his or her practice. As such, a practical utilitarian definition of the common subtype of TMD patients is also needed which parallels any research grouping, so that data from research are valuable and generalizable to the practicing clinician.

    Full Text Available Facial pain often persists long after any identifiable organic pathology has healed. Moreover, in a subgroup of patients with temporomandibular disorder (TMD, no treatment is effective. Knowledge of factors associated with persistent pain in TMD could help identify personalized treatment approaches. Therefore, we conducted a critical review of the literature for the period from January 2000 to December 2013 to identify factors related to TMD development and persistence. The literature findings showed that chronic TMD is marked by psychological distress (somatization and depression, affective distress, fear of pain, fear of movement, and catastrophizing and characteristics of pain amplification (hyperalgesia and allodynia. Furthermore, these factors seem to interact in TMD development. In addition, our review demonstrates that upregulation of the serotonergic pathway, sleep problems, and gene polymorphisms influence the chronicity of TMD. We conclude that psychological distress and pain amplification contribute to chronic TMD development, and that interactions among these factors complicate pain management. These findings emphasize the importance of multidisciplinary assistance in TMD treatment.

    Temporomandibular disorder (TMD) is a common condition that can be difficult to manage in physical therapy. A number of interventions, such as manual therapy, therapeutic exercise, and patient education have typically been used in some combination. However, the evidence regarding thrust manipulation of not only the local but also adjacent segments is sparse. Specifically, the use of cervicothoracic (CT) junction thrust manipulation has not previously been described in the management of individuals with TMD. In this case report, CT junction thrust manipulation, in addition to locally directed manual therapy, exercise, and postural education, was associated with immediate improvements in neck and jaw symptoms and function in a complex patient with TMD. The patient was seen for seven visits over the course of 2 months and demonstrated clinically significant changes in the neck disability index (NDI), the numeric rating of pain scale (NPRS), and the global rating of change (GROC) scale. The purpose of this report is to describe the successful physical therapy management of a patient with TMD utilizing manual therapy, including CT junction thrust manipulation, education, and exercise.

    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.

    Full Text Available Background. Temporomandibular disorders (TMDs are among the common musculoskeletal conditions affecting the individual. Anxiety plays an important role in the pathogenesis of TMD. Modern lifestyle and work environment bring to focus the role of anxiety in everyday life which is changing the demographics of diseases like TMD. This study compared the anxiety scores between TMD patients and normal subjects. Material and Methods. 505 individuals were included in the study who were divided into group 1 with 255 individuals presenting with signs and symptoms of TMD and group 2 with 250 normal individuals as controls. Hospital anxiety depression scale was used to calculate the anxiety scores. Fischer’s t test was used to compare the anxiety scores between the two groups. Results. 80% of individuals in group 2 and 44% in group 1 individuals had normal anxiety scores. 45% of the individuals in group 1 and 19% in group 2 had borderline anxiety scores. 11% of group 1 individuals and <1% of group 2 individuals demonstrated high anxiety scores. These results were statistically significant. Conclusion. Individuals with TMD exhibited higher levels of anxiety scores whereas significant number of control subjects exhibited normal anxiety scores.

    Full Text Available OBJECTIVE: The aims of this study were to compare the prevalence of temporomandibular disorders (TMD in individuals submitted to either orthodontic or ortho-surgical Class III malocclusion treatment and to assess the influence of occlusal aspects on TMD severity. MATERIAL AND METHODS: The sample consisted of 50 individuals divided into two groups, according to the type of treatment (orthodontic or orthodontic with orthognathic surgery. The presence of signs and symptoms of TMD was evaluated by an anamnestic questionnaire and a clinical examination, including TMJ and muscle palpation, active mandibular range of motion, joint noises and occlusal examination. RESULTS: Based on the anamnestic questionnaire, 48% had no TMD, 42% had mild TMD and 10% had moderate TMD. The presence and severity of TMD did not show any relationship with the type of orthodontic treatment (p>0.05. The chi-square test showed a positive association (p<0.05 between TMD and non-working side occlusal interferences. CONCLUSION: Based on the methodology used and the results obtained, it may be concluded that Class III orthodontic treatment was not associated with the presence of TMD signs and symptoms and the non-working side contacts can be occlusal factors of risk. There was no significant difference in TMD prevalence between the studied groups (orthodontically treated patients and patients treated with orthodontics followed by orthognathic surgery.

    Full Text Available Abstract Background The aim of this study was to test whether a reciprocal dose-response relation exists between frequency/severity of spinal pain and temporomandibular disorders (TMD. Methods A total of 616 subjects with varying severity of spinal pain or no spinal pain completed a questionnaire focusing on symptoms in the jaw, head and spinal region. A subset of the population (n = 266 were sampled regardless of presence or absence of spinal pain. We used two different designs, one with frequency/severity of spinal pain, and the other, with frequency/severity of TMD symptoms as independent variable. All 616 participants were allocated to four groups, one control group without spinal pain and three spinal pain groups. The subjects in the subset were allocated to one control group without TMD symptoms and three TMD groups. Odds ratios (ORs were calculated for presence of frequent TMD symptoms in the separate spinal pain groups as well as for frequent spinal pain in the separate TMD groups. Results The analysis showed increasing ORs for TMD with increasing frequency/severity of spinal pain. We also found increasing ORs for spinal pain with increasing frequency/severity of TMD symptoms. Conclusion This study shows a reciprocal dose-response-like relationship between spinal pain and TMD. The results indicate that these two conditions may share common risk factors or that they may influence each other. Studies on the temporal sequence between spinal pain and TMD are warranted.

    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.

    MR imaging is useful in the diagnosis of bilateral internal derangement of the temporomandibular joint. This study was performed to investigate the correlation between clinical symptoms and displacement of the bilateral articular disk in patients with temporomandibular joint disorders (TMJD). A series of 170 patients who had signs and symptoms of TMJDs (TMJ pain, TMJ sound, trismus) were examined bilaterally by MR imaging. One hundred twenty-six patients had only unilateral symptoms, but 55 (44%) of them showed bilateral disk displacement. Among 93 patients with unilateral TMJ pain, 89% showed disk displacement (22 TMJs with reduction, 61 TMJs without reduction) on the symptomatic side, and 44% showed disk displacement on the asymptomatic side. Among 53 patients with unilateral TMJ sound, 96% showed disk displacement (28 TMJs with reduction, 23 TMJs without reduction) on the symptomatic side, and 53% showed disk displacement on the asymptomatic side. In patients with severe trismus (interincisal opening distance <39 mm), unilateral or bilateral disk displacement without reduction was frequently found. The results indicate that examinations by MR imaging are important for the diagnosis of internal derangement of the temporomandibular joint. (author).

    Bruxism is a health problem consisting in grinding or tightly clenching the upper and lower teeth. Both the grinding and sliding lead to wear of the teeth and produce a noise during the night that is sufficiently loud to disturb the sleep of anyone sharing the bedroom. The tension produced causes problems in the muscles, tissues and other structures surrounding the jaw, ear pain, headaches, lesions to the teeth and disorders in the jaw joints.

    Screening for the various forms of bruxism in children and adolescents requires a sound knowledge of the physiopathology of this parafunction in addition to the etiologic and associated factors and comorbidities. The international literature contains various suggestions for suitable treatment. The optimal therapeutic approach often involves multidisciplinary management of these young patients. Sleep bruxism (SB) is a common sleep disorder which can cause serious problems to the stomatognathic system such as damaged teeth, headaches, muscle pain and TMD. Dental professionals are responsible for the detection and prevention of these harmful impacts on the patient's oral health. However, SB is much more than a question of worn teeth. Patients with SB consult for other medical comorbidities such as nighttime breathing problems, insomnia, attention deficit hyperactivity disorder, depression, moodiness and gastroesophogeal reflux before any course of treatment is initiated. If a comorbidity is diagnosed, the treatment approach will be aimed in the first instance at the medical disorder, while concurrently managing the repercussions of SB. On the other hand, in as far as the majority of young bruxers cease to grind their teeth before adolescence or adulthood, it is feasible to adopt wait-and-see and non-interventionist strategies for young children. However, it is preferable to have a better understanding of SB, notably on account of its potential association with psychological disorders during childhood. Daytime bruxism is characterized by teeth clenching (TC). First-line treatment involves encouraging patients to monitor their harmful parafunctional behavior and, consequently, change and cease it. This protocol is not always easy to apply, particularly in younger children. In such cases, cognitive-behavioral treatments and biofeedback techniques can also be used in daytime bruxism.

    Oral splints have been frequently used in the treatment of bruxism to protect teeth and periodontium from damage, but the mechanism of action and efficacy of oral splints remain controversial. It has been suggested that they can be used to treat bruxism, based on the assumption that the device can eliminate or remove occlusal interference. Currently there are no reliable data to support the assumption of occlusion as an etiologic factor for bruxism, because several other factors have a role i...

      The purpose of this study was to find the relationship among the joint status, pain and effusion in patients with temporomandibular joint disorders. Materials included 406 patients (812 joints) with clinical records and bilateral TMJ MRIs in TMJ clinic, Yongdong Severance Hospital. All joints were classified in 4 groups in MR images according to the disc status of joint; normal disc position, disc displacement with reduction (DDsR), and also 2 groups according to the bony status of joint; normal bony structure and osteoarthrosis. MR evidence of joint effusion was categorized in 4 groups according to its amount. To determine the relationship between joint pain and joint effusion, 289 patients with unilateral TMJ symptoms were selected from total materials. Joint effusion was found 8.0% in normal disc position, 32.6% in DDcR, and 59.2% in DDsR (83.1% in early state and 23.1% in late stage). Joint effusion was found 39.7% in osteoarthrosis and 35.0% in normal bony structure. Joint effusion was more found in the painful joints (49.8%) than in the painless joints (22.4%) (p<0.001). Joint effusion in the early stage of DDsR only was more found significantly in painful joints (91.9%) than in painless joints (62.1%) (p<0.001). MR evidence of joint effusion might be related to disc displacement regardless of the presence of osteoarthrosis, and the early stage of DDsR was found more frequently combined with joint effusion and joint pain.

Methods: Between July 2010 and January 2011, course Coordinators/Directors of all dental schools duly registered at the Ministry of Education were invited to answer a questionnaire on topics related to OFP/TMD teaching in their institutions. Results: Fifty-three dental schools representatives answered the questionnaire. The study of pain mechanisms was found to cover an average of less than 10% of the courses' total time. Pharmacology, Endodontics and Physiology were identified as the departments usually responsible for addressing pain mechanisms in dental courses. Psychosocial aspects were found to occupy a very small proportion in the syllabi, while most of the content referred to biological or somatic aspects. OFP/TMD is addressed by a specific department in only 28.4% of the participating dental schools, while in most cases (46.3%, OFP/TMD is under the responsibility of the Prosthodontics department. Only 38.5% of respondents indicated that they had a specialist OFP/TMD teacher in their Schools. Conclusion: Among the Brazilian dental schools participating in the study, the teaching of OFP/TMD was found to be insufficient, segmented or with an extremely restricted focus. This initial assessment indicates that Curricular Guidelines for the study of OFP/TMD at undergraduate dental schools should be developed and implemented to facilitate their appropriate inclusion into the curricula and in specific pedagogical projects.

      Accumulated evidence from experimental animal models suggests that neuroplastic changes at the dorsal horn are critical for the maintenance of various chronic musculoskeletal pain conditions. However, to date, no study has specifically investigated whether neuroplastic changes also occur at this level in humans. Using brain imaging techniques, we sought to determine whether anatomical changes were present in the medullary dorsal horn (spinal trigeminal nucleus caudalis) in subjects with the chronic musculoskeletal pain. In twenty-two subjects with painful temporomandibular disorders (TMDs) and forty pain-free controls voxel based morphometry of T1-weighted anatomical images and diffusion tensor images were used to assess regional grey matter volume and microstructural changes within the brainstem and, in addition, the integrity of ascending pain pathways. Voxel based morphometry revealed significant regional grey matter volume decreases in the medullary dorsal horn, in conjunction with alterations in diffusivity properties, namely an increase in mean diffusivity, in TMD subjects. Volumetric and mean diffusivity changes also occurred in TMD subjects in regions of the descending pain modulation system, including the midbrain periaqueductal grey matter and nucleus raphe magnus. Finally, tractography revealed altered diffusivity properties, namely decreased fractional anisotropy, in the root entry zone of the trigeminal nerve, the spinal trigeminal tract and the ventral trigeminothalamic tracts of TMD subjects. These data reveal that chronic musculoskeletal pain in humans is associated with discrete alterations in the anatomy of the medullary dorsal horn, as well as its afferent and efferent projections. These neural changes may be critical for the maintenance of pathological pain. PMID:25979666

      Full Text Available Objectives: This study investigated whether playing wind instruments has adverse effects on musculoskeletal functions among junior high school students who play in music clubs. Material and Methods: The study included 210 junior high school students (35 boys, 175 girls belonging to 1 of 4 different school clubs that practiced playing wind instruments more than 6 days/week. The mean age of the participants was 14 years. The study was performed using a questionnaire survey and an electromyographic examination of jaw and cervical muscle activities during playing wind instruments. Results: The prevalence of temporomandibular disorders (TMD among the children playing woodwind (WW or brass wind (BW instruments was higher than in those playing non-wind (NW instruments. Long duration of playing WW with a reed mouthpiece or BW with a small mouthpiece was suggested to affect the incidence of TMD, which was more marked in girls than in boys, irrespective of height or weight. Muscle activity in the masseter muscle during playing an instrument was significantly higher in the BW with a small mouthpiece group than in the NW group (p < 0.05. In cervical muscles, muscle activity of both the sternocleidomastoid and trapezius muscles was higher during playing BW than in the case of other instruments, and activity in the sternocleidomastoid muscle was significantly higher in the BW with a small mouthpiece group than in the case of other instrument groups (p < 0.05. Conclusions: Playing wind instruments may have adverse effects on musculoskeletal functions among junior high school students playing in music clubs as compared with playing NW instruments. The prevalence of TMD among the students playing wind instruments was higher than in those playing other instruments. Long duration of playing those instruments affects musculoskeletal function, and this effect is more marked in girls than in boys, irrespective of height or weight.

      The aim of this study was to explore the association between signs and symptoms of temporomandibular disorders (TMD) and orthodontic treatment need in orthodontically untreated children and adolescents. One thousand five hundred and ninety-seven subjects aged 11-19 years, without previous orthodontic history, from sixteen randomly selected public schools in Zagreb, Croatia, were examined. Malocclusion characteristics were assessed by using the criteria proposed by Bjork et al., the Dental Aesthetic Index, and the Aesthetic Component of Index of Orthodontic Treatment Need. Data on TMD signs/symptoms and parafunctional behaviour were obtained by means of questionnaire and clinical examination, respectively. Multiple logistic regression models were used for analysis. Twenty-two percent of children and young adolescents had one or more signs of TMD, ranging from 17% in age of 11 years up to 24% in age of 19. There was poor correlation between presence of TMD and orthodontic treatment need. Multiple logistic regression models showed that Class III, crowding and spacing were related to mandibular deflection on opening. Ectopic eruption was related to TMJ clicking, and severely tipped teeth with reduced mouth opening. Headaches presented a positive relationship with reverse overjet and severe rotations, and tooth wear with crowding, spacing and lateral openbite. Age, female gender and parafunctional habits were related to several TMD signs. Although logistic regression models were statistically significant (p < 0.05) malocclusions, parafunctional behaviours, age and gender accounted for less than 20% of the variability in TMD signs/symptoms. TMD signs and symptoms seemed to be poorly related to malocclusions or treatment needs. PMID:26040083

      Veronika Vielsmeier

      Full Text Available OBJECTIVE: Tinnitus is considered to be highly heterogeneous with respect to its etiology, its comorbidities and the response to specific interventions. Subtyping is recommended, but it remains to be determined which criteria are useful, since it has not yet been clearly demonstrated whether and to which extent etiologic factors, comorbid states and interventional response are related to each other and are thus applicable for subtyping tinnitus. Analyzing the Tinnitus Research Initiative Database we differentiated patients according to presence or absence of comorbid temporomandibular joint (TMJ disorder complaints and compared the two groups with respect to etiologic factors. METHODS: 1204 Tinnitus patients from the Tinnitus Research Initiative (TRI Database with and without subjective TMJ complaints were compared with respect to demographic, tinnitus and audiological characteristics, questionnaires, and numeric ratings. Data were analysed according to a predefined statistical analysis plan. RESULTS: Tinnitus patients with TMJ complaints (22% of the whole group were significantly younger, had a lower age at tinnitus onset, and were more frequently female. They could modulate or mask their tinnitus more frequently by somatic maneuvers and by music or sound stimulation. Groups did not significantly differ for tinnitus duration, type of onset (gradual/abrupt, onset related events (whiplash etc., character (pulsatile or not, hyperacusis, hearing impairment, tinnitus distress, depression, quality of life and subjective ratings (loudness etc.. CONCLUSION: Replicating previous work in tinnitus patients with TMJ complaints, classical risk factors for tinnitus like older age and male gender are less relevant in tinnitus patients with TMJ complaints. By demonstrating group differences for modulation of tinnitus by movements and sounds our data further support the notion that tinnitus with TMJ complaints represents a subgroup of tinnitus with clinical

      Full Text Available Background: Migraine and temporomandibular disorders (TMDs are reported to be associated. However, there are no reports on the association among migraines, TMDs and changes in body posture. Objectives : To assess changes in body posture in women suffering migraines with or without TMD compared with a control group. Method: Sixty-six women with a mean age of 18 to 45 years participated in this study. The groups were composed of 22 volunteers with migraine and TMD (MTMD, 22 volunteers with migraines without TMD (MG and 22 women in the control group (CG. Static posture was assessed by photogrammetry, and 19 angles were measured. Results: Postural asymmetry was observed in the face for 4 angles measured on the frontal plane in the MG group and for 4 angles of the trunk in the MG and MTMD groups with respect to CG. However, for comparisons between MTMD and CG, clinical relevance was identified for two angles of the sagittal plane (Cervical and Lumbar Lordosis, Effect Size - ES - moderate: 0.53 and 0.60. For comparisons between the MG and CG, the clinical relevance/potential was verified for three angles with moderate ES (ES>0.42. The clinical relevance when comparing MTMD and CG was identified for four angles of facial symmetry head inclination (ES>0.54 and for two angles between MG and CG (ES>0.48. Conclusion : The results demonstrated the presence of postural changes compared with a control group in women with migraines with or without TMD, and there were similar clinically relevant postural changes among the patients with migraines with and without TMD.

      Full Text Available Aims/Objectives: To evaluate the prevalence and severity of temporomandibular disorders (TMD and presence of psychological factors (i.e.,anxiety and depression levels in dental undergraduate students. Second purpose was to assess the association and correlation between TMD degree and psychological factors viz. anxiety and depression. Materials and methods: The sample comprised of 400 Dental undergraduatestudents aged 18- 25 years, including both the genders. TMD degree was evaluated using an anamnestic questionnaire (modified version of Helkimo’s anamnestic index. Morphologic occlusion was evaluated according to Angle classification. The Hospital Anxiety and Depression Scale (HADS was used to assess of levels of anxiety (HADSa and depression (HADSd in the dental undergraduate students. Results: Onbasisof the TMD anamnestic index, 74% of students were TMD free. 24.5% of subjects presented with mild degree of TMD and only 1.5% of subjects presented with moderate degree of TMD. According to the results obtained from HADSa, 35.3% of subjects presented with mild anxiety level, 13.8% with moderate anxiety level, and only 1.3% with severe anxiety level. According to the results obtained from HADSd, 10.3% of subjects presented with mild depression level and only 2.3% with moderate depression level. A definite association between TMD degree and Anxiety level (HADSa was found. A definite association between TMD degree and Depression level (HADSd was found. Therewas significant association between TMD degree and occlusion. Conclusions: On the basis of anamnestic index, this study revealed a 26% TMD prevalence in the dental undergraduate students included in the study; majority of cases being of mild degree. Both anxiety and depression were found to be associated with TMD degree/severity. Both anxiety and depression are weakly correlated with TMD in the present study.

    • Dysregulation of the autonomous nervous system in patients with temporomandibular disorder: a pupillometric study.

      Directory of Open Access Journals (Sweden)

      Annalisa Monaco

      Full Text Available The role of the autonomic nervous system (ANS was recently investigated in Temporomandibular disorders (TMD. Several authors argue that in subjects with TMD there is a dysregulation of ANS. Recent literature support that Pupillometry is a simple non-invasive tool to study ANS. The aim of this study was to investigate the relationship between TMD and ANS activity using pupillometry recording in Infrared light at rest Mandible Position (RP; Infrared light at Forced Habitual Occlusion (FHO; Yellow-green light at RP; Yellow-green light at FHO. Forty female subjects were enrolled: 20 case patients showed TMD based on the Research Diagnostic Criteria for TMD, and 20 control patients, aged matched, had no signs or symptoms of TMD. Statistical analysis was performed on average pupil size. Ratio between pupil size in FHO and RP (FHO/RP ratio and yellow-green and infrared (light/darkness ratio lighting were carried out. Within group differences of pupil size and of "ratio" were analyzed using a paired t test, while differences of pupil size between groups were tested using an unpaired t test. Statistical comparisons between groups showed no significant differences of absolute values of pupil dimension in RP and FHO, both in yellow-green and in infrared lighting. In addition, there were no significant differences within groups comparing RP and FHO in yellow-green light. In within group comparison of pupil size, differences between RP and FHO were significant in infrared conditions. Control subjects increased, whereas TMD patients decreased pupil size at FHO in infrared lightening. FHO/RP ratio in darkness and light/darkness ratio in RP were significantly different between groups. Taken together, these data suggest that TMD subjects have an impairment of the sympathetic-adrenergic component of the ANS to be activated under stress. The present study provides preliminary pupillometric data confirming that adrenergic function is dysregulated in patients with

    The aim of this study was to evaluate the relationship between pain intensities and psychosocial characteristics in middle-aged and older patients with temporomandibular disorders (TMDs) and burning mouth syndrome (BMS). Subjects were selected according to the Research Diagnostic Criteria for TMD (n = 705) and International Association for the Study of Pain criteria for BMS (n = 175). Patients were then divided into two age groups: 45-64 years (middle-aged, Group A) and 65-84 years (older, Group B). Pain intensity and depression and somatization scores were evaluated in both groups. In BMS patients, present and worst pain intensities were significantly higher in Group B than in Group A {4.6 [95% confidence interval (CI) = 4.0-5.2] vs. 3.5 [95% CI = 3.1-3.9] and 5.9 [95% CI = 5.2-6.4] vs. 5.0 [95% CI = 4.5-5.6], respectively; P < 0.05}, with no difference observed in TMD patients. The depression and somatization scores were significantly higher in Group A than in Group B among BMS patients [0.57 (95% CI = 0.45-0.69) vs. 0.46 (95% CI = 0.34-0.59) and 0.537 (95% CI = 0.45-0.63) vs. 0.45 (95% CI = 0.34-0.55); P < 0.05], with no difference observed in TMD patients. The results of the present study indicate that pain intensities and psychosocial characteristics in BMS appear to differ between middle-aged and older patients. PMID:26666859

    Full Text Available Objective. To quantify effects on occlusion and temporomandibular function of mandibular distal extension removable partial dentures in shortened dental arches. Methods. Subjects wearing mandibular extension removable partial dentures (n=25 were compared with subjects with shortened dental arches without extension (n=74 and with subjects who had worn a mandibular extension removable partial denture in the past (n=19. Subjects with complete dentitions (n=72 were controls. Data were collected at baseline and at 3-, 6-, and 9-year observations. Results. Occlusal activity in terms of reported awareness of bruxism and occlusal tooth wear of lower anterior teeth did not differ significantly between the groups. In contrast, occlusal tooth wear of premolars in shortened dental arches with or without extension dentures was significantly higher than in the controls. Differences amongst groups with respect to signs and symptoms related to temporomandibular disorders were not found. Occlusal support of the dentures did not influence anterior spatial relationship. Occlusal contacts of the denture teeth decreased from 70% for second premolars via 50% for first molars, to 30% for second molars. Conclusions. Mandibular distal extension removable partial dentures in moderate shortened dental arches had no effects on occlusion and temporomandibular function.

  3. Study on temporomandibular joint disorders by bone scintigraphy and bone metabolic markers (ICTP, PICP) in synovial fluid

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate bone metabolic condition in imaging findings of temporomandibular joint disorders (TMD) using bone scintigraphy, which has a high sensitivity to bone metabolism, and two bone metabolic markers: pyridinoline cross-linked carboxy-terminal telopeptide of type I collagen (ICTP) and carboxy-terminal propeptide of type I procollagen (PICP) which influence both the formation and absorption of bone. The subjects were 92 patients (18 male, 74 female, mean age 40.3±18.2 years of age, 112 temporomandibular joints (TMJs)) with TMD who underwent bone scintigraphy using 99mTc-methylene diphosphonate sodium (MDP) and/or had their concentration of bone metabolic markers (ICTP and PICP) measured in synovial lavage fluid by a radioimmunoassay kit using competitive inhibition. Synovial lavage fluid was a mixture of synovial fluid and physiological saline, obtained by irrigation of the superior joint compartment of TMD patients. Sixteen female controls (mean age 42.7±15.7 years of age) with no symptoms of TMD, but who had other diseases and who underwent bone scintigraphy, were selected. The position and configuration of the articular disk of patients with TMD were diagnosed by MRI and/or double contrastarthrography. All patients were examined for morphological bone change of the TMJ by tomography and were evaluated using both a positive ratio and an accumulation ratio (radioactivity counts of TMJ region/radioactivity counts of neck soft tissue region) by bone scintigraphy. We obtained the following results and conclusions. All the temporomandibular joints with morphological bone change showed an increase in accumulation by bone scintigraphy. Some of the temporomandibular joints without morphological bone change also showed an increase in accumulation. There were no statistically significant differences between disk position, disk configuration and accumulation ratio. Most of the temporomandibular joints, which had an increase in accumulation

  4. Usefulness of quantitative SPECT in unilateral temporomandibular joint disorder: correlation with signs and symptoms

    International Nuclear Information System (INIS)

    The aims of this study was to compare the diagnostic accuracy of Conventional Radiography (CR). Radionuclide Angiography (RNA). Planar Scintigraphy (PS) and Single Photon Emission Computed Tomography (SPECT) for the evaluation of temporomandibular joint (TMJ) disorder; and to show whether technetium-99m-MDP uptake on quantitative SPECT correlated with the symptom and/or signs. Three Phase Bone Scintigraphy (TPBS) and SPECT of both TMJ were performed in 51 patients (M : F = 10 : 41 mean age= 30.4 :28.6, respectively) with unilateral TMJ disorder after an intravenous injection of 25 mCi (925 MBq) of 99mTc-MDP. Data were analyzed by creating three regions of interest (ROIs) over designated areas both on the PS and SPECT: Lesion (L). Non-lesion(NL) which is contralateral to L and Background (BG). L/ NL and L/BG (=[(L-BG)/500,000] x 100 (%)] ratios were calculated for each patients. L/NL ratios on SPECT were compared according to the symptom/signs or not. There was a fair correlation of L/N values between three slice-and seven slice-added SPECT images (r=0.5124, p=0.006, y=0.5588 + 0.5414X). The percentages of symptoms or signs were: pain (76.5%), mouth opening limitation (49.0%), joint sound (39.2%), discomfort (43.1%), headache(27.5%), neck stiffness (21.6%), closed lock (5.9%) / tenderness (47.1%), joint click (54.9%) and limitation of maximum mouth opening (45.1%). The Sensitive of SPECT(86.3%) was better than PS(66.7%), RNA(27.5%), and CR(26.3%). According to the presence of symptom/sign or not, comparative analysis of L/NL ratios on SPECT showed a fair correlation in pain (1.16 : 1.11) mouth opening limitation (1.21 : 1.09), joint sound (1.19 : 1.08), discomfort (1.22 : 1.09), headache (1.19: 1.13), tenderness (1.16 : 1.14) and limitation of maximum mouth opening (1.16 : 1.13), but little correlation in neck stiffness (1.12 : 1.15), closed lock (1.06 : 1.15), dislocation (1.08 : 1.15) joint click (1.12 : 1.18). In conclusion, quantitative SPECT is the noninvasive

    The aims of the present study were to investigate the prevalence of temporomandibular disorder (TMD) in a group of patients with Parkinson’s disease (PD), and to analyze oral health according to the severity of the disease. [Methods] Signs and symptoms of TMD were evaluated using the Research Diagnostic Criteria for Temporomandibular Disorders, and oral health impact was measured using the Oral Health Impact Profile. The unpaired Student’s t-test was used to compare groups with and without TMD. Pearson’s correlation coefficients were calculated to determine correlations between the level of functional independence and oral health impact. Fisher’s exact test was used to test the association between TMD and the severity of symptoms of PD. [Results] Fifty-nine individuals with PD were analyzed. The prevalence of TMD was 20.33%. No statistically significant associations were found between TMD and the severity of PD. Oral health impact was considered weak, but a statistically significant difference between groups with and without TMD was found for psychological disability (p = 0.003). No significant correlation was found between the level of functional independence and oral health impact. [Conclusion] The prevalence of TMD among patients with Parkinson’s disease was 20.33%. A statistically significant difference between groups with and without TMD was found regarding the psychological disability domain. PMID:25931752

    Background The main objective of this paper is to analyze the prevalence of each of the different clinical subtypes of temporomandibular disorders (TMD) in a sample of patients with this pathology. In addition, a second objective was to analyze their distribution according to gender. Material and Methods To this end, the results of 1603 patients who went to the Unit of Temporomandibular Disorders in the Córdoba Healthcare District because they suffered from this pathology were analyzed. In order to diagnose them, the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were applied, analyzing the different Axis I subtypes (myopathy, discopathy and arthropathy) and obtaining the combined Axis I for each patient and the relation of all these variables according to gender. The null-hypothesis test confirmed the lack of connection between the gender variable and the different subtypes in the clinical analysis, and between the former and the combined Axis I of the RDC/TMD. Results The prevalence was high for the muscle disorders subtype in general, showing an 88.7% prevalence, while the presence of discopathies or arthropathies was much lower. Among discopathies, the most frequent ones were disc displacements with reduction, with 39.7% and 42.8% for the left and right temporomandibular joints (TMJ), respectively, while the prevalence of arthropathies was 26.3% for the right TMJ and 32.9% for the left TMJ. The bivariate analysis on the connection with gender reveals a p≥ 0.05 value for the muscle and arthralgia subtypes. Conclusions The patients seen at the TMD Unit where mostly middle-aged women whose main clinical axis subtype was the muscle disorder subtype. For their part, both discopathies and arthropathies, although present, are much less prevalent. Key words:RDCTMD, axis I, orofacial pain, temporomandibular disorders, gender. PMID:26615508

    The classification of most chronic pain disorders gives emphasis to anatomical location of the pain to distinguish one disorder from the other (eg, back pain vs temporomandibular disorder [TMD]) or to define subtypes (eg, TMD myalgia vs arthralgia). However, anatomical criteria overlook etiology, potentially hampering treatment decisions. This study identified clusters of individuals using a comprehensive array of biopsychosocial measures. Data were collected from a case-control study of 1031 chronic TMD cases and 3247 TMD-free controls. Three subgroups were identified using supervised cluster analysis (referred to as the adaptive, pain-sensitive, and global symptoms clusters). Compared with the adaptive cluster, participants in the pain-sensitive cluster showed heightened sensitivity to experimental pain, and participants in the global symptoms cluster showed both greater pain sensitivity and greater psychological distress. Cluster membership was strongly associated with chronic TMD: 91.5% of TMD cases belonged to the pain-sensitive and global symptoms clusters, whereas 41.2% of controls belonged to the adaptive cluster. Temporomandibular disorder cases in the pain-sensitive and global symptoms clusters also showed greater pain intensity, jaw functional limitation, and more comorbid pain conditions. Similar results were obtained when the same methodology was applied to a smaller case-control study consisting of 199 chronic TMD cases and 201 TMD-free controls. During a median 3-year follow-up period of TMD-free individuals, participants in the global symptoms cluster had greater risk of developing first-onset TMD (hazard ratio = 2.8) compared with participants in the other 2 clusters. Cross-cohort predictive modeling was used to demonstrate the reliability of the clusters. PMID:26928952

    Full Text Available INTRODUCTION: In some cases, conservative treatment of internal derangements of the Temporomandibular Joint (TMJ is considered little responsive. Thus, it is necessary to accomplish treatments that aim at reducing pain and improve patients' functions who present arthrogenic temporomandibular disorders. OBJECTIVE: This study, by means of a systematic review of the literature, aimed to analyze the effectiveness of intra-articular injections with corticosteroids and sodium hyaluronate for treating internal derangements of the TMJ. METHODS: Carry out a research in the following databases: MEDLINE, Cochrane, EMBASE, Pubmed, Lilacs, and BBO, considering publications issued between 1966 and October of 2010, focusing on randomized or quasi-randomized controlled clinical trials, single or double-blind. RESULTS: After applying the inclusion criteria we collected 9 articles, 7 of which were randomized controlled double-blind clinical trials and 2 randomized controlled single-blind clinical trials. CONCLUSION: After analyzing the literature, it was found that intra-articular injection with corticosteroids and sodium hyaluronate seems to be an effective method for treating internal derangements of the TMJ. However, further randomized controlled clinical trials, with representative samples and longer follow-up time must be carried out in order to assess the real effectiveness of this technique.

    Full Text Available OBJECTIVE: To compare head positioning and cervical spine alignment between individuals with and without temporomandibular disorders (TMDs, by means of positional evaluation using photographs, radiographs and visual observation, and to investigate whether the type of TMD influences head posture and cervical spine positioning. METHODS: Ninety randomly chosen women were diagnosed using the research diagnostic criteria for TMDs (RDC/TMD by a trained examiner and were divided into three groups: Group 1, with a diagnosis of myofascial dysfunction (group I of RDC axis I; Group 2, with mixed TMD (groups I, II and III of RDC axis I; and Control, without TMD. Following this, the participants were photographed in frontal and lateral views by a single examiner. To produce these photos, the following anatomical points were marked out on the skin: occipital protuberance, C4, C7, acromioclavicular joint and sternoclavicular joint. From these points, different angles were analyzed by means of the ALCimagem-2000 application. These same photos were then evaluated qualitatively (visual evaluation. Next, lateral teleradiography and radiography of the cervical spine was requested. The examiner was blind when analyzing the images. To compare the results, the chi-squared test and analysis of variance were used, with significance levels of 5%. RESULTS: Regardless of the method used, the results revealed that head and cervical spine posture did not differ between the groups with and without TMD, independent of the diagnostic group. CONCLUSION: The posture of individuals with myogenic or arthrogenous TMD does not differ from the posture of individuals without TMD. The presence of TMD does not influence the head and cervical spine posture.OBJETIVO: Comparar o posicionamento da cabeça e o alinhamento da coluna cervical em indivíduos com e sem DTM, por meio da avaliação postural por fotografias, radiografias e por observação visual e verificar se o tipo de DTM

Questionários foram aplicados a 2.396 universitários, dos quais 73,7% mulheres (21±5 anos e 26,3% homens (22±4 anos. Determinado o nível de severidade dos sinais e sintomas da DTM, os dados foram tratados estatisticamente, com nível de significância de 5%. Maior prevalência de sinais e sintomas de DTM foi constatada para o sexo feminino (73,03%. Na região Centro-Oeste não foi observada diferença significante entre estudantes com sinais e sintomas de DTM moderada e severa; mas aí há mais probabilidade de encontrar universitários com sinais e sintomas severos do que nas demais regiões. A região Sul apresentou maior porcentagem de estudantes com sinais e sintomas, porém com menor severidade que nas demais regiões. No Nordeste e no Sul, é mais provável encontrar universitários sem sinais e sintomas que universitárias. Pode-se concluir que a porcentagem de universitários não-pacientes portadores de algum nível de severidade de sinais e sintomas da DTM foi maior que a de não-portadores, em todas as regiões. Diferentes regiões apresentam diferentes probabilidades de se encontrarem universitários com algum sinal ou sintoma de DTM.The aim of this study was to assess prevalence of temporomandibular disorders (TMD signs and symptoms in non-patients from different Brazilian geographic areas.

    Ganglion cysts are common pseudocystic masses, whereas those arising from the temporomandibular joint (TMJ) are rare entities. We report a case of ganglion cyst of the right TMJ with symptomatic bilateral TMJ internal derangement in a 24-year-old man. Disk repositioning using bone anchors and excision of the ganglion cyst were performed. A unique characteristic of inflammatory infiltrates was revealed in the specimen, and the relationship between these 2 distinct entities and probable pathogenesis of infectious involvement are discussed.

    Patients with temporomandibular disorders (TMD) and/or orofacial pain (OFP) frequently experience poor sleep quality or suffer from comorbid sleep disorders. Study results suggest that in chronic pain patients, an improvement in sleep quality critically influences the outcomes of interventions on mood and pain. Yet, only a few studies have systematically sought to evaluate the sleep quality of TMD/OFP patients. Standardized and validated self-reported instruments designed for screening sleep ...

    The purpose of this study was to evaluate and correlate the clinical, magnetic-resonance imaging (MRI), and surgical findings in 47 patients with temporomandibular joint (TMJ) disorders. 51 TMJs (24 right, 27 left) were operated on, because 4 patients underwent treatment of both TMJs. The best correlation between MRI and surgical findings was noted in connection with position of the disk. This was surgically confirmed altogether in 88% of cases (45/51). The clinical diagnosis was confirmed by surgical findings in 75% of cases of anterior dislocation of the disk with reduction and 89% of cases of anterior dislocation of the disk without reduction. Bone changes noted by MRI were confirmed by surgery in 71% of cases. MRI was excellent especially relating to disk position and changes in disk morphology. The results show also that there are findings using MRI, e.g. of joint effusion, which cannot be confirmed during surgery. (orig.)

  19. The validity of clinical findings for diagnosing temporomandibular disorders in patients from different age and gender groups

    International Nuclear Information System (INIS)

    This study was to clarify the diagnostic accuracy of clinical findings for internal derangement of the temporomandibular joint (TMJ) compared with that of magnetic resonance imaging. A series of 4559 patients (879 male and 3680 female, mean age 32.7 years; range 8-85 years;) with temporomandibular disorders were clinically examined by un unspecified number of dentists. All patients underwent magnetic resonance imaging (MRI). The clinical findings that characterize disc displacement, anterior disc displacement with reduction (ADDwR) and anterior disc displacement without reduction (ADDwoR) are pain, clicking sound and limitation of maximum mouth opening. These clinical findings were compared to the MRI interpretation, which was used as the gold standard for diagnosis of temporomandibular disorders to define the diagnostic accuracy, specificity, sensitivity, positive predictive value and negative predictive value of clinical findings. The prevalence of clinical finding was 3990 joints (43%) with pain, 2775 joints (30%) with clicking sound and 1731 patients (38%) with limitation of opening. Three thousands forty seven joints were diagnosed as having a normal disc position, 510 joints with sideways disc displacement, 2312 joints with ADDwR, 3239 joints with ADDwoR on MR image. The sensitivity of clinical findings was considerably low: sensitivity was 0.48 for pain versus internal derangement, 0.51 for clicking sound versus ADDwR, 0.62 for limitation of opening versus ADDwoR. The sensitivity was higher in the younger group for clicking sound versus ADDwR, but sensitivity was higher in the older group for limitation of opening versus ADDwoR. The diagnostic accuracy based on clinical findings of internal derangement of TMJ was found to be correlated with age. This study has been that the overall diagnostic accuracy of the clinical findings to determine the status of the joint is about 50-60%. The status of the joint could not be accurately determined by clinical findings

    Background Bruxism is a disorder of jaw-muscle activity characterised by repetitive clenching or grinding of the teeth which results in discomfort and damage to dentition. The two clinical manifestations of the condition (sleep and awake bruxism) are thought to have unrelated aetiologies but are palliated using similar techniques. The lack of a definitive treatment has prompted renewed interest in biofeedback, a behaviour change method that uses electronic detection to provide a stimulus when...

  5. The temporomandibular joint

    International Nuclear Information System (INIS)

    Whilst the temporomandibular joint is in many ways unique, it is subject to all the diseases and disorders found in joints in other parts of the human skeleton. By far the most common disorder is injury, followed by arthropathy, acute and chronic dislocations, ankylosis, and in rare instances, neoplasms. The diagnosis and management of the temporomandibular joint are the primary responsibility of the oral surgeon. Nevertheless, this anatomical region is an area in which the cooperation of medical and dental disciplines may be required for the satisfactory conclusion of treatment. The more so when the disease process involves either associated psychosomatic illness or malignancy. The mainstay of the diagnosis is a careful radiological examination of the joint. There exists a delicate relationship between the dentition, the muscles of mastication, and the temporomandibular articulation, which is controlled by arthrokinetic reflex activity of the branches of the 5th cranial nerve. Imbalance between one or more of the components of this integrated system frequently leads to disturbances in function. Pain-dysfunction disorders constitute the larger part of temporomandibular joint disturbances generally encountered

    Objective The purpose of this retrospective study was to investigate the relationship between oral habits and temporomandibular joint (TMJ) bony change of temporomandibular disorder (TMD) patients. Methods One hundred and six TMD patients diagnosed according to Research Diagnostic Criteria (RDC/TMD) were selected. All the patients had undergone cone beam computed tomography (CBCT) imaging of TMJ, and their oral habits had been investigated. The associations between oral habits and TMJ radiographic findings were analysed. Results Among 106 patients, the incidence of bruxism, clenching, chewing on one side and being fond of hard food were high. Preferring to hard food increased the risk of ill -defined cortical bone change. Hobby of hard food increased the risk of bony changes in the anterolateral and posterolateral part of the condyle, as well as in the articular tubercle. Chewing on one side could increase the risk of bony changes in the anteromedial aspect of articular fossa. Conclusion Oral habits of TMD patients were associated with type and position TMJ bony change.%目的 研究颞下颌关节病患者口腔不良习惯与颞下颌关节髁突骨质改变之间的关系.方法 选取诊断为颞下颌关节紊乱病的患者106例,问卷调查患者的口腔不良习惯,并行双侧颞下颌关节锥形束CT成像,分析患者口腔不良习惯与颞下颌关节髁突骨质影像学改变的相关性.结果 106例患者中,口腔不良习惯以偏侧咀嚼、紧咬牙、夜磨牙和喜食硬物较常见.经统计学分析,喜食硬物是出现髁突骨皮质模糊消失型改变的危险因素(P =0.019,OR=2.570).喜食硬物是髁突前外侧(P =0.025,OR =2.298)、髁突后外侧(P =0.023,OR =2.692)及关节结节(P=0.020,OR =3.067)易出现骨质改变的危险因素.偏侧咀嚼习惯则是关节窝前内侧(P=0.013,OR =0.311)易出现骨质改变的危险因素.结论 口腔的不良习惯与颞下颌关节骨质改变的类型及部位有一定相关性.

    To evaluate the effect of adding transcranial direct current stimulation (tDCS) to exercises for chronic pain, dysfunction and quality of life in subjects with temporomandibular disorders (TMD). Participants were selected based on the RDC/TMD criteria and assessed for pain intensity, pressure pain threshold over temporomandibular joint and cervical muscles and quality of life. After initial assessment, all individuals underwent a 4-week protocol of exercises and manual therapy, together with active or sham primary motor cortex tDCS. Stimulation was delivered through sponge electrodes, with 2 mA amplitude, for 20 min daily, over the first 5 days of the trial. A total of 32 subjects (mean age 24.7 ± 6.8 years) participated in the evaluations and treatment protocol. Mean pain intensity pre-treatment was 5.5 ± 1.4 for active tDCS group, and 6.3 ± 1.2 for sham tDCS. Both groups showed a decrease in pain intensity scores during the trial period (time factor--F(4.5,137.5) = 28.7, P 0.05). Pressure pain thresholds decrease and improvement in quality of life were also noticeable in both groups, but again without significant differences between them. Absolute benefit increase was 37.5% (CI 95%: -15.9% to 90.9%), and number needed to treat was 2.66. This study suggests that there is no additional benefit in adding tDCS to exercises for the treatment of chronic TMD in young adults. PMID:25891021

    Full Text Available Abstract Background Current methods for identifying patients with pain hypersensitivity are sufficiently complex to limit their widespread application in clinical settings. We assessed the reliability and validity of a simple multi-modal vibrotactile stimulus, applied using an electric toothbrush, to evaluate its potential as a screening tool for central sensitization. Methods Fourteen female temporomandibular disorders (TMD subjects with myofascial pain (RDC/TMD Ia or Ib and arthralgia (RDC/TMD IIIa were compared to 13 pain-free controls of matched age and gender. Vibrotactile stimulus was performed with an electric toothbrush, applied with 1 pound pressure for 30 seconds in four locations: over the lateral pole of the temporomandibular joint, masseter, temporalis, and mid-ventral surface of forearm. Pain intensity (0–10 was recorded following the stimulus at 0, 15, 30, and 60 seconds. Test-retest reliability was assessed with measurements from 8 participants, taken 2–12 hours apart. Case versus control differentiation involved comparison of area under the curve (AUC. A receiver operating characteristic (ROC curve was used to determine cutoff AUC scores for maximum sensitivity and specificity for this multi-modal vibrotactile stimulus. Results Test-retest reliability resulted in an ICC of 0.87 for all 4 pooled sites. ROC-determined AUC cutoff scores resulted in a sensitivity of 57% and specificity of 92% for all 4 pooled sites. Conclusion The electric toothbrush stimulus had excellent test-retest reliability. Validity of the scores was demonstrated with modest sensitivity and good specificity for differentiating TMD pain patients from controls, which are acceptable properties for a screening test.

  9. Relationship between anterior disc displacement with/without reduction and effusion in temporomandibular disorder patients using magnetic resonance imaging

    International Nuclear Information System (INIS)

    This study was performed to evaluate the relationship between anterior disc displacement and effusion in temporomandibular disorder (TMD) patients using magnetic resonance imaging (MRI). The study subjects included 253 TMD patients. 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 MRI findings, temporomandibular joint (TMJ) disc positions were divided into 3 subgroups: normal, anterior disc displacement with reduction (DWR), and anterior disc displacement without reduction (DWOR). The cases of effusion were divided into 4 groups: normal, mild (E1), moderate (E2), and marked effusion (E3). Statistical analysis was made by the Fisher's exact test using SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). The subjects consisted of 62 males and 191 females with a mean age of 28.5 years. Of the 253 patients, T1- and T2-weighted images revealed 34 (13.4%) normal, DWR in 103 (40.7%), and DWOR in 116 (45.9%) on the right side and 37 (14.6%) normal, DWR in 94 (37.2%), and DWOR in 122 (48.2%) joints on the left side. Also, T2-images revealed 82 (32.4%) normal, 78 (30.8%) E1, 51 (20.2%) E2, and 42 (16.6%) E3 joints on the right side and 79 (31.2%) normal, 85 (33.6%) E1, 57 (22.5%) E2, and 32 (12.7%) E3 on the left side. There was no difference between the right and left side. Anterior disc displacement was not related to the MRI findings of effusion in TMD patients (P>0.05).

    Full Text Available Occlusal stabilization appliances or splints are the most widely employed method for treatment of temporomandibular disorders (TMD. Magnetic Resonance Imaging (MRI is the most indicated imaging modality to evaluate the components of the temporomandibular joint (TMJ. Forty patients with signs and symptoms of temporomandibular disorders were treated with splints for a mean period of 12 months, comprising regular semimonthly follow-ups. After stabilization of the clinical status, occlusal adjustments and MRI evaluation were performed. It was concluded that the success of this kind of treatment are related to the total (70% or partial improvement (22.5% of painful symptomatology and to the functional reestablishment of the craniomandibular complex. The MRI allowed evaluation and also the conclusion that the splints provide conditions for the organism to develop means to resist to the temporomandibular disorders by means of elimination of several etiologic factors. Moreover, after treatment the patients are able to cope with disc displacements with larger or smaller tolerance.A placa estabilizadora é o mais difundido método de tratamento das disfunções têmporo-mandibulares.

    International Nuclear Information System (INIS)

    The oblique lateral transcranial projection (OLTP) of the temporomandibular joint (TMJ) is widely used for the diagnosis of TMJ disease. The OLTP is a simple and valuable technique for the lateral projection of the TMJ, but is sometimes reveals a complex radiographic findings due to the overlapping of the pars petrosa and the mastoid process to the TMJ. We have recently applied a photographic subtraction technique to the OLTP for reduction of the complex radiographic findings in the OLTP. The purpose of this study is to know the value of the photographic subtraction technique in the OLTP fundamentally. The results obtained are as follows: 1) The shape of the condyle was clearly demonstrated by the subtraction technique. 2) Diagnostic ability on disease of the condyle was increased by applying the subtraction technique. 3) Location of the condyle in the fossa was easily detected by the subtraction technique.

    Full Text Available El diagnóstico de las alteraciones que afectan a la articulación craneomandibular (ACM debe basarse en la información obtenida a través de la anamnesis médica, de la exploración física y de los factores psiocoemocionales presentes en el paciente. También es importante constatar los síntomas dolorosos y disfuncionales presentes, así como los problemas auditivos, del habla y de la deglución entre otros que le puedan aquejar. La valoración integral del complejo articular debe incluir los tejidos orofaciales, la función muscular y neurológica, el estudio de la oclusión y de los movimientos mandibulares y la identificación de los posibles hábitos parafuncionales. Si bien todo lo anterior es imprescindible en muchas ocasiones debemos apoyarnos en las diferentes técnicas de diagnóstico por la imagen para poder etiquetar el cuadro clínico que aqueja al paciente. En el presenta trabajo revisamos y actulizamos los conceptos referentes al diagnóstico por la imagen de los trastornos que afectan a esta articulación.Clinical history, exploration and anamnesis about depressive -anxious symptoms are the basis of diagnosis of temporomandibular disorders. It’s also very important to know about pain, loss of function of temporomandibular joint, swallowing and talking. We should consider temporomandibular joint as a syndrome and is necessary to include an exploration of orofacial tissues, muscles, nerves and parafunctions. After the anamnesis and exploration, it’s necessary to perform some test, mainly based in imaging techniques, in order to reach a correct diagnosis. In this paper we review the importance of imaging in the diagnosis of temporomandibular disorders.

    Little is known about the epidemiological characteristics of sleep and awake bruxism (SB and AB) in adolescents. The aims of the study were: to assess the prevalence rates of self-reported SB and AB in Israeli adolescents; to determine the associations between SB/AB and several demographical, exogenous and psychosocial factors in Israeli adolescents; and to investigate the possible concordance between SB and AB. The study made use of a questionnaire. The study population included 1000 students from different high schools in the centre of Israel. Prevalence of self-reported SB and AB in the Israeli adolescents studied was 9·2% and 19·2%, respectively. No gender difference was found regarding the prevalence of SB and AB. Multiple variable regression analysis revealed that the following predicting variables were related to SB: temporomandibular joint sounds (P = 0·002) and feeling stressed (P = 0·001). The following predicting variables were related to AB: age (P = 0·018), temporomandibular joint sounds (P = 0·002), oro-facial pain (P = 0·006), and feeling stressed (P = 0·002) or sad (P = 0·006). A significant association was found between SB and AB; that is, an individual reporting SB had a higher probability of reporting AB compared with an individual who did not report SB (odds ratio = 5·099). Chewing gum was the most common parafunction reported by adolescents. The results of this study demonstrate that self-reports of AB and SB are common in the Israeli adolescents population studied and are not related to gender. The significant correlation found between SB and AB may be a confounding bias that affects proper diagnosis of bruxism through self-reported questionnaires only. PMID:26968152

  3. Condylar bony changes in patients with temporomandibular disorders: a CBCT study

    International Nuclear Information System (INIS)

    Diagnosis of osteoarthritis most commonly depends on clinical and radiographic findings. The present study attempted to observe the bony changes in temporomandibular joint (TMJ) patients from all age groups. The first-visit clinical records and cone beam computed tomography (CBCT) data of 440 TMJs from 220 consecutive TMJ patients were reviewed retrospectively. The most frequent condylar bony change observed was sclerosis (133 joints, 30.2%) followed by surface erosion (129 joints, 29.3%), flattening of the articular surface (112 joints, 25.5%), and deviation in form (58 joints, 13.2%), which included 33 TMJs in a cane-shape, 16 with a lateral or medial pole depression, 6 with posterior condylar surface flattening, and 3 with a bifid-shaped condyle. Fifty-three joints (12.0%) showed hypoplastic condyles but only 1 joint showed hyperplasia. Osteophyte was found in 35 joints (8.0%) and subcortical cyst in 24 joints (5.5%), 5 of which had surface erosion as well. One hundred nineteen joints (27.0%) had only one kind of condylar bony change, 66 joints (15.0%) had two, 52 joints (11.8%) had three, 12 joints (5.0%) had four, and 6 joints (1.4%) had five kinds of condylar bony changes at the same time. Eighty-five (65.9%) of 129 joints with surface erosion had pain recorded at the chief complaint. With more widespread use of CBCT, more specific or detailed guidelines for osteoarthritis are needed.

    The pathologic conditions that involve the TMJ are similar to those conditions that involve other joints in the body. Therefore, many of the radiologic characteristics are also similar. Nevertheless, because of the complex structure and function of this small joint, it is essential to know the variety of diseases that can involve the temporomandibular joint. It is also important to understand that functionally both TMJ's act as a single unit and that any alteration in function caused by a pathologic process on one side may lead to dysfunction on the contralateral side. It is essential that the radiologist is familiar with the principles of TMJ function as well as TMJ pathology. (orig.) [German] Die Krankheitsbilder, die zu einer Mitbeteiligung der Kiefergelenke fuehren, unterscheiden sich prinzipiell nicht von jenen, welche die uebrigen Gelenke im Koerper betreffen. Aus diesem Grund sind auch die radiologischen Veraenderungen im Prinzip aehnlich. Aufgrund der komplexen Morphologie und Funktion des Kiefergelenks ist es jedoch wichtig, die Vielfalt von Erkrankungen zu kennen, welche zu morphologischen und funktionellen Veraenderungen am Kiefergelenk fuehren koennen. Durch die funktionelle Einheit beider Kiefergelenke kann jede einseitige Erkrankung in weiterer Folge auch zur Dysfunktion der kontralateralen Seite fuehren. Der Radiologe sollte mit den Prinzipien der Funktionen sowie mit der Vielfalt der pathologischen Veraenderungen der Kiefergelenke vertraut sein. (orig.)

    The present study examined if unilateral pain from temporomandibular disorders (TMD) was associated with the occlusion contacts and surface electromyographic (SEMG) activities of jaw-closing muscles. Eleven patients with unilateral TMD pain and 20 healthy volunteers who all had Angle's Class-I occlusions were enrolled. The numbers and load distributions of the occlusion contacts and the SEMG activities of the anterior temporalis (TA) muscles and masseters muscles (MM) during maximal voluntary clenching (MVC) in the centric and eccentric positions were simultaneously recorded on both sides. The pain was not associated with occlusal contact numbers or load distributions. The SEMG activities of the pain-side TA and bilateral MM were lower during centric MVC compared with controls. The SEMG activities of the non-pain-side TA and the normalized SEMG activities of the bilateral TAs and MMs were higher during protrusive MVC (pocclusal contacts, but the patients with TMD had TA and MM SEMG activities during different tasks that differed from controls and that did not seem related to the pain side.

    [Purpose] To assess the association between the oclusal characteristics, headache, parafunctional habits and clicking sounds and signs/symptoms of TMD in adolescents. [Subjects] Adolescents between 14 and 18 years of age. [Methods] The participants were evaluated using the Helkimo Index and a clinical examination to track clicking sounds, parafunctional habits and other signs/symptoms of temporomandibular disorder (TMD). Subjects were classified according to the presence or absence of headache, type of occlusion, facial pattern and type of bite. In statistical analyse we used the chi-square test and Fisher's exact test, with a level of significance of 5%. [Results] The sample was made up of 81 adolescents with a mean age of 15.64 years; 51.9% were male. The prevalence of signals/symptoms of TMD was 74.1%, predominantly affecting females. Signals/symptoms of TMD were significantly associated with clicking sounds, headache and nail biting. No associations were found between signals/symptoms of TMD and angle classification, type of bite and facial pattern. [Conclusion] Headache is one of the most closely associated symptoms of TMD. Clicking sounds were found in the majority of cases. Therefore, the sum of two or more factors may be necessary for the onset and perpetuation of TMD. PMID:24259787

    Neck pain is the most common musculoskeletal complaint among computer office workers. There are several reports about the coexistence of neck pain and temporomandibular disorders (TMD). However, there are no studies investigating this association in the context of work involving computers. The purpose of this study was to verify the association between TMD and neck pain in computer office workers. Fifty-two female computer workers who were divided into two groups: (i) those with self-reported chronic neck pain and disability (WNP) (n = 26) and (ii) those without self-reported neck pain (WONP) (n = 26), and a control group (CG) consisting of 26 women who did not work with computers participated in this study. Clinical assessments were performed to establish a diagnosis of TMD, and craniocervical mechanical pain was assessed using manual palpation and pressure pain threshold (PPT). The results of this study showed that the WNP group had a higher percentage of participants with TMD than the WONP group (42·30% vs. 23·07%, χ(2) = 5·70, P = 0·02). PPTs in all cervical sites were significantly lower in the groups WNP and WONP compared to the CG. Regression analysis revealed TMD, neck pain and work-related factors to be good predictors of disability (R(2) = 0·93, P workplace conditions. Consequently, this study attempted to emphasise the importance of considering work activity for minimising neck pain-related disability. PMID:26732204

    Full Text Available Aim: The purpose of this study was to find out the prevalence of temporomandibular disorder (TMD in a sample of university students and its relationship to gender, occlusion, and psychological factors. Materials and Methods: The sample comprised 196 subjects, aged 18-25 years. The TMD degree was evaluated using an anamnestic questionnaire. Morphologic occlusion was evaluated according to Angle classification (classes I, II, and III. The Hospital Anxiety and Depression Scale (HADS, a 14-item self-administered rating scale developed specifically to identify anxiety and depression in nonpsychiatric medical outpatients, was used to assess the levels of anxiety (HADSa and depression (HADSd. Statistical Analysis: The incidence of TMD level, malocclusion, anxiety, and depression in both genders was calculated as percentages. Association between TMD degree and occlusion, HADSa, and HADSd was tested using the Chi-square test. Results: According to our results, 50% of the subjects had TMD, but it was of moderate or severe degree in only 9.18% of them. No statistically significant association could be found between TMD and gender or occlusion. TMD was found to have statistically significant association with HADSa but not with HADSd. Conclusion : A high prevalence of TMD was found in this student population; however, most of the cases could be classified as mild. Of the variables studied, only HADSa had a statistically significant association with TMD.

    Full Text Available Background: Tinnitus is one of the otologic symptoms commonly reported to be associated with temporomandibular disorder (TMD, and questions regarding its nature and cause continue to plague the clinical and research community.Objectives: The current pilot study aimed to investigate the clinical signs and symptoms of presenting tinnitus in a group of individuals with TMD (group A, and compare them with a group with tinnitus but without TMD (group B. Twenty participants were included in the study, 10 from each group.Methods: All participants underwent basic audiological as well as ear, nose and throat (ENT evaluations to establish group A and group B. For tinnitus assessment, all participants completed a tinnitus survey questionnaire, and their tinnitus was evaluated using tinnitus matching procedures.Results: Findings revealed clinically relevant differences in attributes of tinnitus in patients with and without TMD. Most of the participants in group A matched their tinnitus to a 6 000 Hz tone or noise, at lower intensity levels than participants in group B, although these results were not statistically significant. Participants in group A associated their tinnitus with a single sound whereas some participants in group B associated it with more than one sound. More participants in group B reported the duration of their tinnitus as constant.Conclusions: Tinnitus may occur in patients with TMD, and be of high frequency. This highlights the importance of thorough assessment for patients with tinnitus as this might have implications for diagnosis and management.

The results were as follows; 1. The mean condylar angulation in control group and patient group was 21.72 ± 6.48 degree, 20.13 ± 9.14 degree respectively and there was no significant difference between two groups. 2. The mean depth of cut was 6.63 ± 0.38 cm in control group and 6.57 ± 0.46 cm in patient group. 3. Mean height and width of condylar head were 6.66 ± 1.83 mm, 12.42 ± 0.49 mm in control group and 6.22 ± 1.36 mm, 11.93 ± 1.92 mm in patient group. 4. The mean height of articular fossa was 10.20± 2.04 mm in control group and 9.89± 1.98 mm in patient group. The mean width of articular fossa was 21.08 ± 2.08 mm in control group and 21.24 ± 3.03 mm in patient group. 5. In centric occlusion the superior joint space was largest (4.15 ± 0.93 mm), followed by the posterior joint space (2.99 ± 0.97 mm) and the anterior joint space (2.70 ± 0.73 mm) in control group. The superior joint space (3.47 ± 1.31 mm) and posterior joint space (3.47 ± 7.07 mm) were same in patient group. There was significant difference in left superior joint spaces between two groups (p<0.05). 6. The condylar position in articular fossa was displaced anteroinferiorly (0.99 ± 3.65 mm anteriorly, 1.75 ± 1.01 mm inferiorly) in control group and posteroinferiorly (3.20 ± 4.69 mm posteriorly, 1.25 ± 1.87 mm inferiorly) in patient group with 1 inch opening.

    The authors describe two studies of special interest to clinicians and clinical researchers. Both are randomized controlled studies, exclusively focused on female patients. The first study tests whether a year-long weekly group intervention including hypnosis can reduce cancer pain among women with metastatic breast cancer. Findings suggest the intervention slowed the increase in reported pain over a 12-month period relative to controls. The second study examines the effect of hypnosis in women suffering from temporomandibular disorder (TMD), with a special focus on function as well as pain. Hypnosis reduced TMD pain as measured by a numerical-rating scale. PMID:20799126

    Full Text Available Abstract Background Pain due to temporomandibular disorders (TMDs often has the same clinical symptoms and signs as other types of orofacial pain (OP. The possible presence of serious neurological and/or systemic organic pathologies makes differential diagnosis difficult, especially in early disease stages. In the present study, we performed a qualitative and quantitative electrophysiological evaluation of the neuromuscular responses of the trigeminal nervous system. Using the jaw jerk reflex (JJ and the motor evoked potentials of the trigeminal roots (bR-MEPs tests, we investigated the functional and organic responses of healthy subjects (control group and patients with TMD symptoms (TMD group. Method Thirty-three patients with temporomandibular disorder (TMD symptoms and 36 control subjects underwent two electromyographic (EMG tests: the jaw jerk reflex test and the motor evoked potentials of the trigeminal roots test using bilateral electrical transcranial stimulation. The mean, standard deviation, median, minimum, and maximum values were computed for the EMG absolute values. The ratio between the EMG values obtained on each side was always computed with the reference side as the numerator. For the TMD group, this side was identified as the painful side (pain side, while for the control group this was taken as the non-preferred masticatory side (non-preferred side. The 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles were also calculated. Results Analysis of the ratios (expressed as percentages between the values obtained on both sides revealed a high degree of symmetry in the bR-MEPs % in the control (0.93 ± 0.12% and TMD (0.91 ± 0.22% groups. This symmetry indicated organic integrity of the trigeminal root motor fibers and correct electrode arrangement. A degree of asymmetry of the jaw jerk's amplitude between sides (ipJJ%, when the mandible was kept in the intercuspal position, was found in the TMD group (0.24% ± 0.14% with a

    This study investigated the efficacy of combining low-level laser therapy (LLLT) with oral motor exercises (OM-exercises) for rehabilitation of patients with chronic temporomandibular disorders (TMDs). Eighty-two patients with chronic TMD and 20 healthy subjects (control group) participated in the study. Patients were randomly assigned to treatment groups: GI (LLLT + OM exercises), GII (orofacial myofunctional therapy-OMT-which contains pain relief strategies and OM-exercises), and GIII (LLLT placebo + OM-exercises) and GIV (LLLT). LLLT (AsGaAl; 780-nm wavelength; average power of 60 mW, 40 s, and 60 ± 1.0 J/cm²) was used to promote analgesia, while OM-exercises were used to reestablish the orofacial functions. Evaluations at baseline (T1), after treatment immediate (T2), and at follow-up (T3) were muscle and joint tenderness to palpation, TMD severity, and orofacial myofunctional status. There was a significant improvement in outcome measures in all treated groups with stability at follow-up (Friedman test, P  0.05). Intergroup comparisons showed that all treated groups had no difference in tenderness to palpation of temporal muscle compared to GC at follow-up (Kruskal-Wallis test, P < 0.01). Moreover, GI, GII, and GIII showed no difference from GC in orofacial functional condition (T2 and T3) while they differed significantly from GIV (P < 0.01). In conclusion, LLLT combined with OM-exercises was more effective in promoting TMD rehabilitation than LLLT alone was. Similar treatment results were verified with the OMT protocol. PMID:27085322

  17. Serial contrast-enhanced MRI of the condyle and posterior disk attachment for assessing temporomandibular joint disorders

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the usefulness of serial contrast-enhanced magnetic resonance imaging (SCE-MRI) in assessing temporomandibular joint disorders (TMDs). SCE-MRI was performed for 114 patients with TMD. As controls, 50 asymptomatic joints of patients with unilateral symptoms were examined. Peak signal intensity ratio (pSIR) was calculated referring to signal intensity of precontrast images of the condyle (CON) and posterior disk attachment (PDA). Relationships among pSIR, existence of disease, stage of disk displacement, and clinical stages of disease were studied. Mean pSIRs of CON and PDA were significantly higher in affected joints (CON: 1.41±054; PDA 0.97±0.64) than in asymptomatic groups (CON: 1.01±0.42; PDA: 0.60±0.45). Mean pSIRs of CON and PDA were significantly higher in patients with disk displacement without reduction (CON: 1.49±0.58; PDA: 1.07±0.66) than in patients with disk displacement with reduction (CON: 1.25±0.41, PDA: 0.75±0.55). Mean pSIR of CON was significantly lower in stage IIIa (1.17±0.43) than in stage IIIb (1.45±0.56) or IV (1.57±0.53). The pSIR obtained by SCE-MRI reflects clinical symptoms and offers potential diagnostic value in determining clinical stages and in follow-up for patients with TMDs. (author)

    Full Text Available Chronic temporomandibular disorder (TMD is known to have strong correlations with psychological factors and to display gender disparity. However, while chronic TMD is known to affect quality of life, large-scale studies investigating the influence on quality of life by gender are scarce.This cross-sectional study assessed the data of 17,198 participants aged ≥19 years who completed chronic TMD and EuroQol-5 Dimension sections in the 4th Korean National Health and Nutrition Examination Survey (2007-2009. We adjusted for covariates (health behavior, sociodemographic factors in regression analysis for complex sampling design to calculate regression coefficients and 95% CIs for gender difference in the association between chronic TMD and quality of life. We also evaluated which covariates of somatic health, mental health, health behavior, and sociodemographic factors weakened the relationship between TMD and EQ-5D.Prevalence of chronic TMD was 1.6% (men 1.3%, women 1.8%, and chronic TMD persisted to negatively impact quality of life even after adjusting for confounding variables. Low sociodemographic factors and health behavior had a negative effect on quality of life. Somatic health and mental health were most affected by chronic TMD. As for quality of life, women were affected to a greater extent than men by TMD. Women were more affected by osteoarthritis and general mental health (stress, depressive symptoms, and thoughts of suicide, and men by employment.These results imply that chronic diseases and psychological factors are important in chronic TMD, and that there may be physiological and pathological gender differences in TMD.

    A white female patient presented to the university clinic to obtain implant retained prostheses. She had an edentulous maxillary jaw and presented three teeth with poor prognosis (33, 34 and 43). The alveolar bone and the surrounding tissues were healthy. The patient did not report any relevant medical history contraindicating routine dental treatment or implant surgery, but self-reported a dental history of asymptomatic nocturnal bruxism. The treatment plan was set and two Branemark protocols supported by six implants in each arch were installed after a 6-month healing period. A soft occlusal splint was made due to the patient's history of bruxism, and the lack of its use by the patient resulted in an acrylic fracture. The prosthesis was repaired and the importance of using the occlusal splint was restated. In the 4-year follow-up no fractures were reported. PMID:24907215

    Numerous studies have investigated the relationship between depression and temporomandibular disorders (TMD), but the conclusions remain vague. The aim of this study was to examine the causal effect between depression and TMD.The reporting of this study conforms to the STROBE statement. In this retrospective cohort study, all samples were recruited from a representative subdataset of 1 million insured persons for the year 2005 Longitudinal Health Insurance Database, who were randomly selected from all beneficiaries enrolled in the National Health Insurance program of Taiwan. We used a propensity score and stratified 926,560 patients into 2 groups (propensity1 = 588,429 and propensity2 = 338,131) and 4 cohorts (propensity1 with depression = 18,038, propensity1 without depression = 570,391, propensity2 with depression = 38,656, propensity2 without depression = 299,475) to detect the development of TMD among the depressive and nondepressive patients between 2004 and 2013.The positive correlative factors of TMD included female, total number of times seeking medical advice (TTSMA) for anxiety state, TTSMA for generalized anxiety disorder, TTSMA for mandible fracture, and TTSMA for unspecified anomaly of jaw size. The propensity2 group was represented by elder and female-predominant patients who used more psychiatric health resources. Among 3 types of depression, only dysthymia (so-called chronic depression) had a causal impact on TMD in the propensity 2 group. In the propensity 2 group, the hazard ratio of dysthymia for TMD measured by Cox's regression was 1.64 (95% confidence interval 1.28-2.09), after adjusting for demographic factors, psychiatric comorbidities, and maxillofacial confounders. The first-onset mean time of TMD as the consequence of dysthymia was 3.56 years (sd = 2.74, min = 0.08, median = 2.99, max = 9.73).This study demonstrates that dysthymia increases the risk of TMD in elderly and female-predominant patients

    Sleep bruxism (SB) is a common sleep-related jaw motor disorder observed in 8% of the adult population. SB diagnosis is based on history of tooth grinding and clenching and is confirmed by the polysomnographic recording of the electromyographic activity of jaw muscles during sleep. SB may be associated with orofacial pain, headaches, and sleep-disordered breathing. Managing SB cannot be done without a comprehensive clinical and, when indicated, polysomnographic differential diagnosis of other comorbidities, which need to be taken into account to select the best treatment approach.

    The aim of the study was to evaluate changes in pain intensity and self-perceived quality of life in patients with temporomandibular disorders (TMD) during stabilization splint therapy. The hypothesis was that the clinical subtype of TMD, depending on whether pain is of muscular or temporomandibular joint origin, and pain chronicity (acute vs. chronic pain) differently affect treatment response. Thirty patients were included and treated with a stabilization splint in a 6-month clinical trial. Treatment outcomes included pain-free maximal mouth opening (MO), assisted maximal MO, path of MO, asymmetry in lateral excursions, spontaneous pain intensity (visual analog scale, VAS), and self-perceived quality of life (Oral Health Impact Profile, OHIP-14). Overall, VAS and OHIP-14 scores changed significantly over time (VAS: F = 80.85, p quality of life did not differ significantly between MP and DD groups (F = 0.213, p = 0.847, effect size = 0.008), or between AP and CP patients (F = 0.816, p = 0.489, effect size = 0.029). Linear regression analysis was used to assess the contribution of each predictor variable to the explanation of the OHIP summary score variance. Results showed pain reduction (coefficient = 0.303; 95% CI: 0.120 to 0.485) and MO increase (coefficient = 0.149; 95% CI: 0.037 to 0.260) to be independent predictors of the OHIP-14 summary score changes (R2 = 0.453), whereas other variables did not affect treatment outcome as assessed by OHIP-14. In conclusion, during 6-month stabilization splint therapy, significant changes in VAS and OHIP-14 summary scores were found. However, there were no significant differences in improvement rates between subjects with acute and chronic pain. Furthermore, no significant differences in improvement rates were found depending on whether pain was of muscular or temporomandibular joint origin. PMID:24974661

  6. Clinical evaluation of the low intensity laser antialgic action of GaAlAs (λ=785 nm) in the treatment of the temporomandibular disorders

    International Nuclear Information System (INIS)

    The therapy with laser emitting low intensity has been currently used in the most diverse fields of medicine as therapeutic conduct for pain. It is a non invasive, painless, non-thermal and aseptic type therapy, without any collateral effects, having a good cost/benefit relationship. However, for the therapy with low-intensity laser to result in positive effects, a correct diagnosis is fundamental, as well as a protocol of adequate application. n odontology, the majority of patients diagnosed with temporomandibular disorders (TMD), present pain and limitations in the movements of the jaw. In this work, a GaAlAs laser emitting low intensity, was used, λ=785 nm, in patients having a dysfunction of the temporomandibular joint with a complaint of pain. Twenty patients were divided into two groups. The group treated received laser therapy in the temporomandibular articulations and in the muscles affected. The dose applied was 45 J/cm2, while the ten patients in the control group received 0 J/cm2, in a total of nine applications, carried out three times a week, during three weeks. he evaluation of the patients was made through clinical examinations of manual palpation of the masseter, temporal, cervical, posterior neck and sternocleidomastoid muscles, and measurements of opening and laterality of the mouth. The results obtained showed a diminishing of the pain and an increase of the mandibular mobility in the patients treated, when compared to the control group. These results point to this therapy as being an important tool in the treatment of pain in patients with a dysfunction in the TMJ, indicating this therapeutic modality as a co-adjuvant in these treatments.

    Objective Osteoarthritis (OA) of the temporomandibular joint (TMJ) is generally thought to be an age-related disease like those of other joints. This study aims to investigate the incidence of computed tomographic (CT) OA changes in Korean temporomandibular disorder (TMD) patients diagnosed by the Research Diagnostic Criteria for TMD (RDC/TMD). Materials and methods The clinical records and radiographs of 1038 TMD patients (297 men and 741 women with mean age 31.1 ± 17.4 and 34.0 ± 16.2, respectively) diagnosed based on RDC/TMD Axis I in 2010 were reviewed. Results The incidence rate of OA changes in TMD patients is estimated to 27.3%, and higher in women than in men (15.5% in men and 32.0% in women) by 2.3 odds (p arthrosis/arthritis diagnosis based on RDC/TMD supplemented by plain radiographs shows high risk of OA changes on CT by 38.8 odds (p < 0.05). Conclusions These results imply that the OA changes in young Korean TMD patients are as common as in the old and have no correlation with clinical pain and noise. Considered with high prevalence of TMDs known in the young population, the overall/absolute OA changes in the TMJ can be even higher in the young than in the old population, not like in other joints.

    • BACKGROUND: Sleep bruxism is a common sleep disorder with unclear etiology and no definitive treatment. Recent
    • suggested medications are not often practically used due to their numerous limitations. Based on the fact that sleep bruxism occurs most often in the second stage of non-REM sleep, this study aimed to assess the effect of trazodone on sleep bruxism.
    • METHODS: This pilot study was conducted as a before-after design on 28 children and adolescents with 6-18 years of age suffering from sleep bruxism referring by children and adolescents mental health clinic, children dental specialists and pediatricians. The treatment started with 0.5mg/kg/day. In non-responders, it was weekly added by 0.5 mg/kg/day (with optimum of 2 mg/kg/day. Frequency of bruxism and related morning face/jaw pain were assessed daily from two weeks before (baseline to four weeks after starting the intervention by the parents/roommate.
    • RESULTS: Findings showed a significant reduction in the frequency of both bruxism and related morning pain from baseline to the 2nd and the 4th weeks of the intervention (P<0.001. Minor side effects such as drowsiness, nausea and dry mouth were seen among approximately one-third of the patients. These side effects were self-limited and tolerable.
    • CONCLUSIONS: Trazodone could be effective in reducing the frequency of sleep bruxism and its related morning face/jaw pain. Well-designed placebo-controlled trials are needed to confirm the results.

    Full Text Available This study evaluated the TMJ images of normal subjects and of those who presented TMD (temporomandibular disorders using linear tomography at rest position. Craniomandibular Index (CMI and a questionnaire on subjective symptoms were used to assess 217 subjects aged 12 to 18 years. Those with the highest and the lowest scores were divided into Control (n = 20 and TMD groups (n = 20, respectively. Corrected tomography was used to measure the narrowest anterior, superior and posterior joint spaces, to determine the condyle position in all 40 subjects. The distance means did not correlate with CMI scores (p > 0.05. The number of posteriorly positioned condyles was significantly higher in TMD patients (p = 0.05, especially in females. It was concluded that condyle position in linear tomography at rest position cannot yield TMD diagnosis.O objetivo deste estudo foi avaliar imagens da ATM de indivíduos portadores e não portadores de distúrbios temporomandibulares (DTM, através da tomografia linear corrigida na posição de repouso.

Foram selecionados 40 indivíduos com escores extremos, 20 sem DTM e 20 com DTM, para a formação dos grupos controle e DTM, respectivamente. Os espaços articulares anterior, superior e posterior foram mensurados pela tomografia corrigida, tendo como referência a região de menor comprimento subjetivo, determinando a posição condilar. As médias das distâncias não se correlacionaram com os escores do CMI (p > 0,05. O número de côndilos posteriorizados foi significativamente maior nos pacientes com DTM (p = 0,05, principalmente no sexo feminino.

    Patients with temporomandibular disorders (TMD) commonly experience myofascial and joint pain, pain-related disability, and other pain conditions including depression. The present study was carried out to explore the function of the hypothalamus-pituitary-adrenal (HPA) axis in relation to variables of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II and comorbid depression in female patients with TMD. Cortisol and dehydroepiandrosterone (DHEA) levels were determined in saliva samples that had been collected at various periods after waking (0, 30, and 60min) and at nighttime (2100-2200h) from 52 female patients with chronic TMD pain and age- and gender-matched controls (n=54, 20-40 years old). There were no significant differences in the levels and diurnal patterns of cortisol and DHEA secretion between groups of patients with TMD and controls. In patients, the cortisol awakening response (CAR) or diurnal cortisol rhythm were not associated with any variables of the RDC/TMD Axis II or the Beck Depression Inventory (BDI)-II total scores. However, the ratio of overall cortisol secretion within the first hour after waking (CARauc) to overall DHEA secretion during the post-waking period (Daucawk), defined as CARauc/Daucawk, was significantly associated with pain-related RDC/TMD variables (pain intensity and pain-related disability) and BDI-II total scores. Pain intensity and pain-related disability scores were also significantly associated with BDI-II total scores. These results indicated that an increase in molar cortisol/DHEA ratio due to the dissociation between cortisol and DHEA secretion was associated with pain intensity, pain-related disability, and depression in female patients with TMD.

    Context • Patients with fibromyalgia syndrome (FMS) report frequent and severe symptoms from temporomandibular disorders (TMDs). The appropriate treatment of TMDs remains controversial. No studies have occurred on the efficacy of therapy with a laser or an occlusal stabilization splint in the treatment of TMDs in patients with FMS. Objective • The study intended to investigate the therapeutic effects of laser therapy and of an occlusal stabilization splint for reducing pain and dysfunction and improving the quality of sleep in patients with TMDs and FMS. Design • The research team designed a single-blinded, randomized clinical trial. Setting • The study took place in the research laboratory at the University of Granada (Granada, Spain). Participants • Participants were 58 women and men who had been diagnosed with FMS and TMDs and who were referred from the clinical setting. Intervention • Participants were randomly assigned to the occlusal-splint or the laser group. The laser group received a treatment protocol in which laser therapy was applied to the participant's tender points, and the occlusal-splint group underwent a treatment protocol in which an occlusal stabilization splint was used. Both groups underwent treatment for 12 wk. Outcomes Measures • Pain intensity, widespread pain, quality of sleep, severity of symptoms, active and passive mouth opening, and joint sounds were assessed in both groups at baseline and after the last intervention. The measurements used were (1) a visual analogue scale (VAS), (2) the Widespread Pain Index (WPI), (3) the Symptom Severity Scale (SSS), (4) the Patient's Global Impression of Change (PGIC), (5) the Pittsburgh Quality of Sleep Questionnaire Index (PSQI), (6) an assessment of the number of tender points, (7) a measurement of the active mouth opening, (8) a measurement of the vertical overlap of the incisors, and (9) the measurement of joint sounds during mouth opening and closing.

    Mayer, Pierre; Heinzer, Raphael; Lavigne, Gilles

    2016-01-01

    Sleep bruxism (SB) consists of involuntary episodic and repetitive jaw muscle activity characterized by occasional tooth grinding or jaw clenching during sleep. Prevalence decreases from 20% to 14% in childhood to 8% to 3% in adulthood. Although the causes and mechanisms of idiopathic primary SB are unknown, putative candidates include psychologic risk factors (eg, anxiety, stress due to life events, hypervigilance) and sleep physiologic reactivity (eg, sleep arousals with autonomic activity, breathing events). Although certain neurotransmitters (serotonin, dopamine, noradrenalin, histamine) have been proposed to play an indirect role in SB, their exact contribution to rhythmic masticatory muscle activity (RMMA) (the electromyography marker of SB) genesis remains undetermined. No specific gene is associated with SB; familial environmental influence plays a significant role. To date, no single explanation can account for the SB mechanism. Secondary SB with sleep comorbidities that should be clinically assessed are insomnia, periodic limb movements during sleep, sleep-disordered breathing (eg, apnea-hypopnea), gastroesophageal reflux disease, and neurologic disorders (eg, sleep epilepsy, rapid eye movement behavior disorder). SB is currently quantified by scoring RMMA recordings in parallel with brain, respiratory, and heart activity recordings in a sleep laboratory or home setting. RMMA confirmation with audio-video recordings is recommended for better diagnostic accuracy in the presence of neurologic conditions. Management strategies (diagnostic tests, treatment) should be tailored to the patient's phenotype and comorbidities. In the presence of sleep-disordered breathing, a mandibular advancement appliance or CPAP treatment is preferred over single occlusal splint therapy on the upper jaw. PMID:26225899

    Bruxism is a diurnal or nocturnal parafunctional activity that includes tooth clenching, bracing, gnashing, and grinding. The dopaminergic system seems to be the key pathophysiology of bruxism and diminution of dopaminergic transmission at the prefrontal cortex seems to induce it. We report two patients with diurnal bruxism in whom a bilateral frontal lobe injury resulted from hemorrhagic stroke or traumatic brain injury. These patients' bruxism was refractory to bromocriptine but responded t...

    We report an unusual and rare cause of preauricular swelling and review the most recent literature concerning synovial osteochondromatosis of the temporomandibular joint. We report the clinical and radiologic findings of a case of synovial osteochondromatosis of the temporomandibular joint that presented as preauricular swelling in a female patient. This disease typically affects large joints; fewer than 100 cases reported in the literature affect the temporomandibular joint. This case illustrates that disorders of the temporomandibular joint should also be included in the differential diagnosis of patients who present with a preauricular mass.

    The reported prevalence of symptoms related to bruxism varies in the general population because of different investigative methodologies, operational definitions, clinical criteria, and samples of population. Awareness of bruxism in the general population is 15% to 23%, however, this rate increases to 50% to 90% in clinical studies. The aim of this study was to investigate the prevalence of self-reported symptoms associated with bruxism in Istanbul, Turkey and to analyze the correlation between bruxism and factors such as age, gender, marital status, and occupation. Seven-hundred-ninety-five (795) adult subjects who resided in the city of Istanbul were interviewed by telephone about their age, gender, marital status, occupation, and description of the prevalence of bruxism awareness. The overall prevalence of clenching teeth was 45.7% and that of grinding teeth was 21.6%. Women responded positively to the questions more often than men. The data showed significant differences between males and females, regarding clenching teeth OR: 1.41 (95% CI: 1.05-1.87), difficulty opening OR: 2.64 (95% CI: 1.63-4.26), headache on awakening OR: 2.28 (95% CI: 1.58-3.27) joint sounds OR: 1.72 (95% CI: 1.24-2.38), sore on awakening OR: 2.97 (95% CI: 1.91-4.61), influence in daily activity (OR: 2.26 CI: 1.38-3.67). Tooth wear in the married group was higher than the single group. Age distribution showed significant differences related to grinding teeth, tooth wear and joint sounds. There were statistically significant differences between bruxism and job categories. As a conclusion, this study suggest an association between bruxism and stressful events such as marital status and job problems. PMID:20491234

  13. Temporomandibular joint imaging

    International Nuclear Information System (INIS)

    The temporomandibular joint (TMJ) though close to the surface is one of the most difficult structures to visualise effectively. This is mainly due to the presence of dense bony structures which become superimposed over the image of the joint. The need to visualise this anatomical area is on the increase as more and more patients actively seek treatment for problems related to, and associated with, the craniomandibular articulation. Conventional radiographic techniques used to evaluate the joint have been designed to cope with the unique combination of hard and soft tissues and airspaces found in the maxillofacial region, but still have limitations. With the advent of the space age with its new materials, silicon chips and microcomputers, radiography has given way to diagnostic imaging which covers a range of modalities such as computerised tomography, magnetic resonance imaging, ultrasound and thermography. These are now available to assist in obtaining a clearer picture of the internal structures of the TMJ without the problems of superimposition previously encountered. This article is a resume of the radiographic techniques and a review of the current imaging methods available for assessing disorders of the temporomandibular joint. 21 refs., 3 tabs., 14 figs

    Full Text Available Background: Temporomandibular disorders (TMDs have been recognized as a common orofacial painful condition. Many epidemiological studies of TMDs in children and adolescents have been performed. However, the results of such studies have varied, and a comprehensive view of the prevalence and severity of symptoms and signs is difficult to obtain. Objectives: To determine the prevalence of signs and symptoms of TMDs among school children of Himachal Pradesh and to establish a baseline for comparison with future studies. Study Design: Cross sectional. Materials and Methods: A sample of 1188 school children in the age group of 9 and 12 years (males n = 650 and females n = 538, from randomly selected schools of rural and urban areas of Himachal Pradesh were included as study subjects. The survey was done according to the WHO Oral Health Assessment Form (modified. Results: The results of TMDs, i.e., clicking, tenderness and reduced jaw mobility showed that overall prevalence was 2.5% and the rest 96.5% were not suffering from these disorders. In 9 years age group, the prevalence was 1.6% whereas it was more than double, 3.5% in 12 years age group. Signs and symptoms of TMDs were determined to assess their oral health status. Statistical Analysis: SPSS version 15. Conclusion: This study contrasts with what is found in the other societies regarding the high prevalence of TMDs disorders.

    The oblique lateral transcranial projection (OLTP) of the temporomandibular joint (TMJ) is widely used for the diagnosis of TMJ disease. The OLTP is a simple and valuable technique for the lateral projection of the TMJ, but is sometimes reveals a complex radiographic findings due to the overlapping of the pars petrosa and the mastoid process to the TMJ. We have recently applied a photographic subtraction technique to the OLTP for reduction of the complex radiographic findings in the OLTP. The purpose of this study is to know the value of the photographic subtraction technique in the OLTP fundamentally. The results obtained are as follows: 1) The shape of the condyle was clearly demonstrated by the subtraction technique. 2) Diagnostic ability on disease of the condyle was increased by applying the subtraction technique. 3) Location of the condyle in the fossa was easily detected by the subtraction technique.

    Bruxism is a parafunctional activity related to clenching or grinding the teeth and tooth wear can be a consequence of sleep bruxism (SB). Management of severe tooth wear due to SB is a challenging situation because of the common reduced amount of remaining dental structure and loss of vertical dimension of occlusion. Rationale for the planning of oral rehabilitation of patients with SB presenting severe tooth wear should rely on evidence-based approaches; however, few studies have discussed properties of dental materials for SB rehabilitation and how to cosmetically manage severe tooth wear.

  3. Developing low-dose C-arm CT imaging for temporomandibular joint (TMJ) disorder in interventional radiology

    International Nuclear Information System (INIS)

    Manufacturers have provided C-arm CT imaging technologies for applications in interventional radiology in recent years. However, clinical imaging protocols and radiation doses have not been well studied or reported. The purpose of this study is to develop low-dose settings for clinically acceptable CT imaging of temporomandibular joint in interventional radiology suites, using a C-arm imaging angiography system. CT scans were performed with a flat-panel digital C-arm angiographic system on a 5-year-old anthropomorphic phantom. The CTDI was determined for various rotation times, dose settings and Cu filter selections. The CTDI values were compared with those of conventional low-dose CT for the same phantom. The effectiveness of using Cu filters to reduce dose was also investigated. Images were reviewed by a senior radiologist for clinical acceptance. The manufacturer's default setting gave an equivalent CTDI of 4.8 mGy. Optimizing the dose settings and adding copper filtration reduced the radiation dose by 94%. This represents a 50% reduction from conventional CT. Use of Cu filters and low-dose settings significantly reduced radiation dose from that of standard settings. This phantom study process successfully guided the clinical implementation of low-dose studies for all ages at our institution. (orig.)

    Bone changes in the mandibular head and mandibular fossa in 33 patients with temporomandibular joint (TMJ) disorders were studied with axial computed tomography in relation to clinical findings to clarify possible factors leading to bone changes in this phenomenon. Bone changes of the mandibular head were observed in 45 (68%) of the 66 TMJs. The mandibular head was juxtaposed to the mandibular fossa in 13 (29%) of the 45 joints in centric occlusion and in 29 joints (64%) in the anterior position on CT, whereas the mandibular head with no pathological bone change was juxtaposed to the mandibular fossa in none of the 21 joints in centric occlusion and in only 1 joint (5%) in the anterior position. In the two groups of patients with and without juxtaposition of the mandibular head and mandibular fossa with bone changes, the incidence of the initial symptoms such as pain, crepitus, and difficulty in opening the mouth was increased compared with the symptoms at presentation. However, the former group had severer symptoms than the latter group. These findings suggest that bony degeneration of the TMJ is accelerated by juxtaposition of the head and fossa. (author).

    Background This survey characterized the strategies used by general dentists to manage temporomandibular muscle joint disorders (TMJD) pain, and assessed the feasibility of doing a randomized clinical trial (RCT) of the effectiveness of these strategies. Methods Dentists from three Practice-Based Research Networks (PBRNs) specifically, DPBRN, PEARL, NWPRECEDENT) accepted to participate in this survey. Results Out of 862 dentists surveyed, 654 were general dentists who treat TMJD; among these, 80.3 percent stated they would participate in a RCT. Dentists treated an average of three pain-related TMJD patients per month. Splints (97.6 percent), self-care (85.9 percent) and over-the-counter or prescribed medications (84.6 percent) were the treatments most frequently used. The preferred treatments to compare in a RCT were splint therapy (35.8 percent), self-care (27.4 percent) and medications (16.9 percent). Conclusions Most general dentists treat TMJD pain, and reversible initial care is typically provided. Finally, it is feasible to conduct a RCT in the PBRNs to assess the effectiveness of splint therapy, medications and/or self-care, for the initial management of painful TMJD. Clinical Implications There is an opportunity to do a RCT in PBRNs leading to the development of evidence-based treatment guidelines for the initial treatment of pain-related TMJD by primary care dentists.

    The purposes of this study were to evaluate the relationship between correlation of MR joint effusion of the temporomandibular joint and disk position, to evaluate the relationship between joint effusion and aging, and to assess the frequency of MR joint effusion of bilateral temporomandibular joints. The temporomandibular joints of 192 patients with clinical symptoms of temporomandibular joint disorders were imaged bilaterally using high field, surface-coil MR imaging. Oblique sagittal and coronal proton density-weighted and T2-weighted images were obtained. Imaging findings of joint effusion were correlated with disk position, aging, and bilateral temporomandibular joints. MR showed effusion in 4% of the joints with normal superior disk position, 36% of the joints with disk displacement with reduction, and 45% of the joints with disk displacement without reduction. There were significant differences in the incidence of joint effusion between normal disk position and anterior disk displacement with or without reduction. Younger patients less than 40 years were significant higher the incidence of joint effusion than those of older patients. A significant association was seen between joint effusion and aging. MR showed effusion in 17% of the unilateral temporomandibular joint, 24% of the bilateral temporomandibular joints. There was no significant difference between unilateral and bilateral case. These results indicated that joint effusion using MR imaging was associated with varied temporomandibular joint pathologic states. (author)

    Objective To provide an update on what is known about bruxism and some of the major clinical highlights derived from new insights into this old problem in dentistry. Materials and methods A selective, non-systematic but critical review of the available scientific literature was performed. Results There are two main different types of bruxism, which are related to different circadian periods (sleep and awake bruxism) that may differ in terms of pathophysiology, but they share some common signs and symptoms. Approximately one out of 10 adult individuals may suffer from bruxism, but not all bruxers may need treatment. Bruxism is complicated to diagnose in the clinic and self-report of bruxism may not necessarily reflect the true presence of jaw muscle activity. Better understanding has been acquired of bruxism relationships with sleep stages, arousal responses and autonomic function with the help of polysomnography and controlled sleep studies. Meanwhile, there is still much more to learn about awake bruxism. With the available scientific knowledge it is possible to systematically assess the effects of bruxism and its potential risk factors for oral and general health. Moreover, we can be aware of the realistic possibilities to manage/treat the patient suffering from bruxism. Conclusion Bruxism is a parafunctional activity involving the masticatory muscles and probably it is as old as human mankind. Different ways have been proposed to define, diagnose, assess the impact and consequences, understand the pathophysiology and treat or manage bruxism. Despite the vast research efforts made in this field, there are still significant gaps in our knowledge. PMID:26758348

In total, 76.6% of the mothers, 40.2% of the fathers, and 48% of the children reported having bruxism. The participants believed that bruxism was associated with emotional factors (63.8% and/or mystical factors (20.4%. The majority reported having sought help from doctors (54.4%, followed by mystics (20.4% and dentists (19.1%. A statistically significant association was found between bruxism and children with restless sleep (P < 0.001 and in cases where both the parents and children were affected by bruxism (P < 0.001. Conclusion: Families require greater clarification regarding the factors that trigger bruxism.

  18. Dental wear caused by association between bruxism and gastroesophageal reflux disease: a rehabilitation report

    2007-08-01

    Full Text Available Bruxism is a pathological activity of the stomatognathic system that involves tooth grinding and clenching during parafunctional jaw movements. Clinical signs of bruxism are mostly related to dental wear and muscular and joint discomforts, but a large number of etiological factors can be listed, as local, systemic, psychological and hereditary factors. The association between bruxism, feeding and smoking habits and digestive disorders may lead to serious consequences to dental and related structures, involving dental alterations (wear, fractures and cracks, periodontal signs (gingival recession and tooth mobility and muscle-joint sensivity, demanding a multidisciplinary treatment plan. This paper presents a case report in which bruxism associated with acid feeding, smoking habit and episodes of gastric reflow caused severe tooth wear and great muscular discomfort with daily headache episodes. From the diagnosis, a multidisciplinary treatment plan was established. The initial treatment approach consisted of medical follow up with counseling on diet and smoking habits and management of the gastric disorders. This was followed by the installation of an interocclusal acrylic device in centric relation of occlusion (CRO for reestablishment of the occlusal stability, vertical dimension of occlusion, anterior guides and return to normal muscle activity (90-day use approximately. After remission of initial symptoms, oral rehabilitation was implemented in CRO by means of full resin composite restorations and new interocclusal device for protection of restorations. Satisfactory esthetics, improved function and occlusal stability were obtained after oral rehabilitation. The patient has attended annual follow-ups for the past 2 years. The multidisciplinary treatment seems to be the key for a successful rehabilitation of severe cases of dental wear involving the association of different health disorders.

  19. Internal derangement of the temporomandibular joint

    International Nuclear Information System (INIS)

    Internal Derangement is one of the most common disorders of the Temporomandibular joint. It is defined as an abnormal anatomical relationship between the discus articularis and the other structures of the temporomandibular joint. More than 2/3 of patients with clinical symptoms of the temporomandibular joint have an internal derangement. The most frequent finding in internal derangement is an anterior dislocation of the disc with reduction after mouth opening. In more severe cases a complete anterior dislocation is found without reduction of the disc. Internal derangement is a risk factor for developing osteoarthritis with remodeling of the condylus and the fossa mandibularis. The most important modalities of radiologic diagnosis are arthrography, CT and MRI. The diagnosis of craniofacial dysfunction has been improved dramatically by modern imaging techniques, which have become essential tools for primary diagnostic and evaluation after conservative or surgical therapy. MRI has become the gold standard. (orig.)

    The therapy with laser emitting low intensity has been currently used in the most diverse fields of medicine as therapeutic conduct for pain. It is a non invasive, painless, non-thermal and aseptic type therapy, without any collateral effects, having a good cost/benefit relationship. However, for the therapy with low-intensity laser to result in positive effects, a correct diagnosis is fundamental, as well as a protocol of adequate application. n odontology, the majority of patients diagnosed with temporomandibular disorders (TMD), present pain and limitations in the movements of the jaw. In this work, a GaAlAs laser emitting low intensity, was used, {lambda}=785 nm, in patients having a dysfunction of the temporomandibular joint with a complaint of pain. Twenty patients were divided into two groups. The group treated received laser therapy in the temporomandibular articulations and in the muscles affected. The dose applied was 45 J/cm{sup 2}, while the ten patients in the control group received 0 J/cm{sup 2}, in a total of nine applications, carried out three times a week, during three weeks. he evaluation of the patients was made through clinical examinations of manual palpation of the masseter, temporal, cervical, posterior neck and sternocleidomastoid muscles, and measurements of opening and laterality of the mouth. The results obtained showed a diminishing of the pain and an increase of the mandibular mobility in the patients treated, when compared to the control group. These results point to this therapy as being an important tool in the treatment of pain in patients with a dysfunction in the TMJ, indicating this therapeutic modality as a co-adjuvant in these treatments.

  3. Magnetic resonance signal intensity from retrodiscal tissue related to joint effusion status and disc displacement in elderly patients with temporomandibular joint disorders

    International Nuclear Information System (INIS)

    Magnetic resonance imaging (MRI) on patients with temporomandibular joint disorders (TMD) has revealed that a decrease and/or increase in signal intensity from retrodiscal tissue, joint effusion (the excessive accumulation of joint fluid) and articular disc displacement are related to TMD. However, the effect of aging on these phenomena has yet to be clarified. This study was carried out to explore the relationship between changes in signal intensity from retrodiscal tissue, joint fluid status and pathological disc conditions in elderly patients with TMD. Twenty patients aged over 60 years were examined. They consisted of one man and 19 women, and ranged between 60 and 79 years in age (mean, 66.0 years). The relationships between decreased signal intensity on proton-density-weighted (PDW) images and increased signal intensity on T2-weighted (T2W) MR images from retrodiscal tissue, joint fluid status and state of articular disc were examined. Joint fluid status was classified into 5 levels by extent of high signal areas in upper and lower articular spaces on T2W images. Disc displacement status was evaluated by PDW images. The Wilcoxon test was applied for the statistical analysis. The group showing increased T2W signal intensities from the retrodiscal tissue consisted of 31 out of 40 joints (77.5%). This group showed a significant difference in comparison with the other groups in which no apparent joint fluid was shown (p<0.05). There were no statistically significant differences among other categories. The results suggest a negative relationship between joint fluid and increased signal intensity from retrodiscal tissue due to reflection of the inflammatory reaction in TM joints. (author)

    The aim of this study was to examine the pathways between temporomandibular disorders (TMDs), occlusal characteristics, facial pain, and oral health-related quality of life in patients with severe malocclusion. The study comprised 94 (34 men and 60 women, mean age 38 years) adult patients who were referred for orthodontic or surgical-orthodontic treatment. All the patients had severe malocclusion. Oral health-related quality of life was measured with the Oral Health Impact Profile-14 scale (OHIP-14), the intensity of facial pain using a Visual Analogue Scale (VAS), TMD with Helkimo's clinical dysfunction index (Di), and occlusal characteristics with the Peer Assessment Rating (PAR). A hypothetical model of the interrelationships between these factors was constructed based on the conceptual model of biological, behavioural, and psychosocial consequences of oral diseases. The associations were studied with path analysis. Women reported poorer oral health-related quality of life, higher pain levels, and had more severe TMD than men, but the gender difference was statistically significant only in pain and TMD. In contrast to the hypothetical model, among women the occlusal characteristics were not directly associated with oral health-related quality of life or facial pain. Among men, the occlusal characteristics were directly associated with oral health-related quality of life. In conclusion, patients with severe malocclusion who also have TMD and facial pain more often have impaired oral health-related quality of life. The associations of the occlusal characteristics with oral health-related quality of life differ between genders. Therefore, these associations should be studied separately among genders.

    Using computerized pupillometry, our previous research established that the autonomic nervous system (ANS) is dysregulated in patients suffering from temporomandibular disorders (TMDs), suggesting a potential role for ANS dysfunction in pain modulation and the etiology of TMD. However, pain modulation hypotheses for TMD are still lacking. The periaqueductal gray (PAG) is involved in the descending modulation of defensive behavior and pain through μ, κ, and δ opioid receptors. Transcutaneous electrical nerve stimulation (TENS) has been extensively used for pain relief, as low-frequency stimulation can activate µ receptors. Our aim was to use pupillometry to evaluate the effect of low-frequency TENS stimulation of μ receptors on opioid descending pathways in TMD patients. In accordance with the Research Diagnostic Criteria for TMD, 18 females with myogenous TMD and 18 matched-controls were enrolled. All subjects underwent subsequent pupillometric evaluations under dark and light conditions before, soon after (end of stimulation) and long after (recovery period) sensorial TENS. The overall statistics derived from the darkness condition revealed no significant differences in pupil size between cases and controls; indeed, TENS stimulation significantly reduced pupil size in both groups. Controls, but not TMD patients, displayed significant differences in pupil size before compared with after TENS.

    Background: Multiple-language versions of the same psychometric instrument are increasingly needed, but simply translating an English version word-to-word into another language is not adequate to account for linguistic and cultural differences. Our aim was to alidate an Italian version of the Axis II of the Research Diagnostic Criteria for temporomandibular disorders (RDC/TMD and to test its reproducibility in order to use this important diagnostic instrument in Italian patients.

    Methods: The original English-language version was translated and culturally adapted for Italian-speaking people, back-translated to English and then tested on 68 subjects: 34 TMD patients and 34 healthy subjects. Internal consistency was assessed by calculating the Cronbach coefficient alpha for the entire scale in the two samples. The reproducibility of the domains was assessed with the use of the Spearman-Brown test-retest reliability test, Wilcoxon matched pair test, Sign test and 2x2table Chi Square test according to the data types. Correlation of the initial and test-retest scores of the Axis II was measured with the Spearman rank correlation coefficient as an additional measure of reproducibility.

    Results: The Italian version of Axis II has a good eproducibility; the internal consistency (measured with he Cronbach coefficient alpha of the overall final questionnaire was excellent: 0.95.

    Conclusions: The Axis II Italian version appeared reliable and it could be useful to assess TMD patients and to standardize the data acquisition in this relevant and common disease.

  7. Dysregulation of the descending pain system in temporomandibular disorders revealed by low-frequency sensory transcutaneous electrical nerve stimulation: a pupillometric study.

    Full Text Available Using computerized pupillometry, our previous research established that the autonomic nervous system (ANS is dysregulated in patients suffering from temporomandibular disorders (TMDs, suggesting a potential role for ANS dysfunction in pain modulation and the etiology of TMD. However, pain modulation hypotheses for TMD are still lacking. The periaqueductal gray (PAG is involved in the descending modulation of defensive behavior and pain through μ, κ, and δ opioid receptors. Transcutaneous electrical nerve stimulation (TENS has been extensively used for pain relief, as low-frequency stimulation can activate µ receptors. Our aim was to use pupillometry to evaluate the effect of low-frequency TENS stimulation of μ receptors on opioid descending pathways in TMD patients. In accordance with the Research Diagnostic Criteria for TMD, 18 females with myogenous TMD and 18 matched-controls were enrolled. All subjects underwent subsequent pupillometric evaluations under dark and light conditions before, soon after (end of stimulation and long after (recovery period sensorial TENS. The overall statistics derived from the darkness condition revealed no significant differences in pupil size between cases and controls; indeed, TENS stimulation significantly reduced pupil size in both groups. Controls, but not TMD patients, displayed significant differences in pupil size before compared with after TENS. Under light conditions, TMD patients presented a smaller pupil size compared with controls; the pupil size was reduced only in the controls. Pupil size differences were found before and during TENS and before and after TENS in the controls only. Pupillometry revealed that stimulating the descending opioid pathway with low-frequency sensory TENS of the fifth and seventh pairs of cranial nerves affects the peripheral target. The TMD patients exhibited a different pattern of response to TENS stimulation compared with the controls, suggesting that impaired

    There is a lack of knowledge about the effectiveness of manual therapy (MT) on subjects with temporomandibular disorders (TMD). The aim of this systematic review is to synthetise evidence regarding the isolated effect of MT in improving maximum mouth opening (MMO) and pain in subjects with signs and symptoms of TMD. MEDLINE(®) , Cochrane, Web of Science, SciELO and EMBASE(™) electronic databases were consulted, searching for randomised controlled trials applying MT for TMD compared to other intervention, no intervention or placebo. Two authors independently extracted data, PEDro scale was used to assess risk of bias, and GRADE (Grading of Recommendations Assessment, Development and Evaluation) was applied to synthetise overall quality of the body of evidence. Treatment effect size was calculated for pain, MMO and pressure pain threshold (PPT). Eight trials were included, seven of high methodological quality. Myofascial release and massage techniques applied on the masticatory muscles are more effective than control (low to moderate evidence) but as effective as toxin botulinum injections (moderate evidence). Upper cervical spine thrust manipulation or mobilisation techniques are more effective than control (low to high evidence), while thoracic manipulations are not. There is moderate-to-high evidence that MT techniques protocols are effective. The methodological heterogeneity across trials protocols frequently contributed to decrease quality of evidence. In conclusion, there is widely varying evidence that MT improves pain, MMO and PPT in subjects with TMD signs and symptoms, depending on the technique. Further studies should consider using standardised evaluations and better study designs to strengthen clinical relevance. PMID:26059857

    Objective:Bruxism is the term used for teeth grinding or jaw clenching. An electronic monitor of bruxism was developed to evaluate bruxism duration and frequency. Methods: Ten cases were selected in the Department of Prosthodontics of Jiangsu Stomatological Hospital to evaluate the monitor. A stabilization occlusal splint was fabricated for each of the 10 cases. The vertical dimension for each splint was 0.5 mm lower than mandibular postural position. Some sensors had been prearranged at each splint which could transfer the variation of the biting force into electronic signals. The data of sleeping duration, grinding duration and grinding frequency were recorded with this new type of bruxism monitor, which had been specifically invented to study bruxism. Results:The data from 10 bruxism cases were collected and the results were considered reliable. Subjects nocturnal duration parameters did not change significantly from night-to-night. Conclusion:The bruxiam monitor can automatically measure and record bruxism data using an occlusal splint. This device is valuable for diagnosis and evaluation of bruxism.

    Full Text Available Os fatores envolvidos na etiologia, diagnóstico e tratamento das desordens temporomandibulares (DTM de origem articular foram revisados. Critérios específicos de inclusão e exclusão para o diagnóstico de DTM são essenciais, mas apresentam utilidade limitada. Atualmente, os Critérios Diagnósticos de Pesquisa para Desordem Temporomandibular (RDC/TMD oferecem a melhor classificação baseada em evidências para os subgrupos mais comuns de DTM. O RDC/TMD inclui não apenas métodos para a classificação diagnóstica física, presentes em seu Eixo I, mas ao mesmo tempo métodos para avaliar a intensidade e a severidade da dor crônica e os níveis de sintomas depressivos e físicos não-específicos, presentes em seu Eixo II. Embora historicamente as más oclusões tenham sido consideradas como fatores de risco para o desenvolvimento das DTM, incluindo as predominantemente articulares, em muitos casos a associação estabelecida entre essas variáveis parece ter tomado direção oposta. No que diz respeito aos desarranjos internos da ATM, os resultados de estudos prévios sobre a redução induzida do ramo mandibular, secundária ao deslocamento anterior do disco articular, indicam que o reposicionamento do disco deslocado em crianças ou adolescentes jovens pode fazer mais sentido do que previamente imaginado. O uso terapêutico de suplementos alimentares, como o sulfato de glicosamina, parece uma alternativa segura ao uso dos medicamentos anti-inflamatórios normalmente utilizados para controlar a dor relacionada à osteoartrite da articulação temporomandibular (ATM, embora a evidência em torno de sua eficácia para a maioria dos pacientes de DTM não tenha sido completamente estabelecida.The authors reviewed the factors involved in the etiology, diagnosis and treatment of temporomandibular joint disorders (TMD.

    Full Text Available The aim of the present study was to investigate factors associated with bruxism in children aged from 1 to 13 years with developmental disabilities. A total of 389 dental records were examined. The bruxism analyzed was determined based on parental reports. The following variables were also analyzed: gender, age, International Code of Diseases (ICD, mouth breathing, history of gastroesophageal reflux, use of psychotropic drugs, gingival status, reports of xerostomia, hyperkinesis, pacifier use, thumb sucking and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without bruxism. Variables with a p-value < 0.25 in the bivariate analysis were incorporated into the logistic regression models. Females had a 0.44-fold (95%CI: 0.25 to 0.78 greater chance of exhibiting bruxism than males. Individuals with gastroesophageal reflux had a 2.28-fold (95%CI: 1.03 to 5.02 greater chance of exhibiting bruxism. Individuals with reported involuntary movements had a 2.24-fold (95%CI: 1.19 to 4.24 greater chance of exhibiting bruxism than those without such movements. Exhibiting involuntary movements, the male gender and gastroesophageal reflux are factors associated with bruxism in children with developmental disabilities.

    The aim of this study was to establish reference values for mandibular movements in 10- to 15-year-olds without dysfunction and compare these values to those in patients of the same age with tempromandibular disorders (TMD) and those found previously in a group of children younger than 11 years old without TMD. Children of both genders who visited the Department of Comprehensive Pediatric Dentistry at Buenos Aires University in 2013 and whose parents or guardians provided consent were evaluated using TMD/RDC by standardized pediatric dentists (Kappa 0.88). Three groups were formed according to diagnostic summary: Group C, without TMD; Group Ia, with myofascial pain, and Group Ib, pain with limited mouth opening. The following variables were analyzed: age, gender and mandibular movements. The sample included 169 patients aged 12.5±1.76 years, of whom 62.36% did not have TMD (C) while 37.27% were diagnosed with muscle disorder (29.58% Ia and 7.69% Ib). For Group C, the following values (in mm) were recorded: maximal unassisted opening: 48.28±6.14; right lateral movement 8.78±2.50; left lateral movement: 9.60±2.64; protrusion: 4.94±2.58 and overbite: 2.98 ± 2.5, with no variation associated to sex, but with differences in the values recorded for all movements compared to those obtained for mixed dentition (p=0.0001). Analysis of mean values for mandibular movements in all 3 groups only revealed differences for maximal unassisted opening (p= 0.0317). With relation to gender, TMD was more frequent in females, with significant differences between Groups C and Ia (p=0.019). In males without dysfunction, average maximal opening was 48.28±6.14mm, with lower values in patients with TMD. Mandibular movements in pediatric patients without TMD showed significant differences according to dentition type and age. PMID:27095624

    Full Text Available Although the etiopathophysiology of internal temporomandibular joint internal disorders (TMJ ID is still unknown, it has been suggested that head and body posture could be related to its initial onset, development and perpetuation. The purpose of the present study was to observe the relationship between cervical spine X-ray abnormalities and TMJ ID. This investigation evaluated 30 subjects with internal TMJ disorder symptoms (test group and 20 healthy subjects (control group. Subjects were submitted to clinical and radiographic evaluation. Clinical evaluation comprised anamnesis and stomatognathic system physical examination. Radiographic evaluation comprised analysis of lateral cervical spine X-rays by three physical therapists and tracing on the same im ages. The test group presented twice as much cervical spine hyperlordosis as the control group (20.7% versus 10.5%, but almost half of rectification prevalence (41.4 versus 79.0%, p = 0.03. After that, the test group was divided into three subgroups according to TMJ dysfunction severity, evaluated by Helkimo's index. These subgroups were not significantly different, but the subgroup with more severe TMD showed a tendency to cervical spine hyperlordosis prevalence. Results showed a tendency for subjects with more severe TMD to exhibit cervical spine hyperlordosis. Nevertheless, studies with a larger number of subjects suffering from severe TMD are encouraged in order to corroborate the present findings.Apesar de a etiofisiopatologia dos distúrbios internos (DI da articulação temporomandibular (ATM ser ainda desconhecida, sugere-se que as posturas de cabeça e corpo estariam associadas a seu desencadeamento, desenvolvimento e sua perpetuação.

Para isto, uma amostra de 45 indivíduos foi selecionada aleatoriamente e dividida em dois grupos. O grupo experimental foi formado por 24 pacientes, que apresentavam problemas articulares, e o grupo controle por 19 pacientes com ausência de qualquer relato ou queixa, compatível com DTM. Sessenta e sete por cento dos pacientes eram mulheres, com médias de idade de 36 anos. Os resultados da eletrovibratografia (EVG foram comparados com os obtidos pela palpação manual. Todos os examinadores desconheciam o grupo ao qual pertencia o paciente examinado. Para análise dos resultados de concordância, foi utilizado o teste de Cohen’s kappa e o percentual de concordância. Os resultados mostraram uma prevalência de 62,5% e 42,1% dos sons articulares, apresentados pelo grupo experimental e grupo controle, respectivamente. Pela análise dos resultados, concluiu-se que os sons articulares são comumente apresentados em ambos os grupos, porém sua identificação e classificação são difíceis, mesmo quando obtidos por aparelhos computadorizados. Embora a amostra deste estudo seja pequena, os resultados indicam que a EVG deve ser utilizada com cautela, e a calibração dos examinadores pode melhorar a identificação dos sons articulares.Both vibrational analysis and clinical examination have been claimed to identify intracapsular temporomandibular joint (TMJ disorders, particularly disc displacements.

    2015-01-01

    Full Text Available Rheumatoid arthritis (RA is a chronic, systemic, autoimmune inflammatory disorder that is characterized by joint inflammation, erosive properties and symmetric multiple joint involvement. Temporomandibular joint (TMJ is very rare to be affected in the early phase of the disease, thus posing diagnostic challenges for the dentist. Conventional radiographs fail to show the early lesions due to its limitations. More recently cone-beam computed tomography (CBCT has been found to diagnose the early degenerative changes of TMJ and hence aid in the diagnosis of the lesions more accurately. Our case highlights the involvement of TMJ in RA and the role of advanced imaging (CBCT in diagnosing the bony changes in the early phase of the disease.

  14. Efficacy of pumping manipulation treatment for closed lock of the temporomandibular joint disorder. Correlation between arthrographic findings using limited cone beam X-ray CT for dental use and mouth opening distance in 20 cases

    International Nuclear Information System (INIS)

    A study was conducted to evaluate the efficacy of pumping manipulation treatment for closed lock of the temporomandibular joint (TMJ) disorder using limited cone beam X-ray CT for dental use. The subjects were 20 patients with TMJ closed lock. Arthrography and pumping manipulation treatment were performed, and the correlation between maximal mouth opening and arthrographic findings was examined. Arthrography showed 16 cases of anterior disk displacement, and 4 cases of sideways displacement. Disk configuration showed 15 abnormal cases and 3 cases of disk perforation. Before treatment, mouth opening distance was 24.2 mm and 1 week after treatment it was 34.4 mm. After 3 months this had improved significantly to 41.0 mm. Comparison of mouth opening distance with arthrographic findings showed that disk perforation was significantly different after 3 months. These results suggest that pumping manipulation treatment might be useful in patients with TMJ closed lock without internal derangement or disk perforation. (author)

    Anxiety and selective serotonin reuptake inhibitors (SSRIs) are considered aggravating factors for bruxism. We examined the influence of anxiety, depression and SSRI on bruxism in social phobia (SP). Twenty-three drug naïve, 17 SSRI-treated SP patients and 33 healthy controls underwent a psychiatric assessment and completed Leibowitz Social Anxiety Scale and Beck Depression Inventory. Oral parafunctional activity (PF) was evaluated by TM-dental examination and by a questionnaire. Drug- naïve and SSRI-treated SP patients did not differ on demographic and clinical measures. Awake bruxism, 'JAW PLAY' and at least one PF were more prevalent in SP than in controls. Severity of SP predicted the presence of PF. SP, but not depression, was associated with higher risk of oral PF and awake bruxism. Chronic SSRI treatment of SP did not affect sleep and awake bruxism. Dental and anxiety screening may improve the prognosis psychiatric and dental patients. Effective treatment of SP may mitigate bruxism. PMID:25238249

  16. Surgery of temporomandibular joint under local anaesthesia

    2008-01-01

    Full Text Available Temporomandibular joint ankylosis is a debilitating disorder arising from an inability to open the mouth. This leads to poor nutrition, poor dental hygiene, and stunted growth. Anaesthesia, especially general anaesthesia, is very difficult to administer. There is a lack of direct visualization of the vocal cords, tongue fall following relaxation, and an already narrowed passage due to a small mandible, which makes even the blind nasal intubation difficult. There are various techniques described in literature to overcome these challenges, failing which, one needs to do tracheostomy. All the risks of difficult intubation and general anaesthesia can be avoided if the surgery is done under local anaesthesia. A simple but effective method of successful local anaesthesia is described, which allows successful temporomandibular joint reconstruction.

    TMDs are a complex collection of conditions which can have a significant impact on an individual's quality of life. The aetiology, diagnosis and management of TMDs will be described in this article with the hope of increasing a general dental practitioner's knowledge of these problems, thus helping them to institute simple, initial, conservative therapies for such patients. Diagnosis of TMDs can be simplified by following recent published clinical diagnostic criteria such as those outlined in this article. CPD/CLINICAL RELEVANCE: Pain and functional disturbances related to TMDs are common and require simple and pragmatic interventions for most patients. After providing a diagnosis, reassure patients that they do not have a sinister disease, and explain that the condition is usually self-limiting. PMID:27024901

  18. Temporomandibular joint computed tomography: development of a direct sagittal technique

    International Nuclear Information System (INIS)

    Radiology plays an important role in the diagnosis of temporomandibular disorders. Different techniques are used with computed tomography offering simultaneous imaging of bone and soft tissues. It is therefore suited for visualization of the articular disk and may be used in patients with suspected internal derangements and other disorders of the temporomandibular joint. Previous research suggests advantages to direct sagittal scanning, which requires special positioning of the patient and a sophisticated scanning technique. This study describes the development of a new technique of direct sagittal computed tomographic imaging of the temporomandibular joint using a specially designed patient table and internal light visor positioning. No structures other than the patient's head are involved in the imaging process, and misleading artifacts from the arm or the shoulder are eliminated. The use of the scanogram allows precise correction of the condylar axis and selection of exact slice level

    Full Text Available Se dispone de una extensa literatura científica que confirma que las disfunciones temporomandibulares (DTM presentan una mayor incidencia en mujeres. El objetivo de esta revisión es determinar si el proceso hormonal generado mediante el ciclo menstrual influye en las DTM que presentan sintomatología dolorosa. Se realizó una búsqueda de artículos científicos en las bases datos Medline, Embase, Scielo y CINAHL, entre los años 1970 y 2008. Se incluyeron estudios con diseños de cohortes y de casos y controles, donde se valoraron diversas variables del dolor durante el ciclo menstrual de personas que presentaban DTM. Dos revisores independientes valoraron la calidad de los estudios utilizando la Newcastle-Ottawa Scale. Se seleccionaron para el análisis cualitativo 4 estudios que cumplieron los criterios de inclusión propuestos. Los resultados de los estudios analizados son contradictorios, y por este motivo esta revisión no permite establecer conclusiones afirmativas en relación con el hecho que el factor hormonal femenino influye en la percepción del dolor en las DTM. Consideramos que es necesario realizar una mayor cantidad de estudios donde se investiguen los diversos aspectos del sexo femenino que puedan estar implicados en las DTM.A large body of evidence suggests that temporomandibular joint disorders (TMJD are much more prevalent in women than in men.

  8. Magnetic resonance in temporomandibular articulations

    International Nuclear Information System (INIS)

    Dysfunction of temporomandibular joint (TMJ) is extremely common, mainly in women. The indication of imaging study of TMJ is the evaluation of its internal derangements, since disc dislocation is treated by different way than other intrinsic mechanical conditions and of the painful myofacial dysfunction, as well where there is no anatomic lesion. The patients, who do not improve with the clinical approach, should be referred to imaging evaluation, in order to rule out mechanical disorder. When the patient is supposed to be operated upon, imaging of the contralateral TMJ is necessary. The presence of a thick and stiff disc perforated with adhesion to the mandibular condyle will change the surgical management. The plain x-ray film is able to demonstrate the bone outlines and joint space but it is not able to show the soft articular tissues. Arthrography is very reliable to demonstrate perforation. However it is an invasive method and demands skilled radiographer radiologist. MRI has shown to be reliable method and it is becoming to be progressively used in routine investigation of TMJ. Nevertheless, MRI still has some limitations concerning to disc perforation. (author). 16 refs, 9 figs

  12. The arterial blood supply of the temporomandibular joint: an anatomical study and clinical implications

    International Nuclear Information System (INIS)

    The aim of this study was to analyze three-dimensional images of the arterial supply to the temporomandibular joint. Ten patients (five men and five women, mean age 36 years) without signs or symptoms of temporomandibular disorders, who underwent contrast-enhanced computed tomographic (CT) scanning with intravenous contrast, were studied. The direct volume rendering technique of CT images was used, and a data set of images to visualize the vasculature of the human temporomandibular joint in three dimensions was created. After elaboration of the data through post-processing, the arterial supply of the temporomandibular joint was studied. The analysis revealed the superficial temporal artery, the anterior tympanic artery, the deep temporal artery, the auricular posterior artery, the transverse facial artery, the middle meningeal artery, and the maxillary artery with their branches as the main arterial sources for the lateral and medial temporomandibular joint. The direct volume rendering technique was found to be successful in the assessment of the arterial supply to the temporomandibular joint. The superficial temporal artery and maxillary artery ran along the lateral and medial sides of the condylar neck, suggesting that these arteries are at increased risk during soft-tissue procedures such as an elective arthroplasty of the temporomandibular joint.

    This study aimed to assess childhood bruxism relating associated factors and the bruxism's impact on oral health-related quality of life (OHRQoL). A case-control study was performed with 3- to 6-year-old children obtained from public preschools in Brazil. The case and control groups had 21 and 40 children, respectively. Associations between bruxism and respiratory problems (p = 0.04, OR: 0.33, CI: 0.09 to 1.14), dental wear (p 0.05). The association between presence and absence of impact with bruxism or other variables showed no statistical relationship (p > 0.05). It could be concluded that childhood bruxism is related to respiratory problems, dental wear, dental caries, and malocclusion. Despite being a topic that demands special care in dentistry, bruxism does not significantly affect the OHRQoL. PMID:26388123

    Full Text Available OBJECTIVE: This study aimed to evaluate the possibility of any correlation between disc displacement and parameters used for evaluation of skull positioning in relation to the cervical spine: craniocervical angle, suboccipital space between C0-C1, cervical curvature and position of the hyoid bone in individuals with and without symptoms of temporomandibular dysfunction. MATERIAL AND METHODS: The patients were evaluated following the guidelines set forth by RDC/TMD. Evaluation was performed by magnetic resonance imaging for establishment of disc positioning in the temporomandibular joints (TMJs of 30 volunteer patients without temporomandibular dysfunction symptoms and 30 patients with symptoms. Evaluation of skull positioning in relation to the cervical spine was performed on lateral cephalograms achieved with the individual in natural head position. Data were submitted to statistical analysis by Fisher's exact test at 5% significance level. To measure the degree of reproducibility/agreements between surveys, the kappa (K statistics was used. RESULTS: Significant differences were observed between C0-C1 measurement for both symptomatic (p=0.04 and asymptomatic (p=0.02. No statistical differences were observed regarding craniocervical angle, C1-C2 and hyoid bone position in relation to the TMJs with and without disc displacement. Although statistically significant difference was found in the C0-C1 space, no association between these and internal temporomandibular joint disorder can be considered. CONCLUSIONS: Based on the results observed in this study, no direct relationship could be determined between the presence of disc displacement and the variables assessed.

Methods The Helkimo index was used to analyze the anam nestic(Ai) and clinical(Di) data of 123 preoperative cases with severe maxillo- mandibular deformities. Results 1. The incidence of symptom of TMD in the patient group with diverse severe dentofacial deformities was higher tha n the control group. The most frequent symptom was clicking or other joint sound s. Pain originating from muscle or TMJ and limiation of jaw movement were the ne xt two commonest symptoms. The incidence of signs of TMD in the patient group wa s not found to be different from the controls. 2. Clicking or other joint sounds were reported more often in female patients than male. In contrast with it the palpation tenderness from the TMJ was found more often in male. The incidence of limitation of jaw movement was higher in younger patients than older, but most mild. The symptom of TMJ sounds was significantly correlated with asymmetry defo rmity. The lateral movement mobility of the asymmetry patients was reduced in th e deviation side. The more impaired mandibular mobility of the patients with man dibular retrusion suggested that their TMDs were severe. Conclusion The temporomandibular joint function of patients with severe maxillofacial deformities is different from that of normal peole.

    Full Text Available Headache could be a symptom of many disturbances or alterations influencing mastication system. It had been reported that one out of three persons had experienced severe headache in his or her lige. According to many research, 70% patients with temporomandibular disorder has a recurrent headache symptom. Furthermore, a temporomandibular disorder with headache could be resulted from alteration in occlusion. Unfortunately, examination for occlusal disturbances that cause temporomandibular disorder is often neglected. Many dentists assume that patient with such a symprom should consult a physician since it is beyond his area of treatment. This present study is aimed to look for any relationship between alteration in radiographic imaging of temporomandibular joint, and occlusal disturbance in individuals with headacehe symptom, using questioners and study models. The study also includes clinical examination to see any alteration in occlusal function, and radiograph of temporomandibular joint to see any differences from normal. Data that had been collected is analyzed by statistical analysis to find relationship between the two variables.

    Full Text Available BACKGROUND: Tasks can be instruments of stress and may affect the health of children. Sleep bruxism is a multifactorial sleep-related movement disorder that affects children and adults. The aim of the present study was to analyze the association between children's tasks, personality traits and sleep bruxism. METHODS AND FINDINGS: A cross-sectional, population-based study of 652 randomly selected Brazilian schoolchildren (52% of whom were female, aged from 7 to 10 years was conducted in the city of Belo Horizonte, Brazil. A questionnaire based on criteria proposed by the American Academy of Sleep Medicine (AASM was completed by parents. In addition, the Neuroticism and Responsibility sub-scales of the Big Five Questionnaire for Children (BFQ-C were administered to the children. Psychological tests were administered and evaluated by psychologists. The Social Vulnerability Index from the city council database was used to determine the social classification of the families. Chi-square and Poisson regression statistical tests were used with a 95% confidence interval. The majority of families were classified as having low social vulnerability (61.3%, whereas, 38.7% were classified as having high social vulnerability. Regarding extracurricular activities, the majority of girls performed household work (56.4% and some artistic activity (51.3% while sporting activities were most common among boys (61%. The results of the Poisson regression model indicated that sleep bruxism was most prevalent in children who scored highly in the Neuroticism sub-scale, and who frequently performed household tasks. CONCLUSION: Children whose personality domain has a high level of Neuroticism and who perform household chores imposed by the family are more vulnerable to sleep bruxism.
